Impact of Cadmium on Intracellular Zinc Levels in HepG2 Cells: Quantitative Evaluations and Molecular Effects

Table 1

Cd 0.1 µM	Cd 10 µM	Zn 10 µM	Zn 50 µM	Zn 170 µM
23.17 ± 14.01	93.03 ± 6.55^*	12.57 ± 10.24	21.37 ± 4.24	225.22 ± 24.59^*

Fluorescence intensities (arbitrary units) of labile zinc in cadmium- or zinc-treated HepG2 cells. The results are expressed as increment of basal (control) values ± SD of at least three independent biological replicates. ^*P < 0.05 significantly different (Student’s -test) from the corresponding Cd or Zn treatment at lower concentration.
