To assess the contribution of GATA6 to tumour cell dissemination, we injected GATA6-silenced PaTu8988S and GATA6-overexpressing L3.6pl cells—and the respective control cells—into the spleen of athymic Foxn1nu mice and measured human gene expression in the liver by qPCR, an estimate of dissemination. Here, GATA6 is linked to neoplasm.
