Full textSchizophrenia is a psychotic disorder of the young adult, which is a major proplem for public health because of its prevalence of 1% in the general population. Because schizophrenia presents a clinical heterogeneity and a multifactorial determinism, it is difficult to identify a risk factor for this disease. The comorbidity between schizophrenia and the 22q11 deletion syndrome (22q11DS) suggested a putative rearrangement of the 22q11 region in schizophrenic patients. Screening for genomic rearrangements of 23 genes within or at the boundaries of the deletion 22q11 in 63 unrelated schizophrenic patients DSMIII and 68 controls, using QMPSF, led us to identify, in a family including two schizophrenic subjects, a selective heterozygous deletion of the entire PRODH gene. PRODH gene encodes a proline dehydrogenase enzyme, which is involved in the first step of the conversion of proline to glutamate. The measure of prolinemia in the two patients revealed a moderate elevated plasma proline level. We then detected, by sequencing, in a subset of schizophrenic patients, without rearrangements, several heterozygous PRODH missense mutations, which were also associated with increased plasma proline levels. Interestingly, we subsequently found the same PRODH deletion or missense mutations, at the homozygous state, in children suffering from a severe form of type I hyperprolinemia associated with neurological manifestations (mental retardation and seizure). To determine the involvement of hyperprolinemia disorders in psychotic disease including in the schizophrenic spectrum, we conducted a case-control study (including 320 patients with 114 controls), based on DSMIIIR criteria to distinguish schizophrenic patients, patients with a schizoaffective disorder and patients with a bipolar disorder. We found that hyperprolinemia was a risk factor for schizoaffective disorder and that five rare PRODH alterations were associated with hyperprolinemia. Altogether these results show that the severe form of type I hyperprolinemia results into mental retardation whereas the moderate form may constitute a risk factor for certain forms of psychosis

Full textLung adenocarcinomas (LUAD) are a subset of non-small-cell lung cancers, comprising approximately 85% of diagnosed lung cancer cases. The 5-year survival rate varies depending on the tumor stage, with approximately 68% survival for early-stage cases and nearly 0% survival for the most advanced stages. These cancers exhibit a range of mutational characteristics that may account for the varying degrees of severity. Liver Kinase B, abbreviated as LKB1, is found to be mutated in 8 to 21% of LUAD cases. While it is not the initiating factor in lung tumorigenesis, the loss of this protein significantly worsens the prognosis for affected patients.LKB1 is a serine-threonine kinase encoded by the STK11 gene, and it plays a pivotal role in the development and maintenance of various organs. Our team has uncovered essential metabolic regulations governed by LKB1 in distinct lineages of a specific embryonic stem cell population known as neural crest cells (NCCs). During my PhD, I contributed to investigating the significance of LKB1 in the establishment of the enteric nervous system—a complex network of ganglia responsible for regulating digestive motility and entirely derived from NCCs. Our research demonstrated the critical role of LKB1 in the differentiation of enteric neurons and the maintenance of enteric glial cells by limiting oxidative stress and modulating the activity of the p53 transcription factor.In this context, my doctoral research also delved into whether the metabolic regulations governed by LKB1 during NCC formation could also contribute to LKB1's tumor-suppressive activity. By conducting in silico analysis of transcriptomic data from LUAD patients with LKB1 mutations (in conjunction with oncogenic KRAS mutations), I have demonstrated that the loss of LKB1 function is linked to significant alterations in amino acid metabolism. Specifically, the expression of numerous enzymes involved in alanine metabolism is increased in the absence of LKB1 in lung adenocarcinomas. This increase aligns with data obtained from lung tumor cell cultures, which indicate higher levels of alanine in the absence of LKB1. Furthermore, LKB1 mutations are associated with dysregulation of metabolites and enzymes related to redox homeostasis, global epigenetic changes, as well as the stabilization of p53 and alterations in the expression of its target genes.Hence, my findings underscore the shared regulatory mechanisms between LKB1's developmental role in NCCs and its tumor-suppressive function in lung adenocarcinomas. These analyses, conducted in LUAD patients, further underscore the potential significance of LKB1 signaling in human developmental syndromes, even though mutations in this pathway are not currently associated with neurocristopathies—pathologies stemming from NCC malformations. Additionally, the identification of other dysregulations in LUADs, such as the regulation of oxidative stress via the NRF2-KEAP1 pathway and the deregulation of the transcription factor and chromatin regulator BRG1, reciprocally inspire a deeper understanding of LKB1's developmental functions. Collectively, these findings pave the way for exploring novel therapeutic strategies for conditions linked to diminished LKB1 signaling

"Supplémentation nutritionnelle en arginine chez des sujets sains présentant des facteurs de risque liés au syndrome métabolique : métabolisme de l'arginine alimentaire et impact sur la fonction endothéliale." Thesis, Université Paris-Saclay (ComUE), 2016. http://www.theses.fr/2016SACLA001/document.
Full textVascular endothelial dysfunction, the hallmark of early atherosclerosis, results from an impairment of the synthesis and/or bioavailability of nitric oxide (NO), the precursor of which is arginine. Endothelial dysfunction is also known to be induced transiently by a high-fat meal. In subject with cardiometabolic risk factors, oral arginine supplementation has a beneficial effect on NO-related physiological functions. However, no data relates the availability of arginine to the synthesis of NO in normal or cardiometabolic risk condition. In addition, few studies only have investigated the effect of arginine supplementation in a nutritional context (low dose and slow release) in subjects with cardiometabolic risk factors. This work aims to evaluate the effect of a nutritional arginine supplementation, on the arginine metabolism and endothelial function in healthy subjects with cardiometabolic risk factors. In a first clinical study, we have compared the bioavailability of oral arginine and its utilization for NO synthesis, as a function of the presence of cardiometabolic risk factors, and as a function of the form of release (immediate release, IR, as free arginine, or sustained release, SR, which mimics the slow release of dietary arginine). Then, in a second clinical study, we studied the effect of SR-arginine supplementation on fasting endothelial function and its postprandial alteration in healthy subjects with cardiometabolic factors. A further aim was to investigate whether this effect may vary according to the baseline arginine status of subjects. This thesis work has demonstrated a higher utilization of oral arginine for NO synthesis in subjects with cardiometabolic risk factors, and a higher utilization with the SR form, particularly in these subjects at risk. As to the second study, it showed that the SRarginine supplementation effects largely varied with baseline fasting arginine concentration of subjects with cardiometabolic risk factors. In subjects with a relatively lower baseline arginine concentration, SR-arginine attenuated the decrease in postprandial endothelial function and led to a significantly higher endothelial function at the end of the postprandial period
