Article Title: Aberrant Nuclear Export of circNCOR1 Underlies SMAD7-Mediated Lymph Node Metastasis of Bladder Cancer
doi: 10.1158/0008-5472.CAN-21-4349
Figure Lengend Snippet: circNCOR1 inhibits LN metastasis of bladder cancer by inhibiting the TGFβ–SMAD signaling pathway. A – C, Representative images ( A ) and quantification of the tube formation ( B ) and Transwell migration ( C ) by HLECs cocultured with UM-UC-3 cells. Scale bars, 100 μm. D, The popliteal LN metastatic rate in the nude mice ( n = 12 per group). E and F, Bioluminescence ( E ) and LN volume ( F ) of popliteal LN metastasis in the nude mice ( n = 12 per group). G, Luciferase activity of the SMAD7 promoter in indicated UM-UC-3 cells. H, qRT-PCR analysis of SMAD7 expression in indicated UM-UC-3 cells. I and J, Western blotting of SMAD7 expression in indicated UM-UC-3 ( I ) and T24 ( J ) cells. The statistical difference was assessed by the two-tailed Student t test in B , C , E , and F , and the χ 2 test in D ; and one-way ANOVA followed by Dunnett tests in G and H . Error bars show the SD from three independent experiments. **, P < 0.01.
Article Snippet: The human urinary bladder transitional cell carcinoma cell lines T24 (RRID: CVCL_0554), UM-UC-3 (RRID: CVCL_1783) were purchased from ATCC, RT112 (RRID: CVCL_1670) was purchased from German Collection of Microorganisms and Cell Cultures GmbH (DSMZ) and UM-UC-1 (RRID: CVCL_2743) was purchased from European Collection of Authenticated Cell Cultures (ECACC).
