سابقه و هدف: تعداد کمی از نمونه هایی که به عنوان لیکن پلان و ضایعات لیکنوئید دهانی شناخته شده اند، می توانند به بدخیمی تبدیل شوند. تشخیص هیستولوژیکی همیشه در افتراق لیکن پلان از ضایعات لیکنوئید دهانی به تشخیص صحیح نمی رسد. لذا این مطالعه به منظور بررسی ایمونوهیستوشیمیایی بیان نشانگرهای P53 و P63 در لیکن پلان و ضایعات لیکنوئید دهانی با توجه به اتیولوژی متفاوت، رفتار بالینی و تمایل متفاوت به تغیی...
p63, a transcription factor and p53 family protein, plays a crucial role in tumor suppression and development of various epithelial tissues. While p63 expression is controlled mostly by post-translational modifications, recent studies indicate that transcriptional and posttranscriptional regulations are essential for proper p63 expression. Here, we investigated the regulation of p63 expression ...
BACKGROUND AND PURPOSE Giant cell tumor of bone (GCT) is sometimes difficult to distinguish from other giant-cell-rich tumors such as chondroblastoma (CHB) and aneurysmal bone cyst (ABC). The usefulness of p63 as a diagnostic marker for GCT is controversial. While there have been no reports about p63 as a prognostic marker for local recurrence, various p63-positive rates in GCT have been report...
p63, a member of p53 family, has a significant role in the development and maintenance of stratified epithelia. However, a persistent dispute remained over the last decade concerning the interpretation of the severe failure of p63-null embryos to develop stratified epithelia. In this study, by investigating both p63-deficient strains, we demonstrated that p63-deficient epithelia failed to devel...
p63 belongs to a family of transcription factors, which, while demonstrating striking conservation of functional domains, regulate distinct biological functions. Its principal role is in the regulation of epithelial commitment, differentiation and maintenance programs, during embryogenesis and in adult tissues. The p63 gene has a complex transcriptional pattern, producing two subclasses of N-te...
p63, which has recently been identified as a member of the p53 gene family, plays many important roles in human tissue functions. We examined p63 expression patterns in esophageal Barrett's adenocarcinoma, including early-stage cancers, as well as its clinicopathological significance. Immunoreactivity for p63 was detected in 45.8% (11/24) of the adenocarcinomas; all cases were focally positive....
p63 is a type II integral membrane protein that has previously been suggested to be a resident protein of a membrane network interposed between the ER and the Golgi apparatus. In the present study, we have produced a polyclonal antibody against the purified human p63 protein to reassess the subcellular distribution of p63 by confocal immunofluorescence, immunoelectron microscopy, and cell fract...
p63, a member of the p53 family of transcription factors, plays an important role in epithelial development, regulating both cell cycle and apoptosis. Even though p63 activity is regulated mainly at the posttranslational level, the control of p63 protein stability is far from being fully understood. Here, we show that the Hect (homologous to the E6-associated protein C terminus)-containing Nedd...
the p63 gene, a member of the p53 gene family, is expressed into at least six protein isoforms.the transcription factor p63 is a homologue of the tumor suppressor p53. unlike p53, which is dispensable for normal development, p63 is critical for the development of stratified epithelial tissues such as epidermis, breast, and prostate. p63, , is transcribed from two different promoters giving rise...
BACKGROUND P63 immunostaining has been considered as potential prognostic factor in laryngeal cancer. Considering that P63 is mainly nuclear stain, a possible correlation between the texture of P63-stained nuclei and the tumor's grade could be of value to diagnosis, since this may be related to biologic information imprinted as texture on P63 expressed nuclei. OBJECTIVE To investigate the ass...
