Mechanism Description In this study, we demonstrated that Mcl-1 overexpression induced resistance to IMQ-induced apoptosis and reduced both IMQ-induced ROS generation and oxidative stress in cancer cells. Mcl-1 overexpression maintained mitochondrial function and integrity and prevented mitophagy in IMQ-treated cancer cells. Furthermore, IL-6 protected against IMQ-induced apoptosis by increasing Mcl-1 expression and attenuating IMQ-induced mitochondrial fragmentation. Mcl-1 overexpression ameliorates IMQ-induced ROS generation and mitochondrial fragmentation, thereby increasing mitochondrial stability and ultimately attenuating IMQ-induced cell death. Investigating the roles of Mcl-1 in mitochondria is a potential strategy for cancer therapy development.

Mechanism Description Imidazoquinolines IMQ, RSQ, and GDQ are substrates for P-gp and begins to elucidate differences in their trafficking in cancer cells as a consequence of acquired drug resistance. We believe this work that begins to examine imidazoquinoline trafficking will prove useful in the future rational design of immunotherapeutics with enhanced susceptibility to P-gp efflux that enable increased bioavailability, in MDR cancers.
