Abstract

OBJECTIVE

To determine the mechanism of peritoneal fibrosis of peritoneal mesothelial cells by high glucose.

METHODS

The third passage human peritoneal mesothelial cells (HPMCs) from primary culture were divided into a control group (F(12)) and high glucose groups (F(12)+4% glucose) in different times (24, 48 h). The cell proliferation was assayed by the method of MTT (methylthiazoletetrazolium). The cell damage was measured by LDH (lactate dehydrogenase). The protein expression of fibronectin (FN), transforming growth factor-beta1(TGF-beta(1)) and connective tissue growth factor (CTGF) were detected by ELISA. The mRNA expression of FN, TGF-beta(1) and PAI-1 were detected by RT-PCR.

RESULTS

High glucose suppressed the cell proliferation. The result of MTT showed that compared with the control group, the value of OD of high glucose groups at 24 or 48 h decreased significantly (P<0.01 or 0.01); The cell damage was enhanced in high glucose groups, at 24 or 48 h compared with the control group at the same time (all P<0.01). The protein expressions of TGF-beta(1), CTGF and FN in supernate fluid of cell culture were significantly enhanced when high glucose stimulated the HPMCs in the high glucose groups at 24 or 48 h compared with the control group at the same time (P<0.05 or 0.001). The expressions of FN, TGF-beta(1) and PAI-1 mRNA were upregulated in 24 h high glucose group compared with that of 24 h control group.

CONCLUSION

High glucose can suppress the HPMC proliferation and damage HPMCs. Increase of TGF-beta(1), CTGF, FN and PAI-1 of HPMCs stimulated by high glucose can promote the synthesis and decreased degradation of extracellular matrix, which might be related with the mechanism of peritoneal fibrosis of peritoneal mesothelial cells by high glucose.
