BACKGROUND The amino acid transport system L is a major nutrient transport system responsible for Na(+)-independent transport of neutral amino acids, including several essential amino acids. The system L is divided into two major subgroups, the L-type amino acid transporter 1 (LAT1) and the L-type

The relatively broad and overlapping specificities of amino acid transport systems have made the synthesis of analogues specific to single transport systems desirable. The analogue in general use as a specific substrate for transport system L has been 2-aminobicyclo[2.2.1]heptane-2-carboxylic acid

We investigated the antitumoral activity of Dabis Maleate given on different dosage schedules and as continuous infusion in a murine reticular cell sarcoma M5076 (M5) and in a subline made resistant to cyclophosphamide and other nitrogen mustards (M5/CTX). The therapeutic index of Dabis Maleate was

Amino acids, especially essential amino acids are required for protein synthesis and as energy sources in all living cells. Since most amino acids are hydrophilic, special membrane proteins are necessary for their transmembrane transport particularly in transformed cells. We cloned a cDNA encoding

OBJECTIVE L-Type amino acid transporter 1 (LAT1) is highly expressed in cancer cells to support their continuous growth and proliferation. We have examined the effect of 2-aminobicyclo-(2,2,1)-heptane-2-carboxylic acid (BCH), an inhibitor of system L amino acid transporters, and the mechanism by
