By deep-transcript digital counting, 80% of H3K4me3 and 36% of comodified promoters were found to be transcribed.
In order to decipher hernandulcin biosynthesis, deep transcript sequencings (454 and Illumina) were performed, which facilitated the molecular cloning of five new sesquiterpene synthase cDNAs from L. dulcis.
The central aim of this project was to obtain deep transcript coverage of X. maculatus Jp 163 A. Therefore we utilized adult male and female whole animals as the RNA source for these studies.
Compared with EST technologies, MPSS involves deep transcript sampling and sequencing, usually 1-2 million transcripts per library, of a cDNA library on microbeads [ 29].
Deep transcript sequencing followed by in silico predictions and mass spectral analysis enabled the identification of numerous molluscan genes in this snail, including previously unknown neuropeptides.
For the dual-tag-based methods two four-base cutter restriction enzymes, DpnII and NlaIII, were used as initiation sites for the 21-nt sequences, and therefore deep transcript counts were obtained from fewer sites in the transcripts.
The establishment of tandem mass spectra derived from predicted peptides represented in the deep transcript database facilitated the empirical identification of a large number of corresponding proteins fractionated by one-dimensional SDS-PAGE.
Peaks span wider in protein-coding genes and deep sequencing transcripts [40] than in intergenic regions or the few introns in yeast.
The combination of deep sequencing, transcript and protein analysis combined would ensure the detection of LKB1 inactivation in tumours, however, this may not be the most practical route for clinical application.
To provide deeper coverage of transcripts encoding proteins functioning in olfaction, central nervous system-mediated behaviors, and male reproduction, sex-specific antennae, heads, and male accessory glands were dissected and stored at −20 °C in RNALater (Ambion/Life Technologies, Carlsbad, CA).
