Compared with cells treated with miR‐27a mimic and expression vectors containing TGFBR1 3′UTR, cell migration, invasion (Figure 4A), and proliferation (Figure 4B) ability were significantly downregulated in both DLBCL cell transfected with TGFBR1 expression vectors missing 3′UTR only, TGFBR1 expression vectors containing TGFBR1 3′UTR only, and TGFBR1 expression vectors missing 3′UTR and miR‐27a mimic co‐transfected group. The gene discussed is TGFBR1; the disease is diffuse large B-cell lymphoma.
