The results showed that there were expressions selleck chemicals llc of FBG2 gene in MKN-FBG2 cell line and Selleckchem PF2341066 HFE-FBG2 cell line. Figure 4 The immunohistochemistry results of FBG2 in MKN-PC, MKN-FBG2, HFE-PC and HFE-FBG2 cell lines. A: There was no positive signal in MKN-PC cell. B: There was positive signal in MKN-FBG2 cell. The brown positive signals were mainly distributed in cytoplasm. C: There was no brown positive signal in HFE-PC cell too. D: There was positive signal in HFE-FBG2 cell and the brown positive signals were mainly distributed in cytoplasm and cell membrane. The results showed

that there were expressions of FBG2 gene in MKN-FBG2 and HFE-FBG2 cell lines. (×200) Figure 5 The results of Western blot for FBG2 in MKN-FBG2, MKN-PC,

HFE-PC and HFE-FBG2 cell lines. A: m1, m2 were the results of Western blot for FBG2 and β-actin in MKN-FBG2 cells with stable transfection of FBG2 and mp were those in MKN-PC cells, and m0 was those in MKN45 cells. B: h1, h2 were the results of Western blot for FBG2 and β-actin in HFE-FBG2 cells and hp were those in HFE-PC cells, and h0 was those in HFE145 cells. The results showed that there were expressions CX-4945 cost of FBG2 gene in MKN-FBG2 line and HFE-FBG2 cell line, but no expression in other cell lines. The influence of FBG2 gene on the growth of cells The results of cell growth curve assay showed that MKN-FBG2 and HFE-FBG2 cells grew significantly faster than untreated MKN45 and HFE145 cells

or MKN-PC and HFE-PC cells respectively (P < 0.05), and there was no significant difference between the control groups (Figure 6). At 4, 5, 6 and 7 days after inoculation, the average cell counts of MKN-FBG2 group were 2.49 × 105, 3.72 × 105, 4.36 × 105 and 5.01 × 105 respectively, which were significantly more than those of the two control groups (P < 0.05). The average cell counts Progesterone at the same days of HFE-FBG2 group were 2.33 × 105, 3.21 × 105, 3.82 × 105 and 4.63 × 105 respectively, which were significantly more than those of the two control groups too (P < 0.05). Figure 6 The growth curves of MKN-FBG2, MKN-PC, MKN45, HFE-FBG2, HFE-PC and HFE145 cell lines. A: The growth curves of MKN-FBG2, MKN-PC and MKN45 cell lines. The unit of vertical axis was × 105 that of horizontal axis was the number of days. The results showed that MKN-FBG2 cells grew faster than its control groups. B: The growth curves of HFE-FBG2, HEF-PC and HFE145 cell lines. The results showed that HFE-FBG2 cells grew faster than its control groups too. Analysis of cell cycle by using flow cytometry The results of flow cytometry analysis showed that the proportions of the cells in G2-M phase in the MKN-FBG2 and HFE-FBG2 groups were significantly higher than those of the control groups (P < 0.05), the proportions of MKN-FBG2 and HFE-FBG2 cells in S phase were significantly lower than those of the control groups (P < 0.
