| miR-195 is commonly downregulated and acts as a tumour suppressor. Reduced miR-195 can release inhibition of cell-cycle, survival, angiogenesis, EMT, and drug-resistance genes.
MicroRNA-195 (miR-195; commonly
miR-195-5p) is a small non-coding RNA belonging to the
miR-15/16/195/424/497 family. It regulates gene expression by binding target
messenger RNAs and promoting transcript degradation or translational
repression. In many cancers, miR-195 ↓ is the more
commonly reported pattern, and miR-195 generally functions as a
tumour-suppressive microRNA. Restoration or
miR-195 ↑ can inhibit cell-cycle progression,
proliferation, migration, invasion, angiogenesis, epithelial-mesenchymal
transition, and treatment resistance while promoting apoptosis in susceptible
cancer models. Reported targets include CCND1,
CCNE1, CDK4, CDK6,
E2F3, BCL2, BCL2L2,
BIRC5, VEGF, and
FGF2/bFGF.
