Figure 3. Overexpression of FADS1 promotes proliferation of PIG3V melanocytes. PIG3V cells were transduced with lenti-NC or lenti-FADS1 for 72 h. (A) Cell viability determination (CCK-8 assay). (B, C) Ki67 immunofluorescence. (D, E) Western blot detection of FADS1. **P < 0.01, compared with the NC group.
