The gene expression level of p53 and p21 in mouse brain exposed to radiofrequency field
Background: Widespread and growing sources of electromagnetic radiation raised concerns attributed to the potential adverse health risk of radiofrequency fields. Given the functional importance of the hippocampus, this study aimed to investigate the effects of electromagnetic waves radiated by mobile jammer on hippocampal expression of p21 and p53 genes as regulators of cellular apoptosis...
متن کاملEffect of citric acid on p53 and p21 genes expression of the human colorectal Adenocarcinoma cell line
Background & Aim: Despite the advances in treatment of colorectal adenocarcinoma patients continue to have low survival. Citric acid is considered as a physiological inhibitor of enzymes involved in glycolysis pathway to remove cancer cells. The p53 and p21 gene products are involved in cell removal due to their pro-apoptotic properties. In this study, the effect of citric acid on p53 and p21 g...
متن کاملUltraviolet Radiation Induces p16 Expression in Human Skin
The loss of the tumor suppressor gene product p16 in melanoma is well documented, although the normal physiological function of p16 in skin melanocytes is unknown. In this report, we demonstrate that when human skin was irradiated with suberythemal doses of UV radiation, levels of p16 were dramatically increased by 16 h postirradiation, peaking at 24 h, and declining by 72 h. p16 was expressed ...
متن کاملGADD34 induces p21 expression and cellular senescence.
We previously identified GADD34 (growth arrest and DNA damage protein 34) by screening for genes involved in oncogenic-transformation and/or cellular senescence in Ras-transformed rat F2408 fibroblasts (7EJ-Ras), which exhibit anchorage-independent growth and do not senesce. In the current study, we found that transduction of 7EJ-Ras cells with a retroviral vector expressing GADD34 suppressed t...
متن کاملPrognostic Significance of p21 and p53 Expression in Gastric Cancer
BACKGROUND Cyclin-dependent kinase inhibitors (CDKI), including p21, p27 and p57 of the KIP family, are negative regulators of cell cycle progression and potentially act as tumor suppressors. The expression of p21 is induced by tumor suppressor gene p53. Mutations of p53 are common and found in various human cancers. Thus, the function of p21 as a tumor suppressor may be not retained after p53 ...
