Further transient transfection of both SK‐MEL‐28 and A375 cell lines led to the expected α‐syn overexpression and further caused a parallel increase of DJ‐1 protein levels, indicating the co‐occurrence of both proteins in melanoma cells (Figure 4B) in agreement with the positive correlation observed in SKCM melanoma patients (Figure 1C). The gene discussed is PARK7; the disease is melanoma.
