Production of Corticosteroid Hormones in Vitro by Adrenals in Rats with Streptozotocin-Induced Diabetes

Abstract: We studied baseline and ACTH-stimulated in vitro production of corticosteroids by rat adrenals. Production of the basic corticosteroids pregnenolone (early precursor in corticosteroid synthesis), progesterone (intermediate precursor in synthesis of gluco- and mineralocorticoid hormones), and corticosterone (major glucocorticoid hormone in rodents) in animals with streptozotocin-induced diabetes was enhanced by 1.8-2.0 times in comparison with the control animals. Addition of ACTH to the incubation medium stimu… Show more

“…1). This difference between non-diabetic and STZ animals after acute treatment with ROF is not surprising as several studies demonstrate that experimental T1DM induces encephalopathy in these animals characterized by increased oxidative stress and neuroinflammation, chronic increase in the long-term activity of the hypothalamus-pituitary-adrenocortical (HPA) axis [57,60], dysregulation of the neurotransmitter systems, impaired synaptic plasticity, and neurogenesis [1][2][3][4][5][6][7][8][9][10][11][12]. Thus, a longer treatment would be necessary for a beneficial effect to occur.…”

“…Проте більшість робіт, присвячених вивченню активності гіпофізарно-надниркової системи при ЦД, досить часто мають суперечливий характер [8]. Так, деякі дослідники вказують на нормальний рівень кортизолу та його циркадіанні ритми у пацієнтів з декомпенсованим ЦД [9]. Натомість інші автори [10] стверджують, що у підлітків і молодих людей з ЦД 1-го типу спостерігається під-вищений рівень вільного кортизолу, але не адренокортикотропного гормону (АКТГ), при цьому в нічний час відмічають меншу чутливість кори надниркових залоз до ендогененного АКТГ, що вказує на порушення циркадіанних ритмів у функціонуванні гіпофізарно-надниркової ситеми.…”
