Long Non-Coding RNAs in Kidney Injury: A Comprehensive Review

Abstract

Kidney injury, a global health challenge, necessitates a nuanced understanding of molecular intricacies for effective interventions. Long non-coding RNAs (lncRNAs), once dismissed as transcriptional noise, now emerge as pivotal players in orchestrating renal health. Dysregulation of specific lncRNAs like TUG1, MALAT1, H19, and NEAT1 provides molecular signatures, distinguishing physiological states from pathological conditions. In acute kidney injury (AKI), TUG1 and MALAT1 regulate apoptosis, inflammation, and fibrosis. Chronic kidney disease (CKD) involves lncRNAs like H19 and NEAT1 modulating cell proliferation and apoptosis. Beyond diagnostics, lncRNAs actively shape inflammation, apoptosis, and fibrosis, positioning them as master regulators in the intricate ballet of kidney health. Recent strides in research, coupled with cutting-edge genomics and bioinformatics tools, highlight their roles and therapeutic potential. Challenges in understanding their intricate roles and interactions necessitate the exploration of promising avenues, including single-cell RNA sequencing and artificial intelligence, paving the way for personalized interventions and regenerative medicine in kidney diseases.
