Affymetrix Rice Genome Array (rice)
Description
Traditional rice varieties found in India have many desirable characteristics. Amongst them, their differential responses to abiotic and biotic stresses are of great agricultural importance. Drought or osmotic stress is one of the major abiotic stresses afflicting crop plants in India. Indigenous varieties like Dagad deshi have been found to be drought resistant and, thereby, are being studied in great detail by plant breeders and biotechnologists alike. In this study, we have analyzed the transciptomes of two contrasting cultivars, i.e. Dagad deshi (tolerant) and IR20 (susceptible), under control and stress conditions to elucidate the differences in their responses to drought stress using Affymetrix microarray platform.

Description
Acute myeloid leukemia (AML) is associated with poor clinical outcome and the development of more effective therapies is urgently needed. G protein-coupled receptors (GPCRs) represent attractive therapeutic targets, accounting for approximately 30% of all targets of marketed drugs. Using next-generation sequencing, we studied the expression of 772 GPCRs in 148 genetically diverse AML specimens, normal blood and bone marrow cell populations as well as cord blood-derived CD34-positive cells. Among these receptors, 30 are overexpressed and 19 are downregulated in AML samples compared with normal CD34-positive cells. Upregulated GPCRs are enriched in chemokine (CCR1, CXCR4, CCR2, CX3CR1, CCR7 and CCRL2), adhesion (CD97, EMR1, EMR2 and GPR114) and purine (including P2RY2 and P2RY13) receptor subfamilies. The downregulated receptors include adhesion GPCRs, such as LPHN1, GPR125, GPR56, CELSR3 and GPR126, protease-activated receptors (F2R and F2RL1) and the Frizzled family receptors SMO and FZD6. Interestingly, specific deregulation was observed in genetically distinct subgroups of AML, thereby identifying different potential therapeutic targets in these frequent AML subgroups. Overall design: Total healthy bone marrow was sorted to isolate distinct cell populations. RNA-Seq analysis was performed on sorted cells to determine gene expression profile of healthy bona marrow subpopulations.

Description
Intestinal macrophages rely on the constant replenishment by bone marrow derived Ly6Chigh monocytes in the adult organism. The developmental path from monocytes towards intestinal macrophages locally in the tissue is defined by the loss of Ly6C and acquisition of MHCII and CX3CR1 expression. We used microarray analysis to further characterise this local differentiation process.

We analysed the transcriptome of different HSC-enriched subpopulations of cells sorted from human umbilical cord blood and isolated from several individuals with different genetic backgrounds. We aim at identifying new cell surface markers associated with human HSC and downstream mature hematopoietic cell activity. Overall design: RNA-seq of CD34+CD45RA- cord blood cells from 17 non-pooled individuals.

Description
The goal of the study was to identify genes that are directly or indirectly coregulated by the AhR pathway in primary human AML cells. Patient AML cells were treated for 16 hours with the two indirubin derivatives 6-bromoindirubin-3''oxime (BIO), 1-Methyl-6-bromoindirubin-3''oxime (MeBIO), the AHR-antagonist SR1 (StemReginin1), combinations of BIO+SR1 and MeBIO+SR1 or DMSO alone at indicated concentrations prior to RNA extraction for sequencing. Overall design: RNA-Seq performed on 5 primary AML samples fresh (t0) and after exposure to AhR-agonists (2), -antagonist (1), and DMSO Contributor: Leucegene Project, IRIC

Description
Gut-draining mesenteric lymph nodes (mLNs) play a key role in peripheral tolerance towards food and commensal antigens by providing an optimal microenvironment for efficient de novo induction of Foxp3+ regulatory T cells (Tregs). We recently identified mLN stromal cells as critical cellular players in this process and demonstrated that their tolerogenic properties are imprinted by microbiota. Here, we show that this imprinting process already takes place in the neonatal phase and renders the mLN stromal cell compartment resistant to inflammatory perturbations later in life. Utilizing LN transplantation, RNA-seq and single-cell RNA-seq allowed identification of stably imprinted expression signatures in mLN fibroblastic stromal cells. We dissected common stromal cell subsets across gut-draining mLNs and skin-draining LNs with location-specific immunomodulatory functions, such as subset-specific expression of Aldh1a2/3. Accordingly, mLN stromal cells shaped resident dendritic cells to attain high Treg-inducing capacity in a Bmp2-dependent manner. Thus, crosstalk between mLN stromal and resident dendritic cells provides a robust feedback mechanism for the maintenance of intestinal tolerance. Overall design: Transcriptomic analysis of fibroblastic stromal cells of skin-draining and intestinal-draining lymph nodes from endogenous and transplanted lymph nodes at the popliteal fossa.
