摘要：The FHIT gene is a tumor suppressor that is frequently inactivated by genomic alterations at chromosomal region 3p14.2. In the last few years, a considerable amount of data describing inactivation of FHIT in a variety of human malignancies and demonstrating the tumor suppressor potential of Fhit have been reported. Despite the demonstration that FHIT functions as a tumor suppressor, the pathway through which Fhit induces apoptosis and inhibits growth of cancer cells is not known. Our data demonstrate that Fhit is a target of tyrosine phosphorylation by the Src protein kinase. We show that Src phosphorylates Y114 of Fhit in vitro and in vivo, providing insight into a biochemical pathway involved in Fhit signaling.
