Promyelocytic leukemia protein is required for gain of function by mutant p53.

مطالعه اثر ضد سرطانی پروبیوتیک‌ها بر میزان پروتئین جهش یافته p53 در رده سلولی K562

Background : Probiotics are defined as different microorganisms that may have positive effects on preventing or treatment of special pathologic conditions. Lactobacillus casei and L. paracasei as probiotics could induce the apoptosis in human cancer cells in vitro. Chronic myeloid leukemia is categorized as a blood cells cancer and the most common type of leukemia. The expression of mutant p53 ...

The Promyelocytic Leukemia Protein, PML, and Its Biological Function

القای آپوپتوز وابسته به p53 در رده‌ی سلولی لوسمی لنفوبلاستیک حاد پیش‌ساز لنفوسیت B (NALM-6) توسط مولکول کوچک RITA

Background and Objective: The use of low-molecular-weight, nonpeptidic molecules that degrade the interaction between the p53 protein and its negative regulator MDM2 (Murine- double minute colon 2) is a new therapeutic strategy for treatment of various types of cancer. One of these agents is RITA (reactivation of p53 and induction of tumor cell apoptosis) which binds to p53 protein and inhibits...

The Effect of 8-Weeks of Low-Intensity Swimming Training on Promyelocytic Leukemia Zinc Finger Protein and Spermatid Transition Nuclear Protein Gene Expression in Azoospermic Rats Model

Aims: One of the causes of infertility in men is the azoospermia disease, which is attributed to the lack of sperm in each sperm. The primary function of spermatogenesis is the maintenance, proliferation, and differentiation of spermatogonial cells. Thus, the present study aimed to investigate the changes in Promyelocytic Leukemia Zinc Finger (PLZF) and spermatid Transition Nuclear Protein (TNP...

Arsenic Trioxide Reactivates Proteasome-Dependent Degradation of Mutant p53 Protein in Cancer Cells in Part via Enhanced Expression of Pirh2 E3 Ligase

The p53 gene is mutated in more than 50% of human tumors. Mutant p53 exerts an oncogenic function and is often highly expressed in cancer cells due to evasion of proteasome-dependent degradation. Thus, reactivating proteasome-dependent degradation of mutant p53 protein is an attractive strategy for cancer management. Previously, we found that arsenic trioxide (ATO), a drug for acute promyelocyt...
