ABSTRACT
[ ABSTRACT] AIM:
To investigate the SALL4 expression, proliferation and apoptosis in the LNCaP cells after transfection of SALL4 siRNA.METHODS:
The expression of SALL4 at mRNA and protein levels was detected by real-time PCR and Western blotting.MTS assay, colony formation assay and flow cytometry were used to determine the prolifer-ation, colony formation ability and apoptosis of the LNCaP cells.The effect of SALL4 on the expression of Bax and Bcl-2 was analyzed by Western blotting.RESULTS:
Compared with negative control group, the expression of SALL4 at mRNA and protein levels in LNCaP cells was down-regulated by transfection of SALL4 siRNA ( P<0.05 ) .The proliferation rate and colony formation ability were decreased, while apoptosis rate increased in si-SALL4 group (P<0.05).Higher expres-sion of Bax and lower expression of Bcl-2 in si-SALL4 group were observed ( P<0.05 ) .CONCLUSION:
Down-regula-tion of SALL4 by siRNA not only suppresses LNCaP cell proliferation and colony formation, but also inhibits Bcl-2 expres-sion and activates Bax expression to induce apoptosis.
