Project description:Microarray analysis was performed to evaluate the changes in gene expression that are associated with manf-1 deficiency with and without exposure to tunicamycin. RNA was isolated from four groups, (wildtype (N2) and manf-1 mutant (tm3603) L1 stage larve with and without 5 hours exposure to tunicmycin (5microgram/milliliter)) for transcriptomic profiles analysis

Project description:When C. elegans larvae hatch in the absence of food they persist in a stress resistant, developmentally arrested state (L1 arrest). We characterized mRNA expression genome-wide in a pair of bifurcating time series starting in the late embryo and proceeding through the hatch in the presence and absence of food (E. coli). We used Affymetrix C. elegans expression arrays to measure gene expression in 18 total timepoint/conditions in three biological replicates. Keywords: time course; plus/minus food

We used Affymetrix C. elegans expression arrays to measure gene expression in 18 total timepoint/conditions in three biological replicates. Experiment Overall Design: Nematode populations were staged such that they hatched withing a 2.5 hr window, and time point zero (0 hr) corresponds to when 50% of the population had hatched. RNA was isolated with TRIzol and 100 ng was used for T7 RNA polymerase-based mRNA amplification and biotin labeling using MessageAmp II-Biotin Enhanced kit (Ambion). Labeled cRNA was fragmented, hybridized to the Affymetriz array, and scanned according to the manufacturerâs protocol.

Project description:To find out possible pathways and processes influenced by DmMANF we compared the changes in MANF null and overexpressing animals. We used two developmental stages of Drosophila, st 17 embryos and 29-50 hrs after egg laying (AEL) larvae. The timing were decided according to the lethality of MANF mutants with or without maternal contribution of MANF. Maternal and zygotic MANF mutants (MANFmzD96) were compared to paternal rescue and wild type embryos of the same age. Zygotic MANF mutants (MANFD96) with maternal contribution were compared to wild type and MANF ectopic overexpression larvae harvested well before the average lethality occured (75 hrs AEL). The changes in expression profiles were more drastic in MANFmzD96 embryos than in MANFD96 larvae. Gene ontology annotations were analyzed and clustered by DAVID. The major result was alterations in membranes, changes in membrane transporter expressions and disturbed intracellular membrane traffic. The results were verified by qPCR and transmission electron microscopy.

Two developmental stages - 21-24 hrs and 29-50 hrs AEL of MANFD96 mutants without and with maternal contribution were compared to wild type (Wmix means crossed w1118 x w- ) and with paternal rescue or ectopic overexpression of MANF respectively by Drosophila Agilent microarray expression platform.

Project description:When medaka fish larvae are grown in the absence of exogenous nutrition, the liver becomes dark and positive to Oil Red O staining. We examined the the mechanism of this starvation-induced development of fatty liver by proteomic analysis using livers obtained from larvae grown in the presence or absence of 2% glucose at 5 days-post-hatch.

Project description:This experiment was designed to identify early targets of daf-16/FoxO during L1 starvation in C. elegans. Previous work (Baugh et al 2009) examined temporal dynamics of gene expression in fed and starved L1 larvae using the same platform and methods. Here, a single time point was analyzed (~3 hr after hatching) in fed and starved larvae also comparing wild-type and a daf-16 null mutant. Statistical analysis includes pairwise comparisons between the four conditions as well as a two-factor analysis to explicitly identify genes affected by nutrient availability in daf-16-dependent fashion.

Project description:Purpose: Evaluate transcriptional changes in glioma derived stem cells, U251, and normal human astrocytes following treatment with NH125, Tunicamycin, or 0.1% DMSO Methods: Glioma derived stem cells, U251 and Normal Human Astrocytes were plated in individual dishes and treated with either 2.5 micromolar NH125, 1.0 mcg/mL Tunicamycin, or 0.1% DMSO (vehicle) for twenty-four hours followed by total RNA extraction, library preparation and next generation sequencing Results: Using our analysis pipeline we mapped our sequence reads to the reference genome GRCh38. Following read count normalization and differential expression of NH125 and tunicamycin treated samples to vehicle treated controls we found that NH125 and tunicamycin treatment lead to activation of similar signalling pathways Conclusions: We present an optimized workflow for analysis of transcriptional changes in drug treated glioma derived stem cells, glioblastoma cells and normal human astrocytes

Project description:GPT inhibitor Tunicamycin develops ER stress causing anti-angiogenic response in breast tumor microvasculature due to unfolded protein response-mediated apoptosis. cDNA microarray identified 123 and 454 differentially regulated genes with 10 genes overlapping between 3h and 32 h of Tunicamycin treatment. Alg-2 expression is inconsistent but not the Dpms. Evidences support that Tunicamycin completely destroys DPMS activity in capillary endothelial cells without affecting its protein or the mRNA levels but by knocking down the phosphorylation. DPMS’ contribution to developing upr during ER stress has therefore been evaluated because of its inherent regulatory property of GPT. FTIR spectroscopy confirmed protein denaturation. Restablishing the phosphorylation status helps the DPMS regaining its activity. As a result, ER stress is reduced reversing apoptosis and bringing more cells into cycling with normal cellular morphology. Furthermore, differential expression of DPMS in breast tumor microvasculature during Tunicamycin therapy raises its potential as a tumor prognostic marker in the clinic.

Project description:ER stress could affect many tissues, especially liver, in which non-alcoholic fatty liver disease, liver steatosis, etc. have been reported relative. But there still lack systematic insight into ER stress in liver, which can be obtained by transcriptomics of the tissue. Here, tunicamycin was utilized to induce ER stress in C57BL/6N mice. And microarray was performed to get the transcriptome alteration. Microarray of liver from tunicamycin-injected C57Bl/6N mice
