The relationship between distant metastasis-free survival and amino acid metabolism-related genes in breast cancer patients. The impacts of amino acid metabolism-related genes on distant metastasis-free survival (DMFS) of breast cancer patients were studied using the KMplot database (n = 1,764). The red colored lines indicate high transcriptional expression levels, whereas the black colored lines indicate low expression levels. The hazard ratios (HRs), with 95% confidence intervals and log-rank P-values, are illustrated. High expression levels of ARG2, CBS, PHGDH, BCAT1, MAT, TDO2, SHMT2, PSAT1, PSPH, MAT2A, GLDC, and ASL predicted poor prognoses. High expression levels of MTHFR, GLUL, MAT2B, TAT, PYCR2, SHMT1, GLS2, PIG6, CTH, BCAT2, GLUD1, and HECA predicted good prognoses.
