Cysteine-rich protein 61(CCN1/Cyr61) has been implicated as an important mediator in proliferation and metastasis of breast cancer, which indicated that blockage of Cyr61 might be a potent target for breast cancer treatment. However, the antitumor effect of anti-Cyr61 antibodies on breast cancer in vivo has not been reported so far. In this study, we reported the effect and likely mechanism of generated anti-human Cyr61 monoclonal antibodies (mAb) on Cyr61 high expression line MDA-MB-231, known as a highly malignant and invasive human breast cancer cell line, at aspects of proliferation and migration in vitro and in vivo. We found the mAb, denoted as 093G9, revealed inhibitory effects on MDA-MB-231 cell proliferation, migration, and invasion through downregulation of both AKT and ERK phosphorylation in vitro compared with its isotype control. 093G9 also showed significant efficacy on suppressing primary tumor growth and spontaneous lymph node metastasis in in vivo mouse model. The specific epitope recognized by 093G9 was identified to be 140LPNLGCP 146, adjacent to the VWC domain of Cyr61 by Ph.D.-C7C phage library display system. Our study provides direct evidence that Cyr61 can be a potent therapeutic target for patients who bear high Cyr61 expression breast cancer. Furthermore, the mAb, 093G9 developed in our laboratory, has shown a promising therapeutic characteristic in breast cancer. © Springer-Verlag 2011. Source

Background: The different grading systems for diabetic foot disease pose a challenge in clinical decision making because each system fails to accurately reflect the individual course of disease progression. This study attempts to identify laboratory measurements for classifying diabetic foot disease to guide clinical treatment. Methods: The sera of 111 clinically graded diabetic foot patients were measured for several laboratory parameters including serum amyloid A (SAA), C-reactive protein (CRP), and apo A-I. By using the molar sum of CRP and SAA and then dividing by the molarity of apo A-I, an acute phase index was introduced to assess the inflammatory status of the patients. Results: Based on a newly defined acute phase index (API), diabetic foot patients were classified into 3 distinct groups that provide a diagnostic tool complementing the established Texas grading system for clinical decision making. Conclusions: The integration of the serum concentrations of SAA, CRP and apo A-I into an acute phase index (API) offers an opportunity to triage diabetic foot patients who may benefit from personalized medicine. © Copyright.
