Figure Lengend Snippet: Determination of the molecular mechanism of WISP1v1 on the cell invasion in the bladder cancer cells. (A) The protein levels of NDRG1, KAI1, and Maspin of HT-DNA and HT-WISP1v1 cells were determined by immunoblot assays. (B) The luciferase activity of the NDRG1 reporter vector was shown after transiently overexpressing various amounts of WISP1v1 expression vectors in HT1376 and T24 cells, as indicated. (C) The luciferase activity of KAI1 and Maspin reporter vectors was shown as indicated after transiently overexpressing various dosages of WISP1v1 expression vectors in HT1376 cells. (D) The luciferase activity of NDRG1, KAI1, and Maspin reporter vectors, respectively, after transiently overexpressed pcDNA, WISP1v1, and WISP1v2 expression vectors as indicated in HT1376 cells. (E) The mRNA levels of the E-cadherin, N-cadherin, Slug, Snail, and Vimentin were determined by RT-qPCR. Data are presented as target genes/β-actin of HT-WISP1v1 cells relative to HT-DNA cells. The mRNA levels of the WISP1 (F), NDRG1, KAI1, Maspin, and IL-6 (G) after transient overexpression of WISP1v1 in T24 cells were determined by RT-qPCR. Data are presented as target genes/β-actin of T24-WISP1v1 cells relative to T24-DNA cells. (H) The invasion ability of T24 cells after the ectopic overexpression of WISP1v1 was determined by in vitro Matrigel invasion assays (± SE; n = 4). The ability of the migration (I) and quantification analysis (I) of T24 cells after being treated with the supernatant from 293T-DNA and 293T-WISP1v1 cells was determined by wound healing assays. The white line indicated the average of the leading cellular edges, and the wound area size was calculated by Image J. * p < 0.05, ** p < 0.01.
