ABSTRACT
BACKGROUND: The current study was designed to highlight the effects of heterologous platelet-rich plasma (PRP) on deteriorated hepatic tissues and impaired glucose metabolism of alloxan-induced diabetic mice. METHODS: 30 male mice were divided into a control (CG), PRP (PG), diabetic (DG), and two treated groups (T1G and T2G). PG was given PRP treatment (0.5 ml/kg body weight) twice a week for four weeks. DG, T1G and T2G were given alloxan (150 mg/kg) to induce diabetes. After confirmation, PRP treatment was given to T1G and T2G for two and four weeks respectively while DG was left untreated. Upon completion of the said experimental period, liver samples were taken for histological and gene expression analyses. RESULTS: The study found that the liver tissue of the DG group showed signs of damage, including hepatocyte ballooning, sinusoid dilatation, and collagen deposition. However, these changes were significantly reduced in both T1G and T2G groups. The expression of several genes related to liver function was also affected, with upregulation of Fbp1 and Pklr, and downregulation of Pck1 in the DG group. PRP treatment restored Fbp1 expression and also increased the expression of glycolytic pathway genes Hk1 and Gck, as well as Wnt signalling pathway genes Wnt2, Wnt4, and Wnt9a in both treated groups. CONCLUSION: Current study revealed that heterologous PRP may partly alleviate high glucose levels in diabetics possibly by mediating glucose metabolism via inhibition of Wnt signalling pathway.
