Overexpression of miR-34a-5p inhibited proliferation and promoted apoptosis of DLBCL cells, while SNHG17 knockdown and co-expression of miR-34a-5p attenuated this effect, indicating that SNHG17 could affect the proliferation of DLBCL cells by adsorbing miR-34a-5p. This evidence concerns the gene SNHG17 and diffuse large B-cell lymphoma.
