Icariin promotes HaCaT cell proliferation. (A) HaCaT cells were pretreated with MK-2206, GDC-0994, or medium alone without inhibitors for 2 h. Cells were then incubated with 30 μM icariin for 24, 48 and 72 h, and cell viability was measured by CCK-8 assay. (B) Western blot analysis of Cyclin D1 and D3 protein expression levels in HaCaT cells following treatment with medium alone (control), icariin, icariin with MK-2206 or icariin with GDC-0994. Data represent mean ± standard deviation of three independent experiments. *P<0.05, **P<0.01 and ***P<0.001 vs. untreated control. CCK-8, cell counting kit-8; OD, optical density.
