Prognostic role of the recepteur d'origine nantais (RON) expression in primary high-grade osteosarcoma.

Background: Osteosarcoma is a common primary malignant bone tumor susceptible to distant metastasis. The clinical outcome for patients remains poor due to the resistance to chemotherapy and lacking effective therapeutic targets. Recepteur d'origine nantais (RON), a transmembrane protein of the c-MET proto-oncogene family, has been reported to contribute to the malignant progression and bone metastasis in several tumors.

Clinicopathological and prognostic values of ErbB receptor family amplification in primary osteosarcoma.

Osteosarcoma is a malignant bone tumor with extremely high invasion, metastasis and mortality. The prognosis of patients with osteosarcoma remains poor. The ErbB receptor family was found to be overexpressed in human cancers and associated with poor prognosis.

Clinicopathological and prognostic values of fibronectin and integrin αvβ3 expression in primary osteosarcoma.

Background: Osteosarcoma is a malignant bone tumor with a high potential for lung metastasis, and the prognosis for patients with metastatic disease is very poor. The interaction between fibronectin (FN) and integrin αvβ3 in soft-tissue sarcoma promotes cell migration, invasion, and lung metastasis. This study aimed to investigate the prognostic significance of FN and αvβ3 in osteosarcoma.

Prognostic significance of the expression of HER family members in primary osteosarcoma.

The prognosis of patients with metastatic osteosarcoma is poor and has shown no significant improvement in nearly 20 years. The human epidermal growth factor (EGF) receptor (HER) family is frequently overexpressed in the majority of human carcinomas, and is involved in promoting the proliferation and survival of cancer cells. However, the role of EGFR and HER-2 expression in osteosarcoma survival remains controversial and no previous study has simultaneously investigated the association of the expression of all the four HER family members with the prognostic significance of osteosarcoma.

Framework-structured weak ferromagnets.

Framework-structured weak ferromagnets are new rising stars in molecule-based magnetic materials. The framework structures are powerful carriers for long-range ordering of spins. And weak ferromagnetism due to spin canting is an effective approach for magnets because of its frequent occurrence and desired spontaneous magnetization as long as the canting angle γ is large enough.
