Cerebral ischemia increases small ubiquitin-like modifier conjugation within human penumbral tissue: Radiological-pathological correlation

Abstract

  • © 2018 Bernstock, Ye, Griffin, Lee, Lynch, Latour, Friedman, Maric and Hallenbeck. Posttranslational modification by small ubiquitin-like modifier (SUMO) regulates myriad physiological processes within cells and has been demonstrated to be highly activated in murine brains after cerebral ischemia. Numerous in vitro and murine in vivo studies have demonstrated that this increased SUMO conjugation is an endogenous neuroprotective stress response that has potential in being leveraged to develop novel therapies for ischemic stroke. However, SUMO activation has not yet been studied in poststroke human brains, presenting a clear limitation in translating experimental successes in murine models to human patients. Accordingly, here, we present a case wherein the brain tissue of a stroke patient (procured shortly after death) was processed by multiplex immunohistochemistry to investigate SUMO activation.
