Programmed cell death 10 can be used as a potential biomarker for ankylosing spondylitis diagnosis and treatment.

Abstract

Diagnostic study. Programmed cell death 10 (PDCD10) is a new versatile molecule involved in signal transduction regulation in angiogenesis and tumors. The potential of using it as a biomarker for the diagnosis of ankylosing spondylitis (AS) is still unknown. University laboratory in Gannan Medical University, China. Expression of PDCD10 was analyzed using clinical samples of patients with AS and Gene Expression Omnibus (GEO) data GDS5231. To explore its function, PDCD10 was upregulated and downregulated in synovial cells. Spearman analysis was used to study the association between PDCD10 and the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and the modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS). The Receiver operating characteristic (ROC) curve was applied to evaluate the sensitivity and specificity of PDCD10. Expression of PDCD10 was upregulated in patients with AS and it is capable of promoting the calcification of synovial cells. A positive association between PDCD10 and the BASDAI and the mSASSS was observed. The area under the ROC curve (AUC) of PDCD10 was 82% with a 95% confidence interval of [0.772, 0.868]. PDCD10 is upregulated in patients with AS and it can promote the calcification of synovial cells in vitro. PDCD10 is positively associated with outcome parameters of AS. ROC analysis of PDCD10 suggests that it can be used as a biomarker for the diagnosis and treatment of AS.
