Molecular Imaging and Quantitative Profiling of Fatty Acid Synthase with a Chemical Probe.

Summary of "Molecular Imaging and Quantitative Profiling of Fatty Acid Synthase with a Chemical Probe."

Cancer cells rely on fatty acid synthase (FASN), a key enzyme for biosynthesis of long chain fatty acids, to sustain their proliferative potential and drive invasion. Unfortunately, conventional FASN assays are technically inadequate for discerning otherwise elusive FASN activity in complex biological milieux, which has hindered progress in the functional study of FASN and development of its inhibitors. Here, we describe a chemical probe with unprecedented selectivity and sensitivity for the labelling of active FASN in living cells, thus demonstrating a new analytical modality for visualizing endogenous FASN activity and exploring opportunities for drug discovery.

Medical and Biotech [MESH] Definitions

Animal form of fatty acid synthase which is encoded by a single gene and consists of seven catalytic domains and is functional as a homodimer. It is overexpressed in some NEOPLASMS and is a target in humans of some ANTINEOPLASTIC AGENTS and some ANTI-OBESITY AGENTS.

The form of fatty acid synthase complex found in BACTERIA; FUNGI; and PLANTS. Catalytic steps are like the animal form but the protein structure is different with dissociated enzymes encoded by separate genes. It is a target of some ANTI-INFECTIVE AGENTS which result in disruption of the CELL MEMBRANE and CELL WALL.

The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.

Compounds that interfere with FATTY ACID SYNTHASE resulting in a reduction of FATTY ACIDS. This is a target mechanism in humans of some ANTINEOPLASTIC AGENTS and ANTI-OBESITY AGENTS and of some ANTI-INFECTIVE AGENTS which interfere with CELL WALL and CELL MEMBRANE formation.

Animal form of fatty acid synthase which is encoded by a single gene and consists of seven catalytic domains and is functional as a homodimer. It is overexpressed in some NEOPLASMS and is a target in humans of some ANTINEOPLASTIC AGENTS and some ANTI-OBESITY AGENTS.
