Pigment epithelium-derived factor (PEDF), a glycoprotein with neuronal differentiating activity, possesses anti-inflammatory properties both in cell culture and animal models. However, the relationship between serum levels of PEDF and high-sensitivity C-reactive protein (hs-CRP), one of the representative biomarkers for inflammation in humans, is largely unknown. This study investigated whether serum PEDF levels were associated with hs-CRP in 120 apparently healthy unmedicated Japanese subjects (93 males, 27 females; mean age 58.0 years). All subjects underwent a complete history and physical examination, including blood chemistries, anthropometric and metabolic variables. Multiple regression analysis found that serum hs-CRP, creatinine and triglyceride levels, and the homeostasis model assessment of insulin resistance (HOMA-IR) and body mass index were significantly and independently associated with serum PEDF levels. It is concluded that, serum levels of PEDF are associated with serum levels of hs-CRP independently of anthropometric, metabolic and renal function variables. The results also suggest that serum PEDF levels may be elevated as a counter-system against subclinical inflammation.
