To investigate the influence of ING5 on the biological behaviors of ovarian cancer cells, ING5 siRNA was used to reduce the expression of ING5 in A2780 and SKOV3 cells: as shown in Fig. 4a, the expression of ING5 in A2780 or SKOV3 cells was reduced, respectively (P < 0.01). The gene discussed is ING5; the disease is ovarian carcinoma.
