Article Synopsis
  • Fish oil supplementation's effects on plasma lipids vary among individuals, potentially due to genetic differences, specifically focusing on 12 SNPs related to dyslipidaemia.
  • In a study with 310 participants over 12 months, the presence of risk alleles was linked to higher triglyceride levels and lower high-density lipoprotein (HDL) cholesterol, while certain genotypes showed varied responses to fish oil doses.
  • Specifically, individuals with the FADS1 rs174546 risk allele experienced a significant reduction in triglyceride levels when consuming higher doses of EPA and DHA, indicating personalized benefits of fish oil based on genetic makeup.

Blood pressure is a heritable determinant of cardiovascular disease (CVD) risk. Recent genome-wide association studies have identified several single-nucleotide polymorphisms (SNPs) associated with blood pressure, including rs1378942 in the c-Src tyrosine kinase (CSK) gene. Fish oil supplementation provides inconsistent protection from CVD, which may reflect genetic variation.

Fish oil supplementation provides an inconsistent degree of protection from cardiovascular disease (CVD), which may be attributed to genetic variation. Single nucleotide polymorphisms (SNPs) in the elongation-of-very-long-chain-fatty-acids-2 (ELOVL2) gene have been strongly associated with plasma proportions of n-3 long-chain polyunsaturated fatty acids (LC-PUFA). We investigated the effect of genotype interaction with fish oil dosage on plasma n-3 LC-PUFA proportions in a parallel double-blind controlled trial, involving 367 subjects randomised to treatment with 0.

Marine n3 polyunsaturated fatty acids (PUFAs) activate the transcription factor peroxisome proliferator-activated receptor (PPARγ), which modulates the expression of adiponectin. We investigated the interaction of dietary n3 PUFAs with adiponectin gene (ADIPOQ) single nucleotide polymorphism (SNP) genotypes as a determinant of serum adiponectin concentration. The Modulation of Atherosclerosis Risk by Increasing Doses of n3 Fatty Acids study is a parallel design, double-blind, controlled trial.

Article Synopsis
  • Delta-5 and delta-6 desaturases are enzymes crucial for synthesizing long-chain polyunsaturated fatty acids (PUFAs) in the body.
  • In a study of 310 healthy individuals, specific genetic variants in the FADS1-FADS2 gene cluster were linked to changes in desaturase activity and the balance of PUFAs in the blood.
  • A dietary intervention increasing intake of EPA and DHA demonstrated that these fats can significantly affect the activity of the desaturase enzymes, with certain genetic factors influencing how effective this dietary change is.

Background: The dietary intake of n-3 (omega-3) long-chain PUFAs (LC-PUFAs) from fish may improve endothelial function and arterial stiffness.

Objective: The objective was to test the hypothesis that increasing intakes of n-3 LC-PUFAs-equivalent to the consumption of 1, 2, or 4 portions of oily fish per week-favorably affects endothelial function and arterial stiffness.

Design: A parallel-design, randomized, double-blind study compared daily doses of 0.

Radiation-induced complex double-strand breaks (DSBs) characterised by base lesions, abasic sites or single-strand breaks in close proximity to the break termini, are believed to be a major cause of the biological effects of ionising radiation exposure. It has been hypothesised that complex DSBs pose problems for the repair machinery of the cell. Using a biochemical approach, we have investigated the challenge to two major repair processes: base excision repair and ligation of DSB ends.

In mammals growth hormone (GH) is generally a strongly conserved protein, reflecting a slow rate of molecular evolution. However, during primate and artiodactyl evolution episodes of rapid change occurred, so that the GHs of higher primates and ruminants differ markedly from those of other mammals. To extend knowledge of GH evolution in Cetartiodactyla (Artiodactyla plus Cetacea) we have previously characterized GH genes from several members of this group, including the common dolphin.

The sequence of growth hormone (GH) is generally strongly conserved in mammals, but episodes of rapid change occurred during the evolution of primates and artiodactyls, when the rate of GH evolution apparently increased substantially. As a result the sequences of higher primate and ruminant GHs differ markedly from sequences of other mammalian GHs. In order to increase knowledge of GH evolution in Cetartiodactyla (Artiodactyla plus Cetacea) we have cloned and characterized GH genes from camel (Camelus dromedarius), hippopotamus (Hippopotamus amphibius), and giraffe (Giraffa camelopardalis), using genomic DNA and a polymerase chain reaction technique.

The sequence of growth hormone (GH) is generally strongly conserved in mammals, but episodes of rapid change occurred during the evolution of primates and artiodactyls, when the rate of GH evolution apparently increased at least 50-fold. As a result, the sequences of human and ruminant GHs differ substantially from those of other non-primate GHs. Recent molecular studies have suggested that cetaceans are closely related to artiodactyls and may be deeply nested within the artiodactyl phylogenetic tree.
