Ptch1 tumor suppressor
PTCH1 is a member of the patched gene family and is the receptor for sonic hedgehog, a secreted molecule implicated in the formation of embryonic structures and in tumorigenesis. This gene functions as a tumor suppressor. The PTCH1 gene product, is a transmembrane protein that suppresses the release of another protein called smoothened, and when sonic hedgehog binds PTCH1, smoothened is released and signals cell proliferation.

Webafter genetic diagnosis. PTCH1 is a tumor suppressor gene is the most common mutated in Gorlin-Goltz syndrome. A frameshift mutation is the most frequently, followed by nonsense mutation; the result is a premature termination of PTCH1 translation. PTCH1 is placed on the long arm of chromosome 9 (9q22.32) and it is made of 23 exons [3-4]. Webtumor suppressor function of Hic1 might be revealed in the Ptch1 knockout mouse model. Here, we demonstrate a critical role of Hic1 as a neu-ronal tumor suppressor in the setting of heterozygous mutations in Ptch1. Hic1 heterozygosity dramatically increases the incidence of medulloblastoma on the Ptch1 heterozygous background. These tumors are ...

WebApr 14, 2004 · The PTCH1 tumor suppressor gene encodes a receptor for secreted hedgehog (HH) ligands and is important for proper proliferation, differentiation and patterning in almost every tissue and organ during embryogenesis. The PTCH1 protein works as a negative regulator of the HH-signaling pathway by repressing downstream …
WebLindstrom et al. (2006) analyzed the distribution of mutations in the PTCH1 gene underlying the nevoid basal cell carcinoma syndrome and in many different sporadic tumors in which PTCH1 appears to act as a tumor suppressor gene. Sporadic medulloblastomas were among the more frequent of the latter group. WebIntroduction. Nevoid basal cell carcinoma syndrome (NBCCS), or Gorlin syndrome, is a rare hereditary disease characterized by the development of multiple cutaneous basal cell carcinomas (BCCs) from a young age. 1 Loss-of-function germline mutations in the hedgehog-related patched 1 (PTCH1) tumor suppressor gene are the most common …
