After 24 h post exposure, selected biological endpoints were evaluated, such as cell viability, morphology, barrier integrity, induction of (pro- inflammation and oxidative stress reactions and compro- inflammationference mandrial carboxidative
DJ-1 is a ubiquitously expressed protein known to regulate the cellular response to oxidative stress by various mechanisms, including regulation of gene expression and mitochondrial integrity, induction of survival pathways and protein refolding.
Results of Experiment 1 showed no significant positive effect of increasing the concentration of egg yolk above 10% on post-thaw motility, membrane integrity, or induction of sperm capacitation-like changes.
Recent research suggests that the topical antimicrobial zinc pyrithione is a potent heat shock response inducer that may impair genomic integrity with induction of PARP-dependent energy crisis in cultured human keratinocytes and melanocytes.
Sperm acrosome integrity and induction of apoptosis were assessed using the acrosomal content marker PSA-FITC and annexin V kit, respectively.
BRCA1 is a 1863 amino-acid protein, particularly expressed by actively dividing cells, important for regulation of cell proliferation, DNA repair, the maintenance of genomic integrity and induction of apoptosis in damaged cells (Venkitaraman, 2002).
Considering that the p53 gene is mutated in approximately 50% of all tumours, its role in the control of cell cycle progression, maintenance of DNA integrity and induction of apoptosis is well documented (Zhan et al, 1993; Yonish-Rouach et al, 1995).
Therefore, the regulation of T cells by endogenous TGFβ is important for the maintenance of joint integrity after arthritis induction.
These results demonstrate that endogenous TGFβ acts on T cells to maintain joint integrity after the induction of arthritis and during the healing phase of disease.
DNA integrity and enzyme induction elucidate the physiologic status and might be indicative for ambient impairment within restricted areas, and not necessarily related to the presence of anthropogenic or xenobiotic substances.
Prior to studies with Tnv-6, the integrity of p53 induction in these cells was confirmed in 24 h cultures with the genotoxic drug fludarabine (3 m M, Sigma, Dorset, UK).
