Scnn1 sodium channel gene family in genetically engineered mice.

The amiloride-sensitive epithelial sodium channel is the limiting step in salt absorption. In mice, this channel is composed of three subunits (alpha, beta, and gamma), which are encoded by different genes (Scnn1a, Scnn1b, and Scnn1c, respectively). The functions of these genes were recently investigated in transgenic (knockout) experiments, and the absence of any subunit led to perinatal lethality. More defined phenotypes have been obtained by introducing specific mutations or using transgenic rescue experiments. In this report, these approaches are summarized and a current gene-targeting strategy to obtain conditional inactivation of the channel is illustrated. This latter approach will be indispensable for the investigation of channel function in a wide variety of organ systems.

Evolution of the P-type II ATPase gene family in the fungi and presence of structural genomic changes among isolates of Glomus intraradices.

BACKGROUND: The P-type II ATPase gene family encodes proteins with an important role in adaptation of the cell to variation in external K+, Ca2+ and Na2+ concentrations. The presence of P-type II gene subfamilies that are specific for certain kingdoms has been reported but was sometimes contradicted by discovery of previously unknown homologous sequences in newly sequenced genomes. Members of this gene family have been sampled in all of the fungal phyla except the arbuscular mycorrhizal fungi (AMF; phylum Glomeromycota), which are known to play a key-role in terrestrial ecosystems and to be genetically highly variable within populations. Here we used highly degenerate primers on AMF genomic DNA to increase the sampling of fungal P-Type II ATPases and to test previous predictions about their evolution. In parallel, homologous sequences of the P-type II ATPases have been used to determine the nature and amount of polymorphism that is present at these loci among isolates of Glomus intraradices harvested from the same field. RESULTS: In this study, four P-type II ATPase sub-families have been isolated from three AMF species. We show that, contrary to previous predictions, P-type IIC ATPases are present in all basal fungal taxa. Additionally, P-Type IIE ATPases should no longer be considered as exclusive to the Ascomycota and the Basidiomycota, since we also demonstrate their presence in the Zygomycota. Finally, a comparison of homologous sequences encoding P-type IID ATPases showed unexpectedly that indel mutations among coding regions, as well as specific gene duplications occur among AMF individuals within the same field. CONCLUSION: On the basis of these results we suggest that the diversification of P-Type IIC and E ATPases followed the diversification of the extant fungal phyla with independent events of gene gains and losses. Consistent with recent findings on the human genome, but at a much smaller geographic scale, we provided evidence that structural genomic changes, such as exonic indel mutations and gene duplications are less rare than previously thought and that these also occur within fungal populations.

Provenance and family variation of Pinus caribaea var. hondurensis from Guatemala and Honduras, grown in Brazil, Colombia and Venezuela

Pinus caribaea var. hondurensis (Sénécl) Barr. & Golf. is a tropical pine that naturally occurs in lowland areas of Belize, El Salvador, Guatemala, Honduras, Nicaragua, and eastern Mexico. It has been one of the most studied tropical pines and the one with the most commercial importance in Brazil. The objective of this work was to select the best provenances for plantations and best trees in families for the establishment of seed orchards. For that a trial with five provenances and 47 open-pollinated families was planted near Planaltina, Federal District, in the Cerrado Region of Brazil. The provenances tested were Poptun (Guatemala), Gualjoco, Los Limones, El Porvenir and Santa Cruz de Yojoa (Honduras) and assessed at 12 years of age. Poptun and Gualjoco had larger volume, and Los Limones and El Porvenir the lowest incidence of forks and foxtails. Individual tree heritabilities for volume, stem form and branch diameter were 0.34, 0.06, and 0.26 respectively. More than 90% of the trees had defects, common in unimproved P. caribaea. Selection criteria for quality traits need to be relaxed in the first generation of breeding to allow for larger genetic gains in productivity. Results from this test compared with P. caribaea var. hondurensis trials in other Brazilian, Colombian and Venezuelan sites suggest that provenance x site and family x site interactions are not as strong as in other pine species.

