Expression of heat shock protein 105 kDa (Hsph1), heat shock 27 kDa protein 1 (Hspb1), and oxidative stress regulators including Manf (Oh-hashi et al., 2015), cysteine-rich with EGF-like domain protein 2 (Creld2) (Oh-hashi et al., 2009), and cysteine and histidine rich domain containing 1 (Chordc1) (Gano and Simon, 2010) was significantly altered by postnatal overnutrition. This evidence concerns the gene CRELD2 and overnutrition.
