Project description:Allium sativum (garlic) is considered the source of the diverse beneficial effects on thrombosis, heart disease, diabetes, nerve disorders and cancer, as well as being circulatory strengthening. We describe the global changes in transcriptomic activity from a short period of using a moderate amount of fresh garlic and its potential link to some of the beneficial effects.
Project description:This study utilized comparative global gene expression microarray analysis to evaluate the effects of a compound including garlic-derived secondary metabolites on intestinal immunity of chicken. Two-condition experiment, Garlic metabolites-fed chickens vs. Non-treated control chickens. Biological replicates: 2 control replicates, 2 Garlic metabolites-fed replicates with dye-switching.
Project description:Prolonged intervention studies investigating molecular metabolism are necessary for a deeper understanding of dietary effects on health. Here we provide mechanistic information about metabolic adaptation to fat-rich diets. Healthy men ingested saturated (SFA) or poly unsaturated (PUFA) fat-rich diets for six weeks during weight maintenance. Hyperinsulinemic clamps combined with leg balance technique revealed unchanged peripheral insulin sensitivity, independent of fatty acid type. Both diets increased fat oxidation potential in muscle. Hepatic insulin clearance increased, while glucose production, de novo lipogenesis and plasma triacylglycerol decreased. High fat intake changed the plasma proteome in immune-supporting direction and the gut microbiome displayed changes at taxonomical and functional level with PUFA. In mice, eucaloric feeding of human PUFA and SFA diets lowered hepatic triacylglycerol content compared to low-fat fed control mice, and induced adaptations in the liver supportive of decreased gluconeogenesis and lipogenesis. Intake of fat-rich diets thus induces extensive metabolic adaptations enabling disposition of dietary fat without metabolic complications.
Project description:Garlic is a popular flavor enhancer in modern cuisines. Although anti-atherosclerotic, anti-proliferative, hypolipidemic and chemopreventative effects of garlic are known for a long time, the mechanisms of garlic as a dietary supplement ramain largely unknown. We used microarrays to analyze the global programme of gene expression in control (cellulose) and garlic-fed mice and identified erythropoietic and heme biosynthetic genes that could, in part, be responsible for the pleiotropic effects of garlic on health Keywords: diet, garlic

We used microarrays to analyze the global programme of gene expression in control (cellulose) and garlic-fed mice and identified erythropoietic and heme biosynthetic genes that could, in part, be responsible for the pleiotropic effects of garlic on health Experiment Overall Design: 8-week old male C57BL/6J mice were divided into two diet groups and maintained at an SPF facility. Mice were fed (ad libitum) a special diet (Yeh and Yeh, 1994) with 4% cellulose (Control group, 3 mice) or 4% lyophilized raw garlic powder (Treatment group, 3 mice). At the end of the 15-week treatment, spleen organs were used for RNA isolation and arraying.

We used microarrays to analyze the global programme of gene expression in the liver tissues of control (cellulose) and garlic-fed C57BL/6J mice maintained at an SPF (Specific Pathogen Free) facility.
Project description:To characterize the expression of 58219 genes annotated from garlic genome, the transcriptomes of seven tissues (including garlic sprouts, shoots, bulbs, flowers, roots, pesudostems, and leaves) were sequenced, and finally identified 45,750 genes expressed in various tissues investigated. In addition, the bulbs-transcriptomes in the eight stages of bulbs-development were sequenced, resulting in 6,234 genes isentified to show dynamic expression changes in the bulbs-developmental process.

We used microarrays to analyze the global programme of gene expression in control (cellulose) and garlic-fed C57BL/6J mice serendipitously infected with Pasteurella multocida and identified acute phase response genes, particularly Lcn2 and Orm2, as the major players in the innate response. Also dieraty garlic suppressed pasteurella infection in C57BL/6J mice.
