Fricker et al. reported that an increase in the thyroid hormone content in the blood of patients with hyperthyroidism can promote the synthesis of Na+ - K+ - ATPase in many cells of the body, increase the basal metabolic rate and oxygen consumption, accelerate the cell renewal rate/metabolic rate, and promote the secretion of CysC by nucleated cells, thereby accelerating the production rate of CysC. Here, TG is linked to hyperthyroidism.
