Effect of Lp(a) on human mesangial cell proliferation, adhesion and migration

OBJECTIVE: The renal disease is commonly associated with hyperlipidemia and correlates with glomerular accumulation of atherogenic lipoproteins and mesangial hypercellularity. Therefore, in this study, the authors investigated a possible growth stimulatory effect and mode of action of lipoprotein(a)...

Zusammenfassung:OBJECTIVE: The renal disease is commonly associated with hyperlipidemia and correlates with glomerular accumulation of atherogenic lipoproteins and mesangial hypercellularity. Therefore, in this study, the authors investigated a possible growth stimulatory effect and mode of action of lipoprotein(a) [Lp(a)] in human mesangial cells HMC, and the effect of Lp(a) on adhesion and migration in human mesangial cells
METHODS: The DNA synthesis of HMC was measured by (3)H-thymidine incorporation. The cell adhesion was detected by the expression of vinculin by means of indirect immunofluorescence. The cell migration was observed under the microscope
RESULTS: The incubation of HMC with Lp(a) for 24 hours induced a significant dose-dependent proliferation of HMC [Lp(a): 5 microg, 10 microg, 25 microg, 50 microg/ml vs. control 0 microg/ml; (3)H-TdR incorporation (x 10(3)cpm): 1.69 +/- 0.48, 3.59 +/- 0.68, 4.14 +/- 0.78, 4.05 +/- 0.55 vs. 1.64 +/- 0.31, P < 0.01]. The vinculin staining by indirect immunofluorescence showed positive result when HMC was incubated with 10 microg/ml Lp(a) for 24 hours, while vinculin was negative when HMC was incubated with 0 microg/ml Lp(a) as the control of the study. The incubation of HMC with 10 microg/ml Lp(a) for 72 hours demonstrated significant cell migration effect compared to the control of 0 microg/ml. (16.2/LP vs. 2.4/LP, P < 0.01)
CONCLUSION: Lp(a) could stimulate a proliferation, adhesion and migration effect on human mesangial cells
