(Submitter supplied) Breast tumors are characterized by inherent heterogeneity but the evolving cellular organization of breast tumors through progression remains poorly understood. Individual clones were tracked by combining mouse models of breast cancer with Confetti reporter strains. Expression profiling of individual clones sorted from tumors arising in K5- and Elf5-driven Pten/p53-deficient mice revealed distinct molecular signatures.

(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) The mechanisms regulating breast cancer differentiation state are poorly understood. Of particular interest are molecular regulators controlling the highly aggressive and poorly differentiated traits of basal-like breast carcinomas. Here we show that the Polycomb factor EZH2 maintains the differentiation state of basal-like breast cancer cells, and promotes the expression of progenitor-associated and basal-lineage genes. 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) Breast cancer arises from breast epithelial cells that acquire genetic alterations leading to subsequent loss of tissue homeostasis. Several distinct epithelial subpopulations have been proposed, but complete understanding of the spectrum of heterogeneity and differentiation hierarchy in the human breast remains elusive. Here, we used single-cell mRNA sequencing (scRNAseq) to profile the transcriptomes of 25,790 primary human breast epithelial cells isolated from reduction mammoplasties of seven individuals. more...

(Submitter supplied) Tumor evolution from a single cell into a malignant, heterogeneous tissue remains poorly understood. Here, we profiled single-cell transcriptomes of genetically engineered mouse lung tumors at seven stages, from atypical adenomatous hyperplasia to adenocarcinoma. The diversity of transcriptional states increased over time and was reproducible across tumors and mice. Cancer cells progressively adopted alternate lineage identities, computationally predicted to be mediated through a common transitional, high-plasticity cell state (HPCS). more...
