Figure 2From: Tumor-dependent increase of serum amino acid levels in breast cancer patients has diagnostic potential and correlates with molecular tumor subtypesAmino acid levels in patients with luminal A or basal-like breast cancer. (A) Blood amino acid levels and (B) principal component (PC) 1 values in the prognostically most (luminal A, n = 19) and least (basal-like, n = 6) favorable molecular subtypes of breast cancer.Back to article page
