Abstract:
Recent advances in obesity research have shifted focus toward biological mechanisms, paralleling progress in pharmacotherapy. Fat browning-the conversion of white to brown adipocytes-emerges as a promising therapeutic strategy. Circular RNAs (circRNAs), stable non-coding RNAs with regulatory functions, are now recognized as key modulators of this process through organelle-mediated mechanisms. This review synthesizes current understanding of circRNA biogenesis and their roles in fat browning, particularly their interactions with mitochondria and endoplasmic reticulum in lipid metabolism. We highlight their capacity to encode peptides and regulate metabolic pathways, positioning circRNAs as potential precision therapeutics. While preclinical studies demonstrate mechanistic efficacy, clinical translation requires addressing delivery challenges and tissue-specific effects. This biological perspective advances obesity treatment paradigms beyond simplistic energy-balance models, mirroring the evolution seen in pharmacotherapeutic development.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
