Research in autophagy continues to accelerate,(1) and as a result many new scientists are entering the field. Accordingly, it is important to establish a standard set of criteria for monitoring macroautophagy in different organisms. Recent reviews have described the range of assays that have been used for this purpose.(2,3) There are many useful and(More)
Susceptibility to Crohn's disease, a complex inflammatory disease, is influenced by common variants at many loci. The common exonic synonymous SNP (c.313C>T) in IRGM, found in strong linkage disequilibrium with a deletion polymorphism, has been classified as non-causative because of the absence of an alteration in the IRGM protein sequence or splice sites.(More)
Connexins, the constitutive proteins of gap junctions, are considered to be tumour suppressive agents and are often impaired in the tumourigenic processes. In the present study, the expression of connexin 43 (Cx43), which is involved in the control of spermatogenesis through Sertoli/germ cell coupling, has been investigated in human testicular seminoma(More)
Degradation of signaling proteins is one of the most powerful tumor-suppressive mechanisms by which a cell can control its own growth. Here, we identify RHOA as the molecular target by which autophagy maintains genomic stability. Specifically, inhibition of autophagosome degradation by the loss of the v-ATPase a3 (TCIRG1) subunit is sufficient to induce(More)
The aim of this study was to characterize the role of CFTR during Cd(2+)-induced apoptosis. For this purpose primary cultures and cell lines originated from proximal tubules (PCT) of wild-type cftr(+/+) and cftr(-/-) mice were used. In cftr(+/+) cells, the application of Cd(2+) (5 microM) stimulated within 8 min an ERK1/2-activated CFTR-like Cl(-)(More)
Interest in biomarkers in the field of thoracic oncology is focused on the search for new robust tests for diagnosis (in particular for screening), prognosis and theragnosis. These biomarkers can be detected in tissues and/or cells, but also in biological fluids, mainly the blood. In this context, there is growing interest in the detection of circulating(More)
Use of the nonpathogenic yeast Saccharomyces boulardii in the treatment of infectious diarrhea has attracted growing interest. The present study designed to investigate the effect of this yeast on enteropathogenic Escherichia coli (EPEC)-associated disease demonstrates that S. boulardii abrogated the alterations induced by an EPEC strain on transepithelial(More)
Connexins form gap junction channels that allow intercellular communication between neighboring cells. Compelling evidence has revealed that Cx are tumor-suppressor genes and reduced Cx expression has been related with uncontrolled cell growth in tumors and transformed cells. In the present study, we addressed Cx transcriptional and posttranscriptional(More)
Susceptibility to Crohn disease (CD), an inflammatory bowel disease, is influenced by common variants at many loci like the exonic synonymous IRGM SNP (rs10065172, NM_001145805.1, c.313C>T). We recently showed that miR-196 is overexpressed in the inflammatory intestinal epithelia of individuals with CD and downregulates the IRGM protective (c.313C) but not(More)
Hirschsprung's disease (HSCR), a frequent developmental defect of the enteric nervous system is due to loss-of-function mutations of RET, a receptor tyrosine kinase essential for the mediation of glial cell-derived neurotrophic factor (GDNF)-induced cell survival. Instead, gain-of-function Cys mutations (e.g., Cys(609), Cys(620), and Cys(634)) of the same(More)
