Figure 6. Linc00472 suppressed tumor growthin vivo. (A) The tumor volume curve of null mice was analyzed. (B) The tumor weight of null mice was measured. (C) The miR-196a expression and PDCD4 mRNA levels in tumors of null mice were detected by qRT-PCR. (D) Western blot analysis was performed to determine PDCD4 and Ki-67 protein levels. *P < 0.05.
