Study Notes
Hormone Regulation
- Regulating hormone availability can be achieved by controlling expression and secretion of carrier proteins that bind to hormones like steroids.
Hormone Binding Mechanisms
- One class of hormone binding triggers the simultaneous dislodging of a transcriptional co-repressor and recruitment of a co-activator.
Regulation of Gene Expression
- This mechanism allows for a wider dynamic range of regulation of genes targeted by the hormone.
- It enables efficient responsiveness of target cells to hormonal action.
Feedback Control Loops
- Feedback control loops facilitate the regulation of hormone action by allowing target cells to "feed back" to the endocrine organ.
- These loops provide a diagnostic strategy for evaluating patients with suspected endocrine disorders.
