UBE2S and cancer: Given the important role of UBE2S in several cancers, this study attempted to explore the expression level, clinical significance, and molecular mechanism of action of UBE2S in pan-gynecological cancers, especially in OV, through high-throughput data analysis and subsequent validation using clinical samples and in vitro experiments(Chandra et al. 2019; Ho et al. 2021; Stewart et al. 2019; Tang et al. 2021).
