Palmitoleic acid (PLOA) markedly prolonged the survival time of mice bearing Ehrlich ascites tumor at doses of 37.5-150 mg/kg/day X 10, but the antitumor activity of oleic acid (OA) was weaker than that of PLOA. The total lipid and phospholipid contents in the tumor cells treated with PLOA were

Yoshida sarcoma cells were incubated with each of 4 different saturated and 17 different unsaturated fatty acid methyl and ethyl esters in order to modify the fatty acid composition of the cell membrane, and a possible correlation between the lipid fluidity of the cell membrane and the metastatic

Palmitoleic acid reduces the inflammation in LPS-stimulated macrophages by inhibition of NFκB, independently of PPARs.

Palmitoleic acid (PM, 16:1n-7) has anti-inflammatory properties that could be linked to higher expression of PPARα, an inhibitor of NFκB. Macrophages play a major role in the pathogenesis of chronic inflammation, however, the effects of PM on macrophages are underexplored. Thus, we aimed to

Fatty acids (FAs) may affect endothelial cell (EC) function, influencing atherogenesis and inflammatory processes. Palmitoleic acid (POA) has been described as an anti-inflammatory FA. However, its effects on ECs are underexplored. This study compares the effects of POA with those of palmitic acid

Previous studies have shown that metabolomics can be a useful tool to better understand the mechanisms of carcinogenesis; however, alterations in biochemical pathways that lead to bladder cancer (BC) development have hitherto not been fully investigated. In this study, gas chromatography-mass

Fatty acid levels in plasma phospholipids were related to food intake over the previous year as estimated by semiquantitative food frequency questionnaires compiled by 280 men and 246 women from the EPIC centers of Varese, Turin, Florence and Ragusa (Italy). Fatty acid content was determined by gas

BACKGROUND Fatty acid (FA) composition in serum has been associated with C-reactive protein (CRP), but associations with other markers of inflammation and endothelial function, e.g. adhesion molecules are unknown. We recently suggested a possible role of the lipogenic enzyme stearoyl coenzymeA

Non-alcoholic fatty liver disease (NAFLD) as a global health problem has clinical manifestations ranging from simple non-alcoholic fatty liver (NAFL) to non-alcoholic steatohepatitis (NASH), cirrhosis, and cancer. The role of different types of fatty acids in driving the early progression of NAFL to

Epidemiological and laboratory animal model studies have provided evidence that the effect of dietary fat on colon tumorigenesis depends on the amount of fat and its composition. Because of the importance of the composition of dietary fat and of tissue membrane fatty acid composition in tumor

We conducted a first pilot study on healthy women living in two countries with different dietary habits, Granada in the south of Spain and Malmö in the south of Sweden, in order to compare their levels of plasma phospholipid fatty acids, and to examine the relationship between the differences in

BACKGROUND Adipocyte fatty acid binding protein (A-FABP) present in macrophages has been implicated in the integration of lipid metabolism and inflammatory response, contributing to development of insulin resistance and atherosclerosis. OBJECTIVE This study was conducted to test the hypothesis that

Wnt proteins regulate a large number of processes including cellular growth, differentiation and tissue homeostasis through the highly conserved Wnt signaling pathway in metazoans. Porcupine (PORCN) is an endoplasmic reticulum (ER)-resident integral membrane enzyme that catalyzes posttranslational

Combined treatment of anticancer drugs and small interfering RNAs (siRNAs) have emerged as a new modality of anticancer therapy. Here, we describe a co-delivery system of anticancer drugs and siRNA in which anticancer drug-derived lipids form cationic nanoparticles for siRNA complexation. The

Aberrant activation of Wnt/β-catenin signaling occurs frequently in cancer. However, therapeutic targeting of this pathway is complicated by the role of Wnt in stem cell maintenance and tissue homeostasis. Here, we evaluated antibodies blocking 6 of the 10 human Wnt/Frizzled (FZD) receptors as
