Aberrant splicing of FHIT transcripts in human gastric cancer cell lines.

Alterations of the FHIT gene occur as frequent events in several human cancers. Replacement of exogenous wild-type FHIT gene has been shown to induce suppression of tumorigenicity of human FHIT-negative cells in nude mice and aberrant FHIT transcripts have been observed in a variety of human solid tumors. In the presence study, we performed a nested reverse transcription-polymerase chain reaction (RT-PCR) analysis to identify aberrant FHIT transcripts in 6 gastric cancer cell lines.
