Abstract
Background/Aims: Hepatic fibrosis is a wound-healing process in the chronically injured liver. Clinical application of platelet-rich plasma (PRP) is of considerable interest for wound healing and regeneration. In view of the regeneration effect of PRP, we designed this study to explore the hypothesis that PRP could play a role in improving the biochemical and molecular changes that occur in liver fibrosis induced by dimethylnitrosamine (DMN) in rats. Methods: Four groups were studied: control, PRP control, DMN (liver fibrosis), and DMN+PRP groups. Serum liver enzymes (alanine amino transferase ALT, aspartate amino transferase AST, gamma glutamyl transferase GGT, and lactate dehydrogenase LDH), and liver hydroxyproline content were measured colorimetrically.Interleukin-8 (IL-8) and B-cell lymphoma (Bcl2) were determined by enzyme-linked immunosorbent assay. And the expression levels of alpha-smooth muscle actin (α-SMA) ,transforming growth factor (TGF-β), and nuclear factor kappa B1(NF-қB1) were evaluated by quantitative real-time polymerase chain reaction. Results: Our results showed that PRP markedly improved the DMN-induced changes in liver enzymes accompanied by a significant decrease in liver hydroxyproline content and IL-8 level induced by DMN, and an increase in the anti-apoptotic marker Bcl-2. PRP also showed significant down-regulation of fibrosis-related genes α-SMA and TGF-β and a significant decrease in the inflammatory marker NF-қB1. Conclusion: Based on these encouraging results, we consider that PRP could be a promising new agent for liver regeneration and alleviation of fibrosis.
