Figure 1From: Up-regulation of hypoxia inducible factor-1α by cobalt chloride correlates with proliferation and apoptosis in PC-2 cellsThe growth curve of PC-2 cells treated with different dose of CoCl 2 . Cell viability was determined by MTT method. This assay was performed in triplicate. Dose- dependent inhibition of cell growth could be observed after 72 h (P < 0.05, ANOVA analysis).Back to article page
