سرطان پوست یکی از شایع ترین انواع سرطان ها در سراسر جهان می باشد که بیش از 50% از تمام سرطان ها را شامل می شود. سه نوع اصلی سرطان پوست وجود دارد. فراوان ترین فرم آن، کارسینومای سلول پایه می باشد (bcc)، کارسینومای سلول پوششی (scc) و ملانوما (cmm) انواع دیگر آن می باشند. پرتو فرابنفش خورشید که منجر به آسیب dna می شود، مهم ترین فاکتور خطر برای تمام انواع سرطان پوست است. ژن tp53 یکی از ژن های کلیدی...
BACKGROUND Non-melanoma skin cancers are one of the most common human malignancies accounting for 2-3% of tumors in the US and represent a significant health burden. Epidemiology studies have implicated Tp53 mutations triggered by UV exposure, and human papilloma virus (HPV) infection to be significant causes of non-melanoma skin cancer. However, the relationship between Tp53 and cutaneous HPV ...
Objectives: The bioactive phytocompounds present in Zingiber officinale were assessed for their tumor-suppressing activity against TP-53 BP1 linked to hepatocellular carcinoma. Methods: study investigates the interaction of phytochemicals from Ginger (Zingiber officinale) with tumor protein TP53. Drug likeness chosen ligand was evaluated using SWISS ADME. Autodock tools used investigate interac...
Autophagy is an evolutionarily conserved lysosomal degradation pathway that plays an essential role in enabling eukaryotic organisms to adapt to nutrient deprivation and other forms of environmental stress. In metazoan organisms, autophagy is essential for differentiation and normal development; however, whether the autophagy pathway promotes or inhibits tumorigenesis is controversial, and the ...
Balanced deoxyribonucleotides pools are essential for cell survival and genome stability. Ribonucleotide reductase is the rate-limiting enzyme for the production of deoxyribonucleotides. We report here that p53 suppresses ribonucleotide reductase subunit 1 (RRM1) and 2 (RRM2) via inhibiting mammalian target of rapamycin complex 1 (mTORC1). In vitro, cancer cell lines and mouse embryonic fibrobl...
This study aimed to identify the key differentially expressed genes (DEGs) following ischemic stroke (IS).The GSE22255 microarray dataset, which contains samples from peripheral blood mononuclear cells of 20 IS patients and 20 sex- and age-matched controls, was downloaded from the Gene Expression Omnibus. After data pre-processing, DEGs were identified using the Linear Models for Microarray Dat...
TP53 is the mostly commonly mutated gene in many cancers and the P53 tumor suppressor protein is involved in multiple cellular processes, including transcription, DNA repair, genomic stability, senescence, cell cycle control and apoptosis. A common single nucleotide polymorphism located within the proline rich region of TP53 gene at codon 72 in exon 4 encodes either proline or arginine. TP53 Ar...
PICT1 is a key regulator of the MDM2-TP53 pathway. High mRNA expression levels of PICT1 are associated with poor prognosis in several cancers with wild-type TP53. In this study, we identified the PICT1 protein expression profile in non-small cell lung cancer (NSCLC) with wild-type TP53 in the nucleolus and cytoplasm, and revealed the relationship between PICT1 expression and patient clinicopath...
Several groups have studied the molecular pathology of inherited breast cancer. By combining several such studies, we show in this study that somatic TP53 abnormalities are more common in breast cancer associated with BRCA1 or BRCA2 germ-line mutations than in sporadic breast cancers (odds ratio, 2.8; P = 0.0003). Then, we compared the spectrum of TP53 mutations for breast cancers in the IARC T...
