GOLPH3 and melanoma: The expression of analyzed proteins in evaluated compartments was divided into two levels based on IRS score for melanoma cells (low: <6 vs. high: ≥6), the number of GOLPH2- and GOLPH3-positive macrophages (<20 vs. ≥20) and the number of GOLPH3-positive fibroblasts (<10 vs. ≥10).
