ESRP1 and breast cancer: Our results suggest that ESRP1 has a cancer-promoting role in OC, similar to its metastasis-promoting role in breast cancer.18 However, a recent study by Lu et al.17 explored the clinical significance of ESRP1 in various cancer types using TCGA RNA-sequencing data across 13 types of cancers, including OC, but did not detect a significant association of ESRP1 with clinical outcome in OC.
