Summary: PRMT7 plays an important role in cardiac hypertrophy and fibrosis. Overexpression of PRMT7 can alleviate cellular hypertrophic response, while depletion of PRMT7 exacerbates hypertrophic response. Transcriptome analysis reveals altered gene expression profile related to Wnt signaling pathway in PRMT7-deficient hearts.

Summary: Reception of Wnt signals is mediated by Frizzled receptors and a co-receptor LRP6 or LRP5. Precise control of receptor activation is crucial to regulate Wnt/beta-catenin signaling for proper cellular function. A glycosyltransferase B3GnT2-like has been identified to modify LRP6 and enhance Wnt/beta-catenin signaling. This study highlights the importance of LRP6 as a regulatory hub in Wnt signaling and provides insight into the selective targeting of a signaling pathway component by a specific glycosyltransferase.

Summary: Notch and Wnt are two essential signaling pathways in animals, with typically opposing effects on cell fate decisions. Notch can limit Wnt signaling through mechanisms at the cell membrane and in the cell nucleus, contributing to the robustness of cell fate decisions by sharpening the distinction between opposing Notch/Wnt responses.

Summary: The study revealed that BCL9L and Wnt/beta-catenin signaling play an oncogenic role in bladder cancer cells, and may be associated with the progression of bladder cancer. Mutations in UTRs of BCL9L can affect its activity, thereby influencing cell proliferation, migration, and invasion.

Summary: The study revealed that circ_0119872 is upregulated in UM cell lines and tissues, promoting the malignancy of UM cells. Additionally, circ_0119872 can directly interact with miR-622, acting as a miRNA sponge to regulate the expression of the miR-622 target gene G3BP1 and downstream Wnt/beta-catenin and mTOR signaling pathways.

Summary: This study found that the protein level of NET1 is increased in a mouse cardiac fibrosis model, as well as in cardiac fibrosis induced by TGF-beta 1. Overexpression of NET1 promotes beta-catenin expression and increases the proliferation and migration of cardiac fibroblasts. NET1 may interact with beta-catenin through GSK3b. Knockdown of beta-catenin alleviates the effects of NET1 overexpression on collagen production and cell migration. In conclusion, NET1 may regulate the activation of Wnt/beta-catenin and TGF/Smads signaling pathway, promote collagen synthesis in fibroblasts, and participate in cardiac fibrosis.

Summary: Researchers used mathematical models to analyze Wnt signaling in early vertebrate embryogenesis, finding different classes of target genes for the zygotic Wnt signaling. A simplified model was able to largely describe the regulatory behavior observed experimentally, suggesting that one super-gene for each class is sufficient.

Summary: The study showed that the silencing of SERPINB2 can promote osteogenic differentiation of BMSCs through the Wnt/β-catenin signaling pathway. In vivo experiments demonstrated that silencing SERPINB2 effectively improves bone fracture healing, suggesting that SERPINB2 may be a novel target for bone fracture healing.

Summary: Specific signalling thresholds of the WNT/beta-catenin pathway affect embryogenesis and tissue homeostasis. Currently, there is a lack of specific in vivo assays to evaluate inhibitors of WNT/beta-catenin signalling. We present a simple in vivo assay to assess the efficacy and bioavailability of candidate compounds.

Summary: This study provides mechanistic insight into ciliary ubiquitin processing and uncovers UBE2E1 and RNF34 as novel interactants of MKS1. UBE2E1 mediates both regulatory and degradative ubiquitination of MKS1, and phosphorylated beta-catenin processing occurs at the ciliary base.

Summary: This article describes a highly consanguineous family with multiple perinatal deaths and infants presenting at birth with failure to thrive, severe salt-wasting crises associated with isolated hypoaldosteronism, nail anomalies, short stature, and deafness. Whole exome sequencing revealed a homozygous splice variant in the R-SPONDIN receptor LGR4 gene (c.618-1G>C) regulating WNT signaling. The impact of LGR4 inactivation was analyzed by adrenal cortex-specific ablation of Lgr4, which resulted in abnormal zG differentiation and endocrine function.

Summary: Epigallocatechin-3-gallate (EGCG), a unique catechin from tea leaves, has potential anticancer effects in osteosarcoma. Cellular and animal experiments have shown that EGCG promotes apoptosis and inhibits proliferation, migration, and invasion of osteosarcoma cells. EGCG also suppresses tumor cell damage to bone and distant lung metastasis.

Summary: This study highlights the importance of positive charge and PEG chains in the G-quadruplex binding ability and antiproliferative activity of PMIs, with PMI6 showing the most promising potential. The cationic PMI6 with two PEG chains exhibits enhanced fluorescence in the presence of G-quadruplex structures and high affinity towards human telomeric G-quadruplex hTelo, as well as high antiproliferative potential against certain cancer cells.

Summary: We describe an optimized protocol for expansion microscopy (ExM) on chick neural tube (NT) that allows nanoscale resolution imaging of centrosomes/cilia in different orientations. We explain the preparation of transverse sections and open-book preparations of embryo NT, immunohistochemistry for labeling, and sample preparation for 5-fold tissue expansion. Furthermore, we provide details on sample orientation and Fast Airyscan confocal acquisition, and demonstrate that NT-ExM retains fluorescence signals and overcomes biomolecule crowding in structural features that were previously imaged only with electron microscopy.

Summary: In the developing spinal cord, neurogenesis stimulates Tcf-dependent transcription through the nuclear accumulation of beta-catenin, independently of Wnt signaling. This process regulates genes involved in contralateral axon growth, including axon guidance and adhesion. These findings demonstrate the importance of Wnt-independent Tcf/beta-catenin regulation in controlling commissural axon growth in the chick spinal cord.

Summary: Vinculin is an actin-binding protein that plays a crucial role in cell adhesion and cytoskeleton connection. Beta-catenin targets vinculin to the apical adherens junctions and centrosome in the embryonic neural tube. Suppression of vinculin affects neural stem cell division and disrupts the integrity of the cell cytoskeleton.
