  Drug resistance is a major cause of failure in cancer chemotherapy.Therefore, identification and combined use of adjuvant compounds that can overcome drug resistance may improve the efficacy of cancer therapy.We screened extracts of Verticillium species-infected mushrooms for antitumor compounds and identified the compound Verticillin A as an inducer of hepatoma cell apoptosis in vitro and an inhibitor of tumor xenograft growth in vivo.Verticillin A exhibited a potent apoptosissensitizing activity in human colon carcinoma cells exposed to TRAIL or Fas in vitro.Furthermore, Verticillin A effectively sensitized metastatic human colon carcinoma xenograft to TRAIL-mediated growth inhibition in vivo.
