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.

Enhancing outcomes after surgery of breast cancer patients with miR-145

According to research results published online ahead of print in the Journal of the American College of Surgeons (JACS), microRNA (miRNA) can be used as a biomarker to identify which individuals are most likely to experience breast cancer recurrence and mortality.

Salivary miRNAs may be a promising biomarker for persistent post-concussive symptoms in children

Predicting clinical recovery of children with concussion is challenging. While concussion symptoms typically resolve within one to three weeks, up to one-third of children develop persistent post-concussive symptoms (PPCS), including headache, nausea, dizziness, blurred vision and sensitivity to light and/or sound.
