背景信息

**Background of WISP1 Recombinant Protein**

WISP1 (WNT1-inducible signaling pathway protein 1), also known as CCN4. belongs to the CCN family of matricellular proteins, which regulate cell proliferation, differentiation, adhesion, and extracellular matrix (ECM) remodeling. It is encoded by the *WISP1* gene and is transcriptionally activated by the Wnt/β-catenin signaling pathway. WISP1 plays critical roles in tissue repair, embryonic development, and pathological processes such as fibrosis, cancer progression, and metabolic disorders.

Structurally, WISP1 contains four conserved domains: an insulin-like growth factor-binding domain (IGFBP), a von Willebrand factor type C module (VWC), a thrombospondin type 1 repeat (TSP1), and a C-terminal cysteine-knot domain (CT), enabling interactions with cell surface receptors (e.g., integrins) and ECM components. Recombinant WISP1 protein is produced using expression systems (e.g., *E. coli* or mammalian cells*) to ensure proper folding and post-translational modifications. It is widely used in research to study its biological functions, including its dual role in promoting cell survival or apoptosis, depending on cellular context.

In disease, WISP1 is overexpressed in cancers (e.g., breast, lung, colorectal), contributing to tumor growth, metastasis, and chemoresistance. It also drives fibrosis in organs like the liver and lungs by activating profibrotic pathways (e.g., TGF-β). Conversely, WISP1 deficiency is linked to impaired bone formation and insulin resistance. Recombinant WISP1 serves as a tool to explore therapeutic targeting, either by inhibiting its oncogenic effects or harnessing its regenerative potential in tissue engineering.

Studies also highlight its involvement in metabolic syndromes, including obesity and diabetes, via adipose tissue inflammation and insulin signaling modulation. As a secreted protein, WISP1 is being investigated as a biomarker for disease prognosis and a candidate for therapeutic intervention.
