Description
Smad2/3 are transcription factors that engage in TGF-beta-induced transcription. We determined and analyzed HepG2 and Hep3B-specific Smad2/3 binding sites by ChIP-chip. We used expression microarrays to compare the Smad2/3 and HNF4alpha binding sites identified by ChIP-chip or ChIP-seq, respectively, to TGF-beta-induced gene expressions.

Description
Placental development is a key event in mammalian reproduction and embryogenesis. However, the molecular basis underlying extraembryonic lineage specification and subsequent placental development is not fully understood. Through a genetic screen, we identified Zfp281 as a key factor for extraembryonic development. Disruption of Zfp281 in mice caused severe defects in extraembryonic as well as embryonic tissues. Importantly, Zfp281 was preferentially expressed in the trophoblast stem cell population in an FGF-dependent manner and ensured the expression of genes necessary for placental development. Through the analysis of transcriptome and epigenome, we identified Zfp281 as an important factor to shape the transcriptome of mammalian trophoblast stem cells. Overall design: To study the role of Zfp281 in transcriptional regulation, we performed RNA-seq using mouse and human TS cells. Furthermore, we performed H3K4me3 ChIP-seq and ATAC-seq to reveal the roles of Zfp281 in chromatin regulation.

Description
The differentiation of preadipocytes into adipocytes is controlled by several transcription factors, including peroxisome proliferator-activated receptor (PPAR) and CCAAT/enhancer-binding protein (C/EBP), which are known as master regulators of adipogenesis. BCL11B is a zinc finger-type transcription factor that regulates the development of the skin and central nervous and immune systems. Here, we found that BCL11B was expressed in the white adipose tissue (WAT), particularly the subcutaneous WAT and that BCL11B/ mice had a reduced amount of subcutaneous WAT. During adipogenesis, BCL11B expression transiently increased in 3T3-L1 preadipocytes and mouse embryonic fibroblasts (MEFs). The ability for adipogenesis was reduced in BCL11B knockdown 3T3-L1 cells and BCL11B/ MEFs, whereas the ability for osteoblastogenesis was unaffected in BCL11B/ MEFs. Luciferase reporter gene assays revealed that BCL11B stimulated C/EBP activity. Furthermore, the expression of downstream genes of the Wnt/-catenin signaling pathway was not suppressed in BCL11B/ MEFs during adipogenesis. Thus, this study identifies BCL11B as a novel regulator of adipogenesis, which works, at least in part, by stimulating C/EBP activity and suppressing the Wnt/-catenin signaling pathway.

Description
Transcription termination and mRNA export from the nucleus are closely regulated and coordinated processes. Nuclear export factors are recruited to actively transcribed genes through their interactions with protein complexes associated with transcription and co-transcriptional pre-mRNA processing. We determine a new role for the kinase WNK1 in the cross-talk of transcription termination and mRNA export. WNK1 was previously attributed a cytoplasmic role as a regulator of ion transport. However, we now show a nuclear function for this kinase where it is required for efficient mRNA export along with the transcription termination factor PCF11. Finally, we identify the phosphorylation of the CID domain of PCF11 as an important step for the release of the mRNA from the transcription locus, thus allowing efficient mRNA export to the cytoplasm. Overall design: RNA from cytoplasmic and nuclear extracts of HeLa cells was obtained, upon depletion of WNK1 kinase or from control cells. Upon pA selection, libraries were generated and sequenced. A duplicate experiment was performed for each sample.

In other to assess functional involvement of Klf5 in DR regulation, we made liver-specific Klf5 knockout mice. Ductular reaction upon cholestatic liver injury is severely suppressed in these mice. We conducted RNA-seq analysis on the BECs from control mice and Klf5 LKO mice upon DDC injury to further elucidate the Klf5 functions. Overall design: Single-end RNA-seq of total RNAs extracted from BECs of Klf5 LKO mice upon DDC injury for 1wk

The transcription factor Klf5 is essential for intrahepatic biliary epithelial tissue remodeling after cholestatic liver injury.

Description
The pervasive nature of RNA polymerase II (Pol II) transcription requires efficient termination. A key player in this process is the cleavage and polyadenylation (CPA) factor PCF11, which directly binds to the Pol II C-terminal domain and dismantles elongating Pol II from DNA in vitro. We demonstrate that PCF11-mediated termination is essential for vertebrate development. A range of genomic analyses, including: mNET-seq, 3' mRNA-seq, chromatin RNA-seq and ChIP-seq, reveals that PCF11 enhances transcription termination and stimulates early polyadenylation genome-wide. PCF11 binds preferentially between closely spaced genes, where it prevents transcriptional interference and downstream gene silencing. Notably, PCF11 is sub-stoichiometric to the CPA complex. Low levels of PCF11 are maintained by an auto-regulatory mechanism involving premature termination of its own transcript, and are important for normal development. Both in human cell culture and during zebrafish development, PCF11 selectively attenuates the expression of other transcriptional regulators by premature CPA and termination. Overall design: Semi-nascent transcriptome measured by chromatin-bound RNA-seq in HeLa cells. Control and PCF11 knock-down (2 biological replicates) and control and PCF11 PAS1 deletion (4 biological replicates).

Overall design: 3' mRNA-seq in individual zebrafish embryo heads. Two types of mutants: zPCF11 null and zPCF11 with deletion of PAS1. Wild-type (wt, +/+), heterozygous (het, +/-) and homozygous mutant (hom, -/-) embryos were analyzed. Wild-type and heterozygous animals were phenotypically indistinguishable.
