Lipoxygenase-mediated Oxidation of Polyunsaturated N-Acylethanolamines in Arabidopsis (open access)

Lipoxygenase-mediated Oxidation of Polyunsaturated N-Acylethanolamines in Arabidopsis

Article hypothesizing that lipoxygenase (LOX) participated in the metabolism of PU-NAEs through the formation of NAE-oxylipins. The data suggests that Arabidopsis LOXs indeed compete with FAAH to metabolize PU-NAEs during seedling establishment. Identification of endogenous amide-conjugated oxylipins suggests potential significance of these metabolites in vivo, and FAAH mutants may offer opportunities to address this in the future.

Visualization of Lipid Droplet Composition by Direct Organelle Mass Spectrometry (open access)

Visualization of Lipid Droplet Composition by Direct Organelle Mass Spectrometry

Article reporting an approach that combines the visualization of individual lipid droplets (LDs), microphase extraction of lipid components from droplets, and the direct identification of lipid composition by nanospray mass spectrometry, even to the level of a single LD. The triacylglycerol (TAG) composition of LDs from several plant sources (mature cotton (Gossypium hirsutum) embryos, roots of cotton seedlings, and Arabidopsis thaliana seeds and leaves) were examined by direct organelle mass spectrometry and revealed the heterogeneity of LDs derived from different plant tissue sources.

Pulmonary compliance and lung volume varies with ecomorphology in anuran amphibians: implications for ventilatory-assisted lymph flux (open access)

Pulmonary compliance and lung volume varies with ecomorphology in anuran amphibians: implications for ventilatory-assisted lymph flux

Structural Consideration in Designing Organotin Polyethers to Arrest the Growth of Breast Cancer Cells In Vitro (open access)

Structural Consideration in Designing Organotin Polyethers to Arrest the Growth of Breast Cancer Cells In Vitro

The article looks at antitumor activity using a matched pair of cell lines MDA-MB-231 cells that are estrogen-independent, estrogen receptor negative and MCF-7 cells, a cell line that is estrogen receptor (ER) positive. Those polyethers that contained a O-phenyl unit were able to significantly inhibit the non-estrogen sensitive cell line but were much less effective against the estrogen sensitive cell line; that is, the human breast cancer cell line MDA-MB-231 showed better test results for polymers derived from diols containing the O-phenyl moiety than the breast cancer cell line MCF-7, a well-characterized estrogen receptor positive control cell line.

Antiviral Activity of Metal-Containing Polymers—Organotin and Cisplatin-Like Polymers (open access)

Antiviral Activity of Metal-Containing Polymers—Organotin and Cisplatin-Like Polymers

This article examines the use of metal-containing polymers as a novel class of antivirals. Polymers containing platinum and to a lesser extent tin, have repeatedly demonstrated antitumor activity in vitro and in vivo against a variety of cell and tumor types. The mechanisms responsible for the antitumor activity include inducing a delay in cell proliferation and sister chromatid exchanges blocking tumor growth.
