Project description:SOX2 is an oncogene and a core pluripotency transcription factor. SOX2 has multiple roles in various malignancies, in the maintenance of pluripotency and during various stages of embryonic development. Human embryonal carcinoma cells express SOX2 and the loss of this results in their differentiation. We silenced SOX2 in two human embryonal carcinoma cell lines and measured the differential expression of 754 unique mature miRNAs. This revealed the deregulation of many oncomiRs, tumour suppressor miRNAs and developmental miRNAs, including those belonging to the C19MC cluster.
Project description:SOX2 is an oncogene and a core pluripotency transcription factor. SOX2 has multiple roles in various malignancies, in the maintainance of pluripotency and during various stages of embryonic development. Human embryonal carcinoma cells express SOX2 and the loss of this results in their differentiation. We silenced SOX2 in two human embryonal carcinoma cell lines and measured whole-genome mRNA expression. Many genes related to embryogenesis and tissue morphogensis were upregulated. Other upregulated genes were markers of mesodermal development and epithelial-to-mesenchymal transition.

We silenced SOX2 in two human embryonal carcinoma cell lines and measured whole-genome mRNA expression. Many genes related to embryogenesis and tissue morphogensis were upregulated. Other upregulated genes were markers of mesodermal development and epithelial-to-mesenchymal transition. A specific and validated siRNA against SOX2 was chemically transfected in undifferentiated 2102Ep and NTera-2 embryonal carcinoma cell lines. After three days of incubation under normal growth conditions we used Affymetrix microarrays to measure whole-genome mRNA transcript expression in three biological replicates of each cell line and compared this to whole-gene expression in identical samples transfected with a non-targeting, scrambled control siRNA. SOX2 silencing was validated using qRT-PCR and Western blot prior to whole-genome expression analysis.
Project description:Membrane proteins play critical roles between the tumor cells and the extra-cellular matrix (ECM) during metastasis. In this study, we performed quantitative proteomic analysis of membrane proteins from two human giant-cell lung carcinoma cell strains, low- (95C) and high-(95D) metastatistic cell lines, and combining with microRNA analysis, we identified a multi-omics regulation module.
Project description:Illumina expression microarray analysis of seminoma-like TCam-2 cells depleted for SOX2 by CRISPR/Cas9. Cells were xenografted in nude mice. 2120EP embryonal carcinoma and parental TCam-2 cells were xenograted as controls. Tumors were recovered after 1 (1w) and 6 weeks (clone 1 - 5) of in vivo growth. Additionally, in vitro cultivated TCam-2 were analyzed as control. The data set is part of the study 'SOX2 is essential for in vivo reprogramming of seminoma-like TCam-2 cells to an embryonal carcinoma-like fate' (Nettersheim et al., 2016, Oncotarget).
