Hormones and Signaling focuses on the mechanism of gene regulation at the cellular level. It also covers the way hormones act to modulate gene regulation and animal development.Includes information on: - Nuclear receptors, coactivators, and corepressors - Membrane receptors, kinases, and phosphorylation on cascades - Hormonal regulation of development - Calcium channels and neurotransmitters - Chromatin, transcription factors, and regulation of gene expression - JAK/STAT pathways - Hormone-regulated development and gene "knock-out"
