Influence of nitric oxide synthase activity on amino acid concentration in the quinolinate lesioned rat striatum: a microdialysis and histochemical study.

abstract：:In a previous research, we have shown that adequate levels of polyamines are required in transformed mouse fibroblasts for the correlated activations of MAPK subtypes (ERK and JNK) and caspases induced by etoposide and leading to apoptosis. We report now that the treatment of fibroblasts with etoposide also elicited a...
