1 Z-Guggulsterone Improves the Scopolamine-Induced Memory Impairments Through Enhancement of the BDNF Signal in C57BL/6J Mice. pregna-4,17-diene-3,16-dione brain derived neurotrophic factor Mus musculus
2 Mechanistic studies revealed that Z-guggulsterone pretreatment reversed the scopolamine-induced increase in acetylcholinesterase (AchE) activity, as well as decreases in brain-derived neurotrophic factor (BDNF) protein expression and cAMP response element-binding protein (CREB), extracellular regulated kinase 1/2 (ERK1/2) and protein kinase B (Akt) phosphorylation levels in the hippocampus and cortex. pregna-4,17-diene-3,16-dione brain derived neurotrophic factor Mus musculus

4 Inhibition of the BDNF signal, however, blocked the memory-enhancing effect of Z-guggulsterone. pregna-4,17-diene-3,16-dione brain derived neurotrophic factor Mus musculus
5 Therefore, these findings demonstrate that Z-guggulsterone attenuates the scopolamine-induced memory impairments mainly through activation of the CREB-BDNF signaling pathway, thereby exhibiting memory-improving effects. pregna-4,17-diene-3,16-dione brain derived neurotrophic factor Mus musculus
