Micro RNAs (miRNAs) have recently emerged as key regulators of metabolic processes! . More and more evidence is accumulating that suggest that the dysregulation of miRNAs may contribute to metabolic abnormalities such as the misregulation of cholesterol and lipid metabolism, insulin… Read More ›
Piwi-RNA
The 3′ termini of mouse Piwi RNAs are 2′-O-methylated
Kirino & Mourelatos and Ohara et al. showed in 2007 that Piwi RNAs (piRNAs) are 2′-O-methylated at the 3′-end Several thousands of piwi RNA (piRNA) species that are typically 24–32 nucleotide (nt) long have been found in mammals, zebrafish, and… Read More ›
Piwi-RNAs, the Defenders of the Genome
What are Piwi- or piRNAs ? Here is the answer: P-element induced wimpy testis (Piwi)-RNAs, or Piwi-interacting RNA, or piRNAs are small RNAs typically 23 to 35 nucleotides long . . During the recent 16 years a group of small… Read More ›
