MRPS9-AS1: MRPS9-AS1 is a long non-coding RNA (lncRNA) that has been studied in relation to prognosis in various types of cancer, including colon cancer and pRCC (papillary renal cell carcinoma) [PMC9863050]. In a study, five lncRNAs, including MRPS9-AS1, were identified as poor prognostic predictors in colon cancer patients [PMC9863050]. The expression of MRPS9-AS1 was found to be elevated in high-risk patients with colon cancer, indicating its association with a poor prognosis [PMC9863050]. Furthermore, a prognostic model was constructed using five lncRNAs, including MRPS9-AS1, which showed high accuracy in predicting overall survival [PMC9863050]. In another study on pRCC patients, MRPS9-AS1 was identified as one of the five prognostic-associated lipid metabolism-related lncRNAs [PMC9590147]. The expression levels of MRPS9-AS1 and the other four lncRNAs were found to be associated with molecular subtypes [PMC9590147]. A risk score equation was developed using the expression levels of these five lncRNAs to better predict patient prognosis [PMC9590147]. This research on the relationship between MRPS9-AS1 and tumor prognosis is considered the first of its kind [PMC9590147]. The findings suggest that MRPS9-AS1 has potential as a prognostic biomarker and can guide personalized immunotherapy and medication for pRCC patients based on individual differences [PMC9863050][PMC9590147].
