Fig. 4From: Matrix-derived inflammatory mediator N-acetyl proline-glycine-proline is neurotoxic and upregulated in brain after ischemic strokeDetection of ac-PGP in culture medium and neuronal cell extracts after OGD. Ac-PGP was detected by LC-MS in a unused, control, and OGD culture medium and b whole-cell extracts of control cells or cells after 2-h OGD and 24-h reoxygenation. Ac-PGP was significantly increased in control (*p < 0.005) and OGD (# p < 0.05) culture medium compared to unused culture mediumBack to article page
