Characterization of BMP signaling in breast development and tumorigenesis

Résumé L'influence des hormones reproductives sur le développement du cancer du sein a été établie au travers de nombreuse études épidémiologiques. Nous avons précédemment démontré que le gène Wnt-4 est un médiateur essentiel de la progestérone dans le développement lobulo-alvéolaire de l'épithélium mammaire. De plus, le rôle de la voie de signalisation Wnt dans la tumorigénèse de la glande mammaire mutine est largement établi. Pour comprendre sa fonction dans le cancer du sein, nous avons activée cette voie en surexprimant le gène Wnt-1 dans des cellules épithéliales primaires de sein, au moyen d'un rétrovirus. Ceci a conduit à la transformation oncogénique de ces cellules et à l'obtention d'un modèle de carcinogénèse du sein dénommé Wnt-1 HMEC. L'analyse de l'expression des gènes induits par la surexpression de Wnt-1 dans ces cellules, a permis d'identifier les gènes BMP4 et 7. Alors que des analyses de RT-PCR ont montré leur forte expression dans les cellules Wnt-1-HMECs, la présence d'une grande quantité de la protéine BMP7 a été constatée dans les tumeurs dérivées de ces cellules. L'importante phosphorylation des Smad 1, 5, S dans les Wnt-1 HMECs indique l'activation de la voie BMP, possiblement due à la stimulation ce celle-ci par BMP7. L'activation de la voie Wnt par la ß-Caténine, conduit à la transcription de BMP7, identifiant ainsi ce gène comme un gène cible de la voie canonique. La pertinence de nos observations a par ailleurs été confirmée par le fait que BMP7 est surexprimé dans les tumeurs de seins humains. Afin d'élucider la fonction de la voie BMP dans le sein, nous avons utilisé le modèle mutin. L'expression du gène BMP7 dans les souris transgéniques MMTV Wnt-1 s'est avérée élevée, démontrant qu'il est aussi un gène cible de la voie Wnt in-vivo. L'expression de l'ARN messager .codant pour la protéine BMP7 est induite lors du développement lobulo-alvéolaire, qui se fait sous l'influence de la progestérone et de Wnt-4. Ensemble, ces observations corroborent le fait qu'une stimulation avec de la progestérone suffit à induire la transcription du gène dans les 24h. Nos résultats coïncident d'autre part avec le fait que BMP7 est exprimé dans la couche myoépithéliale de l'épithélium où la voie Wnt est activée. L'analyse de souris reportrices de l'activité de la voie BMP, suggère une activation dans la couche luminale de l'épithélium durant tout le développement de la glande mammaire. Curieusement, cette même voie est active dans le mésenchyme lors de la mammogénèse embryonnaire. Finalement, nos analyses d'immunofluorescence démontrent la capacité de prolifération des cellules ayant activé BMP, ainsi que leur nette ségrégation d'avec les cellules exprimant le récepteur à la progestérone. Nos résultats démontrent que le gène BMP7 est un gène cible de la voie Wnt canonique dans le sein. Son expression dans la couche myoépitheliale est induite par Wnt-4, lui-même sécrété par les cellules luminales sensibles à la progestérone. La sécrétion de la protéine BMP7 conduit finalement à l'activation de la voie BMP dans les cellules négatives pour le récepteur à la progestérone. Abstract Epidemiological studies highlight the repetitive exposure to circulating progesterone as a major risk in the development of breast cancer. Work in our laboratory showed that Wnt-4 is an essential mediator of progesterone-driven side-branch formation, while Wnt signaling has long been established as strongly oncogenic in the mouse mammary gland. To address the role of Wnt in breast tumorigenesis we activated the pathway in primary human breast epithelial cells by means of refroviral Wnt-1 expression. This resulted in a Wnt1-induced breast carcinogenesis model, being referred to as Wnt-1-HMECs. Gene expression profiling revealed the Bone Morphogenetic Protein 4 and 7 (BMP4 and 7) a mong the most upregulated gene by ectopic Wnt-1 expression in primary HMECs. RT-PCR analysis confirmed elevated BMP4 and 7 mRNA levels in Wnt-1-infected HMECs, as well as strong BMP7 expression in the tumors derived from these cells. Smad 1, 5, 8 phosphorylation was high in Wnt-1HMECs whereas below detection limit in primary HMECs suggesting that the increased expression of BMP-7 results in activation of downstream signaling. Ectopic expressíon of a stabilized form of ßcatenin in primary HMECs resulted in increased transcription of BMP-7 suggesting that it is a target of canonical Wnt signaling. The clinical relevance of our observations was confirmed by the finding of BMP7 being upregulated in human breast tumor samples. To elucidate the role of BMP ligands in the breast in-vivo, we made use of the mouse model. Expression of the BMP7 gene was found to be increased in MMTV-Wnt-1 transgenic animals, suggesting that BMP7 may also be a Wnt 1 target gene in vivo. Expression of BMP7 was upregulated in mid-pregnancy which coincides with progesterone/Wnt induced side branching. BMP7 was induced within 24 hours by progesterone. Consistent with it being a target of canonical Wnt signaling, we demonstrated preferential expression of this ligand in the myoepithelial cells, the target cells of Wnt signals. In-vivo analysis of BMP signaling using a reporter mouse revealed the activation of the pathway in the luminal layer of the epithelium throughout postnatal development. Interestingly, during embryonic mammogenesis the pathway was found to be active in the mesenchyme. Immunofluorescence studies demonstrated that cells with BMP activity can proliferate. They also revealed a clear segregation between progesterone receptor positive cells and cells with active BMP signaling. Together our observations suggest that BMP-7 is a canonical Wnt signaling target both in HMECs and in the mouse mammary gland in-vivo. It is expressed in the myoepithelium possibly in response to Wnt-4, which is secreted by steroid receptor positive cells in response to progesterone. BMP-7 in turn may impinge on lumina) epithelial cells and activate BMP signaling in PR negative cells.

