Estrogen-induced downregulation of TASK-1 expression through estrogen receptor β in N2A cells
1Department of Neuroscience, South-Central University for Nationalities, 182 Minyuan Road, Wuhan, 430074, China.
Background:
Our previous data revealed that reduction of TASK-1 expression, as a consequence of exposure to 17β-estradiol, could participate in neuroprotective effects in N2A cells. However, it is unclear which estrogen receptor underlies these effects of 17β-estradiol.
Methods And Results:
In this study, the knockdown experiments are carried out to clarify the estrogen receptor responsible for effects of estrogen on TASK-1 channels. Subsequently, data from QPCR measurements reveal that estrogen receptor β (ERβ), but not estrogen receptor α, serves as a binding target for 17β-estradiol after a 48-h treatment.
Conclusions:
The current result suggests the implication of the ERβ-dependent manner in the pro-proliferative action of estrogen via TASK-1 channels.

Target Cell Response to Hormones
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...
