Sulfated steroid hormones, such as dehydroepiandrosterone sulfate or estrone-3-sulfate, have long been regarded as inactive metabolites as they cannot activate classical steroid receptors. Some of them are present in the blood circulation at quite high concentrations, but generally sulfated steroids exhibit low membrane permeation due to their hydrophilic properties. However, sulfated steroid hormones can actively be imported into specific target cells via uptake carriers, such as the sodium-dependent organic anion transporter SOAT, and, after hydrolysis by the steroid sulfatase (so-called sulfatase pathway), contribute to the overall regulation of steroid responsive organs. To investigate the biological significance of sulfated steroid hormones for reproductive processes in humans and animals, the research group "Sulfated Steroids in Reproduction" was established by the German Research Foundation DFG (FOR1369). Projects of this group deal with transport of sulfated steroids, sulfation of free steroids, desulfation by the steroid sulfatase, effects of sulfated steroids on steroid biosynthesis and membrane receptors as well as MS-based profiling of sulfated steroids in biological samples. This review and concept paper presents key findings from all these projects and provides a broad overview over the current research on sulfated steroid hormones in the field of reproduction.

Objective: The effects of sex hormones remain largely unexplored in pheochromocytomas and paragangliomas (PPGLs) and gastroenteropancreatic neuroendocrine tumors (GEP-NETs).
Methods: We evaluated the effects of estradiol, progesterone, Dehydroepiandrosterone sulfate (DHEAS), and testosterone on human patient-derived PPGL/GEP-NET primary culture cell viability (n = 38/n = 12), performed next-generation sequencing and immunohistochemical hormone receptor analysis in patient-derived PPGL tumor tissues (n = 36).
Results: In PPGLs, estradiol and progesterone (1 µm) demonstrated overall significant antitumor effects with the strongest efficacy in PPGLs with NF1 (cluster 2) pathogenic variants.

Background And Aims: Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease characterised by progressive biliary inflammation and fibrosis, leading to liver cirrhosis and cholangiocarcinoma. GPBAR1 (TGR5) is a G protein-coupled receptor for secondary bile acids. In this study, we have examined the therapeutic potential of BAR501, a selective GPBAR1 agonist in a PSC model.

Aim: There is limited data on the PICU outcomes of children with acute severe asthma (ASA) in South Africa. This study aims to describe the profiles and treatment of all children admitted to our PICU with ASA.
Methods: A retrospective audit of all children admitted with ASA to the PICU at Red Cross War Memorial Children's Hospital between 01 January 2009 and 31 December 2019.

Background: Alcohol intake is associated with a higher risk of estrogen receptor-positive (ER+) breast cancer (BC), presumably through its confirmed ability to increase sex hormone levels. Whether consuming alcohol within the recommended limit of one serving per day increases sex hormone levels among postmenopausal women taking aromatase inhibitors (AI) to inhibit estrogen production remains unknown. Therefore, we compared sex hormone levels following white wine to levels following white grape juice among ER + BC survivors taking AIs.

Background: Sarcopenia, which is associated with many pathways and molecular mechanisms, not only deteriorates the quality of life in old age but is also linked to various diseases. The ratio between cortisol and dehydroepiandrosterone sulfate (DHEAS) was utilized as a candidate method to diagnose sarcopenia. The hormones can fluctuate in concentration throughout the day, so monitoring the ratio between the two hormones is necessary.
