Abstract Oral cavity cancer is the sixth-leading cancer worldwide, which has become one of the important factors affecting oral health. The morbidity of oral squamous cell carcinoma(OSCC) accounts for nearly 80% of oral cavity cancer. The pathogenesis and prevention of OSCC have become a hot topic in this field. Previous studies have shown that bone morphogenetic proteins(BMPs) participated in the development, invasion and metastasis of gastric and bone cancers, thereby impacting the prognosis of the patients. Recent studies have found that BMPs also play a key role in the development, progression, metastasis, and invasion of OSCC, This review therefore summarizes the correlation and molecular mechanism between BMPs and the biological behavior of OSCC.

Objective: To summarize the active changes of Wnt signaling pathway in osteoarthritis (OA) as well as the influence and mechanism of dual-targeted regulation on cartilage and subchondral bone and the role of crosstalk between them on OA process. Methods: The relevant literature concerning the articular cartilage, subchondral bone, and crosstalk between them in OA and non-OA states by Wnt signaling pathway in vivo and vitro experimental studies and clinical studies in recent years was reviewed, and the mechanism was analyzed and summarized. Results: Wnt signaling can regulate the differentiation and function of chondrocytes and osteoblasts through the classic β-catenin-dependent or non-classical β-catenin-independent Wnt signaling pathway and its cross-linking with other signaling pathways, thereby affecting the cartilage and bone metabolism. Moreover, Wnt signaling pathway can activate the downstream protein Wnt1-inducible-signaling pathway protein 1 to regulate the progress of OA and it also can be established gap junctions between different cells in cartilage and subchondral bone to communicate molecules directly to regulate OA occurrence and development. Intra-articular injection of Wnt signaling inhibitor SM04690 can inhibit the progress of OA, and overexpression of Wnt signaling pathway inhibitor Dickkopf in osteoblasts can antagonize the role of vascular endothelial growth factor work on chondrocytes and inhibit the catabolism of its matrix. Conclusion: The regulation of metabolism and function of cartilage and subchondral bone and crosstalk between them is through interactions among Wnt signaling pathway and molecules of other signaling. Therefore, it plays an vital role in the occurrence and development of OA and is expected to become a new target of OA treatment through intervention and regulation of Wnt signaling pathway.
