Overexpression 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...

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...

Expression of the Fragile Histidine Triad Gene in Laryngeal Carcinoma

The aim of this study was to investigate Fragile Histidine Triad Gene (FHIT) expression in laryngeal squamous cell carcinoma. The paraffin embedded tissue blocks of 64 laryngeal squamous cell carcinoma specimens were enrolled in the study. FHIT expression was detected by an immunohistochemical method. Rabbit polyclonal antibody was used for immunohistochemical study. FHIT expression was low in ...

Loss of fragile histidine triad expression in colorectal carcinomas and premalignant lesions.

Abnormal expression of the fragile histidine triad (FHIT) candidate tumor suppressor gene has been observed in a variety of human tumors, but little is known about its expression during colorectal tumorigenesis. Sections of 70 aberrant crypt foci (ACF), 55 adenomas, 84 primary colorectal carcinomas, and 13 metastatic lesions were evaluated immunohistochemically for Fhit expression. All normal c...

N-Terminal Domain of Fragile Histidine Triad Exerts Potent Cytotoxic Effect in HT1080 Cells

Fragile histidine triad (FHIT) serves a critical function as a tumor suppressor that inhibits p53 degradation by mouse double minute 2 (MDM2). The functional domains of FHIT involved in tumor inhibition was interpreted. In-silico screening data were employed to construct truncated forms of FHIT to assess their cytotoxic effects on the HT1080 cell line. Full FHIT expression was confirmed by west...