The application of cDNA and tissue microarray methods in the study of human carcinomas

Currently, numerous high-throughput technologies are available for the study of human carcinomas. In literature, many variations of these techniques have been described. The common denominator for these methodologies is the high amount of data obtained in a single experiment, in a short time period, and at a fairly low cost. However, these methods have also been described with several problems and limitations. The purpose of this study was to test the applicability of two selected high-throughput methods, cDNA and tissue microarrays (TMA), in cancer research. Two common human malignancies, breast and colorectal cancer, were used as examples. This thesis aims to present some practical considerations that need to be addressed when applying these techniques. cDNA microarrays were applied to screen aberrant gene expression in breast and colon cancers. Immunohistochemistry was used to validate the results and to evaluate the association of selected novel tumour markers with the outcome of the patients. The type of histological material used in immunohistochemistry was evaluated especially considering the applicability of whole tissue sections and different types of TMAs. Special attention was put on the methodological details in the cDNA microarray and TMA experiments. In conclusion, many potential tumour markers were identified in the cDNA microarray analyses. Immunohistochemistry could be applied to validate the observed gene expression changes of selected markers and to associate their expression change with patient outcome. In the current experiments, both TMAs and whole tissue sections could be used for this purpose. This study showed for the first time that securin and p120 catenin protein expression predict breast cancer outcome and the immunopositivity of carbonic anhydrase IX associates with the outcome of rectal cancer. The predictive value of these proteins was statistically evident also in multivariate analyses with up to a 13.1- fold risk for cancer specific death in a specific subgroup of patients.

Memory mixed with desire : a preliminary study of philosophy and literature in the works of Friedrich Nietzsche and Milan Kundera

Memory Mixed with Desire: A preliminary study of Philosophy and Literature in the works of Friedrich Nietzsche and Milan Kundera Robert Spinelli Brock University, Department of Philosophy This thesis studies intertextuality in the works of Friedrich Nietzsche and Milan Kundera through the primary themes of memory and forgetting. The thesis starts with two introductory chapters that delineate memory according to Nietzsche and Kundera respectively. From here, I move into a discussion of Nietzsche's Ubermensch as an example of the type of forgetting that Nietzsche sees as a cure for the overabundance of memory that has led to Christian morality. Next, I explore the Kunderan concept of kitsch as the polar opposite of what Nietzsche has sought in his philosophy, finishing the chapter by tying the two thinkers together in a Kunderan critique of Nietzsche. The thesis ends with a chapter devoted to the Eternal Return beginning with an exegesis of Nietzsche's idea and ending with a similar exegesis of Kundera's treatment of this thought. What I suggest in this chapter is that the Eternal Return might itself be a form of kitsch even in its attempt to revalue existence.

