We have found that the cell yield of oligodendrocyte precursor cells (OPCs) are higher in 31.5 than in 37 not by suppression of apoptosis but by enhancement of proliferation.

View SamplesIt has been reported that repeated intra-tracheal instillation of S. chartarum spores induced significant pulmonary arterial remodeling in mice, which resulted in pathological changes like human pulmonary arterial hypertension (PAH) and elevation right ventricle systolic pressure.

View SamplesRetinoid X receptor (RXR)-gamma is a nuclear receptor-type transcription factor expressed mostly in the skeletal muscle, and regulated by nutritional conditions. Previously, we established transgenic mice overexpressing RXR-gamma in the skeletal muscle (RXR-gamma mice), which showed lower blood glucose than the control mice. We used microarrays to investigate their glucose metabolism gene expression change.

View Samplessmall RNA libraries from wild-type and Hen1 mutant testes were made with either polyA tailing (VASAGFPHen1minus/plus) or adapter ligation (Hen1Testis and WTTestis) and sequenced on an Illumina GAII platform. Overall design: RNA was isolated from total testis tissue of both Hen1 wildtype and Hen1 mutant animals. After size selection from gel, the small RNA libraries wre made.

View SamplesChronic opiate use produces molecular and cellular adaptations in the nervous system, leading to tolerance, physical dependence and addiction. Genome-wide comparison of morphine-induced changes in brain transcription of mouse strains with different opioid-related phenotypes provides an opportunity to discover the relationship between gene expression and behavioral response to the drug.

View SamplesThere is massive destruction of transcripts during maturation of mouse oocytes. The objective of this project was to identify and characterize the transcripts that are degraded versus those that are stable during the transcriptionally silent germinal vesicle (GV)-stage to metaphase II (MII)-stage transition using the microarray approach. A system for oocyte transcript amplification using both internal and 3-poly(A) priming was utilized to minimize the impact of complex variations in transcript polyadenylation prevalent during this transition. Transcripts were identified and quantified using Affymetrix Mouse Genome 430 v2.0 GeneChip. The significantly changed and stable transcripts were analyzed using Ingenuity Pathways Analysis and GenMAPP/MAPPFinder to characterize the biological themes underlying global changes in oocyte transcripts during maturation. It was concluded that the destruction of transcripts during the GV to MII transition is a selective rather than promiscuous process in mouse oocytes. In general, transcripts involved in processes that are associated with meiotic arrest at the GV-stage and the progression of oocyte maturation, such as oxidative phosphorylation, energy production, and protein synthesis and metabolism, were dramatically degraded. In contrast, transcripts encoding participants in signaling pathways essential for maintaining the unique characteristics of the MII-arrested oocyte, such as those involved in protein kinase pathways, were the most prominent among those stables.

View SamplesWe previously found that mice with heterozygous knockout of the alpha-isoform of calcium/calmodulin-dependent protein kinase II (alpha-CaMKII HKO mice) show various dysregulated behaviors, including cyclic variations in locomotor activity (LA), suggesting that alpha-CaMKII HKO mice may serve as an animal model showing infradian oscillation of mood. We performed gene expression microarray analysis of dentate gyrus from alpha-CaMKII HKO mice. Mice were selected for the sampling such that their LA levels varied among the mice.
