When rabbit hippocampal cells are examined after a nictitating membrane conditioned response, up to three-fold activation of pkc is noted in synaptosomes of hippocampal CA1-3 regions (Sunayashiki-Kusuzaki et al., 1993), or to the stratum oriens of CA3 (Scharenberg et al., 1991), suggesting that pkc activity underlies associative learning processes
The restoration of this single glycine residue is thus sufficient to recover the GSH efflux stimulation, but not the drug transport, which further suggests a different mechanism for these two transport activities

Clinically, however, the evidence is mixed : Vitamin B12 has a well-established role in energy metabolism, especially in deficient individuals
