MicroRNA Regulation

Meaning

MicroRNA Regulation refers to the critical biological process where small, non-coding RNA molecules, typically 19–25 nucleotides in length, modulate gene expression by binding to messenger RNA (mRNA) molecules, thereby inhibiting their translation into proteins or promoting their degradation. This fine-tuning mechanism is essential for controlling cellular differentiation, metabolism, and the stress response, acting as a powerful post-transcriptional regulator in nearly all physiological processes. Dysregulation is frequently implicated in hormonal disorders and aging.
