Figure 10. To verify the expression level of RAB22A in clinical samples and cell lines. (A–D) Western blotting results showed that the expression level of RAB22A protein in MM patients was significantly higher than that in normal people. (E, F) qRT-PCR results showed that the expression level of RAB22 gene in MM patients was significantly higher than that in normal people. (G) CCK-8 assay showed that the OD value decreased after down-regulating the expression of RAB22A in MM cell lines.
