Figure 4. ZIP4 silencing down-regulated RANKL level under zinc-deficient condition.
Western blot showed that the knockdown of ZIP4 could attenuate the RANKL protein level in PC cells in Chelex zinc-chelating medium A. Quantification analysis confirmed that the expression level of RANKL normalized to β-actin was significantly decreased in AsPC-shZIP4 cells B. **P < 0.001
