PG - 563-570 LID - 10.2174/1389203723666220823152239 [doi] AB - BACKGROUND: The roles of T-Box transcription factor (TBX2) in endometrial cancer are still not clear. This study was designed to explore the roles of TBX2 in endometrial cancer and the underlying mechanisms. METHODS: The knockdown and overexpression of TBX2 in endometrial cancer cell lines were constructed by using lentivirus transduction. The xenograft animal model was established by using stable endometrial cancer cell lines. Cell viability was determined by the CCK-8 assay. The mRNA and protein levels of target genes were determined by using qPCR and Western blotting, respectively. ChIP assay was used to determine the interactions between TBX2 and nuclear factor erythroid 2-related factor 2 (NRF2). RESULTS: The upregulation of TBX2 was observed in endometrial cancer tissues from patients with Cisplatin- resistance and Cisplatin-resistant cells. Interestingly, TBX2 regulated cell viability and Cisplatin resistance of endometrial cancer cells. In addition, the regulatory effects of TBX2 on chemo-resistance of endometrial cancer cells were associated with the NRF2 signaling pathways. Consistently, the endometrial cancer xenograft animal model revealed that TBX2 regulated tumor growth and Cisplatin resistance, and its regulatory effects were in part by the regulation of NRF2 signaling pathways. CONCLUSION: TBX 2 enhanced Cisplatin resistance of endometrial cancer by regulating the NRF2 signaling pathways.
