Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
CFU-PreB colonies are reduced in number and size in Hspa9+/- mice compared to wildtype littermates. We compared the expression profiles of these colonies to gain insight into the mechanism driving this difference.
Publication Title
Reduced levels of Hspa9 attenuate Stat5 activation in mouse B cells.

Description
Myelodysplastic syndromes (MDS) are a heterogenous group of hematopoietic stem cell disorders characterized by dysplastic blood cell formation and peripheral blood cytopenias. Up to 30% of patients with MDS will progress to a highly chemotherapy-resistant secondary acute myeloid leukemia (sAML). We identified mutations in U2AF1 in MDS patients and patients with U2AF1 mutations are at an increased risk of developing sAML.
Publication Title
Recurrent mutations in the U2AF1 splicing factor in myelodysplastic syndromes.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
There is an association between transcriptome and the exercise-related phenotype. Peripheral blood cells suffer alterations in the gene expression pattern in response to perturbations caused by exercise. The acute response to endurance activates stress and inflammation, as well as growth and tissue repair responses.
Publication Title
PBMCs express a transcriptome signature predictor of oxygen uptake responsiveness to endurance exercise training in men.

Description
A limited number of growth factors are capable of regulating numerous developmental processes, but how they accomplish this is unclear. In the gustatory system, brain-derived neurotrophic factor (BDNF) and neurotrophin-4 (NT4) have different developmental roles but exert their effects through the same receptors (TrkB and p75).
Publication Title
BDNF and NT4 play interchangeable roles in gustatory development.

Description
BRAF inhibitors are highly effective therapies for patients with BRAF V600 mutated metastatic melanoma. Patients who receive BRAF inhibitors develop a variety of hyper-proliferative skin conditions, whose pathogenic basis is the paradoxical activation of the mitogen-activated protein kinase (MAPK) pathway in BRAF wild-type cells. Most of these hyper-proliferative skin changes improve when a MEK inhibitor is co-administered, as a MEK inhibitor blocks paradoxical MAPK activation. We tested whether we could take advantage of the mechanistic understanding of the skin hyper-proliferative side effects of BRAF inhibitors to accelerate skin wound healing by inducing paradoxical MAPK activation. Here we show that the BRAF inhibitor vemurafenib accelerates human keratinocyte proliferation and migration by increasing ERK phosphorylation and cell cycle progression. Topical treatment with vemurafenib in two wound-healing models in mice accelerated cutaneous wound healing and improved the tensile strength of healing wounds through paradoxical MAPK activation; addition of a MEK inhibitor reversed the benefit of vemurafenib-accelerated wound healing. The same dosing regimen of topical BRAF inhibitor did not increase the incidence of cutaneous squamous cell carcinomas in mice even after the application of a carcinogen. Therefore, topical BRAF inhibitors may have clinical applications in accelerating the healing of skin wounds. Overall design: Full depth incisional wound mice tissues with/without Vemurafenib treatment were sent for RNAseq analysis on day 2, 6 and 14

Description
The root apex is an important section of the plant root, involved in environmental sensing and cellular development. Analyzing the gene profile of root apex in diverse environments is important and challenging, especially when the samples are limiting and precious, such as in spaceflight. The feasibility of using tiny root sections for transcriptome analysis was examined in this study.To understand the gene expression profiles of the root apex, Arabidopsis thaliana Col-0 roots were sectioned into Zone-I (0.5 mm, root cap and meristematic zone) and Zone-II (1.5 mm, transition, elongation and growth terminating zone). Gene expression was analyzed using microarray and RNA seq.Both the techniques, arrays and RNA-Seq identified 4180 common genes as differentially expressed (with > two-fold changes) between the zones. In addition, 771 unique genes and 19 novel TARs were identified by RNA-Seq as differentially expressed which were not detected in the arrays. Single root tip zones can be used for full transcriptome analysis; further, the root apex zones are functionally very distinct from each other. RNA-Seq provided novel information about the transcripts compared to the arrays. These data will help optimize transcriptome techniques for dealing with small, rare samples. Overall design: Arabidopsis thaliana var. Columbia (COL-0) seedlings were grown on sterile solid media plates containing 0.5 % phytagel. The plates were vertically placed in growth chambers with continuous light (80-100 µmol m -2) at a constant temperature of 19° C. Eight day old seedlings were harvested into RNA-later solution in a 50 mL centrifuge tubes and stored at -20 °C freezer. The root tips were dissected into zone-I: 0.5mm from the tip including the root cap and root division zones, and zone-II: 1.5mm sections including root elongation and root hair zone. Microarray and sequencing experiments were performed.

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
Genome-wide transcriptome analysis was carried out in root tissue of Arabidopsis seedlings treated with gold (Au) as Chloroauric acid (HAuCl4). This study demonstrated remarkable changes in root transcriptome within the 12 h exposure. Most of the genes differentially expressed were related to glutathione binding, methylations, secondary metabolism, sugar metabolism, ABA, ethylene, auxin related signalling, transport and signal-transduction pathways.
