ABSTRACT
Objective:
To study the efficacy and mechanism of Shugan Jianpi Jiedu prescription (SJJ) in the treatment of triple-negative breast cancer through <italic>in vitro</italic> cell experiments.Method:
The following groups were set up in this study: a normal serum group,a pirarubicin group,and low-,medium-, and high-dose SJJ-medicated serum groups. Twenty SD rats were randomly divided into four groups and administered with SJJ solution (16.8,8.2,4.05 g·kg<sup>-1</sup>) and normal saline (equal volume) according to the body surface area to prepare serum. MDA-MB-231 cells were treated separately. The proliferation, migration and invasion of MDA-MB-231 cells were detected by the cell counting kit-8(CCK-8),wound healing assay and transwell cell invasion assay. The phosphoinositide 3-kinase (PI3K),protein kinase B (Akt), and mechanistic target of rapamycin (mTOR) protein expression levels in MDA-MB-231 cells were tested by the Western blot.Result:
The cell proliferation in the three different doses of medicated serum groups and the pirarubicin positive control group was significantly inhibited as compared with that in the normal serum group(<italic>P</italic><0.01),and there was no statistical difference for this between the medium/high dose medicated serum group and the pirarubicin positive control group.The wound healing in the SJJ-medicated serum groups and the pirarubicin group was slowed down as compared with that in the normal serum group (<italic>P</italic><0.01),and the effect in the SJJ-medicated serum groups was weaker than that in the pirarubicin group (<italic>P</italic><0.05,<italic>P</italic><0.01). The number of cells invading the lower transwell chamber was decreased as compared with that in the normal serum group (<italic>P</italic><0.01),and there was no statistical difference between the medium-/high-dose SJJ-medicated serum groups and the pirarubicin group. Western blot results showed that 48 h after treatment,the PI3K,Akt, and mTOR expression levels in the cells of SJJ-medicated serum groups and the pirarubicin group were lower than those of the normal serum group(<italic>P</italic><0.01).Conclusion:
The SJJ-medicated serum could inhibit the proliferation, migration and invasion of MDA-MB-231 cells presumedly by down-regulating the protein expression levels in the PI3K/Akt/mTOR signaling pathway.
