Correlation of fragile histidine triad (Fhit) protein structural features with effector interactions and biological functions.
We have previously shown that Fhit tumor suppressor protein interacts with Hsp60 chaperone machinery and ferredoxin reductase (Fdxr) protein. Fhit-effector interactions are associated with a Fhit-dependent increase in Fdxr stability, followed by generation of reactive oxygen species and apoptosis induction under conditions of oxidative stress. To define Fhit structural features that affect inte...
متن کاملFHIT (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 کاملExpression of fragile histidine triad (FHIT) and WW-domain oxidoreductase gene (WWOX) in nasopharyngeal carcinoma.
The aim of the present study was to analyze the expression of FHIT and WWOX in nasopharyngeal carcinoma (NPC) and correlations with clinical pathologic features. mRNA expression of the FHIT and WWOX was assessed by real-time fluorescent relatively quantitative PCR in 61 NPC tissues and 45 non-cancerous nasopharyngeal tissues. As a result, mRNA expression levels of both FHIT and WWOX were signif...
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 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...
