Ras signaling originates from transient nanoscale compartmentalized regions of the plasma membrane composed of specific proteins and lipids. The highly specific lipid composition of these nanodomains, termed nanoclusters, facilitates effector recruitment and therefore influences signal transduction. This suggests that Ras nanocluster proteolipid composition could represent a novel target for future chemoprevention interventions. There is evidence that consumption of fish oil containing long-chain n-3 polyunsaturated fatty acids (n-3 PUFA) such as eicosapentaenoic acid (EPA, 20:5Δ5,8,11,14,17) and docosahexaenoic acid (DHA, 22:6Δ4,7,10,13,16,19) may reduce colon cancer risk in humans, yet the mechanism underlying this effect is unknown...

Dietary fermentable fiber generates short-chain fatty acids (SCFA), e.g., butyrate, in the colonic lumen which serves as a chemoprotective histone deacetylase inhibitor and/or as an acetylation substrate for histone acetylases. In addition, n-3 polyunsaturated fatty acids (n-3 PUFA) in fish oil can affect the chromatin landscape by acting as ligands for tumor suppressive nuclear receptors. In an effort to gain insight into the global dimension of post-translational modification of histones (including H3K4me3 and H3K9ac) and clarify the chemoprotective impact of dietary bioactive compounds on transcriptional control in a preclinical model of colon cancer, we generated high-resolution genome-wide RNA (RNA-Seq) and "chromatin-state" (H3K4me3-seq and H3K9ac-seq) maps for intestinal (epithelial colonocytes) crypts in rats treated with a colon carcinogen and fed diets containing bioactive (i) fish oil, (ii) fermentable fiber (a rich source of SCFA), (iii) a combination of fish oil plus pectin or (iv) control, devoid of fish oil or pectin...

Cancer is the second leading cause of death with profound socio-economic consequences worldwide. Growing evidence suggests the crucial role of diet on cancer prevention and treatment. In Traditional Persian Medicine (TPM) there is a major focus on contribution of special diet and foods to cancer management. In the present article, the cytotoxic and antitumor activities of several food items including plants and animal products recommended by TPM as anticancer agents are discussed. Strong evidence supports the anticancer effects of beetroot (Beta vulgris) and its major compound betanin, cinnamon and cinnamaldehyde, barley (H...

In Europe, countries following the traditional Mediterranean Diet (MeDi), particularly Southern European countries, have lower prostate cancer (PCa) incidence and mortality compared to other European regions. In the present study, we investigated the association between the MeDi and the relative risk of PCa and tumor aggressiveness in a Spanish population. Among individual score components, it has been found that subjects with PCa were less likely to consume olive oil as the main culinary fat, vegetables, fruits and fish than those without...

Gestational diabetes mellitus (GDM) is a common complication of pregnancy, and it is mostly associated with postpartum diabetes, insulin resistance, and dyslipidemia. Fish oil (omega-3) supplementation has been shown to reduce the risk of different chronic diseases such as cardiovascular disease, type 2 diabetes, and cancers, though the evidence of its impact on gestational diabetes is scarce. Our goal in this study was to determine the effect of fish oil administration on gene expression related to insulin action, blood lipids, and inflammation in women with GDM...

BACKGROUND: Prostate cancer is the most commonly diagnosed cancer in north-American men. Few dietary or lifestyle interventions have been tested to prevent prostate cancer progression. Omega-3 fatty acid supplementation represents a promising intervention for prostate cancer patients. The aim of the study is to evaluate the effects of long-chain omega-3 polyunsaturated fatty acids (LCn3), more precisely eicosapentaenoic acid monoacylglyceride (MAG-EPA) supplementation, on prostate cancer proliferation, inflammation mediators and quality of life among men who will undergo radical prostatectomy...

Intraepithelial lymphocytes (IELs) impart a crucial role in maintaining intestinal homeostasis, yet their role in colon cancer pathogenesis remains unknown. Here, we posited that the modulation of intestinal immune response via dietary interventions might be an implacable strategy in restraining colon carcinoma. In the above context, we studied the effect of differential ratios of fish oil (FO) and corn oil (CO) on the gut immune response in experimentally induced colon cancer. Male Wistar rats were divided into six groups: Group I obtained purified diet while Groups II and III were fed on the diet supplemented with differential ratios of FO and CO i...

Polycyclic aromatic hydrocarbons (PAHs) are a large group of well-known toxicants with carcinogenic potential and other health effects including on the immune system. The high health risks of non-communicable diseases and relevant comorbidities in Africa, particularly in contaminated areas like e-waste and crude oil and gas exploration areas and for high consumers of food commodity groupings which are most critical for PAH exposure, are exacerbated by dietary exposure due to unsafe practices in commonly consumed foods, like those street vended...

REVIEW
Laura VanderSluis, Vera C Mazurak, Sambasivarao Damaraju, Catherine J Field
Epidemiological studies have associated high fish oil consumption with decreased risk of breast cancer (BC). n-3 long chain polyunsaturated fatty acids (n-3 LCPUFA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) found in fish and fish oils exert anti-cancer effects. However, few studies have examined the relative efficacy of EPA and DHA alone and in mixtures on BC subtypes. This was the objective of the present review, as this research is a necessity for the translation of findings to human health and disease...

Dietary eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) may have a role in contributing to the prevention or inhibition of some malignancies. DHA, the most important polyunsaturated fatty acid (PUFA) in fish and thraustochytrid oils, is known for its anticancer activity. However, antigastric cancer activity of thraustochytrid microbial oil is still unclear. In this investigation, 45 thraustochytrid strains were screened for the production of antigastric cancer oil. Cytotoxicity of 12 thraustochytrid oils was assessed by 3-(4,5-dimethythiazol- 2-yl)-2,5-diphenyl tetrazolium bromide (MTT) on gastric cancer AGS cells...

For decades, compounds present in foods and beverages have been implicated in the etiology of human cancers. The World Health Organization (WHO) International Agency for Research on Cancer (IARC) continues to classify such agents regarding their potential carcinogenicity in humans based on new evidence from animal and human studies. Furfuryl alcohol and β-myrcene are potential human carcinogens due to be evaluated. The major source of furfuryl alcohol in foods is thermal processing and ageing of alcoholic beverages, while β-myrcene occurs naturally as a constituent of the essential oils of plants such as hops, lemongrass, and derived products...
