From: Up-regulated expression of E2F2 is necessary for p16INK4a-induced cartilage injury
(a) ELISA assay for the secretion of SASP markers after the over-expression of p16INK4a. (b) RT-PCR for detecting the expressions of Col2A1, p16INK4a and E2F2. (c) The expressions of Col2A1, p16INK4a and E2F2 by Western blot assay. *P < 0.05 and **P < 0.01 vs. empty. Empty, cells were transfected with over-expression empty vector; p16INK4a, cells were transfected with p16INK4a over-expression vector. Data were shown as mean ± SD, n = 5
