Proliferation rate is correlated with the level of many metabolites. (A) Supervised clustering of normalized metabolite levels as ordered by the proliferation rate (Ki-67%) (from low (left) to high (right)). (B) Zoomed views of the metabolites that are most positively (orange bar) or negatively (blue bar) correlated with proliferation. (C) Proliferation associated with receptor status and cancer status from the 30 samples in this study. (D) The correlation of representative metabolites positively or negatively associated with proliferation rate.
