In various studies of sporadic breast cancers, 40-70% were strongly positive for fragile histidine triad (Fhit) protein expression, whereas only 18% of BRCA2 mutant breast cancers demonstrated strong Fhit expression, suggesting that the BRCA2 repair function may be necessary to retain intact fragile common chromosome fragile site 3B(FRA3B)/FHITloci. In the current study, 22 breast tumors with d...
The fragile histidine triad (Fhit) gene, which is frequently lost in many cancers, was identified as a candidate tumor suppressor gene at chromosome 3p locus 14.2. Loss of Fhit expression is an important step in tumor progression from premalignancy, to in situ, to invasive breast carcinoma. To determine whether the absence of Fhit protein correlates with other established pathological-clinical ...
The fragile histidine triad (FHIT), frequently lost in many cancers, was identified as a candidate tumor suppressor gene at chromosome 3p locus 14.2. Loss of the FHIT protein because of the alteration or loss of heterozygosity by genetic deletion occurs in a variety of epithelial tumors including head and neck cancer. However, the biological function of the FHIT protein is still unknown and its...
BACKGROUND Allelic losses in the short arm of chromosome 3 are common in cervical carcinomas. The fragile histidine triad (FHIT) gene at chromosome region 3p14.2 is a candidate tumor suppressor gene that may play a role in cervical tumorigenesis. We and others have identified aberrant FHIT transcripts and frequent loss of Fhit protein expression in primary cervical cancers and high-grade noninv...
Fragile histidine triad protein (Fhit) is a diadenosine triphosphate (ApppA) hydrolase encoded at the human chromosome 3 fragile site which is frequently disrupted in tumors. Reintroduction of FHIT coding sequences to cancer cell lines with FHIT deletions suppressed the ability of these cell lines to form tumors in nude mice even when the reintroduced FHIT gene had been mutated to allow ApppA b...
