The FRA3B, at 3p14.2, lies within the fragile histidine triad (FHIT) gene and is the most highly expressed of the common fragile sites observed when DNA replication is perturbed by aphidicolin. Common fragile sites are highly unstable regions of the genome. Large intragenic deletions within FHIT, localized within the FRA3B sequences, have been identified in a variety of tumor cells. To characte...
The fragile histidine triad (FHIT) gene located on chromosome 3p14.2 is frequently deleted in human tumors. We have previously reported deletions at the FHIT locus in 50% of bladder carcinoma derived cell lines and reduced expression in 61% of primary transitional carcinomas of the urinary bladder. To additionally investigate the role of FHIT alterations in the development of bladder cancer, we...
Fragile histidine triad (FHIT) gene deletion or promoter methylation and reduced Fhit protein expression occur in approximately 70% of human epithelial tumors and, in some cancers, are clearly associated with tumor progression. Specific Fhit signal pathways have not been identified. We previously reported that compared with Fhit+/+ cells, Fhit-/- cells with an overactivated ATR/CHK1 pathway sho...
The 3;8 chromosomal translocation, t(3;8)(p14.2;q24.1), was described in a family with classical features of hereditary renal cell carcinoma. Previous studies demonstrated that the 3p14.2 breakpoint interrupts the fragile histidine triad gene (FHIT) in its 5' noncoding region. However, evidence that FHIT is causally related to renal or other malignancies is controversial. We now show that the 8...
