Figure Lengend Snippet: SP and CGRP neutralization reverses DRG-induced EMT and FMT in 11Z cells. ( A ) Representative morphology of 11Z cells treated with medium, the DRG supernatant with pre-treatment with aprepitant (10 −6 M), CGRP fragment 8–37 (10 −6 M), or both aprepitant (10 −6 M) and CGRP 8–37 (10 −6 M), or without for 12 days. Scale bar = 100 μm. ( B ) Left panel: Detection of protein levels of E-cadherin by immunoblotting of lysates of 11Z cells treated with indicated condition for 12 days (n = 3). The grouping of blots from the same protein were not cropped, and all protein blots were from the same gel. Right panel: Relative fold change in protein levels of E-cadherin in 11Z cells treated with indicated condition for 12 days (n = 3). ( C ) Relative fold change of gene expression levels of Snai1, Slug, vimentin, N-cadherin, and PAI-1 in 11Z cells treated with indicated conditions for 12 days (n = 3). Values are normalized to the GAPDH expression levels. ( D ) Results of SP and CGRP neutralization on cellular proliferation of 11Z cells, as measured by CCK-8 assay (n = 8). The 11Z cells were treated with the indicated conditions for 12 days. ( E ) Results of SP and CGRP neutralization on cell migratory capacity, as evaluated by the scratch assay, of 11Z cells treated with indicated conditions for 12 days. The cells were photographed at 0, 12, 24 and 48 hours, respectively, after being scratched. The distance between two edges that cells traversed was calculated relative to the initial scratch distance as measured with pixel values. Scale bar = 100 μm. ( F ) Results of SP and CGRP neutralization on invasiveness. The representative photomicrographs of the invaded 11Z cells in the transwell assay after indicated treatments (Magnification: × 200). Cells, after 12 days’ indicated treatments, were added to the top of transwells coated with Matrigel and treated as indicated. The total number of cells invaded to the bottom of the transwell was then counted. Scale bar = 100 μm. * or # p < 0.05, ** or ## p < 0.01, *** or ### p < 0.001; N: not statistically significant (p > 0.05). Data are represented in means ± SDs. Symbols of statistical significance: *, **, and *** indicate different significant levels when compared with the untreated cells, while #, ## , and ### indicate different significant levels when compared with the cells treated with the DRG supernatant. * or # p < 0.05; ** or ## p < 0.01; *** or ### p < 0.001.

Article Snippet: For inhibitor experiments, cells were pretreated with vehicle or the potent NK1R antagonist aprepitant (Selleckchem) (10 −6 M) or CGRP Fragment 8–37 (CGRP 8–37) (Sigma) (10 −6 M) , a selective competitive antagonist for CGRP receptors, for 1 hour at 37 °C.
