Transcription profiling of human normal, premalignant and various histological subtypes of testicular germ cell tumor (TGCT) tissues, and of two TGCT cell lines treated with retinoic acid

ABSTRACT: 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.

Data were imported from their GEO record, which contains no information about which dyes were scanned in which channels. CH1 and CH2 have therefore been used throughout.

Embryonal carcinoma is a histologic subgroup of testicular germ cell tumors (TGCTs), and its cells may follow differentiation lineages in a manner similar to early embryogenesis. To acquire new knowledge about the transcriptional programs operating in this tumor development model, we used 22k oligo DNA microarrays to analyze normal and neoplastic tissue samples from human testis. Additionally, retinoic acid-induced in vitro differentiation was studied in relevant cell lines. We identified genes  ...[more]
