TranscriptomicsRNA-seq analysis in Cornea epithelial cells (CECs), skin epithelial cells (SECs), LSCs after knocking down PAX6 (3-D shPAX6 LSCs) and SESCs transduced with PAX6(3-D PAX6+ SESCs) upon 3-D differentiation
Purpose: We find that Wnt7a-PAX6 axis determine corneal epithelial cell fate. To obtain global evidence for successful cell fate conversion, we performed gene expression profiling by RNA-seq on CECs, SECs, and LSCs after knocking down PAX6 and on SESCs transduced with PAX6 upon 3-D differentiation. ...

TranscriptomicsEffects of Cardiac Glycosides on RNA Expression in Prostate Cancer LNCaP-abl Cells
Prostate cancer is the most common cancer in men and cardiac glycosides inhibit prostate cancer cell proliferation. In order to investigate the mechanism by which cardiac glycosides inhibit prostate cancer cells, we observed genome-wide RNA expression in prostate cancer LNCaP-abl cells, hormone res...

TranscriptomicsALS-causative mutations in FUS/TLS confer gain- and loss-of-function by altered association with SMN and U1-snRNP
The RNA-binding protein FUS/TLS, mutation in which is causative of the fatal motor neuron disease ALS, is demonstrated to directly bind to the U1-snRNP and SMN complexes. ALS-causative mutations in FUS/TLS are shown to abnormally enhance their interaction with SMN and reduce interaction with U1-snRN...

TranscriptomicsNuclear Matrix Factor hnRNP U/SAF-A Exerts a Global Control of Alternative Splicing by Regulating U2 snRNP Maturation
The nuclear matrix associated hnRNP U/SAF-A protein has been implicated in diverse pathways from transcriptional regulation to telomere length control to X inactivation, but the precise mechanism underlying each of these processes has remained elusive. Here, we report hnRNP U as a regulator of SM...

TranscriptomicsSR Proteins Collaborate with 7SK and Promoter-Associated Nascent RNA to Release Paused Polymerase
RNAP II is frequently paused near gene promoters in mammals and its transition to productive elongation requires active recruitment of P-TEFb, a cyclin-dependent kinase for RNAP II and other key transcription elongation factors. A fraction of P-TEFb is sequestered in an inhibitory complex containing...

TranscriptomicsRBFox2 regulates a broad RNA program and is required for genome-wide targeting of polycomb complex
Increasing evidence suggests that diverse RNA binding proteins interact with regulatory RNAs to regulate transcription. RBFox2 is a ubiquitous RNA binding protein with prevalent expression in stem cells, heart, and brain. Here, we report a systematic dissection of the RBFox2-regulated RNA program in...

TranscriptomicsThe Akt-SRPK-SR axis constitutes a major pathway in transducing EGF signaling to regulate alternative splicing in the nucleus
Pre-mRNA splicing is regulated by developmental and environmental cues, but little is known about how specific signals are transduced in mammalian cells to regulate this critical gene expression step. Here, we report massive reprogramming of alternative splicing in response to EGF signaling. By blo...

TranscriptomicsGenome-wide Analysis Reveals SR Protein Cooperation and Competition in Regulated Splicing
SR proteins are well-characterized RNA binding proteins that promote exon inclusion by binding to exonic splicing enhancers (ESEs). However, it has been unclear whether regulatory rules deduced on model genes apply generally to activities of SR proteins in the cell. Here, we report global analyses o...

TranscriptomicsMechanisms for U2AF to define 3M-bM-^@M-2 splice sites and regulate alternative splicing in the human genome
The U2AF heterodimer has been well studied for its role in defining functional 3M-bM-^@M-^Y splice sites in pre-mRNA splicing, but many fundamental questions still remain unaddressed regarding the function of U2AF in mammalian genomes. Through genome-wide analysis of U2AF-RNA interactions, we report...

TranscriptomicsMolecular Determinants for RNA Polymerase II Elongation Rate and Acceleration
Recent studies reveal a striking phenomenon that RNA Polymerase II (Pol II) appears to travel on gene body in an accelerated fashion, but the mechanism has remained unknown. We performed synchronized transcription coupled with deep sequencing, observing an inverse relationship between initial rate ...
