Figure Lengend Snippet: Effect of IFIT3 on cell malignancy and canonical WNT signaling. A and B , Western blot analysis. GAPDH was an internal control. Quantitative analysis of band intensities is provided in . p-GSK-3β (Ser9), the serine nine phosphorylation of GSK-3β. C–H , quantitative real-time PCR analysis. β-actin was an internal control. Vec, vector, the control group of the IFIT3 expression plasmid. IF3, transfection of IFIT3 expression plasmid. si-IF3, siRNA-IFIT3. si-NC, siRNA-negative control, a scrambled siRNA selected as a negative control. si-IF3 (IF3), following IFIT3 knockdown with siRNA, its expression was restored by transfection with IFIT3 expression plasmid. I–K , dual-luciferase assay. IFIT3 expression plasmid or IFIT3 siRNA was transfected to LUSC/LCLC cells, with or without the treatment of recombinant WNT3A protein. (i) Negative Control: transfection of empty plasmid vector or siRNA-negative control. (ii) Positive Control: treatment of recombinant WNT3A protein. (iii) Test Group 1: transfection of IFIT3 expression plasmid or IFIT3 siRNA. (iv) Test Group 2: transfection of IFIT3 expression plasmid or IFIT3 siRNA, with the treatment of recombinant WNT3A protein. rhW3A, the cells were treated with recombinant human WNT3A protein (100 ng/ml) for 12 h. Error bars indicated mean ± SEM (n = 3). Data were analyzed by two-tailed unpaired Student’s t test for ( C , D , F and G ), and one-way ANOVA with Tukey’s post hoc test for ( E , H–K ). ∗ p < 0.05, ∗∗ p < 0.01, ∗∗∗∗ p < 0.0001. LCLC, large-cell lung carcinoma; LUSC, lung squamous cell carcinoma.

Article Snippet: For analysis of WNT3A response, cells were treated with recombinant human WNT3A protein (100 ng/ml, R&D systems, Cat# 5036-WN-500/CF) for 12 h prior to dual-luciferase assay or Western blot analysis.

Article Title: ROME, an Ancient Gene with a Novel Function in Vertebrates, Is a Key Modulator of Embryonal Development and Cancer Metastasis

doi: 10.1158/2767-9764.CRC-26-0068

Figure Lengend Snippet: ROME protein negatively regulates the Wnt pathway and calcium signaling in human cancer cells. A and B, Compared with EV control cells, TC-71 ( A ) and TC-32 ( B ) cells stably overexpressing ROME were less responsive to recombinant human Wnt3a protein as measured by TOPFlash β-catenin–responsive luciferase reporter. C, TC-71 cells with ROME knockdown by siRNA were more responsive to Wnt3a. D, Endogenous Wnt pathway activity in the colorectal cancer cell line HCT116 was significantly decreased by ROME expression (Western blots confirming ROME-HA expression on the right). Statistical significance was calculated by an unpaired t test (two-tailed) for A–D . E, ROME co-immunoprecipitates with β-catenin in β-catenin pulldown experiments. F, β-Catenin co-immunoprecipitates with ROME in ROME pulldown experiments. G, SPR sensorgrams showing direct binding between the recombinant full-length ROME protein and β-catenin protein. β-Catenin was immobilized on the surface and full-length ROME protein was injected in duplicate at concentrations of 1,250, 416.7, 138.9, 46.3, 15.4, and 5.12 nmol/L. The red lines are the actual data, and the black lines indicate the curve fit. H, ROME expression decreases β-catenin and TCF4 interaction (measured by co-IP). I–K, The Ca 2+ response was decreased in A4573, STA-ET-7.2, and TC-71 cells overexpressing ROME compared with that in EV-transfected cells when the cells were stimulated with ATP or FBS after overnight serum starvation. L, The Ca 2+ response was greater in the TC-71 cells with ROME KO than in the WT cells. Statistical significance was calculated by an unpaired t test (two-tailed) for I–L .

Article Snippet: On the next day, cells were stimulated with recombinant Wnt3a (R&D Systems, #645-WN-010/CF) for 4.5 hours, and then luciferase assay was conducted with the Dual Luciferase Reporter Assay System Kit (Promega, #E1960) according to the manufacturer’s protocol.