Role of AP-1 family members in lymphomagenesis

Constitutive activation of the nuclear factor-KB (NF-KB) transcriptional pathway is the main characteristic of the activated B-cell-like (ABC) subtype of diffuse large B- cell lymphoma (DLBCL). This has been attributed to oncogenic mutations in the CARMA1, CD79A/B, MyD88 or RNF31 signaling proteins, which control NF-kB activation at different levels. Since several of these mutations lead to a state that mimics chronically antigen receptor-stimulated B-cells, and since the antigen receptor also triggers other transcription pathways, these might be important in ABC DLBCL malignancy too. In this study we analyzed whether abnormal expression and activity of members of the AP-1 transcription factor family could contribute to the pathogenesis of ABC DLBCL. Here, we identified activation of Jun as well as ATF members of the dimeric AP-1 transcription factor family, as a hallmark of ABC but not of germinal center B- cell-like (GCB) DLBCL cell lines. ABC DLBCL cell lines harbored an upregulated expression of c-Jun, JunB, JunD and ATF3 proteins. We could show that the upregulation of c-Jun, JunB and ATF3 was dependent on constitutive BCR and MyD88 signaling. Since AP-1 transcription factors need to dimerize to be active, Jun binding partners were investigated and we could demonstrate the presence of several ATF/Jun heterodimers (including c-Jun/ATF2, c-Jun/ATF3, c-Jun/ATF7, JunB/ATF2, JunB/ATF3, JunB/ATF7, JunD/ATF2, JunD/ATF3 and JunD/ATF7 heterodimers). The disruption of ATF/Jun heterodimers by A-Fos, a dominant negative form of Jun members, was toxic to ABC but not to GCB DLBCL cell lines. Finally, ATF3 immunohistochemistry on DLBCL patient samples revealed that samples classified as non-GCB had more intense and preferentially nuclear staining of ATF3, which could be of diagnostic relevance since the histological classification of the ABC and GCB DLBCL subtypes is difficult in clinical practice. In conclusion, we could show that ABC DLBCL are not only addicted to NF-KB signaling, but also to signaling by some members of the AP-1 transcription factor family. Thus, the AP-1 pathway might be a promising therapeutic target for the treatment of ABC DLBCL. Additionally, monitoring ATF3 levels could improve the diagnosis of ABC DLBCL by IHC. -- L'activation constitutive du facteur de transcription NF-KB est l'une des caractéristiques principales des lymphomes B du type ABC-DLBCL. Cette addiction est dépendante de mutations oncogéniques de CARMA1, CD79A/B, MyD88 et RNF31 qui contrôlent NF-KB à différents niveaux. Etant donné que la plupart de ces mutations mène à un état d'activation chronique du récepteur des cellules B (BCR) et que le BCR active d'autres voies de signalisation, d'autres facteurs de transcription pourraient être impliqués dans la lymphomagénèse des ABC-DLBCL. Dans cette étude, nous nous sommes demandé si les membres de la famille du facteur de transcription AP-1 contribuaient à la pathogénèse de ce type de lymphome. Dans des lignées cellulaires de lymphomes du type ABC-DLBCL en comparaison avec le type GCB-DLBCL, nous avons pu identifier une activation anormale de plusieurs membres de la famille Jun et ATF, deux sous-familles du facteur de transcription AP-1. Les lignées cellulaires dérivées de lymphomes du type ABC-DLBCL surexpriment les facteurs de transcription c-Jun, JunB, JunD et ATF3. Leur surexpression dépend de l'activation constitutive de la voie du BCR et de MyD88. Etant donné qu'AP-1 requiert la formation de dimères pour être actif, nous nous sommes intéressés aux partenaires d'interactions de c-Jun, JunB et JunD et avons pu montrer la formation de plusieurs hétérodimères Jun/ATF (incluant les hétérodimères c-Jun/ATF2, c-Jun/ATF3, c-Jun/ATF7, JunB/ATF2, JunB/ATF3, JunB/ATF7, JunD/ATF2, JunD/ATF3 et JunD/ATF7). Lorsque l'on empêche la formation de ces hétérodimères avec A-Fos, un dominant négatif des membres Jun, la survie des lignées cellulaires du type ABC-DLBCL est diminuée, tandis que les lignées cellulaires GCB-DLBCL ne sont pas affectées. Pour finir, des immunohistochimies (IHC) pour ATF3 sur des échantillons de patients classifiés comme GCB et non-GCB ont pu montrer une coloration d'ATF3 nucléaire et beaucoup plus intense que les échantillons du type GCB. Ainsi, ATF3 pourrait être potentiellement utile en clinique pour différencier le sous type non-GCB des GCB. En conclusion, nous avons pu montrer que les lymphomes du type ABC- DLBCL ne présentent pas uniquement une addiction à NF-KB, mais également de certains membres de la famille de facteur de transcription AP-1. Par conséquent, AP- 1 pourrait être une cible thérapeutique prometteuse pour le développement de futures stratégies. En outre, la détermination des niveaux d'ATF3 par IHC pourraient améliorer le diagnostic des patients du type ABC DLBCL.

