Altered ERK1/2 Signaling in the Brain of Learned Helpless Rats: Relevance in Vulnerability to Developing Stress-Induced Depression
mRNA levels of RSK1 and MSK2 in frontal cortex (FC) (a) and hippocampus (b) of tested controls (TC), non-learned helpless (non-LH), and learned helpless (LH) rats. Data are the mean ± SD from 6 rats in each group. Overall group differences in the 3 groups are as follows. FC: , , and ; hippocampus: , , and .
