PRNP and gastric cancer: Western blot image (Figure 3A) and grayscale analysis (Figure 3B and 3C) showed that the expression of MGr1-Ag/37LRP protein were significantly increased in SGC7901/PrP compared with SGC7901/PCDNA3.1 and decreased in SGC7901/PrPi compared with SGC7901/Psilencer3.1 (p < 0.05), revealing a regulation of protein expression of MGr1-Ag/37LRP by PrPC in gastric cancer cells.
