Tài liệu Báo cáo khoa học: Down-regulation of heme oxygenase-2 is associated with the increased expression of heme oxygenase-1 in human cell lines docx

... The intracellular concentration of heme is maintained by the rate of its synthesis and degrada- tion [1]. Many enzymes and their regulators are responsible for heme synthesis [1,2]. On the other hand, ... in the accumulation of heme in the hemin- treated HepG2 cells. Taken together with the siHO-2- mediated induction of HO-1 expression, these results suggest that HO-2 rather...

... melanoma cell line, but in contrast to what was observed in RAW 264.7 cells, the mutant was able to efﬁciently kill these cells. These data are consistent with the notion that induction of pyroptosis ... suggests that different types of cells are killed by LF as a result of the cleavage of distinct substrates. To summarize, we have isolated an LF mutant that is impaired in its abi...

Tài liệu Báo cáo khoa học: Accessibility changes within diphtheria toxin T domain when in the functional molten globule state, as determined using hydrogen⁄deuterium exchange measurements pdf

... In the case of the T domain, the MG state corresponds to the functional state, which initi- ates the translocation of the catalytic domain. Here, the data allowed identiﬁcation of the core of the ... structure, TH5 is partly accessible at the surface of the T domain. We propose that its high protection is caused by the formation of dimers. Within the molten...
