Uses of PI in therapy are usually associated with a decrease in body weight and dyslipidemia. Acylation stimulating protein ASP is a protein synthesized in adipocytes to increase triglycerides biosynthesis for that the relation of PI and ASP to adipogenesis is tested in this work. ASP expression was increased during 3T3-L1 differentiation and reached a peak at day 8 with cell maturation. Addition of PI during adipocytes differentiation dose dependently and significantly p inhibited the degree of triglycerides TG accumulation. Moreover presence of ASP 450 ng mL in media significantly p stimulated the degree of TG accumulation and there was additive stimulation for ASP when added with insulin 10 1 g mL . Finally when ASP in different doses Low Medium 45 and High 450 ng mL incubated with a dose of 150 PI ASP partially inhibited the PI-inhibited adipogenesis and TG accumulation. The results in this study show that PI inhibit lipids accumulation and confirm role of ASP in TG biosynthesis and adipogenesis.
