Affymetrix Human Genome U133A Array (hgu133a)
Description
Transforming growth factor beta 1 (TGF-1) is the most extensively studied growth factor in dentin-pulp complex, with pleiotropic effects on pulp response and healing. Our main objective was to analyze the expression profile of pulp tissue and odontoblasts, and the effects of TGF-1 on these profiles in cultured human pulp and odontoblasts with a specific interest in the anti- and pro-inflammatory cytokines.

Description
Knowledge of differential gene expression between pulp and odontoblasts might give insight to the regulation of these spatially related but functionally diverse cells. Our aim was large-scale analysis of expression profiles of native human pulp tissue and odontoblasts, and search for genes expressed only in odontoblasts.

Description
The prevalence of obesity has been increasing rapidly worldwide during the past two decades. This is alarming, since obesity has considerable effects on morbidity and mortality. The majority of gene expression studies about the effect of obesity and weight loss have been performed using the adipose tissue for mRNA extraction. However, also the liver plays a central role in maintaining energy balance. To our knowledge, no overall analysis of hepatic gene expression in response to changes in nutritional status has been made in humans Therefore, it is important to investigate how a short-time hypocaloric diet affects overall hepatic gene expression and the metabolic profile in a group of overweight and obese women. The subjects (n=31) were middle-aged, overweight (BMI>25 kg/m2) women with gallstone disease scheduled for an elective gallbladder operation. The intervention subjects were placed on a hypocaloric AHA step I diet with a recommended daily energy intake of 5.0 MJ. The objective was to reduce 0.5 kg of body weight per week. The control subjects were instructed to continue their habitual diet and not to lose weight. Basic clinical measurements and laboratory analyses were performed twice at baseline and at two week intervals during the weight reduction period. Surgical liver biopsies were obtained at the end of the weight reduction period. RNA samples of 4 individuals from the intervention group and 4 individuals from the control group were selected for the microarray analysis. The results from the microarray analysis were fairly surprising. Only one gene was up-regulated and the rest 142 down-regulated in the diet intervention group compared to the control group when a minimum of 2-fold change was set as the limit. The global decrease in hepatic gene expression was unexpected but the results are interesting, with several genes not previously linked to weight reduction. The decrease in triglyceride and fasting plasma insulin concentrations observed in our study is in accordance with results from many previous weight-loss trials.

Description
Objective: Dyslipidemia is one of the key factors behind coronary heart disease. Blood and lymphatic vessels play pivotal roles in both lipoprotein metabolism and development of atherosclerotic plaques. Recent studies have linked members of Vascular Endothelial Growth Factor (VEGF) family to lipid metabolism but the function of VEGF-D has remained unexplored. Here we investigated how the deletion of VEGF-D affects lipid and lipoprotein metabolism in atherogenic LDLR-/-ApoB100/100 mice. Approach and Results: Deletion of VEGF-D (Vegfd-/-LDLR-/-ApoB100/100) led to markedly elevated plasma cholesterol and triglyceride levels without an increase in atherogenesis. Size distribution and hepatic lipid uptake studies confirmed a delayed clearance of large chylomicron remnant particles that cannot easily penetrate through the vascular endothelium. Mechanistically, the inhibition of VEGF-D signaling significantly decreased the hepatic expression of syndecan 1 (SDC1), which is one of the main receptors for chylomicron remnant uptake when LDLR is absent. Immunohistochemical staining confirmed reduced expression of SDC1 in the sinusoidal surface of hepatocytes in VEGF-D deficient mice. Furthermore, hepatic RNA sequencing revealed that VEGF-D is also an important regulator of genes related to lipid metabolism and inflammation. The lack of VEGF-D signaling via VEGF receptor 3 led to lowered expression of genes regulating triglyceride and cholesterol production as well as downregulation of peroxisomal ß-oxidation pathway. Conclusions: These results demonstrate that VEGF-D, a powerful lymphangiogenic and angiogenic growth factor, is also a major regulator of chylomicron metabolism in mice. Overall design: Gene expression profiling of mouse liver tissue from control and VEGF-D knock-out mice. Control and VEGF-D KO mice were both in C57Bl/6 and atherosclerotic background, i.e., deficient of LDLR and expressing only apolipoprotein B100.

Expression profiling of sheep born to Australian industry sires with high and low genetic merit (Estimated Breeding Values or EBVs) for eye muscle depth (EMD). Progeny (40) from six Poll Dorset sires representing well defined extremes of EBVs for Eye Muscle Depth (low EBV EMD and high EBV EMD) were selected for analysis. The six sires were Australian industry sires with three sires representative of low EBV EMD and three representing high EBV EMD.
