Seed germination is a critical developmental process in plant propagation. Knowledge of the gene expression patterns in this critical process is important in order to understand the main biochemical reactions involved in successful germination, specially for economically relevant plants such as Maize.

View SamplesObesity is a chronic, complex and multifactorial disease that has reached pandemia levels and is becoming a serious health problem. Intestinal microbiota is considered a main factor that affects body weight and fat mass, which points toward a critical role in the development of obesity. In this sense, probiotic bacteria might modulate the intestinal microbiota and the mucosal-associated lymphoid tissue. The aim of this study was to investigate the effects of L. paracasei, L. rhamnosus and B. breve feeding on the intestinal mucosa gene expression in a genetic animal model of obesity.
Adamdec1, Ednrb and Ptgs1/Cox1, inflammation genes upregulated in the intestinal mucosa of obese rats, are downregulated by three probiotic strains.

View SamplesHeart failure (HF) is a major health and economic burden in developed countries. It has been proposed that the pathogenesis of HF may involve the action of mitochondria. Here we evaluate three different models of HF: tachycardiomyopathy, HF with preserved left ventricular (LV) ejection fraction, and LV myocardial ischemia and hypertrophy. Regardless of whether LVEF is preserved or reduced, our results indicate that the three models share common molecular features: an increase in mitochondrial ROS, followed by ultrastructural alterations in the mitochondrial cristae and loss of mitochondrial integrity that lead to cardiomyocyte death. We show that the ablation of the mitochondrial protease OMA1 averts cardiomyocyte death in all three experimental HF models, and thus, plays a direct role in cardiomyocyte protection. This finding identifies OMA1 as a potential target for preventing the progression of myocardial damage in HF associated to a variety of etiologies. Overall design: Transcriptome analysis of 12-week-old wild type mice versus OMA1 KO mice under control (non-treated) or treated with Isoproterenol chronically (implanted minipumps) for 7 days in heart tissue. The nuclear genetic background for both genotypes is C57BL/6JOlaHsd.

View SamplesCardiomyopathies-associated metabolic pathologies (e.g. T2D and insulin resistance) are a leading cause of mortality. It is known that the association between the pathologies works in both directions, where heart failure can lead to metabolic derangements such as insulin resistance. This intricate crosstalk exemplifies the importance of a fine coordination between one of the most energy demanding organs and an equilibrated carbohydrate metabolism. In this light, to assist in the understanding of the role of insulin regulated glucose transporters and the development of cardiomyopathies, we set out to study GLUT12. GLUT12 is a novel insulin regulated GLUT expressed in the main insulin sensitive tissues such as cardiac and skeletal muscle and adipose tissue. This study investigates the role of GLUT12 in heart failure and diabetes by developing a model for glut12 deficiency in zebrafish. Overall design: 6 samples in total were analyzed. 3 replicates from control samples (injected with contol MO) and 3 replicates from glut12 morphant samples (injected with glut12 splice MO). In each sample 10 embryos were pooled.

View SamplesTwo major subsets of rat natural killer (NK) cells can be distinguished based on their expression of either the Ly49s3 or the NKR-P1B lectin-like receptor. Ly49s3+ NK cells, but not NKR-P1B+ NK cells, express a wide range of Ly49 receptors.
Two complementary rat NK cell subsets, Ly49s3+ and NKR-P1B+, differ in phenotypic characteristics and responsiveness to cytokines.

View SamplesWe report the role of LSM1-7 complex in the Arabidopsis tolerance to abiotic stresses. LSM1-7 controls gene expression reprogramming at the post-transcriptional level by promoting the decapping of mRNA. This function is selectively achieve over selected stress-induced transcripts depending on stress nature. Overall design: Comparison of transcriptomes from Col-0 and lsm1a lsm1b plants exposed to low temperatures, drought or high salt conditions
