The intensity of AM and AM receptor staining in the gastric cancer tissue samples was scored as 0% (negative), 25% (weak), 50% (moderate), 75% (strong), or 100% (strongest) as determined by a pathologist from ADICON CLINICAL LABORATORIES. (A) Staining showing the expression of AM (left, gastric cancer tissue; right, adjacent tissue). (B) Staining showing the expression of RAMP1 (left, gastric cancer tissue; right, adjacent tissue). (C) Staining showing the expression of RAMP2 (left, gastric cancer tissue; right, adjacent tissue). (D) Staining showing the expression of RAMP3 (left, gastric cancer tissue; right, adjacent tissue). (E) Staining showing the expression of CRLR(left, gastric cancer tissue; right, adjacent tissue).
