microRNA expression

microRNA expression predicts chronological age estimation in humans.

“MicroRNAs represent a promising class of molecular biomarkers for forensic age estimation due to their stability, tissue specificity, and age-associated expression patterns.”

sex is associated with microRNA expression in rats (65 miRNAs (FDR <5%, ≥1.5-fold change)).

“65 and 212 miRNAs showed significant (false discovery rate (FDR) <5% and ≥1.5-fold change) sex- and age-related differences in expression, respectively.”
