Glycolysis is one of the most important metabolic pathways in heterotrophic organisms. Several genes encoding glycolytic enzymes are essential in many bacteria even under conditions when neither glycolytic nor gluconeogenic activities are required. In this study, a screening for in vivo interaction partners of glycolytic enzymes of the soil bacterium(More)
The cytokine macrophage migration inhibitory factor (MIF) exhibits pro- and anti-inflammatory activities and regulates cell proliferation and survival. We investigated the effects of MIF on apoptosis. As MIF exhibits oxidoreductase activity and participates in regulating oxidative cell stress, we studied whether MIF could affect oxidative stress-induced(More)
The present study evaluates the relation between loudness and simple reaction time (RT). Loudness matches between a narrowband noise (125 Hz wide) and a broadband noise (1500 Hz) were made at levels from near threshold to near 100 dB SPL. Over a similarly wide range of levels, RT to each of the noise bands was also measured. As reported often in previous(More)
We have reported earlier that T cells found in the tumor microenvironment of head and neck cancer showed evidence of apoptosis as well as decreased expression of signaling molecules. In this prospective study, spontaneous apoptosis in tumor-infiltrating lymphocytes (TILs) and in paired circulating peripheral blood lymphocytes (PBLs) was evaluated in 28(More)
RATIONALE Transverse tubules (TTs) couple electric surface signals to remote intracellular Ca(2+) release units (CRUs). Diffraction-limited imaging studies have proposed loss of TT components as disease mechanism in heart failure (HF). OBJECTIVES Objectives were to develop quantitative super-resolution strategies for live-cell imaging of TT membranes in(More)
T cells with specificity for antigens derived from Wilms Tumor gene (WT1), Proteinase3 (Pr3), and mucin1 (MUC1) have been demonstrated to lyse acute myeloid leukemia (AML) blasts and multiple-myeloma (MM) cells, and strategies to enhance or induce such tumor-specific T cells by vaccination are currently being explored in multiple clinical trials. To test(More)
RATIONALE Monitoring and controlling cardiac myocyte activity with optogenetic tools offer exciting possibilities for fundamental and translational cardiovascular research. Genetically encoded voltage indicators may be particularly attractive for minimal invasive and repeated assessments of cardiac excitation from the cellular to the whole heart level. (More)
Aminopeptidases catalyze the cleavage of amino acids from the amino terminus of protein or peptide substrates. Although some aminopeptidase activities have been found in plant chloroplasts, the identity of these proteins remains unclear. In this work, we report the purification to apparent homogeneity of a soluble aminopeptidase from isolated barley(More)
A hallmark of mature mammalian ventricular myocardium is a positive force-frequency relationship (FFR). Despite evidence of organotypic structural and molecular maturation, a positive FFR has not been observed in mammalian tissue engineered heart muscle. We hypothesized that concurrent mechanical and electrical stimulation at frequencies matching(More)
