DNA methylation sites in early adulthood characterised by pubertal timing and development: a twin study

Background Puberty is a highly heritable and variable trait, with environmental factors having a role in its eventual timing and development. Early and late pubertal onset are both associated with various diseases developing later in life, and epigenetic c ...

Association of a Polygenic Risk Score With Osteoporosis in People Living With HIV: The Swiss HIV Cohort Study

Jacques Fellay, Christian Axel Wandall Thorball

An individual polygenic risk score was associated with osteoporosis in people living with HIV. The genetic effect was robust, as it persisted after multivariable adjustment for established traditional and HIV-related osteoporosis risk factors, including te ...

Programming effects of peripubertal stress on spatial learning

Maria del Carmen Sandi Perez, Stamatina Tzanoulinou, Cristina Marquez Vega

Exposure to adversity during early life can have profound influences on brain function and behavior later in life. The peripubertal period is emerging as an important time-window of susceptibility to stress, with substantial evidence documenting long-term ...

Progestins used for hormonal contraception in Switzerland: study of their effects on the breast epithelium

Marie Shamseddin

Breast cancer is the most commonly diagnosed cancer and the most common cause of cancer death among women. Hormones have been shown to have a key role in breast development and carcinogenesis. Repeated activation of progesterone receptor (PR) signaling as ...

Bile acid-FXR alpha pathways regulate male sexual maturation in mice

Kristina Schoonjans

The bile acid receptor Farnesol-X-Receptor alpha (FRX alpha) is a member of the nuclear receptor superfamily. FRX alpha is expressed in the interstitial compartment of the adult testes, which contain the Leydig cells. In adult, short term treatment (12 hou ...

Implication of individual differences in glucocorticoid responsiveness to stress in the development of psychopathology-like behaviour and underlying neurobiology

Sophie Elizabeth Walker

The period around puberty is a critical window in development. It is a time of neuroendocrine and neuroanatomical lability, rendering individuals highly sensitive to stress. Indeed, early adversity increases risk for psychopathology. The mechanisms via whi ...

Protein Prenylation Constitutes an Endogenous Brake on Axonal Growth

Suboptimal axonal regeneration contributes to the consequences of nervous system trauma and neurodegenerative disease, but the intrinsic mechanisms that regulate axon growth remain unclear. We screened 50,400 small molecules for their ability to promote ax ...

Early life exposure to PCB126 results in delayed mortality and growth impairment in the zebrafish larvae

Kristin Schirmer

The occurrence of chronic or delayed toxicity resulting from the exposure to sublethal chemical concentrations is an increasing concern in environmental risk assessment. The Fish Embryo Toxicity (FET) test with zebrafish provides a reliable prediction of a ...

An Ex vivo Model to Study Hormone Action in the Human Breast

Cathrin Brisken, Georgios Sflomos

The study of hormone action in the human breast has been hampered by lack of adequate model systems. Upon in vitro culture, primary mammary epithelial cells tend to lose hormone receptor expression. Widely used hormone receptor positive breast cancer cell ...

Fluence plays a critical role on the subsequent distribution of chemotherapy and tumor growth delay in murine mesothelioma xenografts pre-treated by photodynamic therapy

Georges Wagnières, Jean Yannis Perentes

Background: The pre-conditioning of tumor vessels by low-dose photodynamic therapy (L-PDT) was shown to enhance the distribution of chemotherapy in different tumor types. However, how light dose affects drug distribution and tumor response is unknown. Here ...
