E2F3 and non-small cell lung carcinoma: qRT-PCR and Western blot showed that overexpression of MCM3AP-AS1 promoted E2F3 expression, while miR-195-5p mimics counteracted the function of MCM3AP-AS1 in NSCLC cells; conversely, MCM3AP-AS1 knockdown inhibited E2F3 expression, while miR-195-5p inhibitors reversed such effect (Figure 5d–e).
