Abstract
Aim To study effects of pioglitazone on cardiac fibroblast proliferation induced with high glucose and high insulin.Methods The neonatal rat cardiac fibroblasts were cultured and treated with different factors.The cellular number was determined by crystal violet uptake;the DNA synthesis was assayed with thymidine intake method;the percentage of S+G_2+M in the cell cycle was determined by flow cytometry.Results Pioglitazone inhibited the cell number、DNA synthesis and the percentage of S+G_2+M in the cell cycle of cultured cardiac fibroblasts induced with high glucose and high insulin.Conclusion Pioglitazone inhibits cardiac fibroblast proliferation induced with high glucose and high insulin and the effective mechanism of pioglitazone on cardiac fibroblast proliferation needs further study.
