2 -Hindgut microorganism symbionts -Oil Spill -Corticosterone 3 Martin Wikelski, Princeton Chap 14. Endocrine System Glands and Hormones Secretions with consequences All cells secrete, but Specialized secretory cells grouped into glands Secrete same specialized substance (e.g., hormone) Nervous System neurotransmitter acts near and fast Other secretions, such as hormones, may act more distantly and over a longer time period 4 2
3 Categories of cellular secretions: Autocrine affect the secreting cell directly Paracrine affect neighboring cells e.g., histamine and inflammation Endocrine release into bloodstream Exocrine release onto epithelial surface e.g., sweat onto skin, bile into digestive system Pheromone exocrine secretion to signal other individuals Neuroendocrine secretion from axon terminal into blood stream 5 Neuroendocrine Systems 9-14 Randall et al Neurosecretory cells secrete neurohormones Axon terminates into neurohemal organ Neurohormones often [effect] other glands/hormones 9-8 Randall et al
4 Hormone Types 1 Amines small (e.g., epi, norepi, thyroid) Eicosenoids from arachodonic acid (prostaglandins etc.) 2 3 Steroid Hormones from cholesterol (e.g., testosterone, estrogen) Peptide Hormones common, large, complex (e.g., insulin, ADH, GH) (autocoids = others like histamine and serotonin) 9-11 Randall et al Hill et al
5 Amines small (e.g., epi, norepi, thyroid) Modified Amino Acids 1. catecholamines (epi, norepi, dopamine; tyrosine) 2. thyroid (lipid soluble; tyrosine) 3. melatonin (tryptophan) 9 Glandular Secretion Response to stimulus Hormone Neurotransmitter Action Potential etc. (e.g., osmolarity and ADH) Storage before Secretion Large molecules easily stored because can t leave readily Small molecules often stored bound to accessory proteins Some molecules actively/continuosly taken into vesicles Steroid hormones (lipid soluble) tend to leak out soon Hydrophobic steroid and thyroid hormones move in blood, bound to carrier proteins 10 5
6 ETC Hill et al Hormone ACTION! (receptors etc.) 1. Lipid Soluble -Steroid and Thyroid Hormones (~long-lived) -Through Membrane - Bind Cytoplasmic Receptors, then to Nucleus - Directly affect transcription (therefore long-term) 2. Lipid Insoluble - Bind cell-surface receptors - Often one or more 2 nd messengers - Amplification - Rapid, short-duration responses 12 6
7 Hormone ACTION! (receptors etc.) 1. Lipid Soluble 2. Lipid Insoluble 9-18 Randall et al Hormone ACTION! (receptors etc.) 2. Lipid Insoluble Hormones and Intracellular Signaling A few receptors with direct catalytic activity, but most via 2 nd messengers : Possible 2 nd messengers: 1. camp, cgmp (cyclic nucleotide monophosphates) 2. IP 3, DAG (diacylglycerol; inositol phospholipids) 3. Ca 2+ ions General Model of Hormone Binding and Intracellular Signaling: 14 7
8 camp (cyclic nucleotide monophosphates) camp GTP/GDP GTP/GDP Protein kinase A 9-20 Randall et al Randall et al
9 Glandular Secretion Secretory Granules/Vesicles similar to synaptic vesicles but usually larger 9-2 Randall et al Exocytosis common release mechanism Regulation via Calcium remember that free cytosolic calcium concentration is correlated with exocytosis (including of NT, hormones, etc.) 17 proinsulin P B C A insulin Fig 14.4 Hill et al
10 Endocrine System Tropic hormones = act on other endocrine tissues (e.g., adrenal cortex, thyroid, gonads) Negative Feedback 9-16 Randall et al Anterior Pituitary 19 Randall et al
11 Endocrine System Major Players: Hypothalamus -(~7 neurohormones) - mostly peptides 9-15 Randall et al Pituitary (9 hormones) 1. Anterior (~nonneuronal) 2. Posterior (~neuronal control) (Portal Vessels) 21 Neuroendocrine System Posterior Pituitary Oxytocin uterine contractions, milk ejection Antidiuretic Hormone (ADH) - water retention in kidney Both are peptide hormones Both are similar and highly conserved 9-17 Randall et al
12 Neuroendocrine System Posterior Pituitary Randall et al ADH Similar, highly conserved peptide hormones 23 Endocrine System Example: In response to cold, fright, pain etc Hypothalamus -corticotropin-releasing hormone Portal vessel 9-15 Randall et al Anterior Pituitary -Adrenocorticotropin (ACTH) Blood Stream Adrenal Cortex (corticosterone; stress hormones) Response (lizard example) 24 12
13 Hormone Effects Adrenal Gland Catecholamines (from medulla) inside Glucocorticoids (from cortex) outside 9-32 Randall et al Fig 14.10, Hill et al Mammalian Stress Response 26 13
14 Glucocorticoids (from adrenal cortex) Released in response to ACTH (Adrenocorticotropin) from Anterior Pituitary Steroid hormones (lipid soluble) derived from cholesterol 1. Reproductive 2. Kidney Function (mineralocorticoids) 3. Glucocorticoids (mobilize a.a.s and glucose, etc.) 9-40 Randall et al Includes Stress Hormones Cortisol, cortisone, corticosterone 27 Fig 14.10, Hill et al
15 Fight/flight, exertion Catecholamines (adrenal medulla) -Epi, Norepi 9-36 Randall et al Secretion regulated by sympathetic preganglionic cholinergic neurons Catecholamine receptors are Alpha and Beta adrenoreceptors Alpha smooth muscle contraction Beta1 cardiac muscle stimulant 29 Beta2 broncho/vaso dilation Vertebrate Reproduction 30 15
16 Reproductive Hormones Steroid Hormones from Adrenal cortex and Gonads See Fig 14.1, Hill et al Hypothalamus GnRH Anterior Pituitary FSH, LH Gonads, Adrenal Cortex 9-39 Randall et al Male Sex Hormones Testosterone and other androgens Released from Leydig Cells in response to LH, FSH FSH binding to Sertoli cells stimulates spermatogenesis 9-46 Randall et al
17 Female Sex Hormones Estrogens Ova created and stored before birth (mammals and birds) Repro cycle in 2 phases: Follicular and Luteal FSH stimulates beginning of follicular phase > development of ovarian follicles 9-47 Randall et al Follicular Phase 1- FSH Causing follicular maturation 2- LH FSH and LH help generate Estrogen (3) 3 6 This Estrogen causes hypothal and ant. pit. to release spike of LH and FSH leading to ovulation (4) (endometrium 5) = release of ovum (6) Randall et al
18 Luteal Phase 7- FSH, LH Estrogen 8- LH changes ruptured follicle into corpus luteum 9- corpus luteum secretes estrogen and progesterone which inhibit FSH, LH release from anterior pituitary by slowing GnRH progesterone leads to richer endometrium 11- without fert. CL degenerates and cycle begins again Randall et al Luteal Phase 12- with fert. Chorionic gonadotropin maintains CL, 7 11 maintaining high levels of 9 estrogen and progesterone; 8 maintaining endometrium; follicular 10 development inhibited Placenta takes over hormone production Randall et al
19 Birth Control Pills? Progesterone and Estradiol mimic early pregnancy and inhibit ovulation 37 19
