Re then expressed as imply SE. One way ANOVA followed by post-hoc Dunnett’s test was applied for multiple comparisons, while Student’s t test was employed for comparing the two classes of information shown in figures. A P 0.05 worth was deemed statistically considerable. The half Inhibitory Concentration (IC50) of metformin was calculated on cell count, MTS and thymidine-incorporation dose-response curves applying Origin computer software 6.1 version (OriginLab Corporation, Northampton, MA).Perri G, Terzolo M.
