The Fragile Histidine Triad Gene: A Molecular Link Between Cigarette Smoking and Cervical Cancer

The fragile histidine triad gene: a molecular link between cigarette smoking and cervical cancer.

PURPOSE Smoking is an epidemiologic risk factor for cervical cancer. The fragile histidine triad (FHIT) gene is a tumor suppressor gene that is altered in 80% of tobacco-associated lung cancers. We hypothesized that reduced FHIT protein expression, homozygous deletions (HD) or hemizygous deletions (HemiD) and microsatellite alterations (MA) at the FHIT/FRA3B locus occur more commonly in cervica...

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 ...

Molecular and epigenetic analysis of the fragile histidine triad tumour suppressor gene in equine sarcoids

BACKGROUND Sarcoids are peculiar equine benign tumours. Their onset is associated with Bovine Papillomavirus type -1 or -2 (BPV-1/2) infection. Little is known about the molecular interplay between viral infection and neoplastic transformation. The data regarding papillomavirus infections in human species show the inactivation of a number of tumour suppressor genes as basic mechanism of transfo...
