Development and Validation of a Nine-Redox-Related Long Noncoding RNA Signature in Renal Clear Cell Carcinoma

Abstract

Background. Redox plays an essential role in the pathogeneses and progression of tumors, which could be regulated by long noncoding RNA (lncRNA). We aimed to develop and verify a novel redox-related lncRNA-based prognostic signature for clear cell renal cell carcinoma (ccRCC). Materials and Methods. A total of 530 ccRCC patients from The Cancer Genome Atlas (TCGA) were included in this study. All the samples were randomly split into training and test group at a 1 : 1 ratio. Then, we screened differentially expressed redox-related lncRNAs and constructed a novel prognostic signature from the training group using the least absolute shrinkage and selection operation (LASSO) and COX regression. Next, to verify the accuracy of the signature, we conducted risk and survival analysis, as well as the construction of ROC curve, nomogram, and calibration curves in the training group, test group, and all samples. Finally, the redox gene-redox-related lncRNA interaction network was constructed, and gene set enrichment analysis (GSEA) was performed to investigate the status of redox-related functions between high/low-risk groups. Results. A nine-redox-related lncRNA signature consisted of AC025580.3, COLCA1, AC027601.2, DLEU2, AC004918.3, AP006621.2, AL031670.1, SPINT1-AS1, and LAMA5-AS1 was significantly associated with overall survival in ccRCC patients. The signature proved efficient, and thus, a nomogram was successfully assembled. In addition, the GSEA results demonstrated that two major redox-related functions were enhanced in the high-risk group ccRCC patients. Conclusions. Our findings robustly demonstrate that the nine-redox-related lncRNA signature could serve as an efficient prognostic indicator for ccRCC.

Identification of an m6A-Related lncRNA Signature for Predicting the Prognosis in Patients With Kidney Renal Clear Cell Carcinoma

“…It gave us insight into their potential role in tumorigenesis and development for KIRC. Also, Xia et al (28) reported the prognostic role of AP006621.2 and AC025580.3 in KIRC. However, the roles of the remaining three m6A-related lncRNAs in tumors have not been reported.…”

A Metastasis-Related lncRNA Signature Correlates With the Prognosis in Clear Cell Renal Cell Carcinoma

“…TFPI2 is a matrix related serine protease inhibitor with a Kunitz domain, and plays an important role in angiogenesis, tumorigenesis and metastasis ( 17 , 18 ). As the most important factor in inducing EMT, TGF-β1 can promote the metastasis of various tumor cells ( 19 ). THBS2 is involved in many cellular biological processes by binding EMC protein and cell surface receptor ( 20 ).…”

SPINT1-AS1 Drives Cervical Cancer Progression via Repressing miR-214 Biogenesis

“…Previous reports about the clinical relevance of SPINT-AS1 in cancers are inconsistent. SPINT1-AS1 was reported to be associated with good prognosis of renal clear cell carcinoma ( Qi-Dong et al, 2020 ). SPINT1-AS1 was also reported to predict poor prognosis in colorectal cancer ( Li et al, 2018 ).…”
