Adipose stromal cells conditioned media (ASC-CM) protect neurons in a variety of neuronal death models including potassium/serum deprivation-induced neuronal apoptosis. In this study, we found that ASC-CM contained glutamate oxaloacetate transaminase and its substrate, oxaloacetate (OAA) directly protected cerebellar granule neurons (CGN) from apoptosis induced by serum and potassium deprivation. Additionally, OAA inhibited serum and potassium deprivation-induced caspase 3 activation. ASC-CM and OAA in combination had a synergistic neuroprotective effect. Clearly, different from ASC-CM-induced neuroprotection, OAA-induced neuroprotection was Akt- independent but JNK-dependent. These data establish a mechanistic basis supporting that the application of ASC-CM for neuroprotective treatments could be significantly enhanced by addition of OAA.
