Figure Lengend Snippet: Figure 3. Effect of RasGRP2 overexpression on Rap1 activation and cell adhesion. (A) Rap1 activation assessed by Rap activity assay. Upper panel, active form of Rap1; middle panel, total Rap1. (B) Rap1 activation assessed by Rap activity assay with or without 10 μM BAPTA-AM (BA, intracellular calcium chelator) for 30 min. (C) Cell adhesion assessed by adhesion assay. Data are shown as the mean ± SD (n = 3) *P < 0.05, **P < 0.01 vs. ECV304mock.

Article Snippet: After washing with PBS containing 0.05% Tween 20 (PBS-T), the membranes were incubated with rabbit anti-RasGRP2 antibody (GeneTex), mouse anti-β-actin antibody, rabbit anti-Rap1 antibody (Santa Cruz), mouse antipan-Ras antibody (Cell Biolabs), rabbit anti-phospho-p44/42 MAPK antibody, or rabbit anti-p44/42 MAPK antibody (Cell Signaling) in Can Get Signal® Solution 1 (Toyobo) for 1 h. Subsequently, the membranes were washed thrice with PBS-T and incubated with anti-rabbit IgG antibody (GeneTex) or antimouse IgG antibody (DakoCytomation) in Can Get Signal® Solution 2 (Toyobo) for 1 h. After five additional washes with PBS-T, immunoreactive proteins were detected using ECL Prime Western Blotting Detection Reagents and Amersham hyperfilmTM ECL (GE Healthcare).

Figure Lengend Snippet: Fig. 5. Rap1 overexpression reverses the expression of key proteins in CD147 knockdown mediated cell proliferation, apoptosis and EMT. (A, B) Western blot analysis of Rap1 and Rap1GAP protein levels in HCT116 and SW620 cells after CD147 knockdown (shCD147). β-actin served as a loading control. Data represent mean ± SD (n = 3; **P < 0.01, ***P < 0.001 vs. shNC, Student’s t-test). Original blots are presented in Supplementary Fig. 3. (C) qRT-PCR validation of Rap1 mRNA overexpression in CD147-knockdown cells. Expression normalized to β-actin (n = 3; ***P < 0.001 vs. HCT116 or SW620, Student’s t-test). (D, E) Western blot analysis of c-Myc, Bcl-2, Bax, N-cadherin, and E-cadherin protein levels in CD147-Knockdown cells with Rap1 overexpression (n = 3; *P < 0.05, **P < 0.01, ***P < 0.001 vs. shNC, #P < 0.05, ##P < 0.01, ###P < 0.001 vs. shCD147, one-way ANOVA). Original blots are presented in Supplementary Fig. 4.
