Background: Obesity is associated with enhanced lipid accumulation and the expansion of adipose tissue accompanied by hypoxia and inflammatory signalling. Investigation in human subcutaneous white adipose tissue (scWAT) in people living with obesity in which metabolic complications such as insulin resistance are yet to manifest is limited, and the mechanisms by which these processes are dysregulated are not well elucidated. Long chain omega-3 polyunsaturated fatty acids (LC n-3 PUFAs) have been shown to modulate the expression of genes associated with lipid accumulation and collagen deposition and reduce the number of inflammatory macrophages in adipose tissue from individuals with insulin resistance.

Background: Obesity is associated with enhanced inflammation. However, investigation in human subcutaneous white adipose tissue (scWAT) is limited and the mechanisms by which inflammation occurs have not been well elucidated. Marine long chain omega-3 polyunsaturated fatty acids (LC n-3 PUFAs) have anti-inflammatory actions and may reduce scWAT inflammation.

Obesity is believed to be associated with a dysregulated endocannabinoid system which may reflect enhanced inflammation. However, reports of this in human white adipose tissue (WAT) are limited and inconclusive. Marine long-chain omega-3 polyunsaturated fatty acids (LC n-3 PUFAs) have anti-inflammatory actions and therefore may improve obesity-associated adipose tissue inflammation.

Article Synopsis
  • The study investigates how early life DNA methylation of the SLC6A4 gene could predict later obesity and metabolic issues, linking it to serotonin levels and energy regulation.
  • Researchers measured DNA methylation in different populations: children, adolescents, and adults using various methods, including pyrosequencing.
  • Results showed that lower methylation of a specific site (CpG5) on the SLC6A4 gene was associated with higher fat mass and skinfold thickness in children and adolescents, indicating that maternal factors also play a role.

Article Synopsis
  • Early life environment significantly influences obesity risk through epigenetic changes, specifically DNA methylation.
  • A novel link was found between methylation levels of the ANRIL gene at birth and increased childhood adiposity by age six, supported by findings in diverse populations.
  • This study suggests that methylation patterns are meaningful indicators of future weight gain and highlight the importance of early environmental factors on long-term health outcomes.

Background: Plasma lysophospholipids have emerged as signaling molecules with important effects on inflammation, insulin resistance, and fatty liver disease, each of which is linked closely to obesity. Dietary n-3 (ω-3) polyunsaturated fatty acids (PUFAs) may be able to improve these conditions.

Objective: The objective of this study was to assess the response of plasma lysophospholipids to obesity, n-3 PUFA consumption, and a high-fat meal challenge to better understand the role of lysophospholipid metabolism in the progression of obesity-related disorders.

Unlabelled: Preliminary work suggested that perioperative immunonutrition (IMN) enriched in n-3 fatty acids, arginine, and nucleotides may improve preoperative nutritional status, enhance postoperative recovery, and reduce postoperative infectious complications in patients undergoing liver transplantation (LT). The current study examined these outcomes in a double-blind, randomized, controlled trial. Patients wait-listed for LT (n = 120) were randomized to either supplemental (0.
