Hsp60 and Hsp10 increase in colon mucosa of Crohn's disease and ulcerative colitis.
2010
The purpose of this work was to determine in colon mucosa of Crohn’s disease (CD) and ulcerative colitis (UC) in relapse: a) the levels of the chaperonins Hsp60 and Hsp10; b) the quantity of inflammatory cells; and c) if the levels of chaperonins parallel those of inflammation cells. Twenty cases of CD and UC and twenty normal controls (NC) were studied using immunohistochemistry, Western blotting and immunofluorescence. Immunohistochemically, Hsp60 and Hsp10 were increased in both inflammatory bowel diseases (IBD) compared to NC. These results were confirmed by Western blotting. Hsp60 and Hsp10 occurred in the cytoplasm of epithelial cells in CD and UC but not in NC. Hsp60 and Hsp10 co-loc…

Hsp60 and human aging: Les liaisons dangereuses
2013
Stressors can cause abnormal intracellular accumulation of Hsp60 and its localization in extramitochondrial sites, secretion, and circulation, with immune system activation. Dysfunction of chaperones associated with their quantitative and qualitative decline with aging (chaperonopathies of aging) characterizes senescence and is a potential causal factor in the physiological deterioration that occurs with it. The role of Hsp60 in aging is not easy to elucidate, because aging is accompanied by pathologies (e.g., cardiovascular and neurodegenerative disorders, osteoporosis, diabetes, cancer, etc.) in which Hsp60 has been implicated but, although those disorders are more frequent in the elderly…
NOVEL ANTAGONISTS FOR AN Hsp60-BASED ANTICANCER CHAPERONOTHERAPY
2012
The Heat shock proteins (Hsps) are nowadays considered the most important cell chaperones, which result overexpressed in response to a number of cell stress stimuli.In tumor cells, when Hsp60 accumulates in the cytosol, without mitochondrial release, it exerts an anti-apoptotic effect, by inhibiting pro-caspase-3 (pC3) activation. In this context, our study aims to elucidate the structural details of the interaction between Hsp60 and pC3 and to design novel antagonists able to specifically block this interaction. The analysis of virtual screening results highlights the 4-(3-chloro-4-fluorophenylamino)- 6-[(1H-imidazol-4-yl-methyl)-3-carbonitrile-quinolines of type 1 and the N-{5-[1H-imidazo…