The aluminium content of breast tissue taken from women with breast cancer

The aetiology of breast cancer is multifactorial. While there are known genetic predispositions to the disease it is probable that environmental factors are also involved. Recent research has demonstrated a regionally specific distribution of aluminium in breast tissue mastectomies while other work has suggested mechanisms whereby breast tissue aluminium might contribute towards the aetiology of breast cancer. We have looked to develop microwave digestion combined with a new form of graphite furnace atomic absorption spectrometry as a precise, accurate and reproducible method for the measurement of aluminium in breast tissue biopsies. We have used this method to test the thesis that there is a regional distribution of aluminium across the breast in women with breast cancer. Microwave digestion of whole breast tissue samples resulted in clear homogenous digests perfectly suitable for the determination of aluminium by graphite furnace atomic absorption spectrometry. The instrument detection limit for the method was 0.48 μg/L. Method blanks were used to estimate background levels of contamination of 14.80 μg/L. The mean concentration of aluminium across all tissues was 0.39 μg Al/g tissue dry wt. There were no statistically significant regionally specific differences in the content of aluminium. We have developed a robust method for the precise and accurate measurement of aluminium in human breast tissue. There are very few such data currently available in the scientific literature and they will add substantially to our understanding of any putative role of aluminium in breast cancer. While we did not observe any statistically significant differences in aluminium content across the breast it has to be emphasised that herein we measured whole breast tissue and not defatted tissue where such a distribution was previously noted. We are very confident that the method developed herein could now be used to provide accurate and reproducible data on the aluminium content in defatted tissue and oil from such tissues and thereby contribute towards our knowledge on aluminium and any role in breast cancer.

Fine needle aspiration (FNA) cytology of pilomatrixoma: report of 14 cases and review of the literature

We describe 14 cases of pilomatrixoma which were diagnosed preoperatively on FNA cytology. In contrast to the literature, our series showed male preponderance and some of the tumours in unusual locations such as thigh and breast. In three patients the rumours were larger than 5 cm. The clinical diagnosis varied from tumour not otherwise defined to sarcoma. The cytologic presentation had features which allowed a correct diagnosis in all cases and included basaloid cells surrounded by delicate pink fibres, shadow cells, giant cells, naked nuclei and calcium deposits. It is concluded that the FNA cytology of pilomatrixoma is characteristic and will allow a conclusive diagnosis even in cases with an aberrant clinical presentation.

Foucauldian Panopticism: The Gaze in Selected 19th Century Literature

Throughout history, women have often been perceived as hysterical and weak. This perception has been reflected through the representation of women in literature which has resulted in a limited scope of female normality and morality creating characteristics fundamentally different than male characters. Though these characteristics have been contributed as natural female characteristics, the theories of Jeremy Bentham, a 18th and 19th century Englishman, can be applied as a possible reason for these reactions. Bentham’s Panopticon, the theory of punishment wherein a constant unseen gaze peers at inmates theoretically creating paranoia and psychological breakdown, creates characteristics similar to those that women in literature seem to exhibit. In this paper, I will outline the characteristics of three various characters in novels. First, I will review the Panoptic literature that has been written on The Woman in Charlotte Perkins Gilman’s The Yellow Wallpaper, then I will conduct my own analysis on The Governess in Henry James’ The Turn of the Screw and Jane Eyre in Charlotte Bronte’s Jane Eyre . In this analysis, I will consider the “gaze,” the symbolic Panopticon implemented by society, and argue how characteristics present in stereotypical representations of women are not inherent in women due to gender or sex, but because women are most objectified and thereby most affected by the Panoptic gaze of society.

