(Submitter supplied) Delayed access to feed following hatching has been associated with reduction in growth performance in chicks. However, the gene networks within the hypothalamus that regulate feed intake and metabolism, and the effects of fasting on those pathways are not well understood. The present experiment evaluated global hypothalamic gene expression in neonatal chicks using the Arizona Gallus gallus 20.7K Oligo Array v1.0 to elucidate genes and pathways regulated by feeding, fasting, and refeeding. more...

(Submitter supplied) This study integrates global transcriptional profiling and the metabolic perturbation induced by fasting and re-feeding. Genetic control of growth and development should be revealed by systematic modeling of metabolic and regulatory pathways. Chicken oligo arrays were used for transcriptional profiling in two time-course experiments. Two critical developmental stages were chosen: immediately after hatchling (Wk1) and prior to marketing of broiler chickens (Wk6). more...

(Submitter supplied) d-serine is naturally present throughout the human body. It is also used as add-on therapy for treatment-refractory schizophrenia. d-Serine interacts with the strychnine-insensitive glycine binding site of NMDA receptor, and this interaction could lead to potentially toxic activity (i.e., excitotoxicity) in brain tissue. The transcriptomic changes that occur in the brain after d-serine exposure have not been fully explored. more...

Analysis of forebrains of animals treated with up to 500 mg/kg D-serine for 96 hours. D-serine is involved in many physiological processes through its interaction with the glycine binding site of the NMDA receptor. Results provide insight into the impact of D-serine exposure on neuronal functions.

(Submitter supplied) Four weeks old male broilers, fed ad libitum or fasted for 16h or 48h were used to describe the evolution of global gene expression profiles in chicken liver during a 48h fasting period using a chicken 20K oligo array. Among the 20460 oligos on the microarray, 13057 were identified as aligning with a unique coding region of the 2.1 Washington University assembly of the chicken sequence genome. So the statistical analyses were performed on this 13057 gene set. more...

(Submitter supplied) Several processes governing growth and metabolism are regulated by the neuroendocrine system, particularly the trophic hormones produced in the anterior pituitary gland. However, many of the differences that exist in pituitary gene expression and functional gene networks associated with divergent growth characteristics are still largely unknown. Using the Del-Mar 14K Chicken Integrated Systems microarray, this experiment evaluated global gene expression in the anterior pituitary gland during the first 7 weeks of post-hatch growth in two lines of chickens genetically selected for high growth (HG) or low growth (LG) at SRA-INRA, France. more...

(Submitter supplied) The sensation of hunger after a period of fasting and the sensation of satiety after eating is crucial to behavioral regulation of food intake, but the biological mechanisms regulating these sensations are incompletely understood. We studied the behavioral and physiological adaptation to fasting in the vinegar fly (Drosophila melanogaster). Here we show that flies demonstrated increased behavioral attraction to food odor when food-deprived with no corresponding increase in sensitivity in the peripheral olfactory system. more...

(Submitter supplied) Addictive drugs including opioids activate signal transduction pathways that regulate gene expression in the brain. However, changes in CNS gene expression following morphine exposure are poorly understood. We studied the effect of short- and long-term morphine treatment on gene expression in the hypothalamus and pituitary using genome-wide DNA microarray and real-time reverse transcriptase polymerase chain reaction (RT-PCR) analyses. more...

(Submitter supplied) This array was made using the PGA mouse 70mer oligo library generated at Massachusetts General Hospital. The 19,556 oligos were designed using the OligoPicker software generated at the facility and available for free download at http://pga.mgh.harvard.edu/oligopicker/. Oligos were selected using a stringent set of filters to ensure specific representation of all protein-coding sequences in the NCBI GenPept database. more...

(Submitter supplied) Hypothalami from Fat (FL) and Lean lines (LL) of juvenile broiler chickens were obtained by divergent selection for high or low levels of abdominal fat at SRA-INRA, France. Gene expression patterns were measured during the development of adiposity at 1 to 7 weeks of age. Differentially expressed genes associated with line, age, or line-by-age were identified. Various phenotypic and metabolic alterations are present between the lines (i.e., abdominal fat, T3 levels and glycemia), however there are no alterations in ad libitum food intake between the lines. more...

(Submitter supplied) Role of alternative polyadenylation (APA) in rat brain after vaporized cannabis plant matter (CPM) exposure remains largely undetermined. Our WTTS-seq approach to capture 3'-end of RNAs clearly revealed alternative polyadenylation events responsible for dominantly down-regulates APA expression on Glutamatergic Transcripts in rats after CPM Exposure.

(Submitter supplied) We applied Whole Transcriptome Termini Site Sequencing (WTTS-seq) to detect differences in use of alternative polyadenylation sites between diet-induced obesity rats and control rats. Our finding clear showed that a nutritionally complete high fat diet would affect pre-translational alternative polyadenylation events on hypothalamic transcripts that both stimulate and counter regulate body weight.
