Of note, activation of glucocorticoid‐receptor (GR, encoded by NR3C1) downstream signalling was linked to HDACi stimulation in human endometrial Ishikawa cells, although expression of GR was not affected.21NR3C1 is expressed in GCT cell lines and tissues, but not up‐regulated upon romidepsin application, suggesting that romidepsin induces GR signalling downstream targets independent of GR upregulation in GCT cells, too (Figure 3C, Data S1G). The gene discussed is NR3C1; the disease is granular cell tumor.
