Stabilization of p53 is involved in quercetin-induced cell cycle arrest and apoptosis in HepG2 cells.
There is evidence for defects in the mechanisms that allow the activation of p53 in many of the cancers that retain wild-type p53. Reactivation of p53 has been suggested to be an effective strategy for cancer therapy in wild-type p53-retained tumor cells. In the present study, we attempted to reactivate p53 in HepG2 retaining wild-type p53 by quercetin, an ubiquitous bioactive plant flavonoid. ...
متن کاملEnhanced DNA damage-induced p53 peptide phosphorylation and cell-cycle arrest in Sjögren's syndrome cells.
BACKGROUND Cells from primary Sjögren's syndrome (SS) patients have been reported to show alterations in DNA repair and p53 expression. The DNA-dependent protein kinase (DNA-PK) autoantigen may be involved in both of these alterations in relation to cellular DNA damage responses. We conducted this study of cell-cycle kinetics and p53 to find additional evidence for an abnormal stress response r...
متن کاملp53 is dispensable for UV-induced cell cycle arrest at late G(1) in mammalian cells.
Genotoxic agents, including gamma-rays and UV light, induce transient arrest at different phases of the cell cycle. These arrests are required for efficient repair of DNA lesions, and employ several factors, including the product of the tumor suppressor gene p53 that plays a central role in the cellular response to DNA damage. p53 protein has a major function in the gamma-ray-induced cell cycle...
متن کامل[6]-Gingerol Induces Cell Cycle Arrest and Cell Death of Mutant p53-expressing Pancreatic Cancer Cells
[6]-Gingerol, a major phenolic compound derived from ginger, has anti-bacterial, anti-inflammatory and anti-tumor activities. While several molecular mechanisms have been described to underlie its effects on cells in vitro and in vivo, the underlying mechanisms by which [6]-gingerol exerts anti-tumorigenic effects are largely unknown. The purpose of this study was to investigate the action of [...
متن کاملN-Terminal Domain of Fragile Histidine Triad Exerts Potent Cytotoxic Effect in HT1080 Cells
Fragile histidine triad (FHIT) serves a critical function as a tumor suppressor that inhibits p53 degradation by mouse double minute 2 (MDM2). The functional domains of FHIT involved in tumor inhibition was interpreted. In-silico screening data were employed to construct truncated forms of FHIT to assess their cytotoxic effects on the HT1080 cell line. Full FHIT expression was confirmed by west...
