The role of p53 family member p63 in oncogenesis is the subject of controversy. Limited research has been done on the clinical implications of p63 expression in diffuse large B-cell lymphoma (DLBCL). In this study, we assessed p63 expression in de novo DLBCL samples (n=795) by immunohistochemistry with a pan-p63-monoclonal antibody and correlated it with other clinicopathologic factors and clin...
The p63 transcription factor has a pivotal role in epithelial morphogenesis. Multiple transcripts of the TP63 gene are generated because of alternative promoter usage and splicing. DeltaNp63alpha is the predominant isoform of p63 observed during epithelial morphogenesis and in human cancers. Loss of DeltaNp63alpha expression has been shown to promote invasiveness in a subset of human cancer cel...
PURPOSE To characterize human limbal epithelial cells based on the expression levels of nuclear protein p63 and the nucleus-to-cytoplasm (N/C) ratio. METHODS Limbal, peripheral, and central corneal epithelia were separated from the stroma by Dispase II and subsequently were treated with trypsin to obtain single-cell suspensions. Cytospin smears of the cell suspensions were double immunostaine...
The p63 gene encodes a master regulator of epidermal commitment, development, and differentiation. Heterozygous mutations in the C-terminal domain of the p63 gene can cause ankyloblepharon-ectodermal defects-cleft lip/palate (AEC) syndrome, a life-threatening disorder characterized by skin fragility and severe, long-lasting skin erosions. Despite deep knowledge of p63 functions, little is known...
p63 is essential for normal epithelial development and is overexpressed in the vast majority of squamous cell carcinomas (SCC). Recent work had shown that DeltaNp63alpha is essential for survival of SCC cells, raising the possibility that the p63 pathway may be an attractive therapeutic target in these tumors. Nevertheless, it is unknown whether a therapeutic window exists for inhibiting p63 in...
PURPOSE The p63 gene, located on chromosome 3q27-28, is a member of the p53 gene family. The product encoded by the p63 gene has been reported to be essential for normal development. EXPERIMENTAL DESIGN In this study, we examined the expression pattern of p63 in human normal and tumor tissues by immunohistochemistry using a monoclonal antibody (clone 4A4) that recognizes all p63 splice varian...
زمینه: سرطان غیرملانومایی پوست شامل کارسینوم سلول بازال و کارسینوم سلول سنگفرشی بوده که شایعترین بدخیمیهای انسان میباشند. هدف این مطالعه بررسی میزان بروز ژن P63 در سرطانهای معمول پوست و ضایعات غیرتومورال پوست ومقایسه این دو میباشد. مواد و روشها: در این مطالعه توصیفی- مقطعی، نمونهگیری از بلوکهای بایگانی شده سالهای 1389 و 1390 بیماران در بیمارستان شهید محمدی بندر عباس انجام شد. بدین ترتی...
The p53 family activates many of the same genes in response to DNA damage. Because p63 and p73 have structural differences from p53 and play distinct biological functions in development and metastasis, it is likely that they activate a unique transcriptional network. Therefore, we performed a genome-wide analysis using cells lacking the p53 family members after treatment with DNA damage. We ide...
p63 is a transcriptional factor belonging to p53 family of genes. Beside the role in cancer, partially shared with p53 and the other member p73, p63 also plays exclusive roles in development and homeostasis of ectodermal/epidermal-related organs. Here we show that p63 transcriptionally controls the expression of the matrix metallopeptidase 13 (MMP13). p63 binds a p53-like responsive element in ...
BACKGROUND p63 is a member of the p53 family that has been implicated in maintenance of epithelial stem cell compartments. Previous studies demonstrated that p63 is downregulated in muscle-invasive bladder cancers, but the relationship between p63 expression and survival is not clear. METHODOLOGY/PRINCIPAL FINDINGS We used real-time PCR to characterize p63 expression and several genes implica...
