ILK and in situ carcinoma: Similar results for ILK protein levels (37.0% reduction; ** p < 0.01, Figure S2A,B), colony formation (66.8% reduction; * p < 0.05, Figure S2C), and cell invasion (61.6% reduction; **** p < 0.0001, Figure S2D) were observed when transfecting ILK-siRNA(2) into OV90CIS cells, another HGSOC cell line resistant to CIS.
