Expression of Ki-67 following treatments with different doses of krill oil. A The expression of Ki-67 in tumours following in vivo treatments with different doses of krill oil compared to the untreated group was determined using a monoclonal antibody for Ki-67. B The fluorescence intensity of Ki-67 expression in tumours following treatments with different doses of krill oil compared to the untreated group. C Quantification of Ki-67-positive cells based on 8 images per preparation at 20 × magnification within a total area of 2mm². The thickness of tumour cross-sections = 10 µM. N = 5 mice per group. The results are expressed as mean ± SEM, **P < 0.01, and ***P < 0.001 compared to the untreated group; ^^^P < 0.001 compared to 5% krill oil-treated group; ^#P < 0.05 compared to 10% krill oil-treated group
