OBJECTIVE: To explore the mechanism by which KIAA1456 acts on alveolar epithelial cells through lentiviral transfection.
MATERIALS AND METHODS: After constructing a KIAA1456 gene vector, 293T cells were co-transfected with lentiviral vectors and after incubation cells were examined by fluorescence microscopy. CCL-149 cells were transfected with LV-KIAA1456 and were examined by fluorescence microscopy. The proliferation capacity of transfected CCL-149 cells was evaluated using flow cytometry. The effect of KIAA1456 overexpression on CCL-149 cells proliferation was studied using the CCK-8 method.
RESULTS: The expression level of KIAA1456 in the LV- KIAA1456 group was significantly higher compared with the LV-Con group and the blank group. Compared with the LV-Con and the blank groups, the proportion of responding cells in G2/M phase showed statistically significant differences. Viable cells had adarker color and higher OD value measured by ELISA. Compared with the control and the blank groups, the growth and proliferation in the CCL-149 transfection group were significantly slower.
CONCLUSIONS: KIAA1456 gene inhibited the proliferation of CCL-149 cells by negative regulation of the G2/M cell cycle. We suggest that it can be used as a specific target for the treatment of alveolar epithelium.Free PDF Download
