TPM-like manipulations exerted an antidepressant effect and regulated amino acid metabolism and GHR/IGF-1 pathway in the liver in adolescent female CUMS rats. (PubMed, Front Physiol)
Female Sprague-Dawley rats (3-4 weeks) were randomly divided into four groups (n=7-8): control (CON), chronic unpredictable mild stress (CUMS), CUMS + TPM-like manipulations (TPM), and CUMS + fluoxetine (FLX)...TPM-like manipulations prevented CUMS-induced depressive-like behaviors, increased concentration of L-Aspartic Acid, increased the expressions of GHR and IGF-1 in the liver, increased the expressions of IGF-1 and IGF-1R, and inhibited inflammation in the hippocampus in adolescent female rats. However, further study is warranted to draw confirmative results related to liver-brain axis.
