MicroRNAs (miRNAs) represent a family of small noncoding RNAs with important regulatory roles in diverse biological processes ranging from cell differentiation to organism development. In chickens, the full set of miRNAs and the expression patterns of miRNAs during development are still poorly understood when compared to the other vertebrates. In this study, we identified 29 novel miRNAs and 140 potential...
In this study, we have determined the complete sequence of the mitochondrial genome of an Old World tree frog Polypedates megacephalus (Anura: Rhacophoridae) by using a long polymerase chain reaction (PCR) technique and shotgun strategy of sequencing. The entire mtDNA sequence is 16,473 nt long with a novel mitogenomic gene organization in amphibians. Unlike other neobatrachian frogs, the transfer...
By construction and screen of mouse nucleolar cDNA library, a novel mammalian small nucleolar RNAs (snoRNA) was identified. The novel snoRNA, 70 nt in length, displays structural features typical of C/D box snoRNA family. The snoRNA possesses an 11-nt-long rRNA antisence element and is predicted to guide the 2'-O-methylation of mouse 28S rRNA at G4043, a site unknown so far to be modified in vertebrates...
The mitochondrial genome of the Chinese giant salamander Andrias davidianus was isolated using the long-and-accurate polymerase chain reaction (LA PCR) method. The sequencing work adopted the shotgun strategy accompanying with seven internal primers to cover the gaps where overlapping clones were not available. The entire mtDNA sequence is 16,503 bp long, with a gene content of 13 protein-coding,...
