Metabolic labeling and direct imaging of choline phospholipids in vivo.

Choline (Cho)-containing phospholipids are the most abundant phospholipids in cellular membranes and play fundamental structural as well as regulatory roles in cell metabolism and signaling. Although much is known about the biochemistry and metabolism of Cho phospholipids, their cell biology has remained obscure, due to the lack of methods for their direct microscopic visualization in cells. We...

Imaging Glycosylation In Vivo by Metabolic Labeling and Magnetic Resonance Imaging

Glycosylation is a ubiquitous post-translational modification, present in over 50% of the proteins in the human genome, with important roles in cell-cell communication and migration. Interest in glycome profiling has increased with the realization that glycans can be used as biomarkers of many diseases, including cancer. We report here the first tomographic imaging of glycosylated tissues in li...

In vivo albumin labeling and lymphatic imaging.

The ability to accurately and easily locate sentinel lymph nodes (LNs) with noninvasive imaging methods would assist in tumor staging and patient management. For this purpose, we developed a lymphatic imaging agent by mixing fluorine-18 aluminum fluoride-labeled NOTA (1,4,7-triazacyclononane-N,N',N''-triacetic acid)-conjugated truncated Evans blue ((18)F-AlF-NEB) and Evans blue (EB) dye. After ...

Imaging lipid synthesis in hepatocellular carcinoma with [methyl-11c]choline: correlation with in vivo metabolic studies.

UNLABELLED PET with [methyl-(11)C]-choline (11C-choline) can be useful for detecting well-differentiated hepatocellular carcinoma (HCC) that is not 18F-FDG-avid. This study was designed to examine the relationship between choline metabolism and choline tracer uptake in HCC for PET with 11C-choline. METHODS Dynamic PET scans of 11C-choline were acquired using the woodchuck models of HCC. After...

The Determination of Choline in Phospholipids

The use of reineckate as a precipitating agent in the determination of choline was introduced by Kapfhammer and Bischoff (1). This precipitation was later adapted by Beattie to the calorimetric determination of micro quantities of choline (2). Beattie used a saturated solution of ammonium reineckate in water for the precipitation of choline and stated that the precipitation of choline at temper...
