IL-11 expression related with MTA2 in SGC-7901 and BGC-823 cells. A: IL-11 expression was detected by real-time PCR. B: IL-11 protein was detected by western blot and ELISA. C: IL-11 expression in SGC-7901 and BGC-823 xenografts was detected by IHC. D: IL-11 mRNA expression was reduced by SAHA in both SGC-7901/NC cell and BGC-823/MTA2 cell.
