Comprehensive identification of miRNA target sites in live animals.
Methods in molecular biology (Clifton, N.J.) · 2011 · 732: 169-85
MicroRNAs (miRNAs) are small RNA molecules that posttranscriptionally regulate the expression of protein-coding genes. The mature miRNAs are loaded into Argonaute-containing protein complexes (miRISC, miRNA Induced S ilencing Complex), and guide these complexes to the 3' UTR of targeted mRNA …

Genome-wide approaches in the study of microRNA biology.
Wiley interdisciplinary reviews. Systems biology and medicine · 2011 · 3(5): 491-512
MicroRNAs (miRNAs), a class of ∼21-23 nucleotide long non-coding RNAs (ncRNAs), have critical roles in diverse biological processes that encompass development, proliferation, apoptosis, stress response, and fat metabolism. miRNAs recognize their target mRNA transcripts by partial sequence complementarity and collectively …

RNA-seq analysis of gene expression and alternative splicing by double-random priming strategy.
Methods in molecular biology (Clifton, N.J.) · 2011 · 729: 247-55
Transcriptome analysis by deep sequencing, more commonly known as RNA-seq is, becoming the method of choice for gene discovery and quantitative splicing detection. We published a double-random priming RNA-seq approach capable of generating strand-specific information [Li et al., Proc Natl …

Comprehensive discovery of endogenous Argonaute binding sites in Caenorhabditis elegans.
Nature structural & molecular biology · 2010 · 17(2): 173-9
MicroRNAs (miRNAs) regulate gene expression by guiding Argonaute proteins to specific target mRNA sequences. Identification of bona fide miRNA target sites in animals is challenging because of uncertainties regarding the base-pairing requirements between miRNA and target as well as the …

An RNA code for the FOX2 splicing regulator revealed by mapping RNA-protein interactions in stem cells.
Nature structural & molecular biology · 2009 · 16(2): 130-7
The elucidation of a code for regulated splicing has been a long-standing goal in understanding the control of post-transcriptional gene expression events that are crucial for cell survival, differentiation and development. We decoded functional RNA elements in vivo by constructing …

Determination of tag density required for digital transcriptome analysis: application to an androgen-sensitive prostate cancer model.
Proceedings of the National Academy of Sciences of the United States of America · 2008 · 105(51): 20179-84
High-throughput sequencing has rapidly gained popularity for transcriptome analysis in mammalian cells because of its ability to generate digital and quantitative information on annotated genes and to detect transcripts and mRNA isoforms. Here, we described a double-random priming method for …

Divergent transcription from active promoters.
Science (New York, N.Y.) · 2008 · 322(5909): 1849-51
Transcription initiation by RNA polymerase II (RNAPII) is thought to occur unidirectionally from most genes. Here, we present evidence of widespread divergent transcription at protein-encoding gene promoters. Transcription start site-associated RNAs (TSSa-RNAs) nonrandomly flank active promoters, with peaks of antisense …

The PIWI proteins SMEDWI-2 and SMEDWI-3 are required for stem cell function and piRNA expression in planarians.
RNA (New York, N.Y.) · 2008 · 14(6): 1174-86
PIWI proteins are expressed in germ cells in a wide variety of metazoans, where they participate in the synthesis and function of a novel class of small RNAs called PIWI associated RNAs (piRNAs). One function of piRNAs is to preserve …

Multiple layers of molecular controls modulate self-renewal and neuronal lineage specification of embryonic stem cells.
Human molecular genetics · 2008 · 17(R1): R67-75
Elucidating the molecular changes that arise during neural differentiation and fate specification is crucial for building accurate in vitro models of neurodegenerative diseases using human embryonic stem cells (hESCs). Here we review the importance of hESCs and derived progenitors in …

A regulator of Dscam mutually exclusive splicing fidelity.
Nature structural & molecular biology · 2007 · 14(12): 1134-40
The Down syndrome cell adhesion molecule (Dscam) gene has essential roles in neural wiring and pathogen recognition in Drosophila melanogaster. Dscam encodes 38,016 distinct isoforms via extensive alternative splicing. The 95 alternative exons in Dscam are organized into clusters that …

Alternative splicing events identified in human embryonic stem cells and neural progenitors.
PLoS computational biology · 2007 · 3(10): 1951-67
Human embryonic stem cells (hESCs) and neural progenitor (NP) cells are excellent models for recapitulating early neuronal development in vitro, and are key to establishing strategies for the treatment of degenerative disorders. While much effort had been undertaken to analyze …

Discovery and analysis of evolutionarily conserved intronic splicing regulatory elements.
PLoS genetics · 2007 · 3(5): e85
Knowledge of the functional cis-regulatory elements that regulate constitutive and alternative pre-mRNA splicing is fundamental for biology and medicine. Here we undertook a genome-wide comparative genomics approach using available mammalian genomes to identify conserved intronic splicing regulatory elements (ISREs). Our …

Identification and analysis of alternative splicing events conserved in human and mouse.
Proceedings of the National Academy of Sciences of the United States of America · 2005 · 102(8): 2850-5
Alternative pre-mRNA splicing affects a majority of human genes and plays important roles in development and disease. Alternative splicing (AS) events conserved since the divergence of human and mouse are likely of primary biological importance, but relatively few of such …
