| Abstract | Background Ferroptosis was involved in the pathogenesis of intervertebral disc degeneration (IVDD). However, the exact mechanism of IVDD associated with ferroptosis still required deeper studies. Method The differentially expressed genes (DEGs) in rat lumbar disc tissue between the control and IVDD group treated with IL-1β were detected by RNA sequencing (RNA-seq). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis were performed on DEGs. We further screened the differential expressed ferroptosis-related genes (DEFRGs). Besides, a protein-protein interaction (PPI) network of DEFRGs was constructed by STRING database. The Cytoscape database identified significant modules and the hub genes. The loss function of PDK4 by siRNA inference was investigated in NPCs by CCK8 assay, ELISA assay, and the analysis of ferroptosis indicators. Result DEGs were identified using RNA-seq. KEGG pathway analysis showed that these genes were mainly involved in Parkinson’s disease, oxytocin signaling pathway, calcium ion signaling pathway, AMPK signaling pathway, and glucagon signaling pathway. Eight hub genes (including LDHA, PKM, EP300, EGFR, EGLN1, SCD, PDK4, and FABP4) were found by the PPI network and Cytoscape on a total of 25 ferroptosis-related genes that were identified in rat lumbar disc tissue after IVDD treatment. PDK4 silencing promoted NPCS proliferation, decreased the levels of the proinflammatory factors, and suppressed ferroptosis. Conclusion The study suggested the potential roles of ferroptosis-related genes in IVDD and further revealed the role of PDK4 in the progression of IVDD. |

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.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
