After studies showing that exposure to BTZ induced an upregulation of miRNA 198 (miR-198) while depletion of the miR significantly reversed the inhibitory effect of BTZ on cell proliferation [230], further studies on miR-198 revealed the 3′-UTR of HMGA1 as a downstream target of miR-198, suppressing the expression of HMGA1 in DLBCL cells. This evidence concerns the gene HMGA1 and diffuse large B-cell lymphoma.
