Significantly high proliferation in 24-h reattached gRNA1 cells, deduced by high Ki67 staining and significantly higher mRNA expression of KRT14, is consistent with the in vivo results where gRNA1 cells injected into mice produced larger ascites volumes than mice injected with either control or parental cells and had more extensive tumour burden and tumour infiltration in peritoneal organs (liver and pancreas) than tumours derived from either control or parental cell lines. The gene discussed is MKI67; the disease is neoplasm.
