Background: The amino acid transport system L is a major nutrient transport system that is responsible for transport of neutral amino acids, including several essential amino acids. The current study attempted to investigate the expression and functional characterization of amino acid transport system L in HTB-41 human submaxillary salivary gland epidermoid carcinoma cells.
Materials And Methods: RT-PCR analysis, Western blot analysis and amino acid transport measurements were used.
Ethnopharmacological Relevance: Cordyceps militaris, one of traditional herbal ingredient in oriental medicine, has been known to promote anticancer and immunomodulatory activities in vitro and in vivo. However, the biological mechanism of anticancer activity has been unknown.
Objective: To investigate the effect of Cordyceps militaris extract on expression of interferon gamma (IFN-gamma) through interlukin-18 (IL-18) induction and its biological mechanism in vitro and in vivo.
Purpose: 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 which BCH suppresses cell growth in cancer cells.
Methods: The effect of BCH and the mechanism of BCH on cell growth suppression in cancer cells were examined using amino acid transport measurement, MTT assay, DNA fragmentation analysis, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay and immunoblotting.
