Figure 2 Restored expression of ECRG4 in glioma U251 cells. A. Real-time PCR analysis indicated the highest mRNA expression of ECRG4 in two cell clones pEGFP-ECRG4-5 and -7. B. Western blotting assay shows significantly increased protein expression of ECRG4 in pEGFP-ECRG4-5 and -7 comparing to Control Talazoparib in vitro cells. β-actin was used as the internal control.

ECRG4 inhibits cell proliferation in vitro To analyze the function of ECRG4, we studied the rate of cell proliferation of ECRG4-expressing ECRG4-5 and -7 cells. The growth curves determined by an MTT assay showed that ECRG4 significantly inhibited cell proliferation of these two lines of cells compared to parental line U251 and Control clone cells (Figure 3A).

Figure 3 Overexpression of ECRG4 inhibted cell proliferation in Selleckchem NVP-BSK805 vitro. A. The cell growth of parental U251 cells, Control-vector cells and pEGFP-ECRG4-5 and -7 cells, were examined by MTT assay over a seven-day period. *P < 0.05, as compared

to U251 and Control-vector cells. B. The cell growth of Control-vector cells and pEGFP-ECRG4-5 and -7 cells, were examined by plate colony formation assay. *P < 0.05, as compared to U251 and Control-vector cells. ECRG4 suppressed cell migration and invasion To measure the effect of ECRG4 on cell migration, ECRG4-expressing ECRG4-5 and -7 cells were cultured on a transwell apparatus. After 12-h incubation, cell migration was significantly decreased in both ECRG4-overexpressed cell groups compared to the parental U251 cells and the ECRG4-negative control cells (for both P < 0.001) (Figure 4A). TCL Using a Boyden chamber coated with matrigel, we measured cell invasion after 16-h incubation.

Compared with the negative control cells, ECRG4-expressing -5 and -7 cells both showed significantly decreased invasiveness (for both P < 0.001) (Fig 4.B). Figure 4 Increased ECRG4 expression inhibited cell migration, invasion and cell cycle progression. (A) Cell migration and (B)invasion capabilities of Control-vector cells, pEGFP-ECRG4-5 and -7 cells, were examined using transwell assay and boyden chamber assay. Data were presented as mean ± SD for three independent experiments. *P < 0.05, as compared to Control-vector cells. C. Cell cycle in parental U251 cells, Control-vector cells and pEGFP-ECRG4-5 and -7 cells, was determined by FACS Caliber cytometry. *P < 0.05, as compared to parental U251 cells and Control-vector cells Inhibition of cell cycle by ECRG4 To detect the effect of ECRG4 on the cell cycle, we measured cell cycle distribution in ECRG4-expressing -5 and -7 cells.
