Maternal Obesity in the UK: Findings from a national project

In 2008, the Confidential Enquiry into Maternal and Child Health (CEMACH), now known as the Centre for Maternal and Child Enquiries (CMACE), commenced a 3-year UK-wide Obesity in Pregnancy project. The project was initiated in response to a number of factors. At the time, these included: i) growing evidence that obesity is associated with increased morbidity and mortality for both mother and baby, ii) evidence from the CEMACH 'Saving Mothers' Lives' report showed that women with obesity were over-represented among those who died of direct deaths compared to those who died of indirect deaths, 1 iii) unknown national and regional prevalence rates of maternal obesity, and iv) the need for a national clinical guideline for the care of women with obesity in pregnancy.

Glucose and leptin induce apoptosis in human beta-cells and impair glucose-stimulated insulin secretion through activation of c-Jun N-terminal kinases.

c-Jun N-terminal kinases (SAPK/JNKs) are activated by inflammatory cytokines, and JNK signaling is involved in insulin resistance and beta-cell secretory function and survival. Chronic high glucose concentrations and leptin induce interleukin-1beta (IL-1beta) secretion from pancreatic islets, an event that is possibly causal in promoting beta-cell dysfunction and death. The present study provides evidence that chronically elevated concentrations of leptin and glucose induce beta-cell apoptosis through activation of the JNK pathway in human islets and in insulinoma (INS 832/13) cells. JNK inhibition by the dominant inhibitor JNK-binding domain of IB1/JIP-1 (JNKi) reduced JNK activity and apoptosis induced by leptin and glucose. Exposure of human islets to leptin and high glucose concentrations leads to a decrease of glucose-induced insulin secretion, which was partly restored by JNKi. We detected an interplay between the JNK cascade and the caspase 1/IL-1beta-converting enzyme in human islets. The caspase 1 gene, which contains a potential activating protein-1 binding site, was up-regulated in pancreatic sections and in isolated islets from type 2 diabetic patients. Similarly, cultured human islets exposed to high glucose- and leptin-induced caspase 1 and JNK inhibition prevented this up-regulation. Therefore, JNK inhibition may protect beta-cells from the deleterious effects of high glucose and leptin in diabetes.

