To determine whether PINK1‐dependent mitophagy in the microenvironment would affect myeloma development, the syngeneic transplantable VK*MYC myeloma mouse model was used.23 VK*MYC myeloma splenocytes were injected via tail vein into 10–12 week old, nonirradiated syngeneic pink1−/− knockout mice (on C57Bl/6 background) or pink1+/+ C57Bl/6 littermates (Figure9A). This evidence concerns the gene PINK1 and plasma cell myeloma.
