  sub:_3 prov:value "Most of the studies that have assigned a proapoptotic role to the FHIT gene were performed in adenoviral-FHIT-transduced cancer cells expressing high levels of the Fhit protein. The present work was the first study designed to investigate the effects of FHIT gene replacement in a human FHIT-negative non-small-cell lung cancer (NSCLC) cell line (Calu-1) by using a hormone-inducible expression system that allows tight modulation of the transgene expression. An upregulation of p21waf1 transcript was found," ;
