  • The endoplasmic reticulum (ER) is a multifunctional intercellular organelle in which several posttranslational modification steps occurred such as protein folding, lipid biosynthesis, calcium storage and release. Perturbations that disrupt ER homeostasis lead to the misfolding of proteins in the ER lumen and up-regulation of ER signaling pathway called the unfolded protein response (UPR). Here, we have demonstrated that ageing changes the expression of ER chaperone and associated ER membrane kinases of IRE1, ATF6 and PERK.
