Objective To study the expression and significance of ?-catenin in keratosic dermatosis and non-melanocytic skin tumors. Methods ?-catenin expression was determined in 10 specimens of normal skin,10 cases of seborrheic keratosis(SK),26 cases of actinic keratosis(AK),17 cases of Bowen's disease(BD) and 35 cases of primary cutaneous squamous cell carcinoma(SCC) by immunohistochemical EnVision two-step staining method. Results The expression of ?-catenin was significantly higher in SK,AK,BD and SCC than in normal skin(P0.05),but that was significantly lower in SK and AK than in BD(P0.05). Conclusion The cytoplasmic and/or nuclear expression of ?-catenin may play a role in the progression from normal skin to keratosic dermatosis and non-melanocytic skin tumors.

This study aimed to construct full-length cDNA clones of the Japanese encephalitis virus (JEV). SA14-14-2 strain and discuss the feasibility of constructing chimeric viruses for exogenous gene expression based on the JEV genetic skeleton. Long-fragment RT-PCR techniques were applied to amplify JEV cD-NAs, and two amplified fragments with corresponding restriction endonuclease sites at both ends were cloned into the pACYC184 vector sequentially. Using standard molecular techniques, the enhanced green fluorescent protein (EGFP) gene was inserted into the 3' non-coding region of JEV as a reporter gene. After in vitro transcription and transfection procedures, wild-type JEV and chimeric JEV that expressed the EGFP as the reporter gene were successfully rescued. The recovered viruses were characterized by RT-PCR, plaque assays, and direct fluorescence microscopy. After six serial passage generations, the stability of the recovered viruses were studied in terms of virus growth characteristics and structural gene expression. The results showed that cDNA clones of rJEV and rJEV-EGFP were successfully constructed and rescued in BHK-21 cells after in vitro transcription and transfection. Each generation of the recovered viruses was stable and the chimeric virus rJEV-EGFP could stably express EGFP. The findings of this study indicate that both rJEV and rJEV-EGFP could be constructed and rescued in BHK-21 cells, and the JEV SA14-14-2 strain could be obtained as a viral vector to express foreign genes.
