Article Title: Syndecan-2 positively regulates Wnt/β-catenin signaling in breast cancer cells.
Article Snippet: Syndecans are a family of four-member transmembrane heparan sulfate proteoglycans that bind to various extracellular biomolecules, such as Wnt ligands, via their heparan sulfate chains, thereby controlling a variety of cellular processes.. When dysregulated, syndecans can affect tumorigenesis and cancer progression by modulating key signaling pathways involved in the regulation of biological functions.. Aberrant activation of Wnt/β-catenin signaling is a hallmark of many human tumors, including breast cancer.

A) Mesenchymal cells harvested from the frontonasal mass of stage 24 (E4.5) embryos and were plated into high-density cultures. B) Other cultures were sectioned and used for microscopic analysis. C,E-H) There is a significant decrease in the proportion of cartilage from the DVL1 1519ΔT variant compared to the wtDVL1 infected cultures as measured in wholemount stained cultures. When the DVL1 1519* truncation was compared to wtDVL1 there was no significant difference in the Alcian blue stained area. The DVL1 1519* construct reduced cartilage compared to GFP controls. D,I-L) The cultures were significantly thinner in the presence of the DVL1 1519ΔT variant compared to w tDVL1 or the GFP controls. The DVL1 1519 * construct slightly reduced the thickness of the cartilage compared to GFP controls. M) The viruses containing human DVL1 constructs were expressed at similar levels in primary mesenchyme as determined by qRT-PCR with human-specific DVL1 primers. Generally the human DVL1 gene expression was elevated 10 to 15-fold by the viral transgenesis. N, O) The 1519ΔT virus significantly reduced expression of TWIST2 , MMP13 and LEF1 . P,Q) Two reporters were used in micromass cultures from frontonasal mass cells, the <t>SuperTOPFlash</t> reporter for canonical WNT signaling and ATF2 for JNK-PCP, non-canonical WNT signaling. The wt DVL1 plasmid significantly activated both reporters. In comparison both 1519ΔT and 1519* viruses did not activate the reporters as much as wt DVL1 . They did retain more activity than the control, parent plasmid. Statistical analysis done with one-way ANOVA followed by Dunnett’s multiple comparison test ( M ) or Tukey’s post-hoc test (C,D,N,O,P,Q). Scale bar in E-H = 2 mm, I-L = 20µm.

Data are represented as the mean ± SD of three independent experiments, each performed in triplicate. * p < 0.05, ** p < 0.01, *** p < 0.005, ns not significant as determined by analysis of variance (ANOVA).

Article Snippet: HEK293T cells were transfected with M50 Super 8x TOPFlash (Addgene #12456) or the FOP control plasmid (M51 Super 8x FOPFlash Addgene #12457) in combination with TK Renilla (Promega #E2241) using DreamFect Gold (OZ Biosciences #DG80500) according to the manufacturer's instructions.

A) Mesenchymal cells harvested from the frontonasal mass of stage 24 (E4.5) embryos and were plated into high-density cultures. B) Other cultures were sectioned and used for microscopic analysis. C,E-H) There is a significant decrease in the proportion of cartilage from the DVL1 1519ΔT variant compared to the wtDVL1 infected cultures as measured in wholemount stained cultures. When the DVL1 1519* truncation was compared to wtDVL1 there was no significant difference in the Alcian blue stained area. The DVL1 1519* construct reduced cartilage compared to GFP controls. D,I-L) The cultures were significantly thinner in the presence of the DVL1 1519ΔT variant compared to w tDVL1 or the GFP controls. The DVL1 1519 * construct slightly reduced the thickness of the cartilage compared to GFP controls. M) The viruses containing human DVL1 constructs were expressed at similar levels in primary mesenchyme as determined by qRT-PCR with human-specific DVL1 primers. Generally the human DVL1 gene expression was elevated 10 to 15-fold by the viral transgenesis. N, O) The 1519ΔT virus significantly reduced expression of TWIST2 , MMP13 and LEF1 . P,Q) Two reporters were used in micromass cultures from frontonasal mass cells, the SuperTOPFlash reporter for canonical WNT signaling and ATF2 for JNK-PCP, non-canonical WNT signaling. The wt DVL1 plasmid significantly activated both reporters. In comparison both 1519ΔT and 1519* viruses did not activate the reporters as much as wt DVL1 . They did retain more activity than the control, parent plasmid. Statistical analysis done with one-way ANOVA followed by Dunnett’s multiple comparison test ( M ) or Tukey’s post-hoc test (C,D,N,O,P,Q). Scale bar in E-H = 2 mm, I-L = 20µm.
