Abstract:
The Hedgehog (Hh) pathway is activated in some human cancers, including gastric cancer(GC). The glioma associated oncogene homolog (Gli) transcription factors are critical mediators of the activated Hh pathway, and their expression may be elevated in some tumors independent of upstream Hh signaling. Thus, therapies targeting Gli transcription factors may benefit a wide spectrum of patients with mutations at different nodal points of the Hh pathway. In this study, we present evidence that arsenic trioxide (ATO) suppresses GC cell growth by inhibiting Gli2, and decreased expression of en-dogenous Gli2 target genes. Our results warrant the clinical investigation of ATO for tumors with activated Hh/Gli sig-naling, in particular patients who develop resistance to current therapies targeting the Hh pathway upstream of Gli.
