Genotoxic effects of oestrogens and nano-NSAIDs: Genotoxic effects of oestrogens in vivo and nano- and bulk forms of NSAIDs on blood samples from prostate cancer patients
… effects of five intra-peritoneal administered oestrogens (17β- oestradiol, daidzein, diethylstilboestrol, genistein, and equol), were examined. Male hooded- Lister rats were used to examine to what extent DNA damage occurred. The alkaline Comet assay was the chosen method used to assess …

Clinical and metabolic effects of the menopause and the role of replacement oestrogen therapy.
… supportive) therapy. 3. The ability of exogenous oestrogens to produce a feeling of well-being in postmenopausal females is statistically substantiated. 4. The parabasal cell is shown to be the best cytologic index of the oestrogenic status of the postmenopausal female. Claims for an increase of …

The Role of Androgen Receptor Signalling in Endocrine Resistant Breast Cancer
… sensitive and develop through the action of oestrogens, facilitated through the transcription factor Oestrogen Receptor alpha (ERα). Treatment for these patients usually involves endocrine therapies (Aromatase Inhibitors and antioestrogens), which are successful in many patients, but therapy …

Biochemistry of ovarian cells in vitro
… granulosa cells in tissue culture to synthesize oestrogens was examined. The cells had an active "\Shydroxylase enzyme system which aromatized both exogenous androstenedione and testosterone to oestradiol. In the absence of exogenous androgens, however, the cells failed to synthesize oestrogens …

Biochemical studies on Oestradiol 17β in human mammary tumours and chemically induced rat mammary tumours
The involvement of oestrogens and related factors in the development and behaviour of mammary cancer is reviewed. The currently accepted view is that the selective retention of administered tritium labelled oestradiol 170 by certain mammary tumours is due to the possession of specific oestradiol …

Phosphorylation of ERα and HIF-1α in breast cancer with focus on tamoxifen response and links to kinase activation
Anti-oestrogens are commonly used in adjuvant breast cancer treatment and for a long time tamoxifen has been the main endocrine treatment. Patients who are eligibly for endocrine treatment are selected by the tumour-specific expression of oestrogen receptor (ER) and approximately 70 % of all breast …

The Influence of Ovarian Sex Steroids on Insulin Receptor Status in Mice
… observations support the hypothesis that natural oestrogens and progestogens, at least in the long-term, act on peripheral insulin target tissues to increase the action of insulin.
