چکیده

YhbO is a member of the DJ-1/ThiJ/Pfp1 superfamily, which includes chaperones, peptidases, and the Parkinson's disease protein DJ-1. A yhbO-disrupted mutant of Escherichia coli is highly sensitive to oxidative, thermal, UV, and pH stresses, and the putative nucleophilic cysteine C104 of YhbO is required for stress resistance. These results suggest that YhbO affects a central process in stress management.

Lipocalin2 Protects Human Embryonic Kidney Cells against Cisplatin–Induced Genotoxicity

Cisplatin is one of the most useful chemotherapeutics which performs its cytotoxic effectvia accumulation of platinum resulting in oxidative stress, and destruction of cell DNA. Thiscould probably cause secondary cancers in healthy tissues. Lipocalin2 (Lcn2) is a protein whichits expression is increased in oxidative stresses. Therefore, the present study was performedto evaluate the protective ...

Nimodipine Protects PC12 Cells against Oxygen-Glucose Deprivation

The protective effect of a L-type calcium channel blocker, nimodipine, on cell injury induced by oxygen-glucose deprivation (OGD) in PC12 cells was investigated. PC12 cells were exposed to in-vitro oxygen-glucose deprivation (30 minutes and 60 minutes respectively) in the presence or absence of nimodipine (10mM/L) in three different time schedules (pre-24h, pre-3h and concurrently). Cellular vi...

Citrus extract protects mouse bone marrow cells against gamma-irradiation

With respect to radiation damage to humans, it is important to seek possible radioprotectants to modify the normal response of biological systems to radiation-induced toxicity or lethality. For this reasons, the search for less-toxic radiation radioprotectants has spurred interest in the development of different compounds. The radioprotective effects of citrus extract were investigated by using...
