Deregulation of Cell Proliferation by Polycyclic Aromatic Hydrocarbons in Human Breast Carcinoma MCF-7 Cells Reflects Both Genotoxic and Nongenotoxic Events

Autor: Alois Kozubík, Jan Vondráček, Bořivoj Vojtěšek, Martina Plíšková, Miroslav Machala

Publikováno v: Toxicological Sciences. 83:246-256

Polycyclic aromatic hydrocarbons (PAHs), such as benzo[a]pyrene (BaP), are carcinogens suggested to be involved in development of human cancer. Several recent studies have reported that PAHs can activate estrogen receptors (ER), either directly or in

Polychlorinated biphenyls (PCBs) are thought to cause numerous adverse health effects, but their impact on estrogen signaling is still not fully understood. In the present study, we used the ER-CALUX bioassay to determine estrogenic/antiestrogenic ac

Effects of silymarin flavonolignans and synthetic silybin derivatives on estrogen and aryl hydrocarbon receptor activation

Autor: Petr Sedmera, Martina Plíšková, Radek Gazak, Miroslav Machala, Daniela Walterová, Jan Vondráček, Vladimir Kren, Vilím Šimánek, Jitka Psotová

Publikováno v: Toxicology. 215(1-2)

Silymarin, a standardized mixture of flavonolignans, or its major constituents could be effective for prevention and treatment of hepatic damage or skin cancer. However, their potential side effects, such as modulation of endocrine functions via the

Induction of aryl hydrocarbon receptor-mediated and estrogen receptor-mediated activities, and modulation of cell proliferation by dinaphthofurans

Autor: Werner Brack, Miroslav Machala, Martina Plíšková, Jan Vondráček, Alois Kozubík, Luděk Bláha, Kateřina Chramostová

Publikováno v: Environmental toxicology and chemistry. 23(9)

A group of heterocyclic aromatic compounds, dinaphthofurans (DNFs), recently have been identified as potentially significant contaminants in freshwater sediments. In the present study, a battery of in vitro assays was used for detection of toxic effe

Publikováno v: Chemical research in toxicology. 17(3)

In the present study, a series of 32 hydroxy- and dihydroxy-polychlorinated biphenyls (OH-PCBs) and PCB-derived quinones were prepared and evaluated for their in vitro potencies to downregulate gap junctional intercellular communication (GJIC) and to
