Endoplasmic reticulum protein 29 is involved in endoplasmic reticulum stress in islet beta cells.
Endoplasmic reticulum stress (ERS) is correlated with insulin resistance and islet‑cell function. In the present study, the sub‑cellular localization and role of ER protein 29 (Erp29) were investigated in an in vitro ERS model of islet beta cells. The INS‑1 islet cell line was treated with various concentrations of tunicamycin to establish the ERS model. Immunofluorescence microscopy demonstrat...
متن کاملEndoplasmic Reticulum Stress and Associated ROS
The endoplasmic reticulum (ER) is a fascinating network of tubules through which secretory and transmembrane proteins enter unfolded and exit as either folded or misfolded proteins, after which they are directed either toward other organelles or to degradation, respectively. The ER redox environment dictates the fate of entering proteins, and the level of redox signaling mediators modulates the...
متن کاملEndoplasmic Reticulum Stress PERK-ATF4-CHOP Pathway Is Associated with Hypothalamic Neuronal Injury in Different Durations of Stress in Rats
The hypothalamus, which is the initial part of the hypothalamic-pituitary-adrenal (HPA) axis, plays a critical role in regulating stress in the central nervous system. The present study aimed to determine whether endoplasmic reticulum stress in hypothalamic neurons is differentially stimulated by varying durations of stress exposure, which ultimately leads to pathological changes in neurons by ...
متن کاملSecretion of the endoplasmic reticulum stress protein, GRP78, into the BALF is increased in cigarette smokers
BACKGROUND Identification of biomarkers of cigarette smoke -induced lung damage and early COPD is an area of intense interest. Glucose regulated protein of 78 kD (i.e., GRP78), a multi-functional protein which mediates cell responses to oxidant stress, is increased in the lungs of cigarette smokers and in the serum of subjects with COPD. We have suggested that secretion of GRP78 by lung cells m...
متن کاملIncreased endoplasmic reticulum stress in atherosclerotic plaques associated with acute coronary syndrome.
BACKGROUND The endoplasmic reticulum (ER) responds to various stresses by upregulation of ER chaperones, but prolonged ER stress eventually causes apoptosis. Although apoptosis is considered to be essential for the progression and rupture of atherosclerotic plaques, the influence of ER stress and apoptosis on rupture of unstable coronary plaques remains unclear. METHODS AND RESULTS Coronary a...
