ABSTRACT
AIM:
To evaluate the effects of all-trans retinoic acid (atRA) on the proliferation in cultured mouse cerebral microvascular endothelial cells (bEnd.3) .METHODS:
Cultured cells were divided into five groups randomly, one as control group, the other four groups were 10-9, 10-8, 10-7 and 10-6 mol/L group. Effects of atRA on proliferation in bEnd.3 cells were detected by flow cytometry and immunocytochemitry of PCNA and MTT at 24 h, 48 h and 72 h. The effects of atRA (10-6 mol/L group) on the expressions of angiogenic genes in bEnd.3 cells were studied using microarray.RESULTS:
The results of MTT and flow cytometry showed that all- trans retinoic acid at concentration of 10-6 mol/L significantly inhibited the proliferation of bEnd.3 cells. Immunocytochemical staining showed the expression of PCNA was markedly decreased in bEnd.3 cells at 24 h after treatment with atRA. Microarray results demonstrated that there were 11 down - regulated angiogenic genes and 2 up - regulated angiogenic genes in 10-6mol/L atRA group.CONCLUSION:
All - trans retinoic acid at concentration of 10-6mol/L may significantly inhibit the proliferation of bEnd.3 cells treated for 24 h ire vitro via down-regulation of angiogenic genes and PCNA expression.
