Expression of an IFN-inducible cellular senescence gene, IFI16, is up-regulated by p53.

IFN-inducible IFI16 protein (encoded by IFI16 gene at 1q23.1) is the human member of the IFN-inducible structurally related p200 family proteins. Increased expression of the IFI16 protein, a positive modulator of p53-mediated transcription, in normal old human diploid fibroblasts (HDF) is associated with cellular senescence-mediated cell growth arrest. However, the underlying mechanisms that co...

YPEL3, a p53-regulated gene that induces cellular senescence.

Cellular senescence, the limited ability of cultured normal cells to divide, can result from cellular damage triggered through oncogene activation (premature senescence) or the loss of telomeres following successive rounds of DNA replication (replicative senescence). Although both processes require a functional p53 signaling pathway, relevant downstream p53 targets have been difficult to identi...

Sin3B expression is required for cellular senescence and is up-regulated upon oncogenic stress.

Serial passage of primary mammalian cells or strong mitogenic signals induce a permanent exit from the cell cycle called senescence. A characteristic of senescent cells is the heterochromatinization of loci encoding pro-proliferative genes, leading to their transcriptional silencing. Senescence is thought to represent a defense mechanism against uncontrolled proliferation and cancer. Consequent...

RRM2B Suppresses Activation of the Oxidative Stress Pathway and is Up-regulated by P53 During Senescence

RRM2B is the DNA damage-inducible small subunit of ribonucleotide reductase, the rate-limiting enzyme in de novo deoxyribonucleoside triphosphate synthesis. Although RRM2B is implicated in DNA repair and the maintenance of mitochondrial DNA content, the regulation and function of RRM2B in senescence have not been previously established. Here, we show that RRM2B is highly induced in a p53-depend...

Vascular Endothelial Growth Factor Production is Regulated by Gene Polymorphisms

Background: Vascular endothelial growth factor (VEGF) has a key role in angiogene-sis and in transplantation. The level of VEGF is related to the differences in the DNA sequence of its promoter region. Objectives: In this study, the association between the combination of VEGF –1154 G and –2578 C alleles and VEGF production by LPS-stimulated PBMCs was investigated. In addition; the relationship ...
