Estrogen - Wikipedia
Estrogen (also spelled oestrogen in British English; see spelling differences) is a category of sex hormone responsible for the development and regulation of the female reproductive system and secondary sex characteristics.
Estrogen Hormone Biology - PMC
Estrogen works through several possible cellular mechanisms to mediate its biological responses as shown in Figure 1. These include two major cellular actions involving the receptors: rapid non-genomic effects and genomic activities (Hewitt et al., 2016).
Estradiol - Wikipedia
Estradiol (E2), also called oestrogen, oestradiol, is an estrogen steroid hormone and the major female sex hormone. It is involved in the regulation of female reproductive cycles such as estrous and menstrual cycles .

2002年1月31日 · Estrogens have widespread biologic actions, and there are naturally occurring phytoestrogens that mimic some of the actions of endogenously produced estrogens. In this review, we will focus on new...
Estrogen: A master regulator of bioenergetic systems in the brain …
Estrogen is a systems-level signaling molecule that regulates and coordinates multiple functions across organs, cells and genes. To achieve this integration, estrogen utilizes a repertoire of receptors and signaling pathways to activate and regulate molecular and genomic responses required for survival at the cellular, organismic and ultimately ...

2024年11月6日 · estrogen, any of a group of hormones that primarily influence the female reproductive tract in its development, maturation, and function. There are three major hormones—estradiol, estrone, and estriol—among the estrogens, and estradiol is the predominant one.
The structural biology of oestrogen metabolism - ScienceDirect
2013年9月1日 · Many enzymes catalyse reactions that have an oestrogen as a substrate and/or a product. The reactions catalysed include aromatisation, oxidation, reduction, sulfonation, desulfonation, hydroxylation and methoxylation. The enzymes that catalyse these reactions must all recognise and bind oestrogen but, despite this, they have diverse structures.
