Article Title: Wnt/β-catenin signaling promotes zebrafish osteoblast dedifferentiation by wnt10a -mediated inhibition of NF-κB

doi: 10.64898/2025.12.29.696582

Figure Lengend Snippet: A) RNASeq (left) and RT-qPCR (right) reveal upregulation of the NF-κB signaling target genes nfkbiaa and nfkbiab in osteoblasts sorted from bglap:GFP fish heterozygous for the wnt10a mutation relative to their wild-type siblings at 1 dpa. nE (qPCR biological replicates) = 3, nA = 10 per replicate. ΔΔCt values are normalized to the mean of the wildtype at 1 dpa. Error bars, Mean ± SEM. Two tailed Student’s t-test. B) Osteoblast dedifferentiation, as measured by bglap downregulation in segment -1 revealed by HCR in situ hybridization, is inhibited in fish treated with the Wnt inhibitor IWR-1, while IP injection of the NF-κB inhibitor Bay-11 slightly but significantly enhances dedifferentiation. Treatment with both inhibitors yields results similar to those of Bay-11 alone. nE = 3 (except for 2 for IWR-1), nA = 18 total per group (12 for IWR-1), nR = 33 (DMSO), 24 (IWR-1), 37 (Bay-11), 33 (both). C) Overexpression of wnt10a using hs:wnt10a fish is sufficient to cause downregulation of bglapl detected by HCR in situ hybridization in non-injured fins, relative to heat-shocked wild-type fish. HCR signals were quantified in a bony segment (“B”) that is located at the same proximal-distal position as “segment -1” in amputated fins. nE = 2, nA = 12 total per group, nR = 22 total per group. Dashed line, joints. Scale bar, 100 µm. D) Immunofluorescence on cryosections of hs:wnt10a transgenic hearts reveals increased embryonic myosin heavy chain (embMHC) expression in Myl7+ cardiomyocytes at the wound border at 7 days post injury (dpi). Plots show the ventricular area covered by anti-embMHC staining relative to the 150 µm wound border zone area occupied by Myl7+ myocardium. nE = 2, nA = 13 wild-type, 11 hs:wnt10a . Scale bar, 100 µm. (B, C, D) Error bars, mean ± 95% CI. Two tailed Student’s t-test.
