GRP and skin basal cell carcinoma: In BCC tumors, a clear difference is observed between cGRP (Figures 7(b) and 7(c)) and ucGRP (Figures 7(f) and 7(g)) accumulation associated with tumor cells (TC): staining for cGRP was decreased compared to ucGRP, while in healthy skin areas adjacent to tumors, both GRP forms are similarly accumulated (Figures 7(d) and 7(h)) with a pattern comparable to control skin (Figures 7(a) and 7(e)).
