CCL2 Is a Vascular Permeability Factor Inducing CCR2-Dependent Endothelial Retraction during Lung Metastasis.

Marko Roblek, Darya Protsyuk, Paul F Becker, Cristina Stefanescu, Christian Gorzelanny, Jesus F Glaus Garzon, Lucia Knopfova, Mathias Heikenwalder, Bruno Luckow, Stefan W Schneider, Lubor Borsig,

Increased levels of the chemokine CCL2 in cancer patients are associated with poor prognosis. Experimental evidence suggests that CCL2 correlates with inflammatory monocyte recruitment and induction of vascular activation, but the functionality remains open. Here, we show that endothelial Ccr2 facilitates pulmonary metastasis using an endothelial-specific Ccr2-deficient mouse model (Ccr2ecKO). ... Read more >>

Factors influencing persistent organic pollutant concentrations in the Atlantic white-sided dolphin (Lagenorhynchus acutus).

Karen J S Tuerk, John R Kucklick, Wayne E McFee, Rebecca S Pugh, Paul R Becker,

Assessing the trends of persistent organic pollutants (POPs) in cetaceans is difficult because of age and gender influences on accumulation. Persistent organic pollutants bioaccumulate and are poorly metabolized; hence, concentrations may increase with age in males while females reduce their POP burden through parturition and lactation. Age and gender effects ... Read more >>
