Brown and beige adipose tissue are emerging as distinct endocrine organs. These tissues are functionally associated with skeletal muscle, adipose tissue metabolism and systemic energy expenditure, suggesting an interorgan signaling network. Using metabolomics, we identify 3-methyl-2-oxovaleric acid,...
H1299 cells expressing tetracycline regulated (“tet-off”) delta30 p53 (delta364-393) were previously described (Chen et al., 1996; McKinney et al., 2004).
As a control for the effect of thiostrepton on gene expression in Streptomyces coelicolor, cultures of strain M667 [DrelA tipAp::] that lacks the truncated relA gene downstream of the thiostrepton-inducible promoter were treated with thiostrepton. Samples were harvested at 30 min intervals following...
ppGpp synthesis was activated in exponentially growing cells of Streptomyces coelicolor in the absence of amino acid starvation by using a strain (M653 [DrelA tipAp::relA(1.46kb)]) that expresses a truncated portion of relA under the control of a thiostrepton-inducible promoter. Samples were harvest...
Detailed characterization of complex biological surfaces by matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging (MSI) requires instrumentation that is capable of high mass resolving power, mass accuracy and dynamic range. Fourier transform ion cyclotron resonance mass sp...
Neutrophils play a key role in the pathophysiology of rheumatoid arthritis (RA) where release of ROS and proteases directly causes damage to joints and tissues. Neutrophil function is directly affected by Janus Kinase (JAK) inhibitor drugs, including tofacitinib and baricitinib, which are clinically...
