Hypothalamic pregnenolone mediates recognition memory in the context of metabolic disorders

Maria del Carmen Sandi Perez, Ioannis Zalachoras, Sara Ramirez Flores

Obesity and type 2 diabetes are associated with cognitive dysfunction. Because the hypothalamus is implicated in energy balance control and memory disorders, we hypothesized that specific neurons in this brain region are at the interface of metabolism and ...

Structures of ABCG2 under turnover conditions reveal a key step in the drug transport mechanism

Henning Paul-Julius Stahlberg, Dongchun Ni

ABCG2 is a multidrug transporter that affects drug pharmacokinetics and contributes to multidrug resistance of cancer cells. In previously reported structures, the reaction cycle was halted by the absence of substrates or ATP, mutation of catalytic residue ...

Structural basis of drug recognition by the multidrug transporter ABCG2

Henning Paul-Julius Stahlberg, Dongchun Ni

ABCG2 is an ATP-binding cassette (ABC) transporter whose function affects the pharmacokinetics of drugs and contributes to multidrug resistance of cancer cells. While its interaction with the endogenous substrate estrone-3-sulfate (E1S) has been elucidated ...

MondoA regulates gene expression in cholesterol biosynthesis-associated pathways required for zebrafish epiboly

Cédric Gobet, Frédéric Bruno Martin Gachon, Benjamin Dieter Weger, Meltem Weger

The glucose-sensing Mondo pathway regulates expression of metabolic genes in mammals. Here, we characterized its function in the zebrafish and revealed an unexpected role of this pathway in vertebrate embryonic development. We showed that knockdown of mond ...

A high resolution LC-MS targeted method for the concomitant analysis of 11 contraceptive progestins and 4 steroids

Cathrin Brisken, Jonathan Paz Montoya, Marc Moniatte, Fabio De Martino, Marie Shamseddin, Csaba Ferenc László, Alexandre Béguin

In the context of hormonal contraception and hormone replacement therapy (HRT), many women are exposed to exogenous hormones. Current use of hormonal contraception with combined ethinyl estradiol and different progestins bestows a breast cancer relative ri ...

Identifying gene function and module connections by the integration of multispecies expression compendia

Johan Auwerx, Kristina Schoonjans, Stephan Morgenthaler, Hao Li, Maroun Bou Sleiman, Elena Katsyuba, Wen Gao, Daria Rukina, Qingyao Huang, Yang Li, Changmyung Oh, Andrea Komljenovic

The functions of many eukaryotic genes are still poorly understood. Here, we developed and validated a new method, termed GeneBridge, which is based on two linked approaches to impute gene function and bridge genes with biological processes. First, Gene-Mo ...

Increased brain glucocorticoid actions following social defeat in rats facilitates the long-term establishment of social subordination

Maria del Carmen Sandi Perez, Jocelin Grosse, Olivia Zanoletti, Meltem Weger

Social rank is frequently established through aggressive encounters between new conspecifics. Despite increasing evidence suggesting that social rank is critical for the well-being of both humans and animals, knowledge about the factors influencing social ...

Artificial receptors for hydrophobic molecules usually have moderate affinities and limited selectivities. We describe three new classes of high affinity hydrophobic receptors for nonaromatic steroids based on deoxyribonucleotides, obtained through five hi ...

Intestinal steroidogenesis controls PPAR expression in the colon and is impaired during ulcerative colitis

Johan Auwerx

Background and aims Immune tolerance breakdown during UC involves the peroxisome proliferator-activated receptor- (PPAR), a key factor in mucosal homoeostasis and the therapeutic target of 5-aminosalycilates, which expression is impaired during UC. Here we ...

Identification of the Link Between the Hypothalamo-Pituitary Axis and the Testicular Orphan Nuclear Receptor NR0B2 in Adult Male Mice

Kristina Schoonjans

The small heterodimer partner (SHP, nuclear receptor subfamily 0, group B, member 2; NR0B2) is an atypical nuclear receptor known mainly for its role in bile acid homeostasis in the enterohepatic tract. We previously showed that NR0B2 controls testicular f ...
