Wint™

• Targets the Wnt signaling pathway

  DKK-1 blocks excessive activation of Wnt signaling, limiting downstream cellular mechanisms associated with osteoarthritis and reducing Wnt/β-catenin pathway activity.44

• Supports cartilage protection

  By inhibiting excessive Wnt signaling and OA-related gene expression, the Wint™-derived product may help protect joint cells and limit degenerative processes affecting articular cartilage.1

• Supports joint function and symptom relief

  Clinical observations indicate pain reduction and functional improvement following treatment, including improvements in stiffness and physical function.45

The role of Wnt signaling in OA pathology and progression

The Wnt signaling pathway plays a pivotal role in multiple biological processes, including the development and homeostasis of articular joints and cartilage.46 Dysregulation of Wnt signaling has also been associated with the development and progression of osteoarthritis (OA).44

In the canonical Wnt/β-catenin pathway, Wnt ligands bind to cell-surface receptors, leading to inhibition of the β-catenin destruction complex. As a result, β-catenin accumulates in the cytoplasm and subsequently translocates to the nucleus, where it interacts with TCF/LEF transcription factors to regulate the expression of target genes. Dysregulated activation of this pathway in joint tissues, including chondrocytes and synovial cells, has been associated with osteoarthritis-related changes and disease progression.44

Evidence supporting the relevance of DKK-1-mediated Wnt signaling modulation in OA:

• Reduced circulating DKK-1 levels have been observed in patients with knee OA.47

• Plasma DKK-1 levels have been shown to inversely correlate with radiographic severity of knee OA.47

• Experimental studies demonstrate that increased DKK-1 expression in chondrocytes can inhibit Wnt-mediated cartilage degradation and reduce OA progression.48
