Project description:Illumina Infinium MethylationEPIC BeadChip (850k) array analysis of DNA methylation of embryonal carcinoma cell lines NCCIT and 2102EP deficient for CD24 and parental cells. CD24 deficiency was genereted by CRISPR/Cas9 method. Three different NCCIT and 2102EP knock out clones were analyzed.
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. 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.

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:Normal, premalignant and various histological subtypes of testicular germ cell tumor (TGCT) tissues were hybridized against Universal Human Reference RNA (Stratagene) onto Agilent 60mer oligo microarrays (GEO accession no GPL885). In vitro time series of two TGCT cell lines, NTERA2 and 2102Ep, treated with retinoic acid for 0, 3, and 7 days were also included. The data set (30 hybridizations) is particularly useful for comparisons between various histological subtypes of TGCT versus each other or versus normal testis.

Project description:Illumina 450k DNA methylation microarray analysis of seminoma-like TCam-2 cells xenografted in nude mice. 2120EP embryonal carcinoma cells served as control. TCam-2 cells acquire pluripotency and become epigenetically reprogrammed to an embryonal carcinoma-like state during in vivo growth. This analysis is part of the article 'BMP inhibition in seminomas initiates acquisition of pluripotency via NODAL signaling resulting in reprogramming to an embryonal carcinoma' by Nettersheim et al., 2015. PLoS Genetics Genomic DNA was isolated from tumors of TCam-2 and 2102EP cells xenografted for 1, 2, 4 and 6 weeks as well as 4 and 8 weeks, respectively. In vivo samples of TCam-2 cells were analyzed in biological duplicates. In vitro cultivated TCam-2 / 2102EP cells as well as 2102EP xenografted for 4 and 8 weeks were analyzed once.
