miR-194 is a small, non-coding RNA enriched in epithelial tissues (notably liver, intestine, and kidney). Its physiologic role is to reinforce epithelial differentiation by repressing transcripts that drive motility, EMT, and stemness.
-Commonly DOWNREGULATED in many solid tumors during progression.
-Loss of miR-194 facilitates EMT, invasion, metastasis, and therapy resistance.
miR-194 is a tumor-suppressive microRNA whose loss marks transition toward EMT, invasion, and metastatic competence. As a biomarker, it is best used to interpret tumor state and risk—especially differentiation versus plasticity—rather than to diagnose cancer or choose a specific therapy.br
