(Submitter supplied) Using cross-species analysis, we have previously shown that the miR-137 and the miR-23b microRNA cluster are upregulated in the more aggressive and metastatic, mouse and human, primary tumors, designated as met-like primary (MLP). In order to identify miRNA target genes, we overexpressed the miRNAs in an inducible manner in the insulinoma-like ßTC3 cells and performed RNA-seq.

(Submitter supplied) Pancreatic neuroendocrine tumor (PanNET) is relatively infrequent but is nevertheless metastatic. Seeking to extend a new paradigm of personalized medicine, we performed an integrative analysis of transcriptomic (mRNA and microRNA) and mutational profiles and defined three clinically relevant human PanNET subtypes. Importantly, cross-species analysis revealed two of these three subtypes in a well-characterized, genetically engineered mouse model (RIP1-Tag2) of PanNET and its cell lines. 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) RNA samples were prepared from freshly sorted mammary cell subpopulations (MaSC/basal-enriched, luminal progenitor, mature luminal and stromal) from five human donors. 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) Purpose: Pancreatic neuroendocrine tumors (PanNETs) have considerable malignant potential. Frequent somatic mutations and loss of DAXX protein expression have been frequently found in PanNETs. DAXX is known as a transcriptional repressor, however, molecular functions underlying loss of DAXX remain unclear in PanNETs. Experimental Design: We evaluated DAXX-knockdown (KD) and -knockout (KO) PanNET cells were analyzed for in vitro and vivo. more...

(Submitter supplied) We profiled primary breast cancer, nodal and liver metastatic tumours from three patients. At the time of initial diagnosis, all three patients presented with luminal breast cancer with adjacent nodal metastasis. They all received 5 years of enodrine therapy and all subsequently developed liver metastasis.

(Submitter supplied) Pancreatic neuroendocrine tumors (PanNETs) are a heterogeneous group of tumors that exhibit an unpredictable and broad spectrum of clinical presentations and biological aggressiveness. Surgical resection is still the only curative therapeutic option for localized PanNET but the majority of patients are diagnosed at an advanced and metastatic stage with limited therapeutic options. Key factors limiting the development of new therapeutics are the extensive heterogeneity of PanNETs and the lack of appropriate clinically relevant models. more...

(Submitter supplied) Background and Aims Small intestinal neuroendocrine tumours (SINETs) are the commonest malignancy of the small intestine; however underlying pathogenic mechanisms remain poorly characterised. Whole genome and exome sequencing has demonstrated that SINETs are mutationally quiet with the most frequent known mutation in the cyclin dependent kinase inhibitor 1B gene (CDKN1B) occurring in only ~8% of tumours, suggesting that alternative mechanisms may drive tumourigenesis. more...

(Submitter supplied) Background: Human breast cancer is a heterogeneous disease consisting of multiple molecular subtypes. Genetically engineered mouse models (GEMMs) are useful resources for studying breast cancers in vivo under genetically controlled and immune competent conditions. Identifying murine models with conserved human tumor features will facilitate etiology determinations, highlight the effects of mutations on pathway activation, and improve preclinical drug validation. more...

(Submitter supplied) Previous studies reported that mice living in an enriched environment (EE) showed reduced growth of melanoma, colon and breast tumors. Our study extended the potential anti-tumor effect of EE exposure to pancreatic cancer, and firstly provided evidence demonstrating that EE exposure significantly inhibits tumor growth in a syngeneic murine model of pancreatic cancer. To further investigate the mechanisms underlying the EE-induced pancreatic tumor inhibition, we analyzed the gene expression changes in pancreatic tumor xenograft using an integrative transcriptomic and proteomic approach. more...

(Submitter supplied) We report the single-cell RNA-seq based identification of 6 known human islet cell types (alpha cells, beta cells, delta cells, pp cells, acinar cells and duct cells) based on the expression of known marker genes. We further assess cell type specific gene expression and suggest novel marker genes for several cell types.

(Submitter supplied) Pancreatic neuroendocrine tumors (PanNETs) are a heterogeneous population of neoplasms that arise from hormone-secreting islet cells of the pancreas and have increased markedly in incidence over the past four decades. Non-functional PanNETs, which occur more frequently than hormone-secreting tumors, are often not diagnosed until later stages of tumor development and have poorer prognoses. Development of successful therapeutics for PanNETs has been slow, partially due to a lack of diverse animal models for pre-clinical testing. more...

(Submitter supplied) Most pancreatic neuroendocrine tumors (PNETs) do not produce symptoms of hormonal excess and are hence considered ‘non-functional’. Their clinical behaviors vary widely, emphasizing the need for a robust classification with prognostic power. Using enhancer maps to infer regulatory programs, we find that the large majority of non-functional PNETs fall into two major sub-types –A and B– that reflect alpha and beta endocrine cell ontogeny, respectively. more...
