Roles and regulatory mechanisms of miR-30b in cancer, cardiovascular disease, and metabolic disorders (Review)

MicroRNAs (miRNAs) are non-coding RNAs 21-23 nucleotides in length that regulate gene expression, and thereby modulate signaling pathways and protein synthesis in both physiological and pathogenic processes. miR-30b inhibits cell proliferation, migration, invasion and epithelial-mesenchymal transformation in multiple types of cancer. In addition to its role in several types of neoplasias, miR-30b has been shown to exhibit essential roles in cardiovascular and metabolic diseases. In the present review, an overview of the biological functions of miR-30b and its role in the pathogenesis of neoplastic, cardiovascular and metabolic diseases is provided. miR-30b is a potential candidate for clinical development as a diagnostic and prognostic biomarker, therapeutic agent and drug target. However, further research is required to elucidate its role in health and disease and to harness its potential clinical utility.

Automated summary

miR-30b, a 21-23 nucleotide long non-coding RNA, has been shown to inhibit cell proliferation, migration, invasion and epithelial-mesenchymal transformation in various types of cancer, as well as play essential roles in cardiovascular and metabolic diseases. It is considered a potential candidate for clinical development as a diagnostic and prognostic biomarker, therapeutic agent and drug target, although further research is needed to fully understand its role in health and disease.
