Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
We developed a Tet-inducible system to express deltaNp63alpha isoform under the control of keratin 5 promoter. Transgenic mice, which were Bigenic (BG) developed a severe skin phenotype with abnormal keratinocyte differentiation and defects in hair follicle development and cycling. Skin samples from transgenic animals and wild type animals were analyzed for global transcriptome changes.

Description
Analysis of protein tyrosine phosphatase 1B (PTP1B) deficient mammary glands from nulliparous mice at estrous and pregnancy day 3, 7, 10 and 15. We used a genetically ablated PTP1B mouse model to gain a deeper knowledge of the role PTP1B plays in mammary gland development and to define the mechanism regulated by this phosphatase.

Description
The role of estrogen and testosterone in the regulation of gene expression in the proximal reproductive tract is not completely understood. To address this question, mice were treated with testosterone or estradiol and RNA from the efferent ducts and caput epididymis was processed and hybridized to Affymetrix MOE 430 2.0 microarrays. Analysis of array output identified probe sets in each tissue with altered levels in hormone treated versus control animals. Hormone treatment efficacy was confirmed by determination of serum hormone levels pre- and post-treatment and observed changes in transcript levels of previously reported hormone-responsive genes. Tissue-specific hormone sensitivity was observed with 2867 and 3197 probe sets changing significantly in the efferent ducts after estrogen and testosterone treatment, respectively. In the caput epididymis, 117 and 268 probe sets changed after estrogen and testosterone treatment, respectively, demonstrating a greater response to hormone in the efferent ducts than the caput epididymis. Transcripts sharing similar profiles in the intact and hormone-treated animals compared with castrated controls were also identified. Ontological analysis of probe sets revealed a significant number of hormone-regulated transcripts encode proteins associated with lipid metabolism, transcription and steroid metabolism in both tissues. Real-time RT-PCR was employed to confirm array data and investigate other potential hormone-responsive regulators of proximal reproductive tract function. The results of this work reveal previously unknown responses to estrogen in the caput epididymis and to testosterone in the efferent ducts as well as tissue specific hormone sensitivity in the proximal reproductive tract.

- Affymetrix Zebrafish Genome Array (zebrafish)
Description
A microarray study of sex- and gonad-biased gene expression was conducted to determine whether zebrafish demonstrate male-specific patterns consistent with those observed in other animals. We identified a large number of genes (5899) demonstrating statistical differences in transcript abundance between male and female Danio rerio. All sex-biases in gene expression were due to differences between testis and ovary, although differences between male and female body likely went undetected due to constraints imposed by study design and statistical criteria. Male-enriched genes were more abundant than female-enriched genes, and the magnitude of expression bias for male-enriched genes was greater than that for female-enriched genes. We also identified a large number of candidate reproductive genes based on elevated transcript abundance in testes and ovaries, relative to male body and female body, respectively. Gene expression patterns in adult zebrafish from this study are consistent with the male-biased patterns typical of most animal taxa studied to date. Recent zebrafish studies designed to address more specific questions have not reported the same findings, but major methodological and analytical differences across these studies could explain discrepancies.

Description
Endothelin signaling is required for neural crest migration and homeostatic regulation of blood pressure. Here we report that constitutive over-expression of Endothelin-2 (Edn2) in the mouse retina perturbs vascular development by inhibiting endothelial cell (EC) migration across the retinal surface and subsequent EC invasion into the retina. Developing endothelial cells exist in one of two states: tip cells at the growing front, and stalk cells in the vascular plexus behind the front. This division of endothelial cell states is one of the central organizing principle of angiogenesis. In the developing retina, Edn2 over-expression leads to over-production of endothelial tip cells by both morphologic and molecular criteria. Spatially localized over-expression of Edn2 produces a correspondingly localized endothelial response. Edn2 over-expression in the early embryo inhibits vascular development at mid-gestation, but Edn2 over-expression in developing skin and brain has no discernable effect on vascular structure. Inhibition of retinal angiogenesis by Edn2 requires expression of Endothelin receptor A (Ednra) but not Ednrb in the neural retina. Taken together, these observations imply that the neural retina responds to Edn2 by synthesizing one or more factors that promote the endothelial tip cell state and inhibit angiogenesis. The response to Edn2 is sufficiently potent that it over-rides the activities of other homeostatic regulators of angiogenesis, such as vascular endothelial growth factor.

Description
Autophagy is a homeostatic cellular process involved in the degradation of long-lived/damaged cellular components. The role of autophagy in adipogenesis is well recognized, but its role in mature adipocyte function is largely unknown. We show that the autophagy proteins Atg3 and Atg16L1 are required for proper mitochondrial function in mature adipocytes. In contrast to previous studies, we found that post-developmental ablation of autophagy causes peripheral insulin resistance independently of diet or adiposity. Finally, lack of adipocyte autophagy reveals a - cross talk between fat and liver mediated by lipid peroxide-induced Nrf2 signaling. Our data reveal a - role for autophagy in preventing lipid peroxide formation and their transfer in insulin-sensitive peripheral tissues Overall design: Epididymal adipose tissue from 4 WT and 4 Adiponectin-Cre Atg3f/f male mice fed chow diet