Mitochondrial dysfunction in a cell model of thyroid oncocytoma

The role of mitochondrial dysfunction in cancer has long been a subject of great interest. In this study, such dysfunction has been examined with regards to thyroid oncocytoma, a rare form of cancer, accounting for less than 5% of all thyroid cancers. A peculiar characteristic of thyroid oncocytic cells is the presence of an abnormally large number of mitochondria in the cytoplasm. Such mitochondrial hyperplasia has also been observed in cells derived from patients suffering from mitochondrial encephalomyopathies, where mutations in the mitochondrial DNA(mtDNA) encoding the respiratory complexes result in oxidative phosphorylation dysfunction. An increase in the number of mitochondria occurs in the latter in order to compensate for the respiratory deficiency. This fact spurred the investigation into the presence of analogous mutations in thyroid oncocytic cells. In this study, the only available cell model of thyroid oncocytoma was utilised, the XTC-1 cell line, established from an oncocytic thyroid metastasis to the breast. In order to assess the energetic efficiency of these cells, they were incubated in a medium lacking glucose and supplemented instead with galactose. When subjected to such conditions, glycolysis is effectively inhibited and the cells are forced to use the mitochondria for energy production. Cell viability experiments revealed that XTC-1 cells were unable to survive in galactose medium. This was in marked contrast to the TPC-1 control cell line, a thyroid tumour cell line which does not display the oncocytic phenotype. In agreement with these findings, subsequent experiments assessing the levels of cellular ATP over incubation time in galactose medium, showed a drastic and continual decrease in ATP levels only in the XTC-1 cell line. Furthermore, experiments on digitonin-permeabilised cells revealed that the respiratory dysfunction in the latter was due to a defect in complex I of the respiratory chain. Subsequent experiments using cybrids demonstrated that this defect could be attributed to the mitochondrially-encoded subunits of complex I as opposed to the nuclearencoded subunits. Confirmation came with mtDNA sequencing, which detected the presence of a novel mutation in the ND1 subunit of complex I. In addition, a mutation in the cytochrome b subunit of complex III of the respiratory chain was detected. The fact that XTC-1 cells are unable to survive when incubated in galactose medium is consistent with the fact that many cancers are largely dependent on glycolysis for energy production. Indeed, numerous studies have shown that glycolytic inhibitors are able to induce apoptosis in various cancer cell lines. Subsequent experiments were therefore performed in order to identify the mode of XTC-1 cell death when subjected to the metabolic stress imposed by the forced use of the mitochondria for energy production. Cell shrinkage and mitochondrial fragmentation were observed in the dying cells, which would indicate an apoptotic type of cell death. Analysis of additional parameters however revealed a lack of both DNA fragmentation and caspase activation, thus excluding a classical apoptotic type of cell death. Interestingly, cleavage of the actin component of the cytoskeleton was observed, implicating the action of proteases in this mode of cell demise. However, experiments employing protease inhibitors failed to identify the specific protease involved. It has been reported in the literature that overexpression of Bcl-2 is able to rescue cells presenting a respiratory deficiency. As the XTC-1 cell line is not only respiration-deficient but also exhibits a marked decrease in Bcl-2 expression, it is a perfect model with which to study the relationship between Bcl-2 and oxidative phosphorylation in respiratory-deficient cells. Contrary to the reported literature studies on various cell lines harbouring defects in the respiratory chain, Bcl-2 overexpression was not shown to increase cell survival or rescue the energetic dysfunction in XTC-1 cells. Interestingly however, it had a noticeable impact on cell adhesion and morphology. Whereas XTC-1 cells shrank and detached from the growth surface under conditions of metabolic stress, Bcl-2-overexpressing XTC-1 cells appeared much healthier and were up to 45% more adherent. The target of Bcl-2 in this setting appeared to be the actin cytoskeleton, as the cleavage observed in XTC-1 cells expressing only endogenous levels of Bcl-2, was inhibited in Bcl-2-overexpressing cells. Thus, although unable to rescue XTC-1 cells in terms of cell viability, Bcl-2 is somehow able to stabilise the cytoskeleton, resulting in modifications in cell morphology and adhesion. The mitochondrial respiratory deficiency observed in cancer cells is thought not only to cause an increased dependency on glycolysis but it is also thought to blunt cellular responses to anticancer agents. The effects of several therapeutic agents were thus assessed for their death-inducing ability in XTC-1 cells. Cell viability experiments clearly showed that the cells were more resistant to stimuli which generate reactive oxygen species (tert-butylhydroperoxide) and to mitochondrial calcium-mediated apoptotic stimuli (C6-ceramide), as opposed to stimuli inflicting DNA damage (cisplatin) and damage to protein kinases(staurosporine). Various studies in the literature have reported that the peroxisome proliferator-activated receptor-coactivator 1(PGC-1α), which plays a fundamental role in mitochondrial biogenesis, is also involved in protecting cells against apoptosis caused by the former two types of stimuli. In accordance with these observations, real-time PCR experiments showed that XTC-1 cells express higher mRNA levels of this coactivator than do the control cells, implicating its importance in drug resistance. In conclusion, this study has revealed that XTC-1 cells, like many cancer cell lines, are characterised by a reduced energetic efficiency due to mitochondrial dysfunction. Said dysfunction has been attributed to mutations in respiratory genes encoded by the mitochondrial genome. Although the mechanism of cell demise in conditions of metabolic stress is unclear, the potential of targeting thyroid oncocytic cancers using glycolytic inhibitors has been illustrated. In addition, the discovery of mtDNA mutations in XTC-1 cells has enabled the use of this cell line as a model with which to study the relationship between Bcl-2 overexpression and oxidative phosphorylation in cells harbouring mtDNA mutations and also to investigate the significance of such mutations in establishing resistance to apoptotic stimuli.

