摘要: Mammary gland morphology and physiology are supported by an underlying cellular differentiation hierarchy. Molecular features associated with particular cell types along this hierarchy may contribute to the biological clinical heterogeneity observed in human breast carcinomas. Investigating normal developmental phenotypes tumors provide new prognostic paradigms, identify targetable pathways, explain cancer subtype etiology. We used transcriptomic profiles coming from fluorescence-activated sorted (FACS) mammary epithelial several independent murine studies. Using a meta-analysis approach, we derived consensus gene signatures for both species these relate phenotypes. then compiled dataset of patients treated neoadjuvant anthracycline taxane chemotherapy regimens determine if traits predict likelihood pathological complete response (pCR) multivariate logistic regression analysis markers genomic such as proliferation. Most tumor subtypes shared some, but not all, specific FACS-purified type; thus most potential distinct type ‘origin’ could be assigned. found that luminal progenitor mouse fetal stem predicted pCR sensitivity across all even after controlling intrinsic subtype, proliferation, variables. This work identifies clinically relevant highlights value biology perspective uncovering relationships between their counterparts.
