描述 | The estrogen-related receptors (ERRs) comprise a small group of orphan nuclear receptor transcription factors. The ERRα and ERRγ isoforms play a central role in the regulation of metabolic genes and cellular energy metabolism. ERRβ is the important in the maintenance of embryonic stem cell pluripotency[1]. The selective ERβ agonist AC-186 was evaluated in a rat model of Parkinson's disease induced through bilateral 6-hydroxydopamine lesions of the substantia nigra. In this model, AC-186 prevented motor, cognitive, and sensorimotor gating deficits and mitigated the loss of dopamine neurons in the substantia nigra, in males, but not in females. Furthermore, in male rats, 17β-estradiol, which activates ERβ and ERα with equal potency, did not show the same neuroprotective benefits as AC-186[2].In male rats,AC-186 provided essentially complete reversal of Taxol-induced allodynia at doses of 10 and 30 mg/kg. Repeat dosing experiments showed that no tolerance or desensitization to the effects of AC-186 occurred over 5 days. The analgesic effects of AC-186 were blocked by the ERβ-selective antagonist PHTPP, and coadministration of an ERα-selective agonist (PPT)[3].When ACP-105 is administered in combination with AC-186, they increase the amyloid-β degrading enzymes neprilysin and insulin-degrading enzyme and decrease amyloid-β levels in the brain as well as improve cognition. Interestingly, the androgen receptor level in the brain was increased by chronic treatment with the same combination treatment, ACP-105 and AC-186, not seen with DHT or ACP-105 alone[4]. |
