  1. 01LabIn vitro (cells)Efficacy outcome

    In PC12 cells expressing expanded polyglutamine stretches, humanin suppressed apoptotic cell death, but the suppression was incomplete.

    Summary
    we showed that HN suppresses apoptotic cell death induced by expanded polyQs.
    2 context sentences
    Summary · context
    However, the suppression was incomplete, suggesting that polyQs also stimulate other pathogenic cascades unrelated to ASK1.
    Summary · context
    To test the anti-ASK1 effect of HN on polyQ neurotoxicity, we constructed neuronal PC12 cells expressing expanded polyQs under the control of the Tet-Off system.
  2. 02LabIn vitro (cells)Mechanism

    In PC12 cells expressing expanded polyglutamine stretches, humanin suppressed polyQ aggregate formation.
