Affymetrix Mouse Expression 430A Array (moe430a)
Description
The integration of positive and negative intra- and extra-cellular signals dictates whether a cell will proliferate or differentiate. While it is intuitive to speculate that nutrients availability may influence this alternative, a comprehensive complement of the molecular determinants involved in this process has not been elucidated yet. In this study, we will investigate how nutrients (glucose) affect skeletal myogenesis. C2C12 cells will be cultured in high glucose and low glucose conditions, and their differenciation will be studied.

Description
To determine the effect of iBET762+, a bromodomain BET inhibitor, on the transcription of 20861 and 20863 cells. These cells are subclones of W12 cells, derived from cervical intraepithelial neoplastic lesion. 20861 contains integrated HPV16 DNA and 20863 contains extrachromosomal HPV16 DNA. iBET762+ decreases expression of the HPV16 E6 and E7 oncogenes in both cell lines and this is expected to have dramatic effects on the cellular transcriptome

Description
Cellular senescence is a stable proliferation arrest associated with an altered secretory pathway, the Senescence-Associated Secretory Phenotype (SASP). However, cellular senescence is initiated by diverse molecular triggers, such as activated oncogenes and shortened telomeres, and is associated with varied and complex physiological endpoints, such as tumor suppression and tissue aging. The extent to which distinct triggers activate divergent modes of senescence that might be associated with different physiological endpoints is largely unknown. To begin to address this, we performed gene expression profiling to compare the senescence programs associated with two different modes of senescence, oncogene-induced senescence (OIS) and replicative senescence (RS [in part caused by shortened telomeres]). While both OIS and RS are associated with many common changes in gene expression compared to control proliferating cells, they also exhibit substantial differences. These results are discussed in light of potential physiological consequences, tumor suppression and aging.

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
The objective of this study was to determine changes in gene expression within the extended amygdala following binge-like drinking by alcohol-preferring (P) rats. Adult male P rats were given 1-hr access to 15 and 30% ethanol (EtOH) three times daily for 8 weeks. Rats (n = 10/time point for EtOH and n = 6/time point for water) were killed by decapitation 1, 6 and 24 hr after the last drinking episode. Brains were extracted and rapidly frozen in isopentane in dry ice. RNA was prepared from individual micropunch samples of the nucleus accumbens shell (ACB-sh) and central nucleus of the amygada (CeA); microarray analyses were conducted with Affymetrix Rat 230.2 chips. EtOH intakes were 1.5-2 g/kg/session. Because too few genes changed at the individual time points, an overall effect, comparing the water and EtOH groups, was determined. In the ACB-sh and CeA, there were 276 and 402 probe sets for named genes, respectively, that were different between the two groups. There were 1.5- to 3.5- fold more genes up-regulated than down-regulated in both regions, with most differences between 1.1- to 1.2-fold. Although there were several significant Biological Processes categories in common between the 2 regions (e.g., synaptic transmission, neurite development), there were few genes in common between the two regions that differed between the EtOH and water groups. Overall, the results suggest that chronic binge-like alcohol drinking by P rats produces changes in the expression of genes that could alter neuronal function by different mechanisms in the ACB-sh and CeA.

Description
Four mature, non-lactating dairy cattle were transitioned from a high forage diet (HF; 0% grain) to a high grain diet (HG; 65% grain) that was fed for three weeks. Rumen papillae biopsies were performed during the HF baseline (week 0) and after the first (week 1) and third week (week 3) of the grain challenge to create a transcript profile for the the short and long-term adaption of the rumen epithelium during ruminal acidosis.
