Docosahexaenoic acid impairs the maturation of very low density lipoproteins in rat hepatic cells.

One mechanism of the lipid-lowering effects of the fish oil n-3 fatty acids [e.g., docosahexaenoic acid (DHA)] in cell and animal models is induced hepatic apolipoprotein B100 (apoB) presecretory degradation.

Dietary supplementation with two Lamiaceae herbs-(oregano and sage) modulates innate immunity parameters in Lumbricus terrestris.

Introduction: Lamiaceae herbs have are well known for their immunomodulatory effects, however, the mechanism by which they effect innate immune system is not clearly understood.

Objective: The effect of dietary supplementation with two Lamiaceae herbs (oregano and sage) modulation of on innate immunological parameters was investigated in Lumbricus terrestris.

Materials And Methods: Animals were fed (ad libitum) on herbs supplemented diet [(0.

Cell-free supernatants from probiotic Lactobacillus casei and Lactobacillus rhamnosus GG decrease colon cancer cell invasion in vitro.

Probiotics have been shown to have a preventative role in colorectal carcinogenesis but research concerning their prophylactic potential in the later stages of colorectal cancer, specifically metastasis is limited. This study explored the potential of cell-free supernatants (CFS) from 2 probiotic Lactobacillus sp., Lactobacillus casei and Lactobacillus rhamnosus GG, to inhibit colon cancer cell invasion by influencing matrix metalloproteinase-9 (MMP-9) activity and levels of the tight junction protein zona occludens-1 (ZO-1) in cultured metastatic human colorectal carcinoma cells.

Bioassays of quorum sensing compounds using Agrobacterium tumefaciens and Chromobacterium violaceum.

In most bacteria, a global level of regulation exists involving intercellular communication via the production and response to cell density-dependent signal molecules. This cell density-dependent regulation has been termed quorum sensing (QS). QS is a global regulator, which has been associated with a number of important features in bacteria including virulence regulation and biofilm formation.

Presecretory oxidation, aggregation, and autophagic destruction of apoprotein-B: a pathway for late-stage quality control.

Hepatic secretion of apolipoprotein-B (apoB), the major protein of atherogenic lipoproteins, is regulated through posttranslational degradation. We reported a degradation pathway, post-ER pre secretory proteolysis (PERPP), that is increased by reactive oxygen species (ROS) generated within hepatocytes from dietary polyunsaturated fatty acids (PUFA). We now report the molecular processes by which PUFA-derived ROS regulate PERPP of apoB.
