Fragile histidine triad expression delays tumor development and induces apoptosis in human pancreatic cancer.
The fragile histidine triad (FHIT) gene is a tumor suppressor gene that is altered by deletion in a large fraction of human tumors, including pancreatic cancer. To evaluate the potential of FHIT gene therapy, we developed recombinant adenoviral and adenoassociated viral (AAV) FHIT vectors and tested these vectors in vitro and in vivo for activity against human pancreatic cancer cells. Our data ...
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 کاملLoss 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...
متن کاملExpression 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 ...
متن کاملRestoration of fragile histidine triad (FHIT) expression induces apoptosis and suppresses tumorigenicity in lung and cervical cancer cell lines.
Loss of expression of the Fhit protein is often associated with the development of many human epithelial cancers, including lung and cervical carcinomas. Restoration of Fhit expression in cell lines derived from these tumors has however yielded conflicting results, prompting the need for careful evaluation of the oncosuppressive potential of FHIT. In the present study, we have investigated the ...
