Transcription profiling of mouse C2C12 myotubes treated overnight with 500 uM palmitate or 1% bovine serum albumin control to identify mediators of obesity-linked reductions in PGC-1

Project description:To identify mediators of obesity-linked reductions in PGC-1, we tested the effects of cellular nutrients in C2C12 myotubes. While overnight exposure to high insulin, glucose, glucosamine, or amino acids had no effect, saturated fatty acids (FA) potently reduced PGC-1a and b mRNA expression. Experiment Overall Design: Cell culture - Mouse C2C12 myoblasts (ATCC, Manassas, VA) were maintained in Dulbecco's modified Eagle's medium (DMEM) supplemented with 20% fetal bovine serum (Invitrogen), at a confluency of 60-70%. To initiate differentiation, cells were allowed to reach 100% confluency and medium was changed to DMEM containing 2% horse serum (Invitrogen) and changed every 2 days. Full differentiation, with myotube fusion and spontaneous twitching, was observed at 5 days. Fatty acid stock preparation - Fatty acids were dissolved in 0.1 N sodium hydroxide (final concentration 100 mM) at 65 degrees C for 2 hours and then complexed with 10% fatty acid-free BSA, yielding a final stock of 5 mM. Three replicates for each fatty-acid. Microarray analysis - RNA was isolated as described from C2C12 myotubes treated overnight with 500 uM palmitate or 1% BSA, and cRNA was synthesized. 10 mg of cRNA were hybridized to Affymetrix mouse 430A 2.0 arrays. Intensity values were quantified using MAS 5.0 software. MAPPFinder (www.genmapp.org) was used to integrate expression data with known pathways.

Control and starved myotubes

Project description:C2C12 mouse myoblasts (American Type Culture Collection, Manassas, VA) were maintained in growth medium (DMEM supplemented with 10% Fetal Bovine serum, Invitrogen Corporation, Carlsbad, CA) in 5% CO2. Cells were plated at a density of 40-50% in 100mm dishes. When cells reached ~90% confluency 24 hours later, they were switched to differentiation media (DMEM containing 2% horse serum; GIBCO, Invitrogen Corporation, Carlsbad, CA) which was subsequently changed every 48 hours. All cells were allowed to differentiate for 4 days with feeding every two days (day 0, 2, and 4). Beginning at day 4, control cells were re-fed every 48 hours whereas experimental cells were not re-fed. After an additional 4 days (8 days post differentiation), cells were harvested and total RNA was isolated from control and "starved" (non re-fed cells) Keywords: repeat sample

The impact of exposure to serum lipids during in vitro culture on the transcriptome of bovine blastocysts

Project description:EtOH-Lipid form serum have been added in BSA-supplemented SOF during post-compaction development of IVP bovine embryos. Lipid-treated blastocysts were compared with control treated blastocysts (no lipid addition to BSA, EtOH balanced).

Comparison of gene change in lymphoma cells after co-culture with endothelial cells

Project description:Mouse lymphoma cells were co-cultured with endothelial cells in serum/cytokine-free condition. To identify specific genetic changes, we compared lymphoma cells cultured in medium containing 10% fetal bovine serum with lymphoma cells co-cultured with endothelial cells.

Transcriptome changes during the differentiation of myoblasts into myotubes

Project description:This study aimed to interrogate the interrelationship between 3D genome organization and global gene expression during muscle development using a mouse C2C12 cell line as an in vitro model. The C2C12 cell line is a well-established and extensively studied in vitro model derived from serial passage of myoblasts cultured from the thigh muscle of C3H mice after a crush injury. C2C12 cells divide when mitogens are present in the culture medium and spontaneously differentiate into muscle-like multinucleated (myotubes) cells if the medium is depleted of mitogens (i.e. serum; (Bischoff 1986)). C2C12 cells were either harvested as: 1) proliferating myoblasts (Myoblasts); 2) myotubes that were not treated with AraC (as such these myotubes contained myoblasts) - Myotubes(Day3); or 3) myotubes which were treated with AraC (myoblasts were largely depleted from these myotube cultures; Myotubes(Day7+AraC).

Transcriptome analysis of J774A.1 macrophages undergoing amino acid deprivation

Project description:Phagocytosis represents a mechanism used by macrophages to remove pathogens and cellular debris. Recent evidence suggested that amino acid or glucose deprivation may cause an increase in phagocytosis of heat-inactivated Escherichia coli and Staphylococcus aureus by macrophages, but not the uptake of platelets, apoptotic cells or beads. Increased phagocytosis of bacteria could be blocked by phagocytosis inhibitors and depended on p38 MAP kinase activity. To examine potentially important downstream pathways linked to EBSS-induced starvation and p38 MAP kinase activation, a full genome microarray representing over 41,000 mouse genes or transcripts was probed with cDNA isolated from J774A.1 macrophages that were treated with EBSS, EBSS supplemented with the p38 inhibitor SB202190 or control medium supplemented with 10% fetal bovine serum. Keywords: autophagy, heterophagy, p38 MAP kinase, scavenger receptor A, starvation Prior to RNA isolation, J774A.1 macrophages were incubated in RPMI 1640 medium supplemented with (i) 10% fetal bovine serum, (ii) Earleâs Balanced Salt Solution (EBSS) or (iii) EBSS supplemented with 10 ÂµM SB202190 for 6 hours.
