Androgen Receptor Signaling in in vivo models of Estrogen Receptor-positive Breast Cancer and Normal Breast Epithelium

Steroid hormone receptors (HRs) are ligand-activated transcription factors that play a pivotal role in breast development and carcinogenesis. It is well established that estrogen receptor (ER) signaling is a major proliferative driver in estrogen receptor ...

Role of the androgen receptor in the human breast epithelium

Fabio De Martino

Breast cancer is the most common malignancy in women worldwide and understanding the risk factors affecting it is key for prevention. The relative risk of developing breast cancer is related to exposure to both endogenous hormones and exogenous natural and ...

Socioeconomic development predicts a weaker contraceptive effect of breastfeeding

Mathias Lerch

The contraceptive effect of breastfeeding remains essential to controlling fertility in many developing regions of the world. The extent to which this negative effect of breastfeeding on ovarian activity is sensitive to ecological conditions, notably mater ...

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 ...

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 ...

Photoisomerization of Linear and Stacked Isomers of a Charged Styryl Dye: A Tandem Ion Mobility Study

Eduardo Carrascosa Casado

The photoisomerization behavior of styryl 9M, a common dye used in material sciences, is investigated using tandem ion mobility spectrometry (IMS) coupled with laser spectroscopy. Styryl 9M has two alkene linkages, potentially allowing for four geometric i ...

A Drug Release Mechanism Controlled by Hydrophobic/Hydrophilic Balance of the Matrix. Theoretical and Experimental Perspectives

Maria-Alexandra Paun

Controlled drug release is a promising pathway of biomedicine, meant to suppress side effects with the aim of increasing patient's comfort. A route to achieve this goal represents the encapsulation of drugs into matrixes, capable to develop physical forces ...

Sex-specific changes in gene expression in response to estrogen pollution around the onset of sex differentiation in grayling (Salmonidae)

Oliver Michele Selmoni

The synthetic 17 alpha-ethinylestradiol (EE2) is a common estrogenic pollutant that has been suspected to affect the demography of river-dwelling salmonids. One possibility is that exposure to EE2 tips the balance during initial steps of sex differentiatio ...

The role of sensorimotor afferent feedback in mediating functional recovery after spinal cord injury

Kay Alexander Bartholdi

Spinal cord injury (SCI) leads to permanent deficits in sensory and motor function due to the physical disruption of descending and ascending pathways. As a consequence, spinal circuits below the level of lesion remain in an intact, but inactive state. A n ...

Application of Hypervalent Iodine Reagents for Novel Cysteine Labeling

Romain Gaëtan Tessier

Selective functionalization of peptides and proteins has always been a valuable tool for the study and manipulation of biological processes. In this context, cysteines are of particular interest. Their intrinsic high nucleophilicity makes these amino acids ...
