Beta-catenin
Beta-catenin is a multifunctional intracellular protein encoded by the CTNNB1 gene.
Beta-catenin is a multifunctional intracellular protein encoded by the CTNNB1 gene. It has two major biological roles. At the plasma membrane, beta-catenin links classical cadherins to the actin cytoskeleton and contributes to cell–cell adhesion. In the Wnt/beta-catenin pathway, it also functions as a transcriptional co-activator: Wnt pathway activation stabilizes cytoplasmic beta-catenin, allowing it to accumulate in the nucleus and regulate gene expression with T-cell factor/lymphoid enhancer factor transcription factors.
In the absence of an activating Wnt signal, beta-catenin is targeted for phosphorylation and degradation by a destruction complex that includes components such as AXIN, APC, and glycogen synthase kinase 3. Disruption of this regulatory system can cause persistent beta-catenin Signaling and is associated with abnormal cell proliferation, tissue remodeling, epithelial–mesenchymal transition (EMT), and malignant progression. Altered beta-catenin activity is particularly relevant to Cancers, including colorectal Cancer, and may interact with other Signaling systems such as Yes-associated protein 1 (YAP1) 1 (YAP1), mechanistic target of rapamycin (Mechanistic target of rapamycin (mTOR)), CD44-associated pathways, and signal-transducer and activator of transcription Signaling. Because beta-catenin participates in both adhesion and transcriptional regulation, its cellular distribution and expression are often assessed in tumor biology and targeted Cancer therapy research.

Where the papers sit
10 papers study beta-catenin directly. The themes below are drawn from those 10.
-
Cancer Progression Signaling : Cancer progression is linked to IL-22/IL-22BP imbalance, cell-adhesion changes and YAP1/β-catenin signaling. Reports span colorectal, small-cell lung and osteosarcoma, using recurrence-free survival and metastatic potential as key endpoints. 3 papers · 30%
-
Wnt Signaling in Disease : Nuclear β-catenin and related Wnt signaling recur in fibromatosis, CTNNB1–DLK1 variation in type 2 diabetes and CKD-associated vascular calcification. The common thread is osteogenic transdifferentiation and disease biology, not a unified treatment direction. 3 papers · 30%
-
Others — Molecular Target Discovery : Network pharmacology, molecular docking and multi-omics recur in candidate-target studies, including acute liver injury and nutraceutical mechanisms. An unrelated nail-bed pathology report prevents a shared disease or mechanism from emerging. 4 papers · 40%
Recent Findings on beta-catenin
A 2026 study investigated a BODIPY-based nanotheranostic for osteosarcoma that combined photodynamic and photothermal actions. The work examined beta-catenin in the context of the YAP1/beta-catenin axis, linking this Signaling relationship to malignant progression and the EMT program. The reported mechanistic analyses indicated that the synergistic phototherapy suppressed the YAP1/beta-catenin axis, reversed EMT, and consequently inhibited osteosarcoma cell proliferation, migration, and invasion 42314525Jun. The study therefore positioned beta-catenin as part of a Signaling target combination affected by photochemotherapy, with reactive oxygen species and photothermal effects included in the broader therapeutic mechanism.
A study of advanced colorectal Cancer analyzed the IL-22/IL-22BP axis together with cell-adhesion molecules. Beta-catenin protein expression was evaluated alongside IL-22, IL-22BP, and claudin-1 (CLDN1) by immunohistochemistry on tissue microarrays 42527091Jul. In this setting, beta-catenin was examined as a marker related to cell adhesion and tumor-associated Signaling, rather than as an isolated pathway component. The investigation places beta-catenin within a broader colorectal-Cancer context involving epithelial junctional proteins, cytokine Signaling, and the Wnt/beta-catenin pathway 42527091Jul.
