Figure 4From: Long non-coding RNA MEG3 inhibits NSCLC cells proliferation and induces apoptosis by affecting p53 expression Effects of MEG3 on cell apoptosis. (A) Hoechst staining assay for cell apoptosis; the percentage of Hoechst-positive nuclei per optical field (at least 50 fields) was counted. (B) The apoptotic rates of cells were detected by flow cytometry. *P < 0.05 and **P < 0.01.Back to article page
