TAL1 and glioma: In addition, our results showed that overexpression of miR-346/miR-425-5p decreased TAL1 mRNA and protein expression, and inhibited the malignant biological behavior of glioma, while miR-346 and miR-425-5p knockdown showed opposite effects, suggesting that miR-346 and miR-425-5p negatively regulate the expression of TAL1 mRNA and protein at the post-transcriptional level and exert regulatory effects on the biological behavior of glioma cells.
