Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Parathyroid hormone (PTH) plays an essential role in regulating calcium and bone homeostasis in the adult, but whether PTH is required at all for regulating fetal-placental mineral homeostasis is uncertain. To address this we treated Pth-null mice in utero with 1 nmol PTH (1-84) or saline and examined placental calcium transfer 90 minutes later. It was found that placental calcium transfer increased in Pth-null fetuses treated with PTH as compared to Pth-null fetuses treated with saline. Subsequently, to determine the effect of PTH treatment on placental gene expression, in a separate experiment, 90 minutes after the fetal injections the placentas were removed for subsequent RNA extraction and microarray analysis.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Most tumors are epithelial-derived, and although disruption of polarity and aberrant cellular junction formation is a poor prognosticator in human cancer, the role of polarity determinants in oncogenesis is poorly understood. Using in vivo selection, we identified a mammalian orthologue of the Drosophila polarity regulator crumbs as a gene whose loss of expression promotes tumor progression. Immortal baby mouse kidney epithelial (iBMK) cells selected in vivo to acquire tumorigenicity displayed dramatic repression of crumbs3 (crb3) expression associated with disruption of tight junction formation, apicobasal polarity, and contact-inhibited growth. Restoration of crb3 expression restored junctions, polarity and contact inhibition, while suppressing migration and metastasis. These findings suggest a role for mammalian polarity determinants in suppressing tumorigenesis that may be analogous to the well-studied polarity tumor suppressor mechanisms in Drosophila.

Illumina HiSeq 2500
Description
Purpose: To identify the impact of thermoneutral housing as opposed to standard housing on gene expression profiles in the mouse peripheral blood mononuclear cells (PBMCs), focusing on proinflammatory immune responses and high-fat diet induced non-alcoholic fatty liver disease pathogenesis. Methods: Expression profiles from PBMCs collected from C57Bl6 mice fed chow or high-fat diet for 8 weeks, following 2 weeks at either standard or thermoneutral housing conditions. Sequencing was performed in duplicate, the Illumina HiSeq 2500. Transcripts that passed quality filters were analyzed at the gene level, using Strand NGS for accurate alignment and quantification. Results: We mapped approximately 20million reads per sample to the mm10 genome using annotations produced by Ensembl, which represented 36186 transcripts. Approximately 14000 genes exhibited reasonable expression in at least one experimental condition. The primary focus was the effect of housing temperature while holding diet consistent (i.e. thermoneutral vs standard, both on high-rat diet), where ~2700 genes exhibited differential regulation. Conclusions: We present the transcriptomic profile of PBMCs from mice fed chow of high-fat diets, following either standard or thermoneutral housing. We obseve an augmented proinflammatory immune response. Overall design: PBMC expression profiles were characterized following eight weeks of chow or high-fat diet, following two weeks of standard or thermoneutral housing.

Description
Deficiency of the human short stature homeobox-containing gene (SHOX) has been identified in several disorders characterized by reduced height and skeletal anomalies such as Turner, Leri-Weill and Langer syndrome as well as idiopathic short stature. Although highly conserved in vertebrates, rodents lack a SHOX orthologue.

Description
Autophagy is a starvation response that facilitates cell survival under metabolic stress and yet defects in autophagy promote tumorigenesis. While the role of understarvation is relatively clearer, its mechanistic role in tumorigenesis is poorly understood. We show that defective autophagy promotes protein damage and accumulation of p62, a marker for protein damage accumulation that is cleared through autophagy pathway. The failure to eliminate p62 in autophagy-defective cells, leads to deregulation of cell signalling and gene expression and ultimately promotes tumorigenesis. Thus defective-autophagy is a mechanism for p62 accumulation commonly observed in human tumors.
Publication Title
Autophagy suppresses tumorigenesis through elimination of p62.
