Description
To understand how an inhibition of the mitochondrial ATP synthase affects transcriptional programming and to identify potential candidates of the signaling machinery involved in ATP synthase deficiency responses, we used oligomycin on seedling liquid cultures. Seedlings were harvested at time points 0, 1 and 4 h after the start of oligomycin and control (EtOH) treatments. Already 1 h after addition of oligomycin a total of 102 genes were more than threefold up-regulated and 14 genes were repressed, with most of them showing persistent changes. After 4 h, 580 additional genes were more than threefold up-regulated, and 152 genes were repressed by oligomycin. Several genes for alternative NAD(P)H dehydrogenases and alternative oxidases (AOX1a, AOX1d and NDA1) were up-regulated early, and additional homologs (NDA2, NDB2, NDB4 and AOX1b) followed 4 h after the start of treatment. Several genes for subunits of complex I, complex IV and the ATP synthase were induced whereas hardly any genes encoding enzymes of glycolysis and the TCA cycle changed. Additionally, four of five hallmark genes for oxidative stress were increased by oligomycin. These genes are At2g21640 (UPOX), At1g19020, At1g05340 and At1g57630 and code for proteins of unknown function. Among oxidative stress proteins with known functions, several H2O2-responsive Glutathione-S-transferases and BCS1 (CYTOCHROME BC1 SYNTHESIS) were strongly up-regulated already after 1 h. BCS1 is induced by salicylic acid and independent of other reactive oxygen signaling (ROS) pathways, such as H2O2. The results indicate that several different ROS and defense signaling pathways were induced simultaneously by oligomycin. This is further corroborated by induction of several transcription factors of the WRKY and NAC families, which have been previously implicated in coordinating cellular defense signaling.

Description
In our efforts to evaluate the function of the IL-8 receptor CXCR2 in Acute Lymphoblastic Leukemia (ALL) cells, we made use of SB225002 (N-(2-hydroxy-4-nitrophenyl)-N-(2-bromophenyl)urea), a drug initially described as a CXCR2 antagonist. Although the CXCR2 receptor was found to be non-functional in ALL, B- and T-ALL cell lines were sensitive to SB225002.

Description
Genome-wide association studies in human type 2 diabetes (T2D) have renewed interest in the pancreatic islet as a major site of T2D risk. In this study, microarray data collected from mouse islets were used to identify genes that are regulated by cytokines at levels consistent with the chronic low-grade inflammation observed in T2D. The most cytokine-sensitive genes were then examined for association of single nucleotide polymorphisms (SNPs) with acute insulin response to glucose (AIRg) measured in the Genetics UndeRlying DIAbetes in HispaNics (GUARDIAN) study. In GUARDIAN, there was evidence of association of AIRg with SNPs in ARAP3 (5q31.3), F13A1 (6p25.3), KLHL6 (3q27.1), NID1 (1q42.3), PAMR1 (11p13), RIPK2 (8q21.3), and STEAP4 (7q21.12). These data support the mouse islet microarray data in detection of seven novel genes with potential importance to islet dysfunction in T2D. To further assess each gene, murine islets were exposed for 48-hrs to the following stressors representing models of beta-cell failure: 20nM rotenone (oxidative stress), 100nM thapsigargin (ER stress), 10pg/ml IL-1B + 20pg/ml IL-6 (cytokines/low-grade inflammation), 28mM glucose (hyperglycemia), or 50uM palmitate + 100uM oleate + 50uM linoleate (lipotoxicity). RT-PCR revealed that F13a1 was downregulated 3.3-fold by cytokines (P<0.05) and 2.6-fold by rotenone (P<0.05), Klhl6 was upregulated 4.3-fold by thapsigargin (P<0.01), Ripk2 was mildly (1.5-3-fold) but significantly upregulated by all stressors (P<0.05), and STEAP4 was profoundly cytokine-sensitive (167-fold upregulation, P<0.01). These findings reveal promising leads in elucidating islet dysfunction during the development of T2D.

Description
The TNF family member TL1A (TNFSF15) co-stimulates several T helper subsets and promotes T cell-dependent models of inflammatory diseases, including inflammatory bowel diseases (IBD) and allergic lung disease. TL1A polymorphisms confer susceptibility to IBD and have been associated with disease severity. In this study, we identified TL1A as a strong inducer of TH9 cell differentiation in vitro. Mechanistically, TL1A induced NF-?B signaling and down-stream STAT6 activation and facilitated cooperative binding of BATF, BATF3, and IRF4 to the Il9 promoter. In vivo, utilizing an adoptive T cell transfer model we demonstrated that TL1A promoted IL-9-dependent, TH9 cell-induced intestinal and lung inflammation and blocking anti-IL-9 antibodies attenuated TL1A-driven mucosal inflammation. Our results demonstrate that TL1A promotes TH9 cell differentiation and function and define a role for IL-9 in TL1A-induced mucosal inflammation. Overall design: 4 samples (2x2)
