Expression of FGFR3 in melanoma tissues. a the mRNA level of FGFR3 in malignant melanoma tissues and corresponding adjacent normal tissues was evaluated by qRT-PCR (n = 4, **p < 0.01); b FGFR3 protein expression in melanoma tissues obtained from 42 patients was detected by immunohistochemical staining. The FGFR3 staining was categorized as weak, moderate, or strong (upper row, 40x), which were further magnified (lower row, 200x). The FGFR3 expression levels were used to evaluate the relationship between FGFR3 expression and the clinicopathological parameters of the malignant melanoma patients
