Peptide RIFV did not influence the proliferation, apoptosis or cell cycle of human white preadipocytes. a Cells were cultured in PAM containing RIFV (NC, 10 μM, 50 μM and 100 μM) for 24 h, 48 h, 72 h, and the cell proliferation level was assessed via a CCK-8 assay. b Apoptosis and c cell cycle of human white preadipocytes treated with RIFV for 24 h were analyzed by flow cytometry. The values represent the means ± SD, n = 3. *P < 0.05, **P < 0.01
