In the A549 cells group, tumors formed in each nude mouse on selleck the 10th day after the s.c. injection (Figure 4B). Tissues collected from the inoculation site were identified as inflammatory necrosis of the Eahy926 cells group, while in such tissues collected from the A549 cells group, masses of classic tumor microstructure were found (Figure 4C and 4D). Moreover, tumor invasion and metastasis to organs such as the liver and the lungs were not found by histological examination in both groups. Figure 4 Tumorigenicity of Eahy926 and A549 cells in vivo. (A) No tumor mass formed roughly within 14 days after s.c. injection of Eahy926 cells; (B) Tumor mass

formed roughly within 10 days after s.c. injection of A549 cells; (C) On day 14 after s.c inoculation of Eahy926 cells; tissues collected from the inoculative site were identified as inflammatory necrosis in the Eahy926 cells

group; (D) On day 14 after s.c inoculation of A549 cells, classic tumor microstructure was www.selleckchem.com/products/obeticholic-acid.html found in the A549 cells group and the rate of tumorigenicity was 100%. Comparative proteomics analysis Two-dimensional electrophoresis based proteomics approach was performed to determine the differently expressed proteins. The images of 2-D gel of both Eahy926 cells and A549 cells were shown in Figure 5 and 6. Twenty-eight proteins, involved in cell proliferation, differentiation, signal transduction and so on, were identified by peptide mass fingerprinting (PMF) and tandem mass spectrometry (TMS) (Table 1). The PMF and TMS maps of Annexin A2 were presented in Figure 7. Of the 28 proteins identified above, 15 were found overexpressed in Eahy926 cells, while 13 were overexpressed in A549 cells.
