To understand whether HuR is highly expressed in GC, expression of the HuR mRNA and protein were examined in four GC cell lines (MGC-803, BGC-823, SGC-7901, MKN-45) and in non-malignant GES-1 cells by quantitative real-time PCR (qRT-PCR) and western blotting. Here, ELAVL1 is linked to gastric cancer.