Molecular analysis of special type breast carcinomas

The project was developed into three parts: the analysis of p63 isoform in breast tumours; the study of intra-tumour eterogeneicity in metaplastic breast carcinoma; the analysis of oncocytic breast carcinoma. p63 is a sequence-specific DNA-binding factor, homologue of the tumour suppressor and transcription factor p53. The human p63 gene is composed of 15 exons and transcription can occur from two distinct promoters: the transactivating isoforms (TAp63) are generated by a promoter upstream of exon 1, while the alternative promoter located in intron 3 leads to the expression of N-terminal truncated isoforms (ΔNp63). It has been demonstrated that anti-p63 antibodies decorate the majority of squamous cell carcinomas of different organs; moreover tumours with myoepithelial differentiation of the breast show nuclear p63 expression. Two new isoforms have been described with the same sequence as TAp63 and ΔNp63 but lacking exon 4: d4TAp63 and ΔNp73L, respectively. Purpose of the study was to investigate the molecular expression of N-terminal p63 isoforms in benign and malignant breast tissues. In the present study 40 specimens from normal breast, benign lesions, DIN/DCIS, and invasive carcinomas were analyzed by immunohistochemistry and RT-PCR (Reverse Transcriptase-PCR) in order to disclose the patterns of p63 expression. We have observed that the full-length isoforms can be detected in non neoplastic and neoplastic lesions, while the short isoforms are only present in the neoplastic cells of invasive carcinomas. Metaplastic carcinomas of the breast are a heterogeneous group of neoplasms which exhibit varied patterns of metaplasia and differentiation. The existence of such non-modal populations harbouring distinct genetic aberrations may explain the phenotypic diversity observed within a given tumour. Intra-tumour morphological heterogeneity is not uncommon in breast cancer and it can often be appreciated in metaplastic breast carcinomas. Aim of this study was to determine the existence of intra-tumour genetic heterogeneity in metaplastic breast cancers and whether areas with distinct morphological features in a given tumour might be underpinned by distinct patterns of genetic aberrations. 47 cases of metaplastic breast carcinomas were retrieved. Out of the 47 cases, 9 had areas that were of sufficient dimensions to be independently microdissected. Our results indicate that at least some breast cancers are composed of multiple non-modal populations of clonally related cells and provide direct evidence that at least some types of metaplastic breast cancers are composed of multiple non-modal clones harbouring distinct genetic aberrations. Oncocytic tumours represent a distinctive set of lesions with typical granular cytoplasmatic eosinophilia of the neoplastic cells. Only rare example of breast oncocytic carcinomas have been reported in literature and the incidence is probably underestimated. In this study we have analysed 33 cases of oncocytic invasive breast carcinoma of the breast, selected according to morphological and immunohistochemical criteria. These tumours were morphologically classified and studied by immunohistochemistry and aCGH. We have concluded that oncocytic breast carcinoma is a morphologic entity with distinctive ultrastructural and histological features; immunohistochemically is characterized by a luminal profile, it has a frequency of 19.8%, has not distinctive clinical features and, at molecular level, shows a specific constellation of genetic aberration.

