Description
Ets1-/- mice have an increase in B cell differentiation to plasma cells and increased serum immunoglobulin levels. The genes in B cells that are transcriptionally regulated by Ets1 and help regulate B cell differentiation are largely unknown. Here, we identify Ets1-regulated target genes in B cells using ChIP-seq and RNA-seq analysis. We found that Ets1 targets genes associated with immune response, mature B cell differentiation and regulation of B cell activation. Overall design: Quiescent follicular B cells were sorted from the spleens of wild-type and Ets1-/- mice using the following markers B220+ CD23-high CD21-low CD80-negative IgA-negative IgE-negative IgG1-negative IgG2a-negative IgG2b-negative IgG3-negative. Total RNA was prepared from sorted cells and subjected to RNA-sequencing.

Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
microRNA-126 is a microRNA predominately expressed by endothelial cells and controls angiogenesis. Unexpectedly, we found that mice deficient in miR-126 have a major impairment in their innate response to pathogen-associated nucleic acids, as well as HIV, which results in more widespread cell infection. Further examination revealed that this was due to miR-126 control of plasmacytoid DC (pDC) homeostasis and function, and that miR-126 regulates expression of TLR7, TLR9, NFkB1 and other innate response genes, as well as VEGF-receptor 2 (VEGFR2). Deletion of VEGFR2 on DCs resulted in reduced interferon production, supporting a role for VEGFR2 in miR-126 regulation of pDCs. These studies identify the miR-126/VEGFR2 axis as an important regulator of the innate response that operates through multiscale control of pDCs.

Description
Next generation sequencing was used to identify Notch mutations in a large collection of diverse solid tumors. NOTCH1 and NOTCH2 rearrangements leading to constitutive receptor activation were confined to triple negative breast cancers (TNBC, 6 of 66 tumors). TNBC cell lines with NOTCH1 rearrangements associated with high levels of activated NOTCH1 (N1-ICD) were sensitive to the gamma-secretase inhibitor (GSI) MRK-003, both alone and in combination with pacitaxel, in vitro and in vivo, whereas cell lines with NOTCH2 rearrangements were resistant to GSI. Immunohistochemical staining of N1-ICD in TNBC xenografts correlated with responsiveness, and expression levels of the direct Notch target gene HES4 correlated with outcome in TNBC patients. Activating NOTCH1 point mutations were also identified in other solid tumors, including adenoid cystic carcinoma (ACC). Notably, ACC primary tumor xenografts with activating NOTCH1 mutations and high N1-ICD levels were sensitive to GSI, whereas N1-ICD low tumors without NOTCH1 mutations were resistant. Overall design: Gene expression profiling for Notch-sensitive cancer cell lines using RNA-seq, each sample with triplicates

- Bovine Gene 1.0 ST Array (bovgene10st)
Description
Reproductive success depends on a functional oviduct for gamete storage, maturation, fertilization, and early embryonic development. The ovarian-derived sex steroids estrogen and progesterone have been found to influence cell proliferation, differentiation and functionality of the oviduct. The objective of this study was to investigate steroidal regulation of oviductal epithelial cell function by using the Bovine Gene 1.0 ST array (Affymetrix Inc., CA) for transcriptional profiling. Our overall goals were to increase our understanding of known epithelial cell processes critical for fertility, and to identify novel genes and biochemical processes for future analysis. Transcripts were annotated using NetAffx annotation database for the Bovine gene 1.0 ST array and last updated in June 2014.

Description
In the present study, we sought to understand the impact of obesity/metabolic disease (high-fat induced) on spinal cord injury (SCI) by examining transcriptome. Adult, male Long Evans rats received either thoracic level contusion of the spinal cord or sham laminectomy and then were allowed to recover on normal rat chow for 4 weeks and further on HFD for an additional 8 weeks. Spinal cord tissues harvested from the rats were processed for Affymetrix microarray and further transcriptomic analysis.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
The C-terminus of CBF-SMMHC, the fusion protein produced by a chromosome 16 inversion in acute myeloid leukemia subtype M4Eo, contains domains for self-mulimerization and transcriptional repression, both of which have been proposed to be important for leukemogenesis by CBF-SMMHC. To test the role of the fusion protein's C-terminus in vivo, we generated knock-in mice expressing a C-terminally truncated CBF-SMMHC (CBF-SMMHCC95). Embryos with a single copy of CBF-SMMHCDC95 were viable and showed no defects in hematopoiesis, while embryos homozygous for the CBF-SMMHCC95 allele had hematopoietic defects and died in mid-gestation, similar to embryos with a single-copy of the full-length CBF-SMMHCC95.
Publication Title
The C-terminus of CBFβ-SMMHC is required to induce embryonic hematopoietic defects and leukemogenesis.

Description
Nr4a1 deficient rats (Nr4a1-/-) were developed using the fawn hooded hypertensive rat (FHH), which provided a genetic background susceptible to kidney injury. Both groups of animals were evaluated for blood pressure, proteinuria, renal function, and whole transcriptome gene pathway changes. Gene expression profiling was performed at week 8, 16, and 24 using kidney from FHH and Nr4a1-/- rats. To identify differentially expressed gene between FHH and Nr4a1-/- two statistical methods were utilized: (1) FWER (family-wise error rate) procedure, p<0.05 and fold-change 1.2 or greater; and/or (2) Benjamani and Hochberg FDR (false discovery rate) using p<0.05, and fold-change 1.2 or greater. Two-way ANOVA using a p<0.01 or lower was performed to identify strain X time interaction effects between groups. Gene networks and functional analysis were evaluated through the use of Ingenuity Pathways Analysis .
