Pterostilbene inhibits ER stress and restores autophagic flux in the IUGR colon. a qRT-PCR analysis was performed to determine the mRNA abundance of GRP78, GRP94, CHOP, ATF4, and sXBP-1 in the colon; b, c The protein levels of ER stress markers, UPR sensors, and autophagy-associated molecules were determined by Western blot analysis. Data from at least three independent experiments were presented as mean ± SE (n = 6). ^*P < 0.05
