Inter-individual variation in levels of sex hormones results from differences in genetic, developmental, and environmental factors. We tested a hypothesis that programming of the fetal neuroendocrine axis may predispose some women to produce higher levels of steroid hormones during their menstrual cycles as adults. One hundred forty-five regularly menstruating 24- to 36- year-old women collecte...

We therefore carried out a meta-analysis aiming to examine the associations of lung cancer in women with menstrual and reproductive factors.

Steroid hormone receptor co-factors are abundantly expressed in the uterus in order to modify steroid hormone receptor action, either leading to activation or repression of transcription in the endometrium. However, the role of co-factors in remodelling of the human endometrium has not been established. We therefore endeavoured to evaluate the presence of the co-activator SRC (steroid receptor ...
