| Abstract |
Depression is characterized by a pathological injury to the hippocampal neurons. Senkyunolide A (SenA) is one of the major active components of Dan-zhi-xiao-yao-san, which is widely used in the treatment of depression-related disorders. In the present study, it was hypothesized that the antidepressant effect of Dan-zhi-xiao-yao-san depended on the function of SenA and the authors attempted to reveal the molecular mechanism associated with the treatment. An in vitro depression model was induced using corticosterone (Cort), and the effect of SenA on the cell viability, apoptosis, and protein phosphatase 2A/α-synuclein (PP2A/α-syn) signaling was detected. To validate the mechanism driving the therapeutic effect of SenA, activity of PP2A and α-syn was modulated and the effect on neural cells was evaluated. The results showed that SenA protects Cort-induced cell apoptosis in PC12 cells. In addition, SenA increased Cort-induced reduction of PP2A activity, while it decreased the expression of p-PP2A, α-syn, and p-α-syn (Ser129). Further, modulation of PP2A activity with specific inhibitor okadaic acid (OA) increased Cort-induced cell apoptosis, while PP2A activator D-erythro-sphingosine (SPH) exhibited an opposite effect. The neuroprotective effects of SenA on neural cells also depended on inhibition of α-syn function, the regulation of which would influence the activity of PP2A in a negative loop. Collectively, the results suggested that the neuroprotective effects of SenA were exerted by modulating activities of PP2A activities and α-syn. The findings partially explained the mechanism associated with the neuroprotective effect of SenA. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 01 November 2018.
All research outputs
#20,663,600
of 25,385,509 outputs
Outputs from Drug Design, Development and Therapy
#1,436
of 2,268 outputs
Outputs of similar age
#267,264
of 342,877 outputs
Outputs of similar age from Drug Design, Development and Therapy
#47
of 63 outputs
Altmetric has tracked 25,385,509 research outputs across all sources so far. This one is in the 10th percentile – i.e., 10% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,268 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.1. This one is in the 22nd percentile – i.e., 22% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 342,877 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 63 others from the same source and published within six weeks on either side of this one. This one is in the 15th percentile – i.e., 15% of its contemporaries scored the same or lower than it.
