Recent Progress in Hormone Research, Volume 36 presents the proceedings of the 1979 Laurentian Hormone Conference. The book discusses seasonal breeding as nature’s contraceptive; the neuroendocrine control of the menstrual cycle; and the heterogeneity of estrogen binding sites. The text also describes steroid hormone receptors in breast cancer treatment strategy; the multihormonal regulation of casein gene expression at the transcriptional and posttranscriptional levels in the mammary gland; and the hormonal domains of response. The organization and evolution of cloned globin genes; the synthesis, cloning, and expression of hormone genes in Escherichia coli; and ACTH, beta-lipotropin, and related peptides in the brain, pituitary, and blood are also considered. The book further tackles cortoic acids; hormones controlling insect metamorphosis; and the early events in the biosynthesis of secretory and membrane proteins. The text also looks into autoimmunity in endocrine disease and the regulation of peptide hormone receptors and gonadal steroidogenesis. Endocrinologists, reproductive biologists, physiologists, and biochemists will find the book invaluable.
