Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
To analyse roles of HAI-1/Spint1 in intestinal tumorigenesis, we examined the effect of intestine-specific deletion of Spint1 gene on Apc(Min/+) mice. The loss of Hai-1/Spint1 significantly accelerated tumor formation in ApcMin/+ mice and shortened their survival periods.
Publication Title
Hepatocyte growth factor activator inhibitor type 1 is a suppressor of intestinal tumorigenesis.

Description
To examine the role of hepatpcyte growth factor activator inhibitor type 1 (HAI-1) in cancer, we analyzed effect of HAI-1 silencing on gene expression profiles of human oral squamous cell carcinoma cell line, SAS. We used short hairpin RNA (shRNA) directed against HAI-1 mRNA. We constructed retroviral vectors which showed stable and significant silencing effects on HAI-1 genes of SAS.

Description
A growing body of evidence suggests that the vasoactive peptides endothelins (ETs) and their receptors (primarily the ETB receptor) are contributors to neurodegeneration in glaucoma. However, ETs actions in retinal ganglion cells (RGCs) are not fully understood. The purpose of this study was to determine ETs effects on gene expression in primary RGCs.

Description
We study differences in gene expression between Populus P35S::BL (BL-oe) lines and control, affecting plant growth and differentiation, and dormancy. We used microarrays to detail the global program of gene expression underlying morphological and developmental changes droved by overexpression of BL gene.

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
Schizophrenia and other psychiatric disorders are postulated to be developmental disorders resulting from synapse dysfunction. How susceptibility genes for major mental disorders could lead to synaptic deficits in humans is not well-understood. Here we generated induced pluripotent stem cells (iPSCs) from four members of a family in which a frame-shift mutation of Disrupted-in-schizophrenia-1 (DISC1) co-segregated with psychiatric disorders and further produced different isogenic iPSC lines via genetic editing. We showed that mutant DISC1 causes synaptic vesicle release deficits in iPSC-derived forebrain neurons. Mechanistically, mutant DISC1 dysregulates the expression of many genes related to synapses and psychiatric disorders and depletes wild-type DISC1 and the NCoR1 transcription co-repressor complex. Furthermore, mechanism-guided pharmacological inhibition of phosphodiesterases rescues synaptic defects in mutant neurons. Our study uncovers a novel gain-of-function mechanism through which the psychiatric disorder-relevant mutation affects synaptic functions via transcriptional dysregulation and provides insight into the molecular and synaptic etiopathology of psychiatric disorders. Overall design: Two patient derived iPSC lines carrying heterozygous 4bp deletion in DISC1 gene and 1 related control were analyzed in biological triplicate

Description
We study the effect of nitrogen limitation on the growth and development of poplar roots. We used microarrays to detail the global program of gene expression underlying morphological and developmental changes driven by low nitrogen in the growth media. We report the effect of nitrogen limitation on the growth and development of poplar roots. Low nitrogen concentration led to increased root elongation followed by lateral root proliferation and finally increased root biomass. These morphological responses correlated with high and specific activation of genes encoding regulators of cell cycle and enzymes involved in cell wall biogenesis, growth and remodeling. Comparative analysis of poplar and Arabidopsis root transcriptomes under nitrogen deficiency indicated many similarities and diversification in the response in the two species. A reconstruction of genetic regulatory network (GRN) analysis revealed a sub-network centered on a PtaNAC1-like transcription factor. Consistent with the GRN predictions, root-specific upregulation of PtaNAC1 in transgenic poplar plants increased root biomass and led to significant changes in the expression of the connected genes specifically under low nitrogen. PtaNAC1 and its regulatory miR164 showed inverse expression profiles during response to LN, suggesting of a micro RNA mediated attenuation of PtaNAC1 transcript abundance in response to nitrogen deprivation.
