Gene signatures and potential therapeutic targets of amino acid metabolism in estrogen receptor-positive breast cancer.

ABSTRACT: Increased activity of amino acid transporters has been observed in a wide variety of cancers. However, whether amino acid metabolism is related to estrogen receptor-positive (ER+) breast cancer has been less well studied. We identified the rate-limiting enzyme involved in amino acid metabolism associated with ER+ breast cancer by integrating numerous bioinformatics tools and laboratory studies. The bioinformatics analysis revealed that highly expressed genes in ER+ breast cancer patients were correlated with breast cancer-related pathways, including ESR1 and PI3K signaling. The metabolic signaling and the amino acid metabolism were significantly regulated in breast neoplasms. We used the ER+ breast cancer cell line MCF-7 and breast cancer tissue from National Cheng Kung University Hospital
