Differential Effects of Hormones on Cellular Metabolism in Keratoconus
www.nature.com/scientificreports OPEN Differential Effects of Hormones on Cellular Metabolism in Keratoconus In Vitro Received: 27 October 2016 Tina B McKay1, Jesper Hjortdal2, Henrik Sejersen2 & Dimitrios Karamichos1,3 Accepted: 18 January 2017 Keratoconus (KC) is a corneal thinning disease with an onset commonly immediately post-puberty Published: 17 February 2017 and stabilization by 40 to 50 years of age. The role of hormones in regulating corneal tissue structure in homeostatic and pathological conditions is unknown. Our group recently linked altered hormone levels to KC. Our current study sought to investigate and delineate the effects of exogenous hormones, such as androgen, luteotropin, and estrogen, on corneal stroma bioenergetics. We utilized our established 3D in vitro model to characterize the effects of DHEA, prolactin, 17β-estradiol on insulin- growth factor-1 and -2 (IGF-1, -2) signaling and metabolic function in primary corneal fibroblasts from healthy controls (HCFs) and KC patients (HKCs). Our data showed that exogenous DHEA significantly downregulated IGF-1 and its receptor in both HCFs and HKCs with HKCs showing consistently lower basal pentose phosphate flux. Prolactin caused no significant change in IGF-1 levels and an increase in IGF-2 in HKCs correlating with an increase in ATP and NADH levels. 17β-estradiol led to a significant upregulation in pentose phosphate flux and glycolytic intermediates in HCFs. Our results identified hormone-specific responses regulated in HKCs compared to HCFs revealing a novel role for hormones on bioenergetics in KC. Sex hormones play a functional role in regulating growth and reproduction, systemic metabolism, and cellular differentiation and functionality1–3. -

The predominant biological effects of E2 are mediated through two distinct intracellular receptors, ERα and ERβ, each encoded by unique genes possessing the functional domain characteristics of the steroid/thyroid hormone superfamily of nuclear receptors1. ERα is the predominant form expressed in the breast, uterus, cervix, and vagina. ERβ exhibits a more limited pattern and is primarily expressed in the ovary, prostate, testis, spleen, lung, hypothalamus, and thymus2. Estradiol also influences bone growth, brain development and maturation, and food intake3, and it is also critical in maintaining organ functions during severe trauma4,5. -
A Guide to Feminizing Hormones – Estrogen
1 | Feminizing Hormones A Guide to Feminizing Hormones Hormone therapy is an option that can help transgender and gender-diverse people feel more comfortable in their bodies. Like other medical treatments, there are benefits and risks. Knowing what to expect will help us work together to maximize the benefits and minimize the risks. What are hormones? Hormones are chemical messengers that tell the body’s cells how to function, when to grow, when to divide, and when to die. They regulate many functions, including growth, sex drive, hunger, thirst, digestion, metabolism, fat burning & storage, blood sugar, cholesterol levels, and reproduction. What are sex hormones? Sex hormones regulate the development of sex characteristics, including the sex organs such as genitals and ovaries/testicles. Sex hormones also affect the secondary sex characteristics that typically develop at puberty, like facial and body hair, bone growth, breast growth, and voice changes. There are three categories of sex hormones in the body: • Androgens: testosterone, dehydroepiandrosterone (DHEA), dihydrotestosterone (DHT) • Estrogens: estradiol, estriol, estrone • Progestin: progesterone Generally, “males” tend to have higher androgen levels, and “females” tend to have higher levels of estrogens and progestogens. What is hormone therapy? Hormone therapy is taking medicine to change the levels of sex hormones in your body. Changing these levels will affect your hair growth, voice pitch, fat distribution, muscle mass, and other features associated with sex and gender. Feminizing hormone therapy can help make the body look and feel less “masculine” and more “feminine" — making your body more closely match your identity. What medicines are involved? There are different kinds of medicines used to change the levels of sex hormones in your body. -

Hormonal Treatment Strategies Tailored to Non-Binary Transgender Individuals
Journal of Clinical Medicine Review Hormonal Treatment Strategies Tailored to Non-Binary Transgender Individuals Carlotta Cocchetti 1, Jiska Ristori 1, Alessia Romani 1, Mario Maggi 2 and Alessandra Daphne Fisher 1,* 1 Andrology, Women’s Endocrinology and Gender Incongruence Unit, Florence University Hospital, 50139 Florence, Italy; [email protected] (C.C); jiska.ristori@unifi.it (J.R.); [email protected] (A.R.) 2 Department of Experimental, Clinical and Biomedical Sciences, Careggi University Hospital, 50139 Florence, Italy; [email protected]fi.it * Correspondence: fi[email protected] Received: 16 April 2020; Accepted: 18 May 2020; Published: 26 May 2020 Abstract: Introduction: To date no standardized hormonal treatment protocols for non-binary transgender individuals have been described in the literature and there is a lack of data regarding their efficacy and safety. Objectives: To suggest possible treatment strategies for non-binary transgender individuals with non-standardized requests and to emphasize the importance of a personalized clinical approach. Methods: A narrative review of pertinent literature on gender-affirming hormonal treatment in transgender persons was performed using PubMed. Results: New hormonal treatment regimens outside those reported in current guidelines should be considered for non-binary transgender individuals, in order to improve psychological well-being and quality of life. In the present review we suggested the use of hormonal and non-hormonal compounds, which—based on their mechanism of action—could be used in these cases depending on clients’ requests. Conclusion: Requests for an individualized hormonal treatment in non-binary transgender individuals represent a future challenge for professionals managing transgender health care. For each case, clinicians should balance the benefits and risks of a personalized non-standardized treatment, actively involving the person in decisions regarding hormonal treatment. -
Degradation of Doping-Relevant Steroids by Rh. Erythropolis
In: W Schänzer, H Geyer, A Gotzmann, U Mareck (eds.) Recent Advances In Doping Analysis (15). Sport und Buch Strauß - Köln 2007 J. Grosse1), C. Rautenberg1), L. Wassill2), D. Ganghofner2), D. Thieme3) Degradation of doping-relevant Steroids by Rh. Erythropolis 1) Institute of Doping Analysis and Sports Biochemistry, D-01731 Kreischa, Germany 2) Amplex Diagnostics GmbH, D-80337 Munich, Germany 3) Institute of Legal Medicine, D-80337 Munich, Germany Introduction Former studies have shown that steroids are potential substrates for microorganisms [1]. As an example, the degradation of testosterone induced by Rhodococcus erythropolis was observed. The formation of 4-androstene-3,17-dione, 1,4-androstadiene-3,17-dione (boldione) and 1,4-androstadiene-17β-hydroxy-3-one (boldenone) was confirmed [2]. Consequently a potential endogenous origin of boldenone and its metabolites has to be taken into consideration for the evaluation of routine doping control samples revealing the presence of these substances at low concentration level [3, 4]. This work presents results obtained from further studies related to the microbial conversion of steroid substrates being relevant in doping analysis. For this purpose incubation by Rh. erythropolis was applied to examine the influence of structural variations (A/B-ring structure, substitution at position 17, conjugation) on the initial steps of the degradation pathway. Experimental Rh. erythropolis culture grown on agar plate “Mueller-Hinton” was utilised. Altogether 16 substrates (see table 1) were examined in this study. The experiments were carried out in a blank urine of a male infant spiked with 1 µg/mL of the selected substrate. Two aliquots of each sample were prepared, one control without addition and one „active“ sample with addition of bacteria solution, and incubated at 30°C for 24 hours. -
