Kann, Oliver, Richard Kovács, and Uwe Heinemann. Metabotropic receptor-mediated Ca signaling elevates mitochondrial Ca and stimulates oxidative metabolism in hippocampal slice cultures. J Neurophysiol 90: 613–621, 2003. First published April 30, 2003; 10.1152/jn.00042.2003. Metabotropic receptors modulate numerous cellular processes by intracellular Ca signaling, but less is known about their r...

male breast cancer is a rare disease with an increasing trend. due to limited information especially about the genetic basis of the disease in iran and the lower age of its onset, the disease requires more attention. the aim of this study was to screen the male patients with breast cancer for brca mutations as well as tissue markers of estrogen receptor (er), progesterone receptor (pr), human e...

We have developed a folate receptor-specific activatable probe for in vivo near-infrared fluorescence imaging of ovarian cancer. This probe becomes highly fluorescent only when its linker is cleaved by a tumor-associated lysosomal enzyme cathepsin B after internalization into folate receptor-positive cancer cells.

The stoichiometry and composition of membrane protein receptors are critical to their function. However, the inability to assess receptor subunit stoichiometry in situ has hampered efforts to relate receptor structures to functional states. Here, we address this problem for the asialoglycoprotein receptor using ensemble FRET imaging, analytical modeling, and single-molecule counting with photoa...

We report the implementation and exploitation of fluorescence polarization measurements, in the form of anisotropy fluorescence lifetime imaging microscopy (rFLIM) and energy migration Förster resonance energy transfer (emFRET) modalities, for wide-field, confocal laser-scanning microscopy and flow cytometry of cells. These methods permit the assessment of rotational motion, association and pro...

The ACTOne cannabinoid receptor 1 functional system is comprised of transfected HEK cells with the parental cyclic nucleotide gated channel (CNG) co-transfected with cannabinoid receptor 1 (CB1). The ACTOne CB1 cell line was evaluated for cAMP driven fluorescence by optimizing experimental conditions for sensitivity to forskolin and CP 55,940, reading time point, reliability of cell passage num...

A simple 2-hydroxy-1-naphthaldehyde (receptor 1) serves as a selective chemosensor for Al(3+) based on chelation-enhanced fluorescence (CHEF). The receptor 1 exhibited a high association constant with micromolar detection for Al(3+) in EtOH-H(2)O solution.

Desensitization of G protein-coupled receptors (GPCRs) involves receptor phosphorylation and reduction in the number of receptors at the cell surface. The neuropeptide Y (NPY) Y(1) receptor undergoes fast desensitization. We examined agonist-induced signaling and internalization using NPY Y(1) receptors fused to green fluorescent protein (EGFP). When expressed in HEK293 cells, EGFP-hNPY Y(1) re...
