Article Title: Role of ROR2 in promoting gastric cancer metastasis by enhancing c-JUN-mediated MMP3 transcription
doi: 10.21037/atm-22-4583
Figure Lengend Snippet: ROR2 promoted gastric cancer cell migration, invasion, and metastasis. (A,C) SNU601 cells stably expressing ROR2 WT and Con as well as SGC7901 cells stably expressing shROR2 and NC were subjected to transwell migration (A) and invasion assays (C). Representative images at 200× magnification and quantitative analysis of transwell assays after crystal violet staining are presented. Columns are the mean of 3 independent experiments, and bars = SD. (B) Wound-healing assay. The red lines indicate the initial scratch wound location, while the yellow blocks show unhealed areas left by migratory cells. Images were captured at the indicated times after wounding. Representative images and quantitative analysis of relative wound density are presented. (D) Three-dimensional culture assay. Representative images at 100× magnification and 200× magnification show the spheres formed by SNU601-ROR2 WT and Con. (E) SNU601 cells stably expressing ROR2 WT and Con were respectively injected into BALB/c nude mice through the tail vein. Representative images at 100× magnification (upper) and 200× magnification (lower) of HE staining of lung sections are shown (left). Quantitative analysis of the number of metastatic tumors in the lungs of nude mice (upper right) and lung weight (lower right). Columns are the mean of 3 independent experiments, and bars = SD. *, P<0.05; **, P<0.01; ***, P<0.001. SD, standard deviation; ROR2 WT and Con, ROR2-overexpressing (WT) and the empty vector plasmids (Con); shROR2 and NC, short hairpin (shRNA) targeting ROR2 (shROR2) and the empty vector plasmids (NC); HE, hematoxylin and eosin.
