Parkin cell signaling
WebIn the present study, we show that PLC signaling is altered in parkin deficient human neuroblastoma cell lines, resulting in a distrupted [Ca 2+] homeostasis and increased vulnerability to 6OHDA. We further show that blocking of PLC activity or Ryanodine receptors (RyR) could reverse these effects. WebParkin sequestration and parkin-suppressed cell death may go hand in hand, supporting a potential role for cell toxicity mediated by protein aggregation or aberrant UPS function …
