The MDM2 promoter region contains several polymorphisms, some of which have been associated with MDM2 expression, cancer risk and age at cancer onset. del1518 (rs3730485) is an indel polymorphism residing in the MDM2 promoter P1 and is in almost complete linkage disequilibrium with the MDM2 promoter P2 polymorphism SNP309T>G (rs2279744). Cancer risk assessments of del1518 have previously been c...
Nutlin-3a is a small-molecule antagonist of p53/MDM2 that is being explored as a treatment for sarcoma. In this study, we examined the molecular mechanisms underlying the sensitivity of sarcomas to Nutlin-3a. In an ex vivo tissue explant system, we found that TP53 pathway alterations (TP53 status, MDM2/MDM4 genomic amplification/mRNA overexpression, MDM2 SNP309, and TP53 SNP72) did not confer a...
زمینه و هدف: لوسمی حاد میلوئیدی ،یک بیماری ژنتیکی می باشد که در اثر تغییر درمکانیسم های طبیعی سلول های پیش ساز خونی، مثل تکثیر و تمایز، ایجاد می شود. Mouse Double Minute 2 (MDM2)، آنکوپروتئینی با عملکرد E3 یوبی کوئیتین لیگازی است که تنظیم کننده منفی پروتئین P53 می باشد. پلیمورفیسم در جایگاه 309 شناخته شدهترین پلیمورفیسم ژن MDM2 می باشد که جایگزینی نوکلئوتید G به جای نوکلئوتی...
Background & Aims: Leukemia is a type of malignancy of the hematopoietic tissue that accompanies the incomplete development and proliferation of white blood cells. In acute lymphoid leukemia (ALL), many lymphocytes that have not yet completely evolved, are impaired and increasingly found in peripheral blood and bone marrow. MDM2 is a proto-oncogene with E3 ubiquitin ligase activity that acts as...
Introduction: Immunological processes play an important role in recurrent spontaneous abortion(RSA). According to studies, T lymphocytes and natural killer cells(NK cells) are two effective cell groups in RSA. The aim of this study was to study the percentage and absolute number of natural killer(NK) cells in women with RSA of unknown etiology. Methods: A total of 24 women with history of recu...
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...
