Nutrigenomic profiling identifies ZIP10 (SLC39A10) as a regulator of erythroid zinc homeostasis with genetic associations to anemia risk II

To determine the physiological roles of zinc in erythroid progenitor cells, cellular zinc was restricted by 50 µM DTPA treatment (a zinc chelator) for 24 hours in differentiating G1E-ER4 cells. G1E-ER4 cells induced for differentiation by beta-estradiol were divided into two groups: control and 50 µM DTPA treatment. A sample from cells untreated with beta-estradiol was also included as an undifferentiated group. Overall design: Comparative gene expression profiling of G1E-ER4 cells differentiating under control zinc and zinc restriction (n = 3 biological replicates per treatment), and undifferntiating cells without zinc intervention (n = 1)
