To search for rapid changes in gene expression following BCR activation, we performed DNA microarray analysis of activated splenic B cells with and without anti-IgM treatment for 3 hour. The expression of a remarkably large set of genes differed significantly.

View SamplesA major part of plant immune response is mediated by signaling pathways controlled by three hormnes, jasmonate, ethylene, and salicylate. The involvement of each of these hormone signaling pathways in Arabidopsis thaliana was investigated in response to infection of a necrotrophic fungal pathogen, A. brassicicola. Arabideopsis mutants deficient in these hormone signaling pathways were compared to wild type.

View SamplesThe primary objective of the study was to investigate the uncoupling protein-1 (UCP1) associated features of human epicardial adipose tissue (eAT) using next generation deep sequencing. In addition, paired mediastinal adipose tissue (mAT) and subcutaneous adipose tissue (sAT) samples colleced from patients undergoing cardic surgeries at our center were included in the study. Overall design: Paired biopsies of eAT, mAT and sAT obtained from cardiac surgery patients (n=10), with specific criteria of high- and low- expression of UCP1 in eAT, were subjected to RNA sequencing. While the primary objective was to compare high- vs. low UCP1 expression in eAT, our study design further allowed us to investigate depot- and disease specific transcriptomic shifts in these patients. Specifically, 10 patients provided 30 samples (n = 10 each for eAT, mAT and sAT) that could be compared based on depot specificity (n = 10), obesity (n = 5 lean, n = 5 obese) and coronary artery disease (CAD) (n = 6 CAD, 4 = Non-CAD).

View SamplesEpstein-Barr virus (EBV) has evolved exquisite controls over its host cells, human B lymphocytes, not only directing these cells during latency to proliferate and thereby expand the pool of infected cells, but also to survive and thereby persist for the lifetime of the infected individual. Although these activities ensure the virus is successful, they also make the virus oncogenic, particularly when infected people are immunosuppressed. Here we show, strikingly, that one set of EBV’s miRNAs both sustain BL (Burkitt’s lymphoma) cells in the absence of other viral oncogenes and promote the transformation of primary B lymphocytes. Burkitt’s Lymphoma cells were engineered to lose EBV and found to die by apoptosis and could be rescued by constitutively expressing viral miRNAs in them. Two of these EBV miRNAs were found to target Caspase 3 to inhibit apoptosis at physiological concentrations.

View SamplesOsteoblasts are key players in bone remodeling. The accessibility of human primary osteoblast-like cells (HOb) from bone explants render them a lucrative model for studying molecular physiology of bone turnover, discovery of novel anabolic therapeutics and mesenchymal cell biology in general. Relatively little is known about resting and dynamic expression profiles of HObs and no studies have been conducted to date to systematically assess the osteoblast transcriptome. The aim of this study was to characterize HObs and investigate signaling cascades and gene networks using genomewide expression profiling in resting and Bone Morphogenic Protein (BMP)-2 and Dexamethasone induced cells.
