    OGD/R induces early activation of ER stress sensors followed by apoptosis in cultured cortical neurons, which is ameliorated by ER stress inhibitors. (A) Schematic representation of the timeline of the experimental procedures. Cortical neurons (7 DIV) were cultured in normal conditions (Control group) or exposed to oxygen/glucose deprivation for 4 hours followed by reperfusion (OGD/R group). Cell lysates were collected at various time points for Western blotting, and cell viability was evaluated after 24 hours reperfusion. (B) The cell viability of primary cortical neurons after OGD/R 24 hours was detected by MTT assay. Cortical neurons (7 DIV) under standard culture conditions were used as the control group ( n = 3). ** P < 0.01, vs. control, unpaired t -test. (C) Cell lysates from the OGD/R group were collected at different time points (0–24 hours) after reperfusion. For the control group, cell lysates were collected at the same time corresponding to 0 hours reperfusion of OGD/R group. Levels of ER stress sensors, protein synthesis, and apoptosis-related proteins were examined by western blot analysis.

    OGD/R induces early activation of ER stress sensors followed by apoptosis in cultured cortical neurons, which is ameliorated by ER stress inhibitors. (A) Schematic representation of the timeline of the experimental procedures. Cortical neurons (7 DIV) were cultured in normal conditions (Control group) or exposed to oxygen/glucose deprivation for 4 hours followed by reperfusion (OGD/R group). Cell lysates were collected at various time points for Western blotting, and cell viability was evaluated after 24 hours reperfusion. (B) The cell viability of primary cortical neurons after OGD/R 24 hours was detected by MTT assay. Cortical neurons (7 DIV) under standard culture conditions were used as the control group ( n = 3). ** P < 0.01, vs. control, unpaired t -test. (C) Cell lysates from the OGD/R group were collected at different time points (0–24 hours) after reperfusion. For the control group, cell lysates were collected at the same time corresponding to 0 hours reperfusion of OGD/R group. Levels of ER stress sensors, protein synthesis, and apoptosis-related proteins were examined by western blot analysis.
