Next, we used qRT-PCR to detect the mRNA expression level of Myd88 in HCC cells treated with Lnc-Myd88, and found that compared with the controls, there were increased expression of Myd88 in Lv-Lnc-Myd88-SMMC-7721 cells, whereas the expression level of Myd88 was decreased in the sh-Lnc-Myd88-Huh7 cells (Figure 5d). The gene discussed is MYD88; the disease is hepatocellular carcinoma.
