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

  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
