Abstract

Gastric cancer (GC) is one of the most common malignancies of the digestive tract. Adriamycin (ADR) has been widely utilized in various chemotherapy regimens for treating GC, yet its long-term application may increase drug resistance resulting in treatment failure. Increasing evidence shows that bioactive natural products can be used as chemotherapeutic sensitizers that can significantly improve chemotherapy sensitivity. Peiminine (PMI) is a biologically active component extracted from Fritillaria walujewii Regel. Thus, in the present study, we aimed to investigate whether peiminine (PMI) alters the chemosensitivity of GC to adriamycin (ADR). GC cells were treated with ADR with or without PMI. MTT assay, flow cytometry and a nude mouse tumor xenograft model of SGC7901 cells were used to evaluate the chemosensitization activity of PMI combined with ADR. Western blotting was used to examine the expression of cyclin D1 and cleaved PARP. The RayBio® Human RTK phosphorylation antibody array kit was used to test the differential protein expression. Compared with the ADR group, PMI combined with ADR significantly suppressed cell proliferation and induced cell apoptosis in vitro. The growth curve and tumor weight of the tumor xenografts were significantly decreased in mice treated with the combination of PMI and ADR. However, the organs showed no obvious abnormality after treatment with PMI plus ADR. The expression of cyclin D1 was decreased and the level of cleaved PARP was increased after treatment with PMI and ADR. The expression of p-EGFR and p-FAK was downregulated in cells treated with PMI and ADR, and the validation of p-EGFR and p-FAK was in accordance with the result of the phosphorylation antibody array kit. PMI may serve as a new chemosensitizer by inhibiting the proliferation and inducing the apoptosis to enhance the chemotherapeutic drug sensitivity of ADR in GC.
