β-adrenoceptor antagonists regulate cell cycle distribution in vitro cultured PanCa cells and limited prevented tumour progression in vivo. The cell cycle distribution of PanCa cells in response to β-adrenoceptor antagonists (A), MIA PaCa-2 and BxPC-3 cells were untreated (control) or treated with β-adrenoceptor antagonists: 100 μM metoprolol and 100 μM ICI118,551 for 24 h. β-adrenoceptor antagonists limited tumor development in BALB/c athymic nude mice (B), the black dashed line was used to label the tumor range. H&E staining statistical graph of tumor range showed that the proliferation of PanCa cells was strongly suppressd in renal capsule xenografts after ICI118,551 treatment compared to non-treated cells (P < 0.05). *P < 0.05 when compared with controls.
