Recently a study showed that miR-29a can inhibit the 3′-UTR of STAT3 mRNA, reduce the level of STAT3, phosphorylated STAT3 and Bcl-2, inhibit cell proliferation, and enhance the level of apoptosis and drug sensitivity.147 Li et al.148 found that sulforaphane can upregulate the level of miR-124-3p in NPC cells, inhibit the 3′-UTR of STAT3 mRNA, enhance cell apoptosis, and inhibit cell proliferation. This evidence concerns the gene STAT3 and nasopharyngeal carcinoma.
