Cross-talk between MEGF11 and IL-17A. MEGF11 was knocked down with short hairpin RNA (shRNA) and over-expressed with the pCMV-AC-GFP vector in TNBC cell line MDA-MB-231 and MDA-MB-468 cells. When the MEGF11 gene was knocked down, mRNA transcripts of IL-17A in ΔMEGF11 (a) and o/e MEGF11 (b) were quantified by real-time PCR (n = 4). After administration of different doses (0, 0.001, 0.1 ng/mL) of IL-17A in cultured media, MEGF11 protein (c) and IL-17A-related signalling proteins in MDA-MB-231 (d) and MDA-MB-468 (e) were analysed by Western blot (n = 4–6). The mRNA transcripts of MEGF11, IL-17A, and IL-17 receptors (IL17RB, IL17RC) in MDA-MB-231 and MDA-MB-468 cells (f) were quantified with real-time PCR (n = 6). Data between two groups were analysed with Mann-Whitney U or Student’s t test, while dose-related data were analysed with one-way ANOVA, followed by Dunnett’s post hoc test. Asterisks indicate a p value <0.05 compared to the wild type (for ΔMEGF11), the scramble group (for o/e MEGF11) or the vehicle group (for dose-dependent study).
