Lack of miR-1246 in small extracellular vesicle blunts tumorigenesis of laryngeal carcinoma cells by regulating Cyclin G2.

abstract：:Nucleotides of transfer RNAs (tRNAs) are highly modified, particularly at the anticodon. Bacterial tRNAs that read A-ending codons are especially notable. The U34 nucleotide canonically present in these tRNAs is modified by a wide range of complex chemical constituents. An additional two A-ending codons are not read b...

abstract：:Transfer RNAs require essential maturation steps to become functional. Among them, RNase P removes 5' leader sequences of pre-tRNAs. Although RNase P was long thought to occur universally as ribonucleoproteins, different types of protein-only RNase P enzymes were discovered in both eukaryotes and prokaryotes. Interest...
