ABSTRACT
Objective:
To investigate the effect of blocking the expression of receptor activity modifying protein 1 (RAMP1 )on calcito-nin gene-related peptide(CGRP)-induced MG-63 cell proliferation.Methods:
RAMP1 siRNA was synthesized and screened by tran-scription in vitro.The subcultured MG-63 cells were divided into the following groupsRAMP1 siRNA interference group,empty vector group and blank control group.The mRNA expression and the membrane distribution changes of the calcitonin receptor-like receptor (CRLR)and the receptor component protein (RCP)in MG-63 cells were examined by real-time PCR and immunofluorescence method respectively.Results:
RAMP1 and CRLR mRNA and the fluorescence intensity of MG-63 cells decreased after transfection by RAMP1 siRNA(P <0.05).In RAMP1 interference group,the expression of RCP mRNA and the fluorescence intensity were higher than those in the other two groups(P <0.05).After RAMP1 siRNA interference,the proliferation of MG-63 cells was inhibited(P <0.05).Conclusion:
RAMP1 siRNA transfection may reduce CRLR expression and inhibite the proliferation of MG-63 cell.
