Innovative Techniques and Strategies for a Reliable High-Throughput Genotoxicity Assessment

Pauline Franz

Damage to DNA is a central mechanism to the initiation of carcinogenesis. As a consequence, precise DNA damage detection is essential for an effective risk assessment of xenobiotics and constitutes a powerful tool for human biomonitoring and early stage ca ...

Membrane expression of the estrogen receptor ER alpha is required for intercellular communications in the mammary epithelium

Cathrin Brisken, Stéphanie Cagnet

17 beta-Estradiol induces the postnatal development of mammary gland and influences breast carcinogenesis by binding to the estrogen receptor ER alpha. ER alpha acts as a transcription factor but also elicits rapid signaling through a fraction of ER alpha ...

Hexachlorobenzene exerts genotoxic effects in a humpback whale cell line under stable exposure conditions

Kristin Schirmer, Jenny Maner

Humpback whales, like other polar wildlife, accumulate persistent organic pollutants. In Southern hemisphere populations, hexachlorobenzene (HCB) dominates the contaminant profiles. HCB is linked to a variety of health effects and is classified as a group ...
