Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
TBR-760 (formerly BIM-23A760) is a chimeric dopamine (DA)-somatostatin (SST) compound with potent agonist activity at both DA type 2 (D2R) and SST type 2 (SSTR2) receptors. Non-functioning pituitary adenomas (NFPAs) express both D2R and SSTR2 and, consequently, may respond to TBR-760. We utilized a mouse model with the pro-opiomelanocortin (POMC) gene knocked-out that spontaneously develops aggressive NFPAs. Both genomic microarray and DA and SST receptor mRNA expression analysis indicate that POMC KO mouse tumors and human NFPAs have similar expression profiles, establishing POMC KO mice as a valid model for study of NFPAs. Treatment with TBR-760 for 8 weeks resulted in nearly complete inhibition of established tumor growth, whereas tumors from vehicle-treated mice increased in size by 890 ± 0.7%. These results support the development of TBR-760 as a therapy for patients with NFPA.

Description
In the vertebrate retina, the Otx2 transcription factor plays a crucial role in the cell fate determination of both rod and cone photoreceptors. Otx2 conditional knockout (CKO) mice exhibited a total absence of rods and cones in the retina due to their cell fate conversion to amacrine-like cells. In order to investigate the entire transcriptome regulated by Otx2 in the developing retina, we performed microarray analysis on the Otx2 CKO retina.

- Affymetrix Human Transcriptome Array 2.0 (hta20)
Description
Embryonic stem cells are pluripotent and possess the ability to differentiate into numerous lineages during the developmental process. In similarity to embryonic stem cells, human induced pluripotent stem cells (iPSCs) possess the potential to differentiate into multiple lineages making them an excellent research tool. We generated iPSCs from multiple donors and also differentiated iPSCs from these donors into human neural stem/progenitor cells (NSCs). We used human transcriptome arrays to detail the programme of gene expression underlying NPC induction and identified distinct classes of up-regulated genes during this process.

Description
Mouse bone marrow-derived macrophages (BMDM) grown in macrophage colony-stimulating factor (CSF-1) have been used widely in studies of macrophage biology and the response to toll-like receptor agonists. We investigated whether similar cells could be derived from the domestic pig. Cultivation of pig bone marrow cells for 5-7 days in presence of rhCSF-1 generated a pure population of BMDM that expressed the usual macrophage markers (CD14, CD16, CD163, CD172a), are potent phagocytic cells and produced tumor necrosis factor (TNF) in response to lipopolysaccharide (LPS). Bone marrow cells could be stored frozen and thawed, providing a renewable resource.

Description
Systemic administration of -adrenoceptor (-AR) agonists has been found to induce skeletal muscle hypertrophy and significant metabolic changes. In the context of energy homeostasis, the importance of -AR signaling has been highlighted by the inability of 13-AR-deficient mice to regulate energy expenditure and susceptibility to diet induced obesity. However, the molecular pathways and gene expression changes that initiate and maintain these phenotypic modulations are poorly understood. Therefore, the aim of this study was to identify differential changes in gene expression in murine skeletal muscle associated with systemic acute administration of the 2-AR agonist formoterol. Skeletal muscle gene expression (from murine tibialis anterior) was profiled at both 1 and 4 hours following systemic administration of the 2-AR agonist formoterol, using 46K Illumina(R) Sentrix BeadArrays. Illumina expression profiling revealed significant expression changes in genes associated with skeletal muscle hypertrophy, myoblast differentiation, metabolism, circadian rhythm, transcription, histones, and oxidative stress.

Description
Protein arginine methyltransferase-6 (PRMT6) regulates steroid-dependent transcription and alternative splicing, and is implicated in endocrine system development and function, cell death, cell cycle, gene expression and cancer. Despite its role in these processes, little is known about its function and cellular targets in breast cancer. To identify novel gene targets regulated by PRMT6 in breast cancer cells, we used a combination of small interfering RNA (siRNA) and exon-specific microarray profiling in vitro, coupled to in vivo validation in normal breast and primary human breast tumours. This approach, which allows the examination of genome-wide changes in individual exon usage and total transcript levels, demonstrated PRMT6 knockdown significantly affected: (i) the transcription of 159 genes, and (ii) alternate splicing of 449 genes. Importantly, the levels of PRMT6 itself were significantly decreased in breast cancer, relative to normal breast tissue. The PRMT6 dependent transcriptional and alternative splicing targets identified in vitro, were validated in human breast tumours. Notably, expression of PRMT6 and the corresponding gene signature, correlated with decreased probability of relapse-free or distant metastasis free survival in ER+ breast cancer. These results suggest that dysregulation of PRMT6 dependent transcription and alternative splicing may be involved in breast cancer pathophysiology and the molecular consequences identifying a unique and informative biomarker profile.
