Kainic acid-induced apoptosis in cerebellar granule neurons: an attempt at cell cycle re-entry.

This study was undertaken to investigate whether kainic acid (KA) may regulate the expression of several proteins which plays an important role in cell-cycle progression in cerebellar granule neurons (CGNs). KA induced decrease in MTT values in a concentration dependent way. Flow cytometric analysis showed that KA was able to induce 30% apoptosis in CGNs.
