The analysis of the molecular profile (Fig. 3A) confirmed that somatotropinomas expressed high levels of GH (19.586 ± 113.743 copies/adjusted by ACTB) and low levels of other hormones, being PRL (0.07 ± 0.147 copies/adjusted by ACTB) and POMC (0.01 ± 0.017 copies/adjusted by ACTB) the most expressed among them. The gene discussed is GH1; the disease is growth hormone-producing pituitary gland neoplasm.
