| Abstract | Although great progresses have been made in the diagnosis and treatment of hepatocellular carcinoma (HCC), its prognostic marker remains controversial. In this current study, via weighted correlation network analysis (WGCNA) and Cox regression analysis on the database of HCC patients from The Cancer Genome Atlas (TCGA), we constructed a five autophagy-related long non-coding RNA (AR-lncRNA) prognostic signature for HCC. This signature includes TMCC1-AS1, PLBD1-AS1, MKLN1-AS, LINC01063, and CYTOR, all of which were highly expressed in the high-risk group of HCC patients. This five-AR-lncRNA prognostic signature showed good area under the curve (AUC) value (AUC = 0.751) for the overall survival (OS) prediction of all HCC patients. It also performed well in each stratified group of HCC patients classified by several clinical traits. We then used this five-AR-lncRNA prognostic signature to establish a good nomogram for the prediction of the 3- and 5-year OS outcomes of HCC patients intuitively (concordance index = 0.745). By parallel comparison, this five-AR-lncRNA signature has better prognosis accuracy than three recently published signatures. Furthermore, it also efficiently predicted the therapeutic outcomes of HCC patients, including chemotherapy and immunotherapeutic responses. Gene set enrichment analysis (GSEA) and gene mutation analysis revealed that dysregulated cell cycle pathway, purine metabolism and TP53 mutation may play an important role in determining the OS outcomes of HCC patients in the high-risk group. Collectively, our study suggests a new five-AR-lncRNA prognostic signature for HCC. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
