SNHG17 and lymphoma: Our study confirmed for the first time that EZH2 was upregulated in lymphoma cells and negatively correlated with miR-34a-5p and proposed that the upstream target gene SNHG17 regulates the downstream EZH2 signaling pathway by adsorbing miR-34a-5p, which is probably the reason for the resistance of lymphoma cells to DOX.
