RNA sequencing of mammary glands from 55-day old control, MTB-200ba429, MTB-IGFIR, MTB-IGFIRba429 mice.

ABSTRACT: RNA was isolated from mammary glands from 55 day old control mice, mice overexpressing the miR-200b/200a/429 cluster in mammary epithelial cells (MTB-200ba429) mice overexpressing the IGF-IR transgene in mammary epithelial cells (MTB-IGFIR), and mice overexpressing both the miR-200b/200a/429 cluster and the IGF-IR transgene in mammary epithelial cells (MTB-IGFIRba429)

Mammary Tissue: Wild type mammary glands vs IGF-IR induced mammary tumors vs IGF-IR independent tumors

Project description:Molecular profiling was used to classify mammary tumors that develop in MTB-IGFIR transgenic mice. It was determined that the primary mammary tumors (PMT), which develop due to elevated expression of the type I insulin-like growth factor receptor (IGF-IR) in mammary epithelial cells, most closely resemble murine tumors with basal-like or mixed gene expression profiles and with human basal-like breast cancers. Downregulation of IGF-IR transgene in MTB-IGFIR tumor-bearing mice leads to the regression of most of the tumors followed by tumor re-appearance in some of the mice. These tumors that re-appear following IGF-IR transgene downregulation do not express the IGF-IR transgene and cluster with murine mammary tumors that express a mesenchymal gene expression profile and with human claudin-low breast cancers. Therefore, IGF-IR overexpression in murine mammary epithelial cells induces mammary tumors with primarily basal-like characteristics while tumors that develop following IGF-IR downregulation express a gene signature that most closely resembles human claudin-low breast tumors.

The miR-200b/200a/429 cluster prevents metastasis and induces dormancy in murine claudin-low mammary tumor cells

Project description:The miR-200 family of microRNAs consisting of miR-141, miR-200a, miR-200b, miR-200c and miR-429 are key regulators of breast cancer progression. The miR200 family maintains mammary epithelial identity and downregulation of miR-200 expression drives the epithelial-to-mesenchymal transition. Re-expression of one or more miR-200 family members in tumor cells with mesenchymal characteristics may restore the epithelial phenotype and alter growth and metastatic potential. To test this, the miR-200b/200a/429 cluster was re-expressed in a murine claudin-low mammary tumor cell line, RJ423

microRNA expression profile in endometrioid endometrial carcinoma (EEC)

Project description:The aim of the presented study was to define tissue and plasma miRNA signatures, which could potentially serve as diagnostic and prognostic markers in endometrioid endometrial cancer (EEC), and to investigate miRNA profiles in regard to clinicopathological characteristics of the tumors. Results: qPCR validation revealed regulation of 14 miRNAs in EEC tissues (miR-9, miR-141,miR-205,miR-203,miR-183,miR-200a*,miR-200b*,miR-200a,miR-200c,miR-429,miR-200b,miR-410,miR-92a,miR-1305) and 9 in plasma samples (miR-449a,miR-1290,miR-1228,miR-203,miR-200a,miR-141,miR-92a, miR-9, miR-301b). Expression of certain miRNAs showed association with FIGO stage, grade and relapse. Two miRNA signatures, miR-205/miR-410 and miR-410/miR-429/miR-92a, classified tumor tissues with higher accuracy in comparison to single miRNAs (AUC 0.972, 95% CI 0.919-0.995 and 0.991, 95% CI 0.948-1.000, resepctively). miRNA signature composed of miR-205 and miR-200a predicted relapse with AUC of 0.854 (95% CI 0.691-0.951). Tissue miRNA signatures were independent prognostic markers of overall (miR-1228/miR-200c/miR-429, HR 2.98) and progression-free survival (miR-1228/miR-429, HR 4.149). Plasma miRNA signatures classified EEC plasma samples with high accuracy. Conclusions: We conclude that miRNA signatures hold great promise for becoming non-invasive biomarkers for early EEC detection and prognosis.
