The Potts-Guy model best predicts skin permeability for the tested drugs.
research First-in-human phase 1 study of ETC-159 an oral PORCN inhbitor in patients with advanced solid tumours.
ETC-159 was safe up to 30 mg, but no tumor shrinkage was seen.
research Past and Future Strategies for GPCR Deorphanization
Finding functions for unknown GPCRs is hard but key for making new drugs.
research Evaluation of an eucalyptus oil containing topical drug delivery system for selected steroid hormones
The eucalyptus oil system improved skin delivery of hormones, but safety concerns remain.
research Suppression of Vitamin D Receptor and Induction of Retinoid X Receptor α Expression During Squamous Differentiation of Cultured Keratinocytes
As skin cells mature, vitamin D receptor levels decrease while retinoid X receptor α levels increase.
research Polyamine Oxidase Expression Is Downregulated by 17β-Estradiol via Estrogen Receptor 2 in Human MCF-7 Breast Cancer Cells
17β-estradiol lowers polyamine oxidase levels in breast cancer cells through estrogen receptor 2.
research Neonatal finasteride induces anxiogenic-like profile and deteriorates passive avoidance in adulthood after intrahippocampal neurosteroid administration
Finasteride given to baby rats causes anxiety-like behavior and worsens learning from punishment in adult rats.
research Quantification of the Vitamin D Receptor−Coregulator Interaction
Vitamin D receptor binds similarly to natural and synthetic ligands, affecting gene regulation.
research Evaluation of the rodent Hershberger assay using three reference endocrine disrupters (androgen and antiandrogens)
The assay effectively detects hormonal activity of certain chemicals.
research Progestogen-only pill associates with false-positive aldosterone/renin ratio screening test
The birth control pill with only progestogen can cause a false alarm in a hormone test.
research Testosterone Down-regulates Expression of αVβ3-integrin, E-cadherin and Mucin-1 during Uterine Receptivity Period in Rats
Testosterone reduces key molecules needed for early pregnancy in rats.
research Glucocorticoid Receptor Antagonism Improves Glucose Metabolism in a Mouse Model of Polycystic Ovary Syndrome
Blocking glucocorticoid receptors improves glucose metabolism in a PCOS mouse model.
research Discovery of Nonsteroidal Androgens
Scientists found new nonsteroidal compounds that can act like natural male hormones and might help treat male fertility and hormone issues.
research The Plastic and Functional Changes in Hippocampal Neurons During Pregnancy, Delivery and Postpartum are Reversed by Offspring Deprivation
Pregnancy and nursing increase certain brain activities in rats, but these changes disappear when the babies are taken away.
research The Androgen Receptor and Its Use in Biological Assays: Looking Toward Effect-Based Testing and Its Applications
Scientists have developed a new method to detect steroid abuse in athletes using cell-based tests, which could be the future of anti-doping methods.
research Mechanism of action of bolandiol (19-nortestosterone-3β,17β-diol), a unique anabolic steroid with androgenic, estrogenic, and progestational activities
Bolandiol, a synthetic steroid, builds muscle and bone without greatly affecting sex glands, and works differently from other hormones.
