Project description:We isolated Osr1-expressing cells (Osr1 GCE/+) via FACS-sorting from E13.5 axillary, inguinal and cervical regions of a mouse embryo and analysed the gene expression profile of 10,000 cells through single-cell RNA-seq.
Project description:In this study we focussed our investigations on ECM remodelling by FRCs during lymph node (LN) expansion, and the interconnection between the cellular and ECM components of the conduit network. We demonstrate a loss of ECM components of the conduit during acute LN expansion
Project description:Breast cancer is the most common malignancy that develops in women, responsible for the highest cancer-associated death rates. Triple negative breast cancers (TNBC) represent an important subtype that have an aggressive clinical phenotype, are associated with a higher likelihood of metastasis and are not responsive to current targeted therapies. miRNAs have emerged as an attractive candidate for molecular biomarkers and treatment targets in breast cancer, but their role in the progression of TNBC remains largely unexplored. This study has investigated miRNA expression profiles in 31 primary TNBC cases and in 13 lymph node metastases compared with 23 matched normal breast tissues to determine miRNAs associated with the initiation of this disease subtype and those associated with its metastasis. 71 miRNAs were differentially expressed in TNBC, the majority of which have previously been associated with breast cancer, including members of the miR-200 family and the miR-17-92 oncogenic cluster, suggesting that miRNAs involved in the initiation of TNBC are not subtype specific. However, the repertoire of miRNAs expressed in lymph node negative and lymph node positive TNBCs were largely distinct from one another. In particular, miRNA profiles associated with lymph node negative disease tended to be up-regulated, while those associated with lymph node positive disease were down-regulated and largely overlapped with the profiles of their matched lymph node metastases. miRNA expression profiles were examined in 31 primary TNBC cases and in 13 lymph node metastases compared with 23 matched normal breast tissues

Project description:A classifier was build on 82 training samples to differentiate between lymph node negative (N0) and lymph node metastasis (N+) head and neck squamous-cell carcinomas (HNSCC). The 102 predictor genes that resulted from this classifier where then validated against a independent validation set.
Project description:Gene expression in the top, light and heavy polysome fractions of Eif4g3 siRNA treated lymph node stromal cells (LNSCs) compared to control-sIRNA treated samples This study was performed to examine whether the expression of certain genes in LNSCs is regulated by the translation factor, eukaryotic translation initiation factor 4 gamma 3 (Eif4g3).
Project description:This SuperSeries is composed of the following subset Series: GSE29152: Lymph node stromal cells: Control siRNA treated vs. Eif4g3 siRNA treated GSE29153: Differential gene expression in the Pancreatic lymph node of Deaf1 knockout mice vs. wild type littermate controls Refer to individual Series
