Objective To investigate the relationship of fascin-1 protein expression with the metastasis of basal cell carcinoma and squamous cell carcinoma. Methods Skin specimens were obtained from 10 normal human controls, 13 patients with basal cell carcinoma (8 nodular variant and 5 superficial variant) and 24 patients with SCC (11 SCC in situ and 13 invasive SCC). Immunohistochemical staining was performed to analyze the expression of fascin-1 protein. The staining results were quantitatively assessed with computer image analysis system (Image-pro Plus 6.0). Results The optical density of fascin-1 averaged 0.1152±0.04574 in SCC in situ, 0.1257±0.03096 in invasive SCC, and 0.0293±0.00981 in normal controls; the expression of fascin-1 was significantly higher in SCC tissue than in normal control skin (both P<0.05). Increased optical density was also observed for fascin-1 in nodular variant of SCC (0.0808 ±0.05642) and superficial variant of SCC (0.0806±0.04346) compared with the normal controls, whereas no statistical difference was observed between nodular and superficial variant of SCC. Conclusion In BCC and SCC, there is an over expression of fascin-1, which may be linked to the local invasion of carcinoma,

Objective To study the influence of CYP3A5 genetic polymorphism on tacrolimus metabolism in renal transplantation recipients and evaluate the methods of detecting CYP3A5* 3 polymorphism. Methods Ninety-seven renal recipients receiving the triple immunosuppressive (tacrolimus + mycophenolate mofetil + prednison) were genotyped for CYP3A5* 3 polymorphisms by the Pyrosequencing TM assays. Tacrolimus trough concentration of the patients was measured by enzyme multiplied immunoassay technique, and concentration/adjusted dose ratio (C/D) was investigated at the 7th day, 14th day, 1st month, 3rd month and 6th month after renal transplantation. Results The Pyrosequencing TM assays allowed for quick and accurate detection of CYP3A5* 3 genotypes. There were CYP3A5* 1/* 1 genotype in 17 cases (17. 5%), * 1/* 3 in 35cases (36. 1 %) and *3/* 3 in 45 cases (46.4 %) identified in 97 renal recipients. The C/D of CYP3A5 * 1/* 1 and * 1/* 3 patients was significantly lower than that of * 3/* 3 patients (P<0. 01)after renal transplantation. Conclusion The CYP3A5* 3 polymorphisms are significantly correlated with tacrolimus pharmacokinetic in renal transplant recipients. Detecting the CYP3AS* 3 genotype of the recipient before the transplantation by the Pyrosequencing TM assays can be used to help determine the optimal initial dosage after transplantation, resulting in individualized drug therapy.
