In addition to targeting Smo and blocking Hh signaling, 1 can also interfere with myriad other harmfully mutated biological processes: it has been shown to inhibit growth of breast cancer and erythroleukemia cells through mechanisms outside of Smo binding [59,60], and has been shown to induce apoptosis in human prostate cancer cells [61]. The gene discussed is SMO; the disease is breast carcinoma.
