BACKGROUND: It has been widely reported that the most types of cancer are probably originated from cancer stem cells (CSCs) which are subpopulations of tumor cells. Recent studies also suggested that lung cancer could arise from CSCs. However, the phenotypic characteristics of CSCs in lung cancer have not been precisely described.OBJECTIVE: To systematically analyze the expression of the most common CSC markers in cell line A549.METHODS: A549 cells were cultured for 1 week under the condition of conventional high glucose. After that, flow cytometry was used to assess the expression of putative stem cell markers, including CD133, CD24, CD44 and ABCG2.Cells were then sorted according to the expression of CD44 and CD24 markers by fluorescence-activated cell sorting (FACS) and characterized using their sphere-forming capacity in serum free medium supplemented with several growth factors.RESULTS AND CONCLUSION: A549 cells expressed the CSC markers CD44 and CD24 at 64.23% and 58.62%,whereas the expression of both ABCG2 and CD133 was around 0.9%. Double-positive CD44/133 populations were rare.CD44+/CD24+ and CD44+/CD24- subpopulations respectively exhibited 54.64% and 23.38% expression. CD44+/CD24+ and CD44+/CD24- subsets were sorted by FACS. Both isolated subpopulations formed spheres in the serum free medium supplemented with basic fibroblast growth factor and epidermal growth factor. However, there was no significant difference in the sphere formation efficiency among CD44+/CD24+ and CD44+/CD24- subsets as well as A549 cells. Our findings suggest that CD44 and CD24 cannot be considered as potential markers for isolating lung CSCs in cell line A549, and further investigation using in vivo assays is required.

Aim To investigate TH and GDNF genes expression and regulation of lentivirus ( Lv-TH-GDNF ) based on improved Tet-On system and the effect of the Lv-TH-GDNF intrastriatal transfer on a rat Parkinson’ s disease( PD) model. Methods 1. HeLa cells were infected by obtained Lv-TH-GDNF and rtTA2 s-M2 vi-rus. The expression of tyrosine hydroxylase ( TH ) and glial cell line-derived neurotrophic factor( GDNF) genes was induced by doxycycline( Dox) which was examined by Western blot. 2. The Lv-TH-GDNF together with rtTA2 s-M2 viruses were injected into lesion-side stria-tum of a rat PD model, and the expression of GDNF and TH genes was induced by Dox. Then, the effects of Lv-TH-GDNF were evaluated by the apomorphine-induced rotational behavior, the number of dopaminer-gic neurons in substantia nigra,DA and DOPAC levels in the lesion-side striatum. In addition, Western blot was performed to check the expression of TH and GD-NF genes in the transplanted striatum. Results 1. In vitro studies on HeLa cells, Western blot showed clear protein bands of TH and GDNF in the Dox-positive group, but not in the Dox-negative group. 2. In vivo experiments in animals, the results showed that, 4 weeks after transplantation, the apomorphine-induced turning effect was significantly improved ( P<0 . 01 ) , the number of TH-positive cells in the lesion-side sub-stantia nigra pars compacta as well as the content of DA and DOPAC, the protein level of GDNF and TH genes in the lesion-side striatum was significantly in-creased ( P<0 . 01 ) , each of which was only in Lv-TH-GDNF+rtTA2 s-M2+Dox-treated rats as compared with PBS-treated rats. Conclusion The expression of TH and GDNF genes in Lv-TH-GDNF based on im-proved Tet-On system is effectively regulated by tetra-cycline antibiotics without basal activity in vitro, and the intrastriatal transfer of which has certain therapeutic effect on PD rats.
