DHRS2 and granular cell tumor: As a result, stress and apoptosis sensors as well as cell cycle regulators GADD45B, ATF3, ZFP36, DUSP1, FOS, ID2 and CDKN1A were up‐regulated.5 In addition, we identified four genes (DHRS2, RHOB, CRISPLD2, BAIAP2), which were up‐regulated in all GCT cell lines tested as well as the controls (fibroblasts and the Sertoli cell line FS1), suggesting that these genes represent a common effect of romidepsin on gene expression.5 Among all samples analysed, DHRS2 was the most prominently up‐regulated gene.5
