Abstract
Objective To transfect the recombinant mIL-28A adenovirus vector into lung adenocarcinoma cell line LA795 and research its anticancer activity. Methods Transfected the constructed mouse IL-28(mIL-28) recombinant adenovirus vector into LA795 cell line, detected with PCR, immunocytal fluorescence, Tunel, Annexin V and MTT. Results Transfected with rAd-mlL-28A into the LA795 cells, mIL-28A gene expression products mRNA increased obviously, IL-28 expression was detected in cells obviously,apoptosis cell number increased, and the growth of LA795 cells transfected with rAd-mIL-28A were inhibited obviously. Conclusion The recombinant miL-28A adenovirus vector we have constructed, which expresses IL-28 when transfected to lung adenocarcinoma cell line LA795, inhibits growth of carcinoma cell to some extent, and may work by promoting the apoptosis of cancer cells. Key words: mIL-28; Adenovirus vector; Lung cancer; Growth; Apoptosis
