In silico analysis of a MicroRNA regulatory network Influencing mitochondrial fission in hepatocellular carcinoma

Year: 2025

Type: article

Abstract: MicroRNAs (miRNAs), small non-coding RNA molecules known for their gene regulatory functions, are increasingly recognized to target genes critical for mitochondrial function in hepatocellular carcinoma (HCC). By employing in silico analysis this research investigates the underexplored involvement of a network of microRNAs in regulating mitochondrial fission within the context of HCC. We constructed a novel regulatory network, identifying hsa-miR-138-5p as a central regulator targeting key mitochondrial genes. Furthermore, we identified druggable binding pockets on the transcription factors WDR5 and HNF4, which regulate hsa-miR-138-5p. Molecular docking studies demonstrated favorable binding affinities of FDA-approved HCC drugs (sorafenib, lenvatinib, and regorafenib) to these binding pockets, suggesting an off-target mechanism by which these drugs might influence mitochondrial function through the hsa-miR-138-5p pathway. These findings contribute to the growing understanding of miRNA-mediated regulation in HCC and offer a foundation for developing novel microRNA-targeting drugs to modulate mitochondrial dynamics to manage HCC progression.