Iowa Historic Property Study of the Zeman Barn, 2009

The Zeman Barn (86-00028) is an early twentieth-century example of a gothic roofed barn and is part of the Zeman Farmstead located along U.S. Highway 30 in Otter Creek Township (Township 38N, Range 14W), Tama County, Iowa (Figures 1 and 2). The farmstead was initially evaluated in a reconnaissance architectural survey conducted in 1998 by The Louis Berger Group, Inc (Berger). An intensive architectural survey of the property by Berger’s Principal Architectural Historian, Martha H. Bowers, evaluated the farmstead as not being eligible for listing in the National Register of Historic Places (National Register) but noted that the barn appears to be eligible for listing in the National Register under Criterion C (Bowers 1998). At the request of the Iowa Department of Transportation, Berger completed the recordation project to provide a documentary record of the Zeman Barn in accordance with the guidelines set forth by the Iowa State Historic Preservation Office regarding historic property studies for barns. Background research for this project was conducted in September 2008 and April 2009. The property was inspected and photographed in May 2008. Information on the property was gathered through background research, interviews with Zeman family members, field investigation, and photo documentation. Historical maps of the project area were used to collect data necessary for developing regional and local historic contexts. The research for this report was conducted at the Tama County Courthouse and the Tama County Historical Museum Genealogical Library, both in Toledo. Much of the background research for the project was conducted by Camilla Deiber and Michael Dulle. Ms. Deiber also prepared the photographic documentation, plan drawings, and the graphics used in this report. Mr. Roger L. Ciuffo conducted interviews with Zeman family members and wrote this report.

The family alliance assessment scales : steps toward validity and reliability of an observational assessment tool for early family interactions

We present the first steps in the validation of an observational tool for father-mother-infant interactions: the FAAS (Family Alliance Assessment Scales). Family-level variables are acknowledged as unique contributors to the understanding of the socio-affective development of the child, yet producing reliable assessments of family-level interactions poses a methodological challenge. There is, therefore, a clear need for a validated and clinically relevant tool. This validation study has been carried out on three samples: one non-referred sample, of families taking part in a study on the transition to parenthood (normative sample; n = 30), one referred for medically assisted procreation (infertility sample; n = 30) and one referred for a psychiatric condition in one parent (clinical sample; n = 15). Results show that the FAAS scales have (1) good inter-rater reliability and (2) good validity, as assessed through known-group validity by comparing the three samples and through concurrent validity by checking family interactions against parents' self-reported marital satisfaction.

Failure to thrive in a girl born into a family affected by familial dysalbuminemic hyperthyroxinemia

Autosomal dominant familial dysalbuminemic hyperthyroxinemia (FDH)is characterized by modified human serum albumin (HSA) inducing asubstantially higher affinity for thyroxine (T4). Histidin or prolinsubstitution on residue R218 produces localized conformationalchanges of HSA creating additional room for T4 binding, leadingto 14-20 fold normal total T4 (TT4) levels. Affected individuals areconsidered euthyroid. Our patient is an 18 months-old swiss girl bornto a mother known for the rare R218P mutation in the HSA gene.She presented with severe failure to thrive (height -2.92 SD, weight-3.6 SD), habitual hip dislocation without anatomical anomaly, latefontanelle closing and protruding ears. Psychomotor development isslightly retarded. Thyroid function testing confirmed extremely high TT4(1446.0 nmol/l) levels, which are similar to her brother's values (1534.4nmol/l and 1757.6 nmol/l respectively). Free T4 seems slightly elevated(26 pmol/l), probably due to methodological reasons. TSH (0.92 mU/l),free T3 (4.4 pmol/l) and thyroxin binding globulin (32 mg/l) are withinthe normal range. Her two half-brothers, affected by the samemutation, are now 18.7 (P1) and 16.6 (P2) years old and wereoriginally described by S. Pannain et al. in 2000. Both werecharacterized by growth retardation (-2.1 and -2.2 SD) before the ageof 4 years. P1 has reached a normal adult height (-0.4 SD) and P2has caught up to normal growth (-0.68 SD) with moderate bonematuration delay. Pubertal development and anterior pituitary functionare adequate. Primary growth and developmental retardation in thefirst years of life with adequate catch-up seem to be a distinctcharacteristic in FDH with R218P mutation. Hip dislocation is typicallyseen in other situations associated to thyroid disorders, like Downsyndrome. These findings might be explained by altered early thyroidhormone utilization in children with FDH.

Preservation of rhizobia by lyophilization with trehalose

The objective of this study was to determine if trehalose can effectively enhance the viability and storage lifetime of Rhizobium tropici and Rhizobium etli after lyophilization as compared to the traditional protective combination of sucrose and peptone. Two strains of bean-nodulating rhizobia were effectively preserved in the lyophilized state by 100 mM trehalose, and survived for at least 12 days, even when stored under non-ideal conditions. Trehalose provided better protection than the sucrose/peptone combination. When protective excipients were introduced inside the cells, strain CFN 42 was more sensitive to the type of additive used than strain CIAT 899, probably because CIAT 899 produces beta (1-2) glucan, which may have a protective effect. beta (1-2) glucan combined with sucrose protected better than trehalose against leakage from freeze-dried liposomes, but by itself it had no protective capability. There was a high level of unfrozen water associated with the hydrated glucan, in addition to a thermal event at approximately 70ºC, corresponding to an observed gel-sol transition in the glucan. These findings may shed light on the mechanism by which the glucan contributes to the protection of dried cells and liposomes, and may lead to further improvements in rhizobial inoculants.
