ABSTRACT
Objective To assay free amino acids (FAA) content of breast cancer tissue and mammary glandular tissue and discuss the therapeutic basis of unbalanced amino acids of breast cancer. Methods The selected samples were conserved and then cut into pieces, grinded, syruped and deproteinized. Then FAA were separated from the samples. The content of 17 kinds of free amino acids in breast cancer tissue and mammary glandular were assayed respectively. Results The concentration of FAA in breast cancer tissue was higher than that in mammary glandular tissue. Conclusions Free amino acids metabolism was greatly different in breast cancer and mammary glandular tissues. This offers a therapeutic basis for the treatment of unbalanced free amino acids in the case of breast cancer.
