LINC00857 Knockdown Enhanced Radio-Sensitivity of A549 Cells

(A) Transfection efficiency measured by qRT-PCR. (B) Viability of A549 cells after LINC00857 knockdown tested using CCK-8. (C) Flow cytometric detection on A549 cell apoptosis after LINC00857 knockdown. (D) Colony formation ability of A549 cells after LINC00857 knockdown. (E) Western blot analysis of Ki67, PCNA, Bax, and Bcl-2 protein expression in A549 cells after LINC00857 knockdown. ∗p < 0.05 versus si-NC; measurement data were expressed as mean ± standard deviation and analyzed by unpaired t test. OD values at different time points were compared using two-way ANOVA. The cell experiments were conducted three times independently.
