SATB1 Is a Pivotal Epigenetic Biomarker in Cutaneous T-Cell Lymphomas

The SATB1 protein has been the focus of two recent studies of cutaneous T-cell lymphomas. Fredholm et  al. observed a stage-related decrease of SATB1 expression in epidermotropic cutaneous T-cell lymphomas. SATB1 was negatively regulated by STAT5 through microRNA-155, which in turn triggered enhanced expression of T helper type 2 cytokines such as IL-5 and IL-9. In parallel, Sun et al. found that SATB1 expression was up-regulated by promoter demethylation in a subset of cutaneous anaplastic lymphoma and was associated with T helper type 17 polarization in patients with better therapeutic responses.
