ABSTRACT
ObjectiveTo investigate the mechanism of Baitouweng Tang in inhibiting the growth of esophageal cancer (EC) cells by regulating budding uninhibited by benzimidazoles 1 (BUB1)/signal transducer and activator of transcription 3 (STAT3) signaling pathway. MethodGene chip technology was used to explore the differential gene expression between esophageal cancer tissues and normal tissues and identified differentially expressed genes. The differentially expressed genes were analyzed by bioinformatics methods. EC cells were treated with 25, 50, 100, 200, 400, 800 mg·L-1 Baitouweng Tang. EC cell viability was detected by Thiazolyl Blue (MTT) colorimetry. Cell cycle and apoptosis were measured by flow cytometry. The expression of BUB1 was measured by real time quantitative polymerase chain reaction (Real-time PCR). The protein levels of BUB1, STAT3, phosphorylated (p)-STAT3, Cyclin B1 (CCNB1), cyclin-dependent kinase 1 (CDK1), B-cell lymphoma-2 (Bcl-2), cysteinyl aspartate-specific proteinase(Caspase)-3, and Caspase-9 were measured by Western blot. The migration and invasion abilities of the cells were measured by wound-healing and Transwell invasion assays. ResultDifferentially expressed genes were primarily involved in biological processes, signaling pathways, and network construction related to cell mitosis, with BUB1 identified as a key core gene. Compared with the control group, Baitouweng Tang inhibited BUB1 expression (P<0.05,P<0.01). In vitro experiments showed that compared with the control group, Baitouweng Tang could significantly inhibit the growth (P<0.05,P<0.01), migration and invasion (P<0.05,P<0.01) of EC cells, induce apoptosis (P<0.05,P<0.01), and cause G2/M phase increase (P<0.01). After treatment with Baitouweng Tang, compared with the results in the control group, the expression of Caspase-3, and Caspase-9 in EC cells increased significantly (P<0.05,P<0.01), while the expression of Bcl-2, BUB1, CCNB1, and CDK1 decreased significantly (P<0.05,P<0.01). Moreover, the STAT3 signaling pathway was also found to play an important role in this process. ConclusionBaitouweng Tang may inhibit the growth of EC cells by downregulating BUB1 and mediating the STAT3 signaling pathway.
