The p53 family of transcription factors is made up of p53, p63 and p73, which share significant structural homology. In particular, transcriptional complexity and the expression of multiple protein isoforms are an emergent trait of all family members. p63 is the evolutionarily eldest member of the p53 family and the various isoforms have critical roles in the development of stratifying epitheli...

Objective. Creatine kinase (CK), cathepsin D (CTSD), Ki67, and tumour protein 63 (p63) have been proven to participate in the growth of some cancers. However, available literature suggested paucity data on their involvement oesophageal squamous-cell carcinoma (ESCC) development. Methods. We ascertained presence CK, CTSD, p63 expressions ESCC demonstrate association between differentiation above...

Background: Using immunohistochemical stains to target specific breast cancer markers has become indispensable for evaluation of small diagnostic tissue specimens, and therefore novel marker cocktails for specific breast cancers are required. This study was conducted to assess the immunoexpression of P63 and SOX2 in triple negative breast cancer (TNBC), and to evaluate the predictive diagnostic...

Squamous cell carcinoma (SCC) is a treatment-refractory subtype of human cancer arising from stratified epithelium of the skin, lung, esophagus, oropharynx, and other tissues. A unifying feature of SCC is high-level expression of the p53-related protein p63 (TP63) in 80% of cases. The major protein isoform of p63 expressed in SCC is ΔNp63α, an N-terminally truncated form which functions as a ke...

P63 is basically a stem cell marker. It belongs to p53 protein family which comprises of transcription factors p53, p63, p73. P63 also possesses two isoforms which are interestingly with opposing characters. Its complexity remains unrevealed with helps in maintenance of genetic stability of germ cells, mechanisms of p63 behaves both monogenic as well as tumor suppressor of its various isoforms....

Heterozygous germline mutations in p63, a transcription factor of the p53 family, result in abnormal morphogenesis of the skin and its associated structures, including hair follicles and teeth. In mice lacking p63, all ectodermal organs fail to develop, and stratification of the epidermis is absent. We show that the ectodermal placodes that mark early tooth and hair follicle morphogenesis do no...

A carboxy-terminal peptide of the poliovirus replicase protein (p63) was chemically synthesized, coupled to bovine serum albumin carrier, and injected into rabbits. The resulting antisera reacted with six virus-specific proteins from HeLa cells infected with poliovirus: NCVP 0b, NCVP 1b, NCVP 2, a protein of about 60,000 daltons, p63, and NCVP 6b. The identity of the 60,000-dalton protein is no...

background and objective: histological grading has prognostic and therapeutic implications in meningioma. however, histological criteria are sometimes not fulfilled to predict the biological behavior of meningiomas. p63 gene is a novel p53 family member, known as tumor suppressor factor, with multiple isoforms and shows high expression in many normal and neoplastic human tissues. in this study,...
