The p53 tumor suppressor directs the cellular response to many mechanistically distinct DNA-damaging agents and is selected against during the pathogenesis of therapy-related acute myeloid leukemia (t-AML). We hypothesized that constitutional genetic variation in the p53 pathway would affect t-AML risk. Therefore, we tested associations between patients with t-AML (n = 171) and 2 common functio...
A. Storey et al. [Nature (Lond.), 393: 229-234, 1998)] reported a 7-fold increased risk of cervical cancer associated with having an Arg/Arg polymorphism at codon 72 of p53 compared with the Pro/Arg heterozygotes (odds ratio, 7.4; 95% confidence interval, 2.1-29.4). Complementary in vitro studies suggested that the HPV E6 oncoprotein more readily targets the arginine form, as opposed to the pro...
The p53 protein and its regulator MDM2 is central to tumorigenesis by directing cells to undergo cell cycle arrest and/or apoptosis in response to DNA damage or other stress signals. The genes encoding these proteins contain nucleotide variation (p53 codon 72, MDM2 SNP309) that influences cellular response. We examined the p53 codon 72 and MDM2 SNP309 to determine their implication with age of ...
The functional outcome after stroke is unpredictable; it is not accurately predicted by clinical pictures upon hospital admission. The presence of apoptotic neurons in the ischemic penumbra and perihematoma area may account for poor prognosis, but whether the highly variable stroke outcome reflects differences in genetic susceptibility to apoptosis is elusive. The p53 tumor suppressor protein, ...
OBJECTIVE Type 2 diabetes is a common complex disorder with environmental and genetic components. We used a candidate gene-based approach to identify single nucleotide polymorphism (SNP) variants in 222 candidate genes that influence susceptibility to type 2 diabetes. RESEARCH DESIGN AND METHODS In a case-control study of 1,161 type 2 diabetic subjects and 1,174 control Finns who are normal g...
T he cause of in-stent luminal narrowing has been primarily considered to be neointimal hyperplasia that is caused by proliferating vascular smooth muscle cells (VSMC). It has been recently reported that local drug delivery systems produce good results for the inhibition of VSMC proliferation. The potential of suppressive agents in the treatment of in-stent luminal narrowing arises from basic s...
BACKGROUND It is believed that Human Papillomavirus (HPV) and Human Immunodeficiency Virus coinfection contributes to increase the risk for cervical intraepithelial injuries. Several factors may contribute to cervical cancer (CC) development, including genetic variants such as TP53 and MDM2 gene polymorphisms. MATERIALS AND METHODS A hundred HIV-infected women were examined for HPV detection ...
The P53 tumor suppressor pathway plays an important role in cancer development. The auto-regulatory feedback mechanism of the P53 and MDM2 expression is critical in keeping proper tumor suppressor function of this pathway. This study examined the effect of P53 Arg72Pro variants on transactivation of polymorphic MDM2 promoter (T309G) and their associations with risk of developing gastric cardia ...
