RESUMO
Objective:To investigate the effect of miR-143 on the invasion and migration of B cell lymphoma cells .Methods:The expression of miR-143 in normal bone marrow and lymphoma was detected by qPCR .The expression levels of miR-143 in different cell lines were examined by qPCR .qPCR was used to detect the ability of miR-143 on PAN3.The relationship between miR-143 and PAN3 was detected by double luciferase assay .The effect of miR-143 expression on the migration ability of B cell lymphoma E 6-1 cells was examined by scratch test .The effect of miR-143 expression on the invasion ability of B cell lymphoma E 6-1 cells was exa mined by transwell test.Results:Compared with normal bone marrow ,miR-143 was down-regulated in B-cell lymphoma.Double luciferase assay showed that miR-143 could regulate the expression of PAN 3.Overexpression of miR-143 ,E6-1 cells significantly reduced the ability to attack and migrate.Conclusion:miR-143 can regulate the migration and invasion of B cell lymphoma cells by regulating the expression of PAN3.
