Abstract

Abstract: Aerobic glycolysis is a common metabolic phenotype in tumors that helps cancer cells adjust to severe living conditions and can aid metastasis in several types of carcinomas, including colorectal cancer (CRC). Long non‐coding RNAs (lncRNAs) can influence tumor biology and have been previously used to assess patients' outcomes and to identify potential therapeutic targets. However, despite the importance of glycolysis‐related lncRNAs (GRLs) in the development of CRC, studies on their use as prognostic markers are still limited. Herein, we applied a series of bioinformatic analyses to screen potential prognostic lncRNAs for colorectal cancer. Out of all lncRNAs screened, nine GRLs were selected to constitute a prognostic signature. Based on the signature, two molecular subtypes were classified with distinct prognostic outcomes and excellent diagnostic accuracy (The 1‐, 3‐ and 5‐year AUC are 0.756, 0.716, and 0.721, respectively). The prognostic value of this signature was further validated using another cohort. The enriched molecular pathways, immune infiltration, and mutation landscape were also significantly different between the two groups. The different drug sensitivity results between the two groups suggest a potential strategy for precise treatment. Furthermore, we confirmed that AFAP1‐AS1 could regulate aerobic glycolysis and metastasis of CRC cells. Overall, we developed a glycolysis‐related lncRNA (GRL) signature and suggested that this signature could offer a predictive value and identify potential therapeutic targets for cancer therapy. Abstract : In this article, a glycolysis‐related lncRNA signature was constructed in colorectal cancer and this signature is correlated with patients' survival and clinicopathological features. Furthermore, the relevant signalling pathways and immune infiltration landscape as identified by our model may pave the way for new therapeutic strategies for CRC. Finally, we demonstrated that AFAP1‐AS1 could regulate aerobic glycolysis and be a promising target in CRC.
