(Submitter supplied) The breast is a dynamic organ whose response to physiological and pathophysiological conditions alters its disease susceptibility, yet the specific effects of these clinical variables on cell state remain poorly annotated. We present a unified, high-resolution breast atlas by integrating single-cell RNA-seq, mass cytometry, and cyclic immunofluorescence, encompassing a myriad of states. We define cell subtypes within the alveolar, hormone-sensing, and basal epithelial lineages, delineating associations of several subtypes with cancer risk factors, including age, parity, and BRCA2 germline mutation. more...

(Submitter supplied) RNA samples were prepared from freshly sorted mammary cell subpopulations (MaSC/basal-enriched, luminal progenitor, mature luminal and stromal) from five sets of adult mice. High throughput RT-PCR was used to measure the global microRNA expression profiles of each cell subpopulation. The expression profiles were compared between cell subpopulations to gain insight into the regulation of lineage-restricted genes.

(Submitter supplied) Cancer metabolism adapts the metabolic network of its tissue-of-origin. However, breast cancer is not a disease of a singular origin. Multiple epithelial populations serve as the culprit cell-of-origin for specific breast cancer subtypes, yet our knowledge of the metabolic network of normal mammary epithelial cells is limited. Using a multi-OMIC approach, here we identify the diverse metabolic programs operating in normal mammary populations. more...

(Submitter supplied) Aging of the mammary gland is closely associated with increased susceptibility to breast cancer, yet there have been limited systematic studies of aging-induced alterations within this organ. Here we leveraged the power of high-throughput single-cell RNA-sequencing (scRNA-seq) to generate a detailed transcriptomic atlas of young and aged murine mammary tissues, including both epithelial and stromal cell types. more...

(Submitter supplied) Mammary organoids treated with a 28 day menstrual cycle profile of estradiol and progesterone with or without TPA: Comparison of normal versus BRCA1 mut cells. Purpose: The goals of this study are to determine 1) the effects of a 28 day menstrual cycle profile of estradiol and progesterone, 2) the effects of TPA, and 3) the responses in normal versus BRCA1 carriers, in benign breast organoids using RNA-seq

(Submitter supplied) BRCA2 mutation carriers preferentially develop luminal-like breast cancers, but it remains unclear how BRCA2 mutations affect mammary epithelial subpopulations. Here, we report that Brca2mut/WT mammary organoids subjected to replication stress activated a transcriptional response that selectively expands Brca2mut/WT luminal cells lacking hormone receptor expression (HR-). While CyTOF analyses revealed comparable epithelial compositions among wildtype and Brca2mut/WT mammary glands, Brca2mut/WT HR- luminal cells exhibited greater organoid formation and preferentially survived and expanded under replication stress. more...

(Submitter supplied) The mammary epithelia are mainly composed of two distinct lineages, the basal and luminal cells. In our MMTV-Cre; Brca1flox/flox mouse model, we found the Brca1 knockout mainly occurred in the luminal cells, which will lead the mammary tumorigenesis. To investigate the Brca1 deficiency mediated mammary tumorigenesis, we sorted the luminal cells from wild type mice and MMTV-Cre; Brca1flox/flox mice for RNAseq analysis.

(Submitter supplied) Brca1 mutation predisposes women to early onset of breast and ovarian cancers.Through its diverse functions in DNA damage repair, cell cycle control, transcription regulation, ubiquitination and so on, BRCA1 acts as a very significant tumor suppressor and genomic safeguard. Brca1 deficiency induces severe cellular stress, when occurring in the mammary glands, it impairs the regular developmental process and eventually causes tumorigenesis due to accumulation of genome instability and other mechanisms. more...

(Submitter supplied) Background: Heterogeneity within the mouse mammary epithelium has been recently explored by single-cell RNA profiling. To further understand how cellular diversity changes during mammary development, we profiled single cells from different developmental stages including late embryogenesis, early postnatal, prepuberty, resting adult, mid-pregnancy, late-pregnancy, lactation and post-involution. We also compared the transcriptomes and chromatin accessibility of micro-dissected ducts versus terminal endbuds (TEBs) to help decipher the molecular properties of these specialized units that drive morphogenesis. more...
