Negative feedback loop hypothalamus
WebIn mice, a negative feedback loop featuring Mdm-2 regulates the degradation of p53, a tumor suppressor gene (Oren, 1999). ... will send negative feedback signals to the hypothalamus and the pituitary gland. The result is the reduced production of GnRH and LH, thus decreasing the stimulus for further testosterone production in the testes. Fig. 2. WebThe major endocrine systems are regulated by negative feedback, a process believed to maintain hormonal levels within a relatively narrow range. Positive feedback is often thought to have a destabilizing effect. Here, we present a "principle of homeostasis," which makes use of both positive and negative feedback loops.
