Five genes, including GTPase, calcium-binding protein (CML), WRKY, MYB44, and GATA transcription factors, were upregulated in the Zn 7d treatment, and five other genes, including those for myelin (MYT1), bZIP, and iron deficiency response (FER) transcription factors and two phosphatases (PP37 and PP51), were upregulated in the Zn 1d treatment. This evidence concerns the gene FER and hyperinsulinemic hypoglycemia, familial, 4.
