ABSTRACT
Objective@#To construct the mutants of ARID1A gene, which is an important component in human chromosomal remodeling complex Switch/Sucrose Non Fermentable (SWI/SNF), and identify their overexpression in liver cancer HepG2 cells.@*Methods@#Overlap PCR was used to construct domain truncated mutantss pcDNA6-ARID1A/ΔARID and pcDNA6-ARID1A/ΔD UF3518 based on wild type plasmids pcDNA6-ARID1A. Lipofectionmethod was used to transfect the wild type and mutants into HepG2. Real-time PCR and western blotting were used to confirm the overexpression of ARID1A and the mutants.@*Results@#SDS-PAGE and sequencingresult confirmed the successful construction of pcDNA6-ARID1A/ΔARID and pcDNA6-ARID1A/ΔDUF3518. Real-time PCR and western blottingresult confirmed the overexpression of both mRNA and protein of wild type ARID1A and ARID1A/ΔARID. The mRNA levels indicated that ARID1A/Δ DUF3518 were overexpressed, but the protein levels were quite low.@*Conclusions@#Functional domain truncated mutants of ARID1A were successfully constructed. Overexpression of wild type ARID1A and ARID1A/ΔARID in liver cancer HepG2 cells was successful. Loss of ARID1A/ΔDUF3518 protein suggest that DUF3518 may contribute to the protein structure stability.
