Affymetrix Human Genome U133A 2.0 Array (hgu133a2)
Description
Background: Obesity is a risk factor for breast cancer in postmenopausal women and is associated with decreased survival and less favorable clinical characteristics such as greater tumor burden, higher grade, and poor prognosis, regardless of menopausal status. Despite the negative impact of obesity on clinical outcome, molecular mechanisms through which excess adiposity influences breast cancer etiology are not well-defined.

Illumina HiSeq 4000
Description
Purpose: identifying genes responding to insulin stimulation in S2R+ cells through whole transcriptome RNA-seq analyses Methods: Total RNA was extracted from S2R+ cells using TRIzol® reagent (Invitrogen). After assessing RNA quality with an Agilent Bioanalyzer, libraries were constructed with Illumina TruSeq mRNA Library Prep Kit , libraries were sequenced using an Illumina HiSeq 4000 at the Columbia Genome Center (http://systemsbiology.columbia.edu/genome-center). Results: Using an time series data analysis workflow incorporating polynormials , we identified 1254 temproally differentially expressed genes responding to insulin stimulation in the S2R+ cells. Overall design: the pre-starved S2R+ cells ( with serum free medium) were stimulated with insulin; triplicate samples were collected at basline and every 20minutes time interval up to three hours; transcriptome profiling

Description
Uremic media calcification is not only driven by systemic factors such as hyperphosphatemia, but also crticially dependent on vascular smooth muscle cells per se. We hypothesized that the different developmental origins of vscular smooth muscle cells might lead to a heterogeneous susceptibility to develop media calcification.

Description
Purpose: Aerobic capacity is a strong predictor of cardiovascular mortality. To determine the relationship between inborn aerobic capacity and soleus gene expression we examined genome-wide gene expression in soleus muscle of rats artificially selected for high and low running capacity (HCR and LCR, respectively) over 16 generations. The artificial selection of LCR caused accumulation of risk factors of cardiovascular disease similar to the metabolic syndrome seen in man, whereas HCR had markedly better cardiac function. We also studied alterations in gene expression in response to exercise training in the two groups, since accumulating evidence indicates that exercise has profound beneficial effects on the metabolic syndrome.

Description
Aerobic capacity is a strong predictor of cardiovascular mortality. To determine the relationship between aerobic capacity and cardiac gene expression we examined genome-wide gene expression in hearts of rats artificially selected for high- and low running capacity (HCR and LCR, respectively) over 16 generations. HCR were born with an athletic phenotype, whereas LCR exhibited features of the metabolic syndrome.

Description
Truncating CHD8 mutations are amongst the highest confidence risk factors for autism spectrum disorders (ASD) identified to date. Here, we report that Chd8 heterozygous mice display increased brain size, motor delay, hypertelorism, pronounced hypoactivity, and anomalous responses to social stimuli. Whereas gene expression in the neocortex is only mildly affected at mid gestation, over 600 genes are differentially expressed in the early postnatal neocortex. Genes involved in cell adhesion and axon guidance are particularly prominent amongst the downregulated transcripts. Resting-state functional MRI identified increased synchronized activity in corticohippocampal and auditory-parietal networks in Chd8 heterozygous mutant mice, implicating altered connectivity as a potential mechanism underlying the behavioral phenotypes. Together, these data suggest that altered brain growth and diminished expression of important neurodevelopmental genes that regulate long-range brain wiring are followed by distinctive anomalies in functional brain connectivity in Chd8 +/- mice. Human imaging studies have reported altered functional connectivity in ASD patients, with long-range under-connectivity seemingly more frequent. Our data suggest that CHD8 haploinsufficiency represents a specific subtype of ASD where neuropsychiatric symptoms are underpinned by long-range over-connectivity. Overall design: RNA was isolated from microdissected cortices at E12.5 (both hemispheres) and P5 (one hemisphere and DNase-treated using the Direct-zol RNA MiniPrep kit (Zymo Research) according to the manufacturer?s instructions (n = 3 per experimental group). cDNA was end-repaired, adaptor-ligated, and A-tailed. Samples were sequenced over 2 lanes of the Illumina HiSEq 4000 platform.
