The mood cycle hypothesis: possible involvement of steroid hormones in mood regulation by means of Na+, K+-ATPase inhibition.
The mood cycle hypothesis attempts to propose a model for mood regulation based on current data. The hypothesis contends that steroid hormones inhibit sodium-potassium adenosine triphosphatase (Na+, K+-ATPase; Na+ pump) in the hypothalamus, either directly or by converting into digitalis-like compounds. This inhibition stimulates beta-endorphin (beta-E) secretion, which is normally construed as elevated mood. In turn, beta-E inhibits steroid secretion, thus completing negative feedback loops. These loops are collectively termed the mood cycle.
