Abstract

Objective: To investigate the levels of signal peptide-CUB-EGF domain-containing protein(SCUBE 1 and 3) in rheumatoid arthritis (RA).
Materials and Methods: Twenty eight RA patients and 28 healthy volunteers were included in the study. SCUBE-1, SCUBE-3, Vascular Endothelial Growth Factor (VEGF), Matrix Metalloproteinase-9 (MMP-9), CD-40L, Interleukin-6 (IL-6) levels, which are important markers in angiogenesis, were measured twice, at baseline and after the treatment.
Results: Compared to the healthy group, only MMP-9, one of the angiogenesis markers, was elevated in the patient group (p>0.05). After treatment, a significant decrease was observed in VEGF levels (p0.05).
Conclusion: In our study, RA patients responded to treatment with clinical improvements. Although there were differences in the levels of MMP and VEGF, there was no association with the disease in SCUBE.
