Article Title: Epigenetic silencing of JAM3 promotes laryngeal squamous cell carcinoma development by inhibiting the Hippo pathway
doi: 10.3892/or.2024.8861
Figure Lengend Snippet: JAM3 mediates laryngeal squamous cell carcinoma tumorigenesis through the Hippo pathway. (A) Protein levels of Flag, JAM3, p-LATS1 (Thr1079), LATS1, p-YAP1 (Ser127), YAP1 and β-actin in AMC-HN-8 and FD-LSC-1 cells with overexpression or knockdown of JAM3 were detected by western blotting. (B) Expression of YAP1 in AMC-HN-8 and FD-LSC-1 cells after transfection with the JAM3 overexpression plasmid or si-JAM3 were detected by confocal microscopy. Scale bar, 50 µm. Fluorescence ratio of YAP1 in the cytoplasm and nucleus of (C) AMC-HN-8 and (D) FD-LSC-1 cells was calculated by ImageJ and analyzed by two-tailed Student's t-test or one-way ANOVA. Data are presented as the mean ± SD of three independent experiments. *P<0.05 vs. Vec; # P<0.05, ## P<0.01, ### P<0.001, #### P<0.0001 vs. si-NC group. JAM3, junctional adhesion molecule 3; LATS1, large tumor suppressor kinase 1; NC, negative control; p-, phosphorylated; si, small interfering; Vec, p3×Flag-CMV-10 empty vector; YAP1, yes-associated protein 1.
