To explore the mechanism through which FAM193B promotes the proliferation of ccRCC cells, we transfected Caki-1 cells with lentivirus empty vector, SH-FAM193B lentivirus, or OE-FAM193B lentivirus and used gene chips to detect genes displaying significant differential expression (Figure 7A, 7B). The gene discussed is FAM193B; the disease is nonpapillary renal cell carcinoma.
