Development of Resistance to Sorafenib, a Multikinase Inhibitor, in Hepatocellular Carcinoma is Mediated by SIRT

Garten Antje , Grohmann Theresa , Barnikol-Oettler Anja , Kluckova Katharina , Lavery Gareth , Kiess Wieland , Penke Melanie

Background/aim: Sorafenib® is a multi-kinase inhibitor and one of the few systemic treatment options for patients with advanced hepatocellular carcinomas (HCCs). Resistance to Sorafenib® develops frequently and could be mediated by the NAD dependent deacetylase sirtuin (SIRT) 1, a master regulator of cellular energy metabolism and stress responses. We aimed to find out if Sorafenib® treatment depends on changes in cellular NAD le...

Minipuberty - Looking into the future

Main Katharina M.

The transient activation of the hypothalamus-pituitary-gonadal (HPG) axis shortly after birth has been described as early as in the 70ies. This discovery has since been applied clinically as a ‘window of opportunity’ for diagnostic evaluation of patients suspected of endocrine disorders and differences of sex development. With the advent of increasingly more sensitive and specific analytical methods for peptide and steroid hormones produced in the pituitary, gonads...

The Interaction Between Human and Technology in the Treatment of Diabetes

Barnard Katharine

Background: Research has demonstrated that technologies to support diabetes self-management for people living with diabetes can have positive effects on medical and quality of life outcomes. It also shows that there may be an additional burden of wearing and using these technologies. Both diabetes and its treatment can have significant deleterious effect on quality of life, thus it is crucial that the interaction between the technology and the user offers maximum benefit with ...

Male Fertility Genes Located in Y-Chromosomal Regions Display Differential mRNA Profiles in Response to GnRH Treatment of Cryptorchidism-Dependent Infertility

Hadziselimovic Faruk , Gegenschatz-Schmid Katharina , Verkauskas Gilvidas , Stadler Michael

Background: Undescended testes in patients with defective mini-puberty contain germ cells that fail to differentiate normally into Ad spermatogonia and ultimately leads to infertility. Six months treatment with the gonadotropin-releasing hormone GnRH increases luteinizing hormone and testosterone secretion and rescues fertility in the majority of pathological cryptorchid testes. Several Y chromosomal genes in the male-specific Y region (MSY) are essential for spermatogenesis, ...

Novel Gata6-Mutation in a Boy with Neonatal Diabetes and Diaphragmatic Hernia

Gaisl Odile Christin , Konrad Daniel , Steindl Katharina , Lang-Muritano Mariarosaria

Background: Onset of diabetes in the neonatal period with additional malformations e.g. congenital heart defects should always be suspicious for an underlying genetic disorder. For example, GATA6-mutations were identified in children with congenital heart defects and neonatal diabetes. The latter may be due to pancreas agenesis. Herein we present a novel GATA6-mutation in a boy with transient neonatal diabetes, diaphragmatic hernia, congenital heart defect and early onset scol...

Genetic Variation of AMH Signaling Affects AMH and Inhibin B Levels in Healthy Peripubertal Girls

Hagen Casper P , Almstrup Kristian , Main Katharina M , Juul Anders

Background: Anti-Müllerian hormone (AMH) is produced by small growing ovarian follicles. It inhibits both FSH induced maturation of follicles as well as aromatase activity. Genetic variation of AMH signalling is associated with age at menopause and circulating oestradiol levels, i.e. AMH rs10407022 T>G (intragenic) and AMHR2 rs11170547 C>T (putative enhancer).Objective and hypotheses: This present study aims to investigate ...

Variation of Environmental Chemicals Measured in Serum During Pregnancy

Assens Maria , Frederiksen Hanne , Juul Anders , Main Katharina

Background: Significant changes in metabolism and water equilibrium are registered during pregnancy. However, very limited previous investigations have been carried out on variations of exposure levels and metabolism of non-persistent environmental chemicals during pregnancy.Objective and hypotheses: The objective of this longitudinal study is to describe variation in exposure of pregnant women to environmental chemicals. We hypothesise that variation in...

Sleeptime-excreted total urinary luteinizing hormone concentrations reveal that the onset of central puberty occurs at around the same time in boys and girls: a longitudinal study

Demir And , Hero Matti , Juul Anders , M. Main Katharina

Objectives: We designed a longitudinal study to investigate the association between central pubertal activation with age at the appearance of clinical signs of puberty. We, therefore, assessed nocturnal gonadotropin secretion which can be detected in the form of total luteinizing hormone (LH) immunoreactivity in the daytime- and sleeptime-excreted urine.Methods: Thirty healthy volunteers (17 boys and 13 girls, aged 3.4&n...

Sowithayasakul Panjarat , Buschmann Leona Katharin , Boekhoff Svenja , Muller Hermann L. ,

Background: Hypothalamic obesity caused by childhood–onset craniopharyngioma results in long–term cardiovascular morbidity. Knowledge about clinical markers and risk factors for cardiovascular morbidity is scarce.Patients and Methods: A cross–sectional study on transthoracic echocardiographic parameters was performed to determine the associations with clinical and anthropometric parameters in 36 craniopharyngioma patients....

Muscle function in XLH - Two year prospective observation of paediatric patients before and after treatment initiation with burosumab

Rehberg Mirko , Heistermann Johanna , Neuburg Lisa , Schönau Eckhard , Hoyer-Kuhn Heike-Katharina , Semler Oliver

X-linked hypophosphatemia (XLH, MIM 307800) is a rare hereditary disorder of bone metabolism characterized by growth impairment, leading to bone deformities and short stature and beside others to muscle function deficits. XLH is caused by defect of endopeptidase PHEX leading to high levels of FGF-23 and thereby renal phosphate wasting. While conventional treatment includes substitution of phosphate and 1-25 OH-Vitamin D, now a treatment with a FGF-23 antibody (burosumab) is av...
