Table 2 Zinc and iron homeostatic markers in blood from obese and non-obese individuals

From: Gene expression of the zinc transporter ZIP14 (SLC39a14) is affected by weight loss and metabolic status and associates with PPARγ in human adipose tissue and 3T3-L1 pre-adipocytes

  Obese individuals before weight loss Non-obese controls Obese individuals after weight loss
  Women Men Women Men Women Men
Zn (μmol/L) 13.3 (±1.7) 14.3 (±1.3) 11.8 (±0.7)*** 13.3 (±0.1) 12.8 (±1.7) 14.5 (±1.4)
Fe (μmol/L) 17.4 (±5.5) 21.9 ( ±6.9) 15.8 (±5.2)** 22.7 (±5.1) 13.1 (±5.6) 18.8 (±5.2)
Ferritin (μg/L) 61 (±40)**** 247 (±105)* 49 (±43) 120 (±78) 69 (±51)*** 243 (±111)*
Transferrin (μmol/L) 36.0 (±3.6) 33.7 (±3.9) 34.4 (±6.8) 34.2 (±4.7) 33.6 (±3.3) 32.2 (±3.8)
  1. Total Zn, Fe, ferritin, and transferrin concentrations in blood from obese individuals (before and after weight loss) and from non-obese controls. Data are presented as mean ± standard deviation. *P < 0.05, obese individuals vs. non-obese controls of the same gender. **P < 0.05, ***P < 0.01, ****P < 0.001, when comparing women vs men within the same weight group. No significant differences were found when comparing obese individuals before and after weight loss