Survival responses in stressed organs

Apoptosis or programmed cell death is a regulated form of cell suicide executed by cysteine proteases, or "caspases", to maintain proper tissue homeostasis in multicellular organisms. Dysregulation of apoptosis leads to pathological complications including cancer, autoimmunity, neurodegenerative, and heart diseases. Beside their known function as the key executioners of apoptotic cell death, caspases were reported to mediate non-apoptotic functions. In this report we study the survival signals conveyed through caspase-3-mediated cleavage of Ras GTPase-activating proteins (RasGAP). Ubiquitously expressed, RasGAP senses caspase activity and controls the cell death/survival switch. RasGAP is cleaved once at low caspase activity and the generated N-terminal fragment (fragment N) induces a survival response by activating Ras/PI3K/Akt pathway. However, high caspase activity associated with increased stress leads to fragment Ν cleavage into fragments that do not mediate any detectable survival signals. In this thesis project we studied the role of fragment Ν in protecting stressed organs as well as in maintenance of their functionality. In response to stress in different organs, we found that mice lacking caspase-3 or unable to cleave RasGAP (Knock-In mice), and therefore unable to generate fragment N, were deficient in Akt activation and experienced increased apoptosis compared to wild-type mice. Augmented tissue damage and organ dysfunction in those mice highlight the importance of fragment Ν in activating Akt-mediated prosurvival pathway and in protection of organs during episodes of stress. In parallel we investigated the role of fragment Ν in regulating the activation of transcription factor NF-kB, a master regulator of inflammation. Sustained NF-kB activation may be detrimental by directly causing apoptosis or leading to a persistent damaging inflammation response. We found that fragment Ν is a potent inhibitor of NF-kB by favoring its nuclear export. Therefore, fragment Ν regulates NF-kB activity and contributes to a controlled response as well as maintenance of homeostasis in stressed cells. Importantly, these findings introduce new insights of how activated caspase-3 acts as a stress intensity sensor that controls cell fate by either initiating a fragment N- dependent cell resistance program or a cell suicide response. This identifies the pivotal role of fragment Ν in protection against patho-physiological damage, and encourages the development of therapies which aim to increase cell resistance to vigorous treatment. - L'apoptose, ou mort cellulaire programmée, est une forme contrôlée de suicide cellulaire exécuté par des protéines appelées caspases, dans le but de maintenir l'homéostasie des tissus sains dans les organismes multicellulaires. Un mauvais contrôle de l'apoptose peut mener à des pathologies comme le cancer, la neurodégénération et les maladies cardiaques et auto-immunes. En dehors de leur rôle connu d'exécutrices de l'apoptose, les caspases ont aussi été identifiées dans d'autres contextes non-apoptotiques. Dans ce projet, nous avons étudié les signaux de survie émis par le résultat du clivage de RasGAP par la caspase-3. Exprimée de façon ubiquitaire, RasGAP est sensible à l'activité de caspase-3 et contrôle la décision de la cellule à entreprendre la mort ou la survie cellulaire. A un taux d'activité faible, la caspase-3 clive RasGAP, ce qui mène à la génération d'un fragment N-terminal, appelé Fragment N, qui induit des signaux de survie via l'activation de la cascade Ras/PI3K/Akt. Cependant, lorsque l'activité de la caspase-3 augmente, le fragment N est clivé, ce qui a pour effet d'éliminer ces signaux de survie. Dans ce travail, nous avons étudié le rôle du Fragment N dans la protection des organes en état de stress et dans le maintien de leur fonctionnalité. En réponse à certains stress, nous avons découvert que les organes de souris n'exprimant pas la caspase-3 ou alors incapables de cliver RasGAP (souris Kl), et de ce fait n'ayant pas la possibilité de générer le Fragment N, perdaient leur faculté d'activer la protéine Akt et démontraient un taux d'apoptose plus élevé que des organes de souris sauvages. Le fait que les organes et tissus de ces souris manifestaient de graves dommages et dysfonctions met en évidence l'importance du Fragment N dans l'activation des signaux de survie via la protéine Akt et dans la neutralisation de l'apoptose induite par la caspase-3. En parallèle, nous avons investigué le rôle du Fragment N dans la régulation de l'activation de NF-kB, un facteur de transcription clé dans l'inflammation. Une activation soutenue de NF-kB peut être délétère par activation directe de l'apoptose ou peut mener à une réponse inflammatoire persistante. Nous avons découvert que le Fragment N, en favorisant l'export de NF-kB depuis le noyau, était capable de l'inhiber très efficacement. Le Fragment N régule donc l'activité de NF-kB et contribue au maintien de l'homéostasie dans des cellules stressées. Ces découvertes aident, de façon importante, à la compréhension de comment l'activation de la caspase-3 agit comme senseur de stress et décide du sort de la cellule soit en initiant une protection par le biais du fragment N, ou en induisant un suicide cellulaire. Cette étude définit le Fragment Ν comme ayant un rôle de pivot dans la protection contre des dommages patho-physiologiques, et ouvre des perspectives de développement de thérapies qui cibleraient à augmenter la résistance à divers traitements.

Genetic polymorphism of the serine rich antigen N-terminal region in Plasmodium falciparum field isolates from Brazil

In this work we investigated the frequency of polymorphism in exon II of the gene encoding most of the amino-terminal region of the serine rich antigen (SERA) in Plasmodium falciparum field samples. The blood samples were colleted from P. falciparum infected individuals in three areas of the Brazilian Amazon. Two fragments have been characterized by polymerase chain reaction: one of 175 bp corresponding to the repeat region with 5 octamer units and one other of 199 bp related to the 6 repeat octamer units of SERA protein. The 199 bp fragment was the predominant one in all the studied areas. The higher frequency of this fragment has not been described before and could be explained by an immunological selection of the plasmodial population in the infected individuals under study. Since repeat motifs in the amino-terminal region of SERA contain epitopes recognized by parasite-inhibitor antibodies, data reported here suggest that the analysis of the polymorphism of P. falciparum isolates in different geographical areas is a preliminary stage before the final drawing of an universal vaccine against malaria can be reached.
