Plasma Metabolomic Profiles in Breast Cancer Patients and Healthy Controls: By Race and Tumor Receptor Subtypes

Abstract: Because of small sample size, the clinical usage of the metabolites from this study is unclear. Further validation of those significant metabolites is warranted, especially with the consideration of racial difference.

“…Surprisingly, we didn't observe lower levels of amino acids especially in the triple negative cell line MDA-MB-231 as observed in human blood plasma samples by Shen et al[40]. Ingeneral, decreased amino acid levels might be a consequence of elevated energy demand in cancer cells which might result in channeling of amino acids into the tricarboxylic acid (TCA) cycle.…”

“…It has great promise for the discovery of novel clinical biomarkers and the elucidation of diseasespecific pathways to improve prognosis, diagnosis and therapy (Brindle et al 2002;Fiehn 2002;Madsen et al 2011;Zhang et al 2013;Shen et al 2013). Metabolomics research is mainly based on mass spectrometry (MS) and/or nuclear magnetic resonance (NMR) spectroscopy combined with multivariate statistics in order to understand and interpret the resulting data ( Van der Greef et al 1983;Nicholson et al 1999;Lindon and Nicholson 2008).…”

“…A decrease of most amino acid levels has been reported in the blood plasma of breast cancer patients [28] and different breast cancer cell lines [29]. Assuming elevated energy consumption and consequent channeling of amino acids into the TCA cycle, Val, Tyr, Phe, Trp, Met, and Leu were decreased in breast cancer in both of the two studies.…”

“…The alteration of metabolites could be a result of genetic, pathological, or environmental changes. As reported, many metabolite levels were altered in the blood plasma and urine of cancer patients or cancer cell lines [24,25,26,27,28,29,30,31]. Metabolic profiling can reveal the alteration of metabolite levels in cancer patients, and, consequently, novel biomarkers could be discovered [32].…”
