MicroRNAs (miRNAs) are small noncoding RNAs which repress gene expression at the posttranscriptional level. In this study, an expressed sequence tag (EST)-based combined method was applied for the detection of miRNAs inMacaca fasciculariswhich is used as a model animal extensively in medical experiments, particularly those involved with neuroscience and disease. Initially, previously known miRNA sequences from metazoans were used to blast with the EST databases ofMacaca fascicularis, and then a range of filtering criteria was conducted to remove some pseudo ones. At last a total of 8 novel conserved miRNAs were identified; their functions were further predicted and analyzed. Together, our study provides insight into miRNAs and their functions inMacaca fascicularis, indicating that the EST analysis is an efficient and affordable alternative approach for identifying novel miRNA candidates.

Noncoding RNAs (ncRNAs) have been identified in many fungi. However, no genome-scale identification of ncRNAs has been inventoried for basidiomycetes. In this research, we detected 254 small noncoding RNAs (sncRNAs) in a genome assembly of an isolate (CCEF00389) ofPleurotus ostreatus, which is a widely cultivated edible basidiomycetous fungus worldwide. The identified sncRNAs include snRNAs, snoRNAs, tRNAs, and miRNAs. SnRNA U1 was not found in CCEF00389 genome assembly and some other basidiomycetous genomes by BLASTn. This implies that if snRNA U1 of basidiomycetes exists, it has a sequence that varies significantly from other organisms. By analyzing the distribution of sncRNA loci, we found that snRNAs and most tRNAs (88.6%) were located in pseudo-UTR regions, while miRNAs are commonly found in introns. To analyze the evolutionary conservation of the sncRNAs inP. ostreatus, we aligned all 254 sncRNAs to the genome assemblies of some other Agaricomycotina fungi. The results suggest that most sncRNAs (77.56%) were highly conserved inP. ostreatus, and 20% were conserved in Agaricomycotina fungi. These findings indicate that most sncRNAs ofP. ostreatuswere not conserved across Agaricomycotina fungi.

A novel Theta class glutathione transferase (GST) isoenzyme from mouse termed mGSTT3 has been identified by analysis of the expressed sequence tag database. The gene encoding mGSTT3 is clustered with the mGSTT1 and mGSTT2 genes on chromosome 10 and has an exon/intron structure that is similar to that of the other Theta class genes. mGSTT3 is expressed strongly in the liver and to a decreasing extent in the kidney and testis. Recombinant mGSTT3-3 expressed in Escherichia coli had a substrate-specificity profile that differed significantly from that of GSTT1-1 and GSTT2-2 isoenzymes. A molecular model of mGSTT3 suggested that, in comparison with GSTT2, a decrease in volume of the hydrophobic substrate-binding site and the loss of the sulphate-binding pocket prevents its use of the GSTT2 substrate 1-menaphthyl sulphate.
