USP30 and ovarian cancer: For our study, we sought to construct a risk model that could guide the prognosis of ovarian cancer patients, which consisted of five m7G-related lncRNAs (KRT7-AS, USP30-AS1, ZFHX4-AS1, ACAP2-IT1, and TWSG1-DT) could not only serve as an independent prognostic factor for ovarian cancer patients, but also it was indicative of instructing and predicting the overall survival of ovarian cancer.
