FHIT (fragile histidine triad)
Fhit protein is a tumor suppressor with reduced or no expression in many types of cancer. Fhit expression is more frequently lost in cancers of individuals with familial mutations causing deficiency in DNA repair genes such as BRCA1 and BRCA2 and MSH2. In vitro Fhit acts as a hydrolase that cleaves diadenosine triphosphate (Ap3A) to ADP and AMP. The Fhit-Ap3A enzyme-substrate complex appears to...
متن کاملOverexpression of the fragile histidine triad (FHIT) gene in inflammatory bowel disease.
OBJECTIVE FHIT gene encodes human diadenosine triphosphate hydrolase involved in the regulation of cell cycle and nucleotide metabolism and is a candidate tumor suppressor gene. AIM To investigate expression of FHIT gene at the mRNA and protein levels in sporadic inflammatory bowel disease (IBD). MATERIALS AND METHODS FHIT mRNA was quantified by the validated real-time PCR (QPCR) and FHIT p...
متن کاملAbnormal fragile histidine triad (FHIT) expression in advanced cervical carcinoma: a poor prognostic factor.
The FHIT gene is a candidate tumor suppressor gene that has been implicated in the development of cervical carcinoma. We hypothesized that abnormal Fhit expression might be a poor prognostic factor for patients with cervical cancer. The tumors from 59 high-risk patients (stage II-III) were evaluated for abnormal Fhit expression by immunohistochemical staining. Abnormal Fhit expression (absent o...
متن کاملAnalysis of the fragile histidine triad (FHIT) gene in lobular breast cancer.
The fragile histidine triad (FHIT) gene is a candidate tumour suppressor gene in breast and other cancers. We investigated deletions within the FHIT gene in lobular breast cancer and found that 16% of cases showed loss of heterozygosity (LOH) within the gene. We compared LOH within FHIT in lobular and ductal breast tumours and found a significant association between LOH at FHIT and the ductal h...
متن کاملAberrations in the fragile histidine triad (FHIT) gene in idiopathic pulmonary fibrosis.
Idiopathic pulmonary fibrosis (IPF) seems to be closely associated with lung carcinogenesis. To identify the genetic characteristics of precancerous IPF lesions in the peripheral lung, we performed PCR-based microsatellite analysis with DNA extracted from microdissected tissues; fluorescent in situ hybridization (FISH) analysis of the fragile histidine triad (FHIT) gene and immunohistochemical ...
