Effect of Shenqi Fuzheng Injection in Improving Sensitivity of Human Breast Cancer MDA-MB-231 Cells to Cisplatin Through Tumor Associated Macrophages
To investigate the effect of Shenqi Fuzheng injection on the sensitivity of cisplatin through immunomodulation
in order to explore its mechanisms.
Method:
2
The cell survival was measured by thiazolyl blue tetrazolium bromide (MTT)
the rate of apoptosis was detected by flow cytometry
the expressions of apoptosis-related proteins were detected by Western blot
and the expression level of cytokines was detected by enzyme linked immunosorbent assay (ELISA).
Result:
2
Shenqi Fuzheng injection 1
10
100 mL·L
-1
significantly inhibited the growth of co-cultured cells
and the cell survival rate was 71.8%and 59.9%at the concentration of 10
100 mL·L
-1
respectively.Shenqi Fuzheng injection 10 mL·L
-1
combined with cisplatin significantly increased the sensitivity of co-cultured cells to cisplatin.The half maximal inhibitory concentration (IC
50
) of cisplatin was reduced from 30 to 15 μmol·L
-1
.The rate of apoptosis induced by the combined treatment increased by 15.5%compared with that of cisplatin 15 μmol·L
-1
(
P
<
0.05). The expressions of B-cell lymphoma-2 (Bcl-2)
B-cell lymphoma-w (Bcl-w) and B-cell lymphoma-extra large (Bcl-xl) were inhibited
and the expressions of Bcl-2-associated X protein (Bax) and protein induced by BH3 domain (Bid) apoptosis were increased (
P
<
0.05). Shenqi Fuzheng injection reduced the release of interleukin-10 (IL-10) and prostaglandin E
2
(PGE
2
) induced by cisplatin (
P
<
0.05).
Conclusion:
2
Shenqi Fuzheng injection improves the sensitivity of MDA-MB-231 to cisplatin by regulating immune cells
and plays a synergistic role in inhibiting the proliferation of breast cancer cells.This study provides experimental basis for the prevention and treatment of tumors with Yiqi Fuzheng method
and experimental reference for the study of traditional Chinese medicine in alleviating drug resistance of tumors.
