Figure 4. LOC389641 knockdown impairs colony formation and invasion in lung cancer cells. (A, B), Colony formation is decreased after LOC389641 knockdown with siRNAs on H1299 cell line. (B) is the relative quantified value. ** p < 0.01 by t test. (C, D), Silencing of LOC389641 by siRNAs decreased cellular invasion ability in H1299 and H838 cell lines (10X). (D) are the relative quantified value. ** p < 0.01 by t test.
