Table 4 Comparison of tissue CCS expression between Zn-30 rats and responders and non-responders for plasma Cu1,2

From: Copper Chaperone for Cu/Zn Superoxide Dismutase is a sensitive biomarker of mild copper deficiency induced by moderately high intakes of zinc

  1. 1 Values in a column without a common letter differ, P < 0.05. Values are means ± SEM.
  2. 2 n values are in parentheses.
  3. 3 Rats from diet groups Zn-60, Zn-120 and Zn-240 characterised as non-responders for plasma Cu.
  4. 4 Rats from diet groups Zn-60, Zn-120 and Zn-240 characterised as responders for plasma Cu.
