The Journal of Steroid Biochemistry and Molecular Biology is devoted to new experimental or theoretical developments in areas related to steroids. It publishes original papers as well as general and mini-reviews, proceedings of selected meetings and rapid communications (brief highly-topical articles of particular interest).The journal covers a wide range of topics relating to steroids:- Molecular, cellular, and physiological actions of steroid hormones, steroid anti-hormones and their analogs via regulation of gene expression or other mechanisms. Structure, function, regulation, and cell biology of receptors of the steroid-thyroid-retinoid superfamily. Cross-talk between steroids, steroid receptors and other signal transduction pathways. Steroids and cell proliferation, regulation of cell cycle genes. Steroid transport. Steroids and cancer: functional relationships in normal and neoplastic tissues between steroid hormones and cytokines, growth factors, growth inhibitors, and oncogenes. Steroids and cancer prevention. Biosynthesis, secretion, and metabolism of steroids and of biologically-related compounds, and their regulation by peptide hormones, prostaglandins and other substances. Molecular aspects of enzymes involved in steroidogenesis. Novel therapeutic applications of new steroid agonists or antagonists. Steroids and neuroendocrinology or neuroimmunology.
