In this study, we observed that MR16-1, an interleukin-6 inhibitor, recovered phosphatidylcholine containing docosahexaenoic acid at the injury site after spinal cord injury in mice model by using imaging mass spectrometry. The current drugs for improving motor function of the limbs lost due to spinal cord injury (SCI) are ineffective. Development of new drugs for spinal cord injury is desired. MR16-1, an interleukin-6 inhibitor, is found to be effective in improving motor function after spinal cord injury in mice model. Thus, we examined the molecular mechanism in more detail. Therefore, the purpose of this study was to analyze the molecular changes in the spinal cord of the SCI mice treated with MR16-1 using imaging mass spectrometry.Summary Statement
Introduction
We investigated the rates of expression of bone morphogenetic protein-2 (BMP-2) in 29 adult patients with high-grade malignant fibrous histiocytoma of soft tissue, using the BMP-2-specific monoclonal antibody, AbH3b2/17, and found that they ranged from 1.9% to 78.9%. The survival at five years of the groups expressing high (≥30%) and low (<
30%) levels of BMP-2 was 85.7% and 36.3%, respectively. Multivariable analysis showed that only BMP-2 had prognostic significance for continuous disease-free survival and for overall survival (p <
0.05). Our findings indicate that over-expression of BMP-2 in malignant fibrous histiocytoma of soft tissue is the most reliable prognostic indicator of the parameters assessed.
