Aberrant ADAM10 expression correlates with osteosarcoma progression

Ren Zhao, Dongjing Ni, Yi Tian, Bing Ni, Aimin Wang
2014 European Journal of Medical Research  
Osteosarcoma is the most common type of bone cancer and is notorious for its rapid progression. The Notch signaling pathway has recently been shown to be involved in osteosarcoma. As a major sheddase of Notch receptors, ADAM10 has been implicated in many types of cancers, but its role in osteosarcoma has not been investigated. Previous studies have shown that the expression of CD31 was significantly elevated in metastatic osteosarcoma; however, its expression in nonmetastatic groups is not
more » ... . In addition, the mysterious multinucleated giant cell in giant cell-rich osteosarcoma was previously regarded as an osteoclast-like cell, but its exact identity is unclear. Method: Tissue chip samples from 40 cases of nonmetastatic osteosarcoma were stained for cytoplasmic ADAM10, activated Notch1 and CD31. Osteoclasts in tumor sections were also stained for tartrate-resistant acid phosphatase (TRAP). Results: Immunofluorescence staining revealed that ADAM10 expression significantly increased with the progression of osteosarcoma as well as in osteoblastic osteosarcoma, whereas the expression of the Notch intracellular domain (NICD) and CD31 was not significantly altered between different pathological stages. In addition, multinucleated giant cells in giant cell-rich osteosarcoma were also found to coexpress CD31, ADAM10 and NICD, but were negative for TRAP staining. Conclusions: Our results highlight the importance of ADAM10 in the progression of osteosarcoma and suggest that the protein might be a potential therapeutic target in osteosarcoma treatment. This study also demonstrates that the multinucleated giant cell is an angiogenic tumor cell, rather than an osteoclast, and involves ADAM10/ Notch1 signaling activation.

Understanding of multi-stage R-phase transformation in aged Ni-rich Ti–Ni shape memory alloys

Y. Zhou, G. Fan, J. Zhang, X. Ding, X. Ren, J. Sun, K. Otsuka
2006 Materials Science & Engineering: A  
An abnormal three-stage martensitic transformation behavior (one-stage R and two-stage B19 ) has been found in Ni-rich Ti-Ni alloys when aged at intermediate temperatures (350-500 • C).  ...  This strange behavior was successfully explained by considering the kinetics of Ti 3 Ni 4 precipitation in polycrystalline samples.  ...  In addition, by referring to the phase diagram of Ti-Ni system, it can be seen that the solubility of Ni in Ti-Ni alloys decreases as the temperature decreases.  ...
