In the S-HFD group subcutaneously injected with SCD1-KD OVCAR8 cells, the greatest tumor growth suppression was noted, with a significant difference compared with that in the O-HFD group (SCD1-KD and S-HFD vs. SCD1-KD and O-HFD; 0.02667 g vs. 0.0733 g, p = 0.019481; Fig. 6d–f). The gene discussed is SCD; the disease is neoplasm.
