Fig. 2From: Zinc-induced upregulation of metallothionein (MT)-2A is predicted by gene expression of zinc transporters in healthy adultsBivariate correlation between total physical activity (MET-minutes/week) and ZIP7 gene expression at baseline for all participants (n = 38). The positive relationship remained after removal of the outlier within the data set (r = 0.43; P = 0.009)Back to article page
