View SamplesPlants have evolved shoot elongation mechanisms to escape from diverse environmental stresses such as flooding and vegetative shade. The apparent similarity in growth responses suggests possible convergence of the signalling pathways. Shoot elongation is mediated by passive ethylene accumulating in flooded plant organs and by changes in light quality and quantity under vegetation shade. Here we study hypocotyl elongation as a proxy for shoot elongation and delineated Arabidopsis hypocotyl length kinetics in response to ethylene and shade. Based on these kinetics, we further investigated ethylene and shade-induced genome-wide gene expression changes in hypocotyls and cotyledons separately. Both treatments induced a more extensive transcriptome reconfiguration in the hypocotyls compared to the cotyledons. Bioinformatics analyses suggested contrasting regulation of growth promotion- and photosynthesis-related genes. These analyses also suggested an induction of auxin, brassinosteroid and gibberellin signatures and the involvement of several candidate regulators in the elongating hypocotyls. Pharmacological and mutant analyses confirmed the functional involvement of several of these candidate genes and physiological control points in regulating stress-escape responses to different environmental stimuli. We discuss how these signaling networks might be integrated and conclude that plants, when facing different stresses, utilise a conserved set of transcriptionally regulated genes to modulate and fine tune growth.

View SamplesEsophageal cancer is one of the deadliest cancers as patients present at late stages of disease. Frequent gene alterations include the loss of E-cadherin and TGFb receptor type II. The goal of this study was to establish a model of esophageal cancer by introducing dominant-negative mutants of E-cadherin and TGFb receptor II.

View SamplesStudies of adult human hematopoiesis have until now relied on the expression of CD10 to define lymphoid commitment. We report a novel lymphoid-primed population in human bone marrow that is generated from hematopoietic stem cells (HSC) prior to the onset of CD10 expression and B cell commitment, and is identified by high levels of the homing molecule L-selectin (CD62L). CD10-CD62Lhi progenitors have full lymphoid (B/T/NK) potential, and show reduced myeloid and absent erythroid potential. Genome-wide gene expression analysis demonstrates that the CD10-CD62Lhi population represents an intermediate stage of differentiation between CD34+CD38- HSC and CD34+lin-CD10+ progenitors marked by down-regulation of TAL1 and MPL, upregulation of E2A, CD3E and IL2RG expression, and absent B cell commitment or RAG1/2 expression. Immature CD34+CD1a- thymocytes are also CD62Lhi and L-selectin ligands are expressed at the cortico-medullary junction, suggesting a possible role for L-selectin in human thymic homing. These studies identify the earliest stage of lymphoid priming in human bone marrow.
Lymphoid priming in human bone marrow begins before expression of CD10 with upregulation of L-selectin.

View SamplesThis study profiles transcriptomic changes of Arabidopsis thaliana Col-0 in response to submergence. This dataset includes CEL files, RMA signal values and MAS5 P/M/A calls from total mRNA populations of plants at 9 to 10 leaf rosette stage. Biological replicates of root and shoot tissues were harvested after 7 h and 24 h of submergence in darkness along with corresponding non-submerged dark controls. To characterize the dark response, non-submerged light controls plants were harvested at the 0 h time point. Quantitative profiling of cellular mRNAs was accomplished with the Affymetrix ATH1 platform. Changes in the transcriptome in response to submergence and early darkness were evaluated, and the data led to identification of genes co-regulated at the conditional and organ-specific level.

View SamplesPurpose: The goals of this study were to identify quantitative gene expression differences between whole tumor and tumor-associated macrophages (TAMs) derived from Lewis lung carcinoma (LLC) tumors grown in wild type and PI3Kinase-gamma-null mice. Methods: mRNA profiles of whole tumor or tumor-associated macrophages (CD11b+Gr1- cells) from wild type (WT) or PI3Kinase-gamma-knockout (p110g-/-) mice were generated by single deep read sequencing, in triplicate or quadruplicate, using Illumina HiSeq 2000. The sequence reads that passed quality filters were aligned to mouse transcriptome using the bowtie2 aligner. Gene-level summaries were normalized and analyzed for differential expression using DESeq. Overall design: mRNA profiles of whole tumor and tumor-associated macrophages from WT and p110g-/- mice were generated by deep sequencing in triplicate or quadruplicate using Illumina HiSeq 2000.
