" /> Carbon C 11 Methylaminoisobutyrate - CISMeF





Preferred Label : Carbon C 11 Methylaminoisobutyrate;

NCIt synonyms : 11C-MeAIB; N-methyl-11C-methylaminoisobutyric Acid;

NCIt definition : A synthetic neutral amino acid analog radiolabeled with carbon C 11 with potential use for metabolic tumor imaging during positron emission tomography (PET). Upon administration, carbon C 11 methylaminoisobutyrate ([(11)C]MeAIB) is taken up by and accumulates in cancer cells through the A-type (alanine-preferring) amino acid transport system. Upon imaging of the radioisotope, the distribution patterns of MeAIB and its uptake by cancer cells can be further elucidated. This may establish its usefulness as a tumor tracer in the diagnosis of certain cancers. Amino acid transport system A is highly upregulated in malignant cells and facilitates the uptake of amino acids needed for tumor cell proliferation.;
