Illumina HiSeq 2500
Description
Cohesinopathies are characterized by mutations in the cohesin complex. Mutations in NIPBL, a cohesin loader, result in Cornelia de Lange syndrome (CdLS). CdLS is a congenital genetic disorder distinguished by craniofacial dysmorphism, abnormal upper limb development, delayed growth, severe cognitive retardation, and multiple organ malformations.It has been suggested that CdLS is caused by defects in the cohesin network that alter gene expression and genome organization. However, the precise molecular etiology of CdLS is largely unclear. To gain insights, we sequenced mRNAs isolated from mouse embryonic fibroblasts of both WT and NIPBL-haploinsufficient mice and compared their transcriptomes. Overall design: Examination of gene expression of WT and NIPBL+/- mice by RNA-seq

- Illumina HiSeq 2500
Description
Condensin complexes are highly conserved for chromosome compaction to ensure their faithful segregation in mitosis. Condensin II is present in the nucleus throughout the cell cycle, including interphase. The aim of these experiments is to investigate the changes of gene expression in knockdown of NCAPH2, a condensin II subunit, in mouse embryonic stem cells compared to their control cells. Overall design: Examination of gene expression of controls and NCAPH2 knockdown cells by RNA-seq
Publication Title
Condensin II is anchored by TFIIIC and H3K4me3 in the mammalian genome and supports the expression of active dense gene clusters.

Description
Salt stress is one of the most severe environmental conditions which cause huge losses in crop production worldwide. We identified a novel calcium-binding protein and used the Affymetrix whole-genome arrays to define downstream targets of this important protein.
Publication Title

Description
We investigated the occupancy of RNA PolII and INTS11 during the stimulation of EGF and compared with drug treated condition using inhibitors against MAPK pathway and Integrator. Additionally, we examined transcription by sequencing the chromatin-bound fraction of RNA. Overall design: We employed several cel lines in our experiment, including HELA, KRAS mutant lung cancer cell line A549 and BRAF mutatant melanoma cell line A375. The conditons we checked including EGF stimulation, MAPK pathway inhibition using BRAF, MEK or ERK inhibitiors, targeting INTS11 with RNAi or integrator inhibitor. We used RNA sequencing to measure the expression profile and CHIP sequencing to detect INTS11 and RNA PolII recruitment on chromatin.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
The observation that Tcf3 (MGI name: Tcf7l1) bound the same genes as core stem cell transcription factors, Oct4 (MGI name:Pou5f1), Sox2 and Nanog, revealed a potentially important aspect of the poorly understood mechanism whereby Wnts stimulate self renewal of pluripotent mouse embryonic stem (ES) cells. Although the conventional view of Tcf proteins as the -catenin-binding effectors of Wnt signaling suggested Tcf3 should activate target genes in response to Wnts, here we show that Wnt3a and Tcf3 effectively antagonize each others effects on gene expression. Genetic ablation of Tcf3 caused similar effects as treating cells with recombinant Wnt3a.

Opposing effects of Tcf3 and Tcf1 control Wnt stimulation of embryonic stem cell self-renewal.

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Identifying the early gene program induced by GnRH would help understand how GnRH-activated signaling pathways modulate gonadotrope secretory response. We previously analyzed GnRH-induced early genes in LbT2 cells, however these lack GnRH self-potentiation, a physiological attribute of gonadotropes. To minimize cellular heterogeneity, rat primary pituitary cultures were enriched for gonadotropes by 40-60% using a sedimentation gradient. Given the limited number of gonadotropes, RNA was amplified prior to microarray analysis. Thirty-three genes were up-regulated 40 minutes after GnRH stimulation. Real-time PCR confirmed regulation of several transcripts including fosB, c-fos, egr-2 and rap1b, a small GTPase and member of the Ras family. GnRH stimulated rap1b gene expression in gonadotropes, measured by a sensitive single cell assay. Immunocytochemistry revealed increased Rap1 protein in GnRH-stimulated gonadotropes. These data establish rap1b as a novel gene rapidly induced by GnRH and a candidate to modulate gonadotropin secretion in rat gonadotropes.
Publication Title
Optimized amplification and single-cell analysis identify GnRH-mediated activation of Rap1b in primary rat gonadotropes.

Description
Neuropathic pain (NP) is caused by primary or secondary impairment of the peripheral or central nervous systems. Its etiology is complex and involves abnormal patterns of gene expression and pathway activation. Using bioinformatic analysis, we aimed to identify NP-associated changes in genes and pathways in L4 and L5 dorsal root ganglia (DRG) in a rat model of NP induced by chronic compression of the DRG (CCD).
