TranscriptomicsMicroRNA sequence and expression analysis in breast tumors by deep sequencing [miRNA sequence data]
MicroRNAs (miRNAs) regulate many genes critical for tumorigenesis. We profiled miRNAs from 11 normal breast tissues, 17 non-invasive, 151 invasive breast carcinomas, and 6 cell lines by in-house-developed barcoded Solexa sequencing. miRNAs were organized in genomic clusters representing promoter-con...

TranscriptomicsVariation in homeodomain DNA-binding revealed by high-resolution analysis of sequence preferences
Most homeodomains are unique within a genome, yet many are highly conserved across vast evolutionary distances, implying strong selection on their precise DNA-binding specificities. We determined the binding preferences of the majority (168) of mouse homeodomains to all possible 8-base sequences, re...

TranscriptomicsDeep Sequence Analysis of the Relationship between Gene Expression, CpG Island Methylation, and Gene Copy Number in Breast Cancer Cells
We used deep sequencinge technology to profile the transcriptome, gene copy number, and CpG island methylation status simultaneously in eight commonly used breast cell lines to develop a model for how these genomic features are integrated in estrogen receptor positive (ER+) and negative breast cance...

TranscriptomicsSubcellular RNA Sequencing Reveals Broad Presence of Cytoplasmic Intron-sequence Retaining Transcripts in Mouse and Rat Neurons.
Recent findings have revealed the complexity of the transcriptional landscape in mammalian cells. One recently described class of novel transcripts are the Cytoplasmic Intron-sequence Retaining Transcripts (CIRTs), hypothesized to confer post-transcriptional regulatory function. For instance, the ne...

TranscriptomicsThe anti-Shine-Dalgarno sequence drives translational pausing and codon choice in bacteria
Protein synthesis by ribosomes takes place on a linear substrate but at variable speeds. Transient pausing of ribosomes can impact a variety of co-translational processes, including protein targeting and folding. These pauses are influenced by the sequence of the mRNA. Thus redundancy in the genetic...

ProteomicsSequence coverage by multiple reads in shotgun proteomics to validate single amino acid variants
Mass spectrometry-based shotgun proteomics is currently based on assigning matches between mass-spectra of protein fragments resulting from protease digestion and amino acid sequences predicted from nucleic acid sequences. At the same time, the method lacks reliability in identification of every sin...

GenomicsConserved Function of lincRNAs in Vertebrate Embryonic Development Despite Rapid Sequence Evolution
Thousands of large intervening non-coding RNAs (lincRNAs) have been identified in mammals. To better understand the evolution and functions of these enigmatic RNAs, we used chromatin marks, poly(A)-site mapping and RNA-Seq data, to identify more than 550 distinct lincRNAs in zebrafish. Although thes...

TranscriptomicsIdentification of promoter sequence elements involved in specific recognition by the ?S subunit of bacterial RNA polymerase.
Promoter recognition by bacterial RNA polymerase is mediated by ? subunits, which assemble transiently to RNA polymerase core enzyme (E) during transcription initiation. ? subunits drive transcription of specific sets of genes by allowing RNA polymerase to interact with different promoter sequences....
