Diatoms are an important class of unicellular algae that produce bioactive secondary metabolites with cytotoxic activity collectively termed oxylipins, including polyunsaturated aldehydes (PUAs), hydroxyacids (HEPEs), oxo-acids and epoxyalcohols. Previous results showed that at higher concentrations, the PUA decadienal induced apoptosis on copepods and sea urchin embryos via caspase-3 activatio...
Oxylipins or oxidized fatty acids are a group of molecules found to play a role in signaling in many different cell types. These fatty acid derivatives have ancient evolutionary origins as signaling molecules and are ideal candidates for inter-kingdom communication. This review discusses examples of the ability of organisms from different kingdoms to "listen" and respond to oxylipin signals dur...
This article is available online at http://www.jlr.org An impact on arterial stiffness and compliance, associated with reduced blood pressure (1–4), is thought to be a significant contributor to the lower CVD risk associated with increased long chain n-3 PUFA (LC n-3 PUFA; EPA plus DHA) intake and status (4–6). In randomized controlled trials (RCTs) conducted to date, vascular function is typic...
Neurodegenerative disease are characterized by the progressive loss of neurons from specific origins of the CNS .Alzheimer disease (AD) is a neurodegenerative disorder which affect brain regains that control memory and ability to learn. It is estimated that 27 million people are affected word wide and this number is expected to triple by 2050 due to increase of the population life expectancy. A...
BACKGROUND Asthma is a respiratory tract disorder characterized by airway hyper-reactivity and chronic inflammation. Allergic asthma is associated with the production of allergen-specific IgE and expansion of allergen-specific T-cell populations. Progression of allergic inflammation is driven by T-helper type 2 (Th2) mediators and is associated with alterations in the levels of lipid mediators....
Traditionally, diatoms have been regarded as providing the bulk of the food that sustains the marine food chain and important fisheries. However, this view was challenged almost two decades ago on the basis of laboratory and field studies showing that when copepods, the principal predators of diatoms, feed on certain diatom diets, they produce abnormal eggs that either fail to develop to hatchi...
