Moreover, continuous exposure to sublethal concentrations of TRAIL induces an NFkB-dependent increase in miR-21, miR-30c and miR-100, which downregulates expression of caspase 8, caspase 3, TRAF7 and Foxo3a, resulting in acquired resistance to TRAIL and the development of more aggressive tumours (Jeon et al, 2015). The gene discussed is CASP8; the disease is neoplasm.
