Expression data from TH17 cells cultured in the presence or absence of glutamine

Project description:T cell fate and function is closely related to nutrient uptake and utilization. Here we demonstrate that glutamine deprivation switch Th17 cells to Treg cells in a time and dose dependent manner. The finding highlight the critical role of glutamine in T cell fate determination through a metabolic-epigenetic axis. We performed microarrays to explore the gene expression pattern of TH17 cells in the presence or absence of glutamine.

Gene expression analysis of H1299 cells in response to the presence or absence of glutamine or glucose

Project description:By a transcriptome analysis using RNA sequencing in H1299 cells, a non-small cell lung cancer cell line (NSCLC), we determined the response of lipogenic genes to absence vs. presence of glutamine (Gln) or glucose (Gluc). We found that neither glutamine nor glucose alone was able to activate the expression of genes regulating fatty acid and cholesterol synthesis, and uptake, including SREBF1, SREBF2, ACLY, ACACA, FASN, SCD1, HMGCR and LDLR, as compared to absence of both. And, activation of lipogenic genes required the presence of both glutamine and glucose, but SCAP gene expression was not affected by either glutamine or glucose. The RNA sequencing analysis in H1299 cells also confirmed that ammonia, similarly to glutamine, significantly activated the expression of genes controlling the fatty acid and cholesterol synthesis pathways as compared to glucose alone. This study detemines the intrinsic molecular connection between glutamine, glucose and lipid synthesis.

Analysis of Th17 gene signature in the presence of CD28 costimulation in human CD4 naïve T cells

Project description:We determined differentially regulated gene expression profile in CD4 naïve T cells cultured in presence or absence of Th17 inducing cytokines (IL23+IL1β) and anti-CD28. We reported that CD28 costimulation induced Th17-suppressive gene signature.

Directed differentiation to nephron progenitor cells in the presence and absence of glutamine [RNA Seq 2]

Project description:Metabolic pathways driving differentiation into nephron progenitor cells (NPCs) and renal organoids from the pluripotency stage remain poorly understood. In this study, we systematically performed comprehensive metabolite and transcriptome profiling of human pluripotent stem cells (hPSCs) during differentiation into NPCs and further into multicellular organoids. We found activation of distinct metabolic pathways during early-stage progression from hPSCs to NPCs; however, later-stage differentiation from NPCs to organoids, and the intervening developmental stages between them, largely shared similar metabolic profiles. Among the pathways changing in early differentiation, the alanine-aspartate-glutamate and glutamine pathways were found to be significantly altered by both an enrichment and by pathway impact analysis. Moreover, hPSCs survived glutamine deprivation during in vitro differentiation, and NPCs were successfully generated both in the absence and presence of glutamine and glutamate. Surprisingly, glutamine deprivation resulted in enhanced maturation, by accelerating PAX8 expression, and enriching for podocytes as detected through single cell RNA-Seq analysis. Taken together, these findings highlight a critical regulatory role of glutamine metabolism in the derivation of nephron progenitor cells and renal organoids and identify a controlling metabolic pathway of early renal differentiation.

Effects of TNF-alpha blocking in sorted Th17 cells from co-cultures of human CD4-positive and CD14-positive cells

Project description:Human CD4+ T cells and CD14+ monocytes from healthy donors were co-cultured with anti-CD3 for three days in the presence or absence of TNF-alpha mAb (Adalimumab). Classical Th17 cells (Th17) or those generated in the presence of the inhibitor (iTh17) were then sorted and analyzed by full transcriptome microarray analysis.

Gene expression analysis of human CD4+ T cells differentiated into Th17 cells in the presence of high-salt

Project description:Th17 cells are believed to be a critical cell population for driving autoimmune diseases. However, environmental factors that are directly related to the development of Th17 cells are largely unknown. High-salt (NaCl) concentrations enhance Th17 differentiation of human naive CD4+ T cells in vitro. The aim of the study was to analyse the changes in gene expression induced by high-salt conditions during Th17 differentiation. Naive human CD4+ T cells were in vitro differentiated into Th17 cells in the presence or absence of high-salt. We arrayed 2 different donors for each condition (control & high-salt).

Differentiating i-Mixl1 mESCs cultured in the presence or absence of Doxycycline

Project description:We profiled gene expression changes in differentiating i-Mixl1 ES cells(Willey, Ayuso-Sacido et al., 2006, Blood 107(8): 3122-3130) cultured in the presence or absence of Doxycycline (DOX, 0.1 ug/ml, 3 replicates per treatment/time point). Total RNA was isolated from EBs harvested at day 2, 3 and 4 (DOX added 1 day after plating of ES cells). RNA (1 ug) was subjected to one round of linear amplification (RiboAmp System) to yield 10 ug of RNA. The RNA was indirectly labeled using amino allyl-dUTP('t Hoen, de Kort et al., 2003, Nucleic Acids Res. 31: e20), then conjugated with Cy3 or Cy5. The labeled RNAs were used to screen a 15K mouse developmental cDNA microarray(Tanaka, Jaradat et al., 2000, Proc. Natl. Acad. Sci. U.S.A. 97: 9127-9132). Pairwise analysis of hybridization results for EBs cultured with or without DOX was performed for samples harvested on each day. Spotfire(R) software was used for data management and filtering. Gene expression ratios were normalized after filtering the data to remove low-intensity and poor quality spots. Data obtained for replicate samples were in excellent agreement. Six experiments total: three time points (day 2, day 3, day 4); for each time point mRNA was collected in the presence or absence of Doxycycline. Three biological replicas were collected for each of the six experiments
