We explored the expression of beta‐2 adrenergic receptor (β2‐AR), interleukin 6‐receptor (IL6‐R), cyclooxygenase 2 (COX2) and VEGF‐A by immunohistochemistry in melanoma to assess the correlation between these proteins in melanoma cells and response to treatment. The gene discussed is ADRB2; the disease is melanoma.
