In contrast, chelating intracellular calcium ( [ Ca ( 2+ ) ] ( i ) ) by BAPTA-AM abolished
BDNF mediated

ERK alone is not
sufficient to up-regulate
Arc transcription ... Moreover, we found that inhibition of
calmodulin (CaM) by W13
blocked both
Arc transcription and ERK activation, revealing a Ca ( 2+ ) -independent function of CaM

Together with the results of our previous studies showing that c-fos gene expression was induced by systemic administration of GH and that GH receptor mRNA was contained in somatostatin neurons in the PeV and NPY neurons in the ARC, the data of the present study indicate that GH, but not
IGF-I ,
acts on the cells in the
ARC and the PeV or in their vicinity to inhibit its own secretion, presumably by activating the somatostatin and NPY neurons
