TRH

Stimulate TSH from anterior pituitary. Stimulate PRL from anterior pituitary.

GHRH

Stimulate GH from anterior pituitary.

GnRH

Stimulate FSH from anterior pituitary. Stimulate LH from anterior pituitary.

CRH

Stimulate ACTH from anterior pituitary.

OT

Uterine contractions, lactation

ADH

Promote water re-absorption and increasing blood volume

Melatonin

Antioxidant, monitor the circadian rhythm

GH

Stimulate growth and cell reproduction. Stimulate IGF1 from liver

TSH

Stimulate T3 and T4 synthesis and from thyroid. Stimulate iodine absorption

ACTH

Stimulate corticosteroid and androgen from adrenocortical cells

FSH

In Female: Stimulate maturation of ovarian follicles
In Male: Stimulate maturation of seminiferous tubules, spermatogenesis, and production of androgen-binding protein from testes

LH

In Female: Stimulate ovulation, formation of corpus luteum
In Male: Stimulate testosterone synthesis from testes

PRL

Stimulate milk synthesis

MSH

Stimulate melanin synthesis and release from skin/hair melanocytes

OT

Uterine contraction, lactation

ADH

Promotes water re-absorption and increases blood volume

T3

Increase metabolic rate and protein synthesis

T4

Increase metabolic rate and protein synthesis

Calcitonin

Reduces blood Ca2+

PTH

Regulates Ca2+, Mg2+, and HPO4 2-

Insulin

Intake glucose, glycogenesis and glysolysis in liver and muscle from blood, intake of lipid and synthesis of TG in adipocytes

Glucagon

Glycgenolysis and gluconeogenesis in liver, increase blood glucose level

Somatostatin

Inhibit release of insulin and glucagon

Pancreatic polypeptide

Inhibit somatostatin secretion and pancreas secretion activities

Glucocorticoids

Stimulate gluconeogenesis, fat breakdown, inhibit protein synthesis, glucose uptake in muscles and adipose tissue, immunosuppressive, anti-inflammatory

Mineralocorticoids

Stimulate active Na+ and water re-absorption in kidney, thus increase blood volume and pressure. Stimulate K+ and H+ secretion into kidney and subsequent excretion

Androgens

In Female: Promote libido, converted to estrogen
In Male: Small amount

Epinephrine

Fight-or-flight response

Norepinephrine

Fight-or-flight response

Testosterone

Regulates production of sperm

Progesterone

Support pregnancy

Estrogen

Regulate menstrual cycle, prepare for lactation

Thymosin, thymic humoral factor, thymic factor and thymopoietin. Effect: Promote maturation of T cells