Software zur automatischen Tumordiagnose in der funktionalen MRT der weiblichen Brust

In den westlichen Industrieländern ist das Mammakarzinom der häufigste bösartige Tumor der Frau. Sein weltweiter Anteil an allen Krebserkrankungen der Frau beläuft sich auf etwa 21 %. Inzwischen ist jede neunte Frau bedroht, während ihres Lebens an Brustkrebs zu erkranken. Die alterstandardisierte Mortalitätrate liegt derzeit bei knapp 27 %.rnrnDas Mammakarzinom hat eine relative geringe Wachstumsrate. Die Existenz eines diagnostischen Verfahrens, mit dem alle Mammakarzinome unter 10 mm Durchmesser erkannt und entfernt werden, würden den Tod durch Brustkrebs praktisch beseitigen. Denn die 20-Jahres-Überlebungsrate bei Erkrankung durch initiale Karzinome der Größe 5 bis 10 mm liegt mit über 95 % sehr hoch.rnrnMit der Kontrastmittel gestützten Bildgebung durch die MRT steht eine relativ junge Untersuchungsmethode zur Verfügung, die sensitiv genug zur Erkennung von Karzinomen ab einer Größe von 3 mm Durchmesser ist. Die diagnostische Methodik ist jedoch komplex, fehleranfällig, erfordert eine lange Einarbeitungszeit und somit viel Erfahrung des Radiologen.rnrnEine Computer unterstützte Diagnosesoftware kann die Qualität einer solch komplexen Diagnose erhöhen oder zumindest den Prozess beschleunigen. Das Ziel dieser Arbeit ist die Entwicklung einer vollautomatischen Diagnose Software, die als Zweitmeinungssystem eingesetzt werden kann. Meines Wissens existiert eine solche komplette Software bis heute nicht.rnrnDie Software führt eine Kette von verschiedenen Bildverarbeitungsschritten aus, die dem Vorgehen des Radiologen nachgeahmt wurden. Als Ergebnis wird eine selbstständige Diagnose für jede gefundene Läsion erstellt: Zuerst eleminiert eine 3d Bildregistrierung Bewegungsartefakte als Vorverarbeitungsschritt, um die Bildqualität der nachfolgenden Verarbeitungsschritte zu verbessern. Jedes kontrastanreichernde Objekt wird durch eine regelbasierte Segmentierung mit adaptiven Schwellwerten detektiert. Durch die Berechnung kinetischer und morphologischer Merkmale werden die Eigenschaften der Kontrastmittelaufnahme, Form-, Rand- und Textureeigenschaften für jedes Objekt beschrieben. Abschließend werden basierend auf den erhobenen Featurevektor durch zwei trainierte neuronale Netze jedes Objekt in zusätzliche Funde oder in gut- oder bösartige Läsionen klassifiziert.rnrnDie Leistungsfähigkeit der Software wurde auf Bilddaten von 101 weiblichen Patientinnen getested, die 141 histologisch gesicherte Läsionen enthielten. Die Vorhersage der Gesundheit dieser Läsionen ergab eine Sensitivität von 88 % bei einer Spezifität von 72 %. Diese Werte sind den in der Literatur bekannten Vorhersagen von Expertenradiologen ähnlich. Die Vorhersagen enthielten durchschnittlich 2,5 zusätzliche bösartige Funde pro Patientin, die sich als falsch klassifizierte Artefakte herausstellten.rn

Transnationalism and Identity: the Concept of Community in Ghanaian Literature and Contemporary Ghanaian Culture

In my thesis, I use anthropology, literature, and adinkra, an indigenous art, to study Ghanaian concepts of community from an interactive standpoint. While each of these disciplines has individually been used to study the concept of community, the three have not previously been discussed in relation to one another. I explore the major findings of each field—mainly that in anthropology, transnational informants find communities upheld; in literature, transnational characters find the opposite; and in adinkra, there are elements of both continuity and dissolution—to discuss Ghanaian constructs of community in the transnational world. Throughout time, there have always been transnational individuals and concepts, but as globalization continues, transnationalism has become an ever-more vital topic, and combined with the common anthropological discussion of tradition and modernity, its influence on developing countries, like Ghana, is significant. Therefore, in my thesis, I explore how differing conceptions of community present themselves in each discipline, and how those divergences create a new understanding of place and identity.
