Figure Lengend Snippet: FIGURE 5 Involvement of miR-1247-3p in the Gallic acid (GA)-inhibited integrin/FAK cascade in DLD-1 cells. Cells were treated with 90 μM GA for 24 h, lysed for total RNA extraction, and subjected to (A) miRNA expression profiling assay via microarray analysis or (B) quantitative analysis of the miRNAs via qPCR. miRNAs with up- and downregulation in response to GA were labeled with red and green, respectively. (C) Cells were transfected with control vector (Ctl-miR) or anti-miR-1247-3p (anti-miR), treated with GA for 24 h, and subjected to the assessment of integrins, FAK, and paxillin by Western blot. Densitometric analysis was performed for semi-quantitation of signals. The tubulin signal was used as internal control. Average signal ratios of phosphorylated protein/total protein compared with the control were indicated.

Article Snippet: Antibodies specifically recognizing human tubulin (SC-134237), integrin αV (SC-376156), integrin β3(SC-365679), focal adhesion kinase (FAK, SC-271126), phosphorylated FAK (pY397-FAK, SC-81493), paxillin (SC-136297), phosphorylated paxillin (pY118-Paxillin, SC-365020), Src (SC-32789), phosphorylated Src (pY416-Src, SC-24621, and CS#2101), and peroxidase-conjugated antibodies against mouse IgG or rabbit IgG were obtained from Santa Cruz Biotechnology, Inc. (CA, USA).

Figure Lengend Snippet: FIGURE 4 Gallic acid (GA) reduced integrin expression and inhibited FAK/Paxillin/Src and PI3K/AKT signaling in DLD-1 cells. Cells were treated with GA at the indicated concentrations for 24 h; collected; and lysed for the immunodetection of (A) integrins and the associated signaling proteins, (B) phosphor-paxillin and Src, and (C) PI3K, phosphor-AKT, and AKT via Western blot. Semi-quantitation of signals was conducted by densitometric analysis. DMSO treatment was used as control (C). Densitometric analysis was performed for the semi-quantitation of signals. The tubulin signal was used as internal control. Average signal ratios of phosphorylated protein/total protein compared with the control were indicated.

Figure Lengend Snippet: Figure 6. AEG-1 activates Wnt/β-catenin signaling via targeting GSK-3β in glioma cells. (A) Enriched top 10 KEGG pathways for Affymetrix microarray of AEG-1 NC (N = 3) and KD (N = 3) glioma cells. 22 DEGs were enriched in KEGG_WNT_SIGNALING PATHWAY. P-value = 1.02E−06. [drawn by R 3.6.0 (https://cran.r- project.org/doc/FAQ/R-FAQ.html#Citing-R)]. (B) Enrichment plot of the Wnt signaling pathway from GSEA; ‘h’ and ‘l’ represented AEG-1 high and low expression, respectively. NES = 1.523, NOM P-value = 0.008, FDR q-value = 0.216 [drawn by GSEA tool (version 4.1.0)]. (C) Western blot bands of AEG-1, β-catenin, GSK-3β, cyclin D1, and CD44 in NC and shAEG-1 glioma cell lines. (D) Relative protein abundance was calculated by ImageJ and GraphPad Prism 8.2.1 software. (E, F) In U251 and U87 cells, Co-IP assays showed the direct interaction of AEG-1 and GSK-3β. (G) Immunofluorescence assays were used to detect the localization of AEG-1 (red) and GSK-3β (green) in U251 and U87 cells. All data were presented as the mean ± SD from three independent experiments. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001.
