Effect of miR-29b-1-5p on signal transducer and activator of transcription 3 (STAT3) protein phosphorylation in K562 cells. a Increased miR-29b-1-5p expression in K562 cells after transfection with miR-29b-1-5p mimic versus scramble oligonucleotides. b The phosphorylation ratio of STAT3 decreased in K562 cells after transfection with miR-29b-1-5p mimic compared with those transfected with scramble oligonucleotides after culturing with medium for 48 h. c A representative case
