Résumé
Objective To investigate the biological function of IFN-λ in 7 human esophageal carcinoma cells. MethodsThe gene expression of IL-28α, IL-10β and antiviral molecule was examined with PCR. The MHC molecules expression and the profiles of cell cycle were analyzed with flow cytometer. Cell proliferation was evaluated with MTT assay. ResultsAll of esophageal carcinoma cells express the gene of II-28α and IL-10β. IFN-λ induced or augmented the gene expression of antiviral molecules, 2′5′-OAS and MxA. IFN-λ enhanced the MHC class Ⅰ molecule expression. IFN-λ inhibited the growth of esophageal carcinoma cells through the regulation of cell cycle distribution. ConclusionEsophageal carcinoma cells express the IFN-λ receptor complex. IFN-λ has the antiviral, anti-proliferative and immunoregulation activity.
Résumé
The valuators affect the results of performance evaluation directly.By construing the objective requirements of performance evaluation,the motivation of stakeholders,and the diversity of evaluating objects,we then set forth the necessity of valuator's multipluralism in the performance evaluation of comprehensive prevention and treatment of HIV/AIDS.We also put forward another pertinent advice that multiplural valuators should take part in general HIV/AIDS prevention and treatment evaluation,thus providing a reference for guaranteeing the results of performance evaluation,and the advancement and improvement in the performance of HIV/AIDS comprehensive prevention and treatment.
