Results in Figure2A showed that nearly all chemotherapy drugs promoted the release of sGRP78 from E0771(GRP78‐mCherry) cells, as well as from melanoma B16‐F10(GRP78‐mCherry) cells (Figure S2B, Supporting Information), indicating chemotherapy‐induced sGRP78 release was a common phenomenon. The gene discussed is HSPA5; the disease is melanoma.
