MicroRNA News and Research

RSS

In genetics, microRNAs (miRNA) are single-stranded RNA molecules of 21-23 nucleotides in length, which regulate gene expression. miRNAs are encoded by genes from whose DNA they are transcribed but miRNAs are not translated into protein (i.e. they are non-coding RNAs); instead each primary transcript (a pri-miRNA) is processed into a short stem-loop structure called a pre-miRNA and finally into a functional miRNA. Mature miRNA molecules are partially complementary to one or more messenger RNA (mRNA) molecules, and their main function is to down-regulate gene expression.

Small non-coding RNA molecule precisely controls vital gene expression and cellular balance

A rapidly advancing area of biomedical innovation is shining a spotlight on miR-128-3p, a small yet powerful molecule with the potential to reshape how diseases—especially cancer—are detected, monitored, and treated. This microRNA, part of a broader class of non-coding RNAs, plays a critical role in regulating gene activity and maintaining cellular homeostasis.

Targeting microRNA communication reverses pancreatic cancer's immune suppression

In a unique finding, researchers at Georgetown's Lombardi Comprehensive Cancer Center discovered that when pancreatic cancer cells send out tiny particles that are packed with certain microRNA molecules, nearby immune cells called macrophages are reprogrammed to help the tumor grow instead of engaging in their regular role of fighting the tumor.
