PDCD4 and gastric cancer: Moreover, compared with cells transfected with pre-miR-93 alone, those transfected with both pre-miR-93 and the PDCD4-overexpression plasmid exhibited significantly higher apoptosis rates (Fig. 5), suggesting that miR-93-resistant PDCD4 is sufficient to rescue the suppression of PDCD4 through miR-93 and attenuate the anti-apoptosis effect of miR-93 on gastric cancer cells.
