It has been suggested that administration of the omega-3 polyunsaturated fatty acids (ω-3 PUFAs), including docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), can alter the toxicity and/or activity of several anticancer drugs in in vitro and in vivo studies. Here, we investigated the

Omega 3 fatty acids chemosensitize multidrug resistant colon cancer cells by down-regulating cholesterol synthesis and altering detergent resistant membranes composition.

BACKGROUND The activity of P-glycoprotein (Pgp) and multidrug resistance related protein 1 (MRP1), two membrane transporters involved in multidrug resistance of colon cancer, is increased by high amounts of cholesterol in plasma membrane and detergent resistant membranes (DRMs). It has never been

Omega-3 fatty acid inhibition of prostate cancer progression to hormone independence is associated with suppression of mTOR signaling and androgen receptor expression.

Currently, progression of prostate cancer to androgen independence remains the primary obstacle to improved survival. In order to improve overall survival, novel treatment strategies that are based upon specific molecular mechanisms that prolong the androgen-dependent state and that are useful for

The omega-3 fatty acid, eicosapentaenoic acid (EPA), prevents the damaging effects of tumour necrosis factor (TNF)-alpha during murine skeletal muscle cell differentiation.

BACKGROUND Eicosapentaenoic acid (EPA) is a omega-3 polyunsaturated fatty acid with anti-inflammatory and anti-cachetic properties that may have potential benefits with regards to skeletal muscle atrophy conditions where inflammation is present. It is also reported that pathologic levels of the

The aim of the present study was to examine the association between daily omega-3 fatty acid intake and depression in Japanese cancer patients. Omega-3 fatty acid intake in 771 patients with newly diagnosed primary lung cancer was evaluated using a food-frequency questionnaire, and the prevalence of

Levels of omega-3 fatty acid in serum phospholipids and depression in patients with lung cancer.

Previous studies suggested that omega-3 fatty acids (FAs) have therapeutic effects against depression, but there is no evidence in the oncological setting. Our preliminary study reported the association between lower omega-3 FA intake and occurrence of depression in lung cancer patients. To explore

Omega-3 fatty acid modification of membrane structure and function. I. Dietary manipulation of tumor cell susceptibility to cell- and complement-mediated lysis.

Omega-3 fatty acids, abundant in fish oil, are reported to alter membrane properties when incorporated into membrane phospholipids. We report that dietary omega-3 fatty acids, incorporated into tumor cell membranes, alter tumor recognition and cytolysis by the immune system. Mice were fed diets rich

Omega-3 N-acylethanolamines are endogenously synthesised from omega-3 fatty acids in different human prostate and breast cancer cell lines.

Omega-3 (n-3) fatty acids inhibit breast and prostate cancer cell growth. We previously showed that N-acylethanolamine derivatives of n-3 (n-3-NAE) are endocannabinoids, which regulate cancer cell proliferation. These n-3-NAE are synthesised in certain cells/tissues, after supplementing with fatty

The aim of this study was to evaluate the impact that 6-O-(3″, 4″-di-O-trans-cinnamoyl)-α- l-rhamnopyranosylcatalpol (Dicinn) and verbascoside (Verb), two compounds simultaneously reported in Verbascum ovalifolium, have on tumor cell viability, apoptosis, cell cycle kinetics, and intracellular

There is both epidemiologic and experimental evidence that the long-chain omega-3 fatty acids (FAs), which occur at high levels in some fish oils, exert protective effects against some common cancers, notably those of breast, colon, and, perhaps, prostate. Multiple mechanisms are involved in this

Omega-3 (omega-3) fatty acids have been clinically and experimentally associated with the amelioration of chronic and acute inflammation; however, the mechanisms for these observations have not been well defined. During the past decade, laboratories of nutrition and inflammation have demonstrated

Purpose: Patients with digestive system cancer frequently over-express inflammatory cytokines after surgical operations or chemotherapy. Omega-3 fatty acids are key nutrients with numerous beneficial anti-inflammatory effects in cancer patients. The anti-inflammatory effect of supplementation

Hemangiomas of infancy are benign vascular tumors frequently encountered in pediatrics. Medical treatment (corticosteroids, interferon, chemotherapy, embolization and radiation) in high-risk hemangioma cases could greatly benefit from the addition of new and safer therapies. The rapid growth of

BACKGROUND Proinflammatory cytokines may contribute to clinical complications in heart transplant (HTx) recipients. Previous studies have shown immunomodulating effects of omega-3 fatty acids, but the results are somewhat conflicting. In this study, we examined plasma levels of tumor necrosis factor

Modulating Survivin as a Radioresistant Factor, Caspase-3, and Apoptosis by Omega-3 Docosahexaenoic Acid Sensitizes Mutant-p53 Colorectal Cancer Cells to γ-Irradiation.

Mutant-p53 colorectal cancer (CRC) cells are often resistant to radiotherapy. Loss of suppressor activity of wt-p53 on survivin is responsible for the enhanced expression of survivin as a radioresistant factor in tumor cells. Yet, no survivin-modulating drug has been approved for clinical
