Cholesterol ester transfer protein (CETP) plays a key role in remodeling triglyceride-rich particles and high-density lipoproteins (HDL). We investigated CETP sequence variants in response to long-term overfeeding (100 days) in 12 pairs of male monozygotic twins (mean age+/-S.D.: 21+/-2 years). Body fat mass (FM), abdominal subcutaneous (ASF) and visceral fat (AVF), and plasma lipoproteins were determined. The CETP variants C>T/In9 (rs289714) and G>A/Ex14 (rs5882, or I405V) were investigated by RFLP-PCR methodologies. Before overfeeding, the CETP CC/In9 (n=18) genotype was associated with lower FM compared to the C>T/In9 heterozygotes. Overfeeding induced more FM and ASF accretion in C>T/In9 carriers (P

Maternal obesity puts the offspring at high risk of developing obesity and cardio-metabolic diseases in adulthood. Here, we utilized a mouse model of maternal high-fat diet (HFD)-induced obesity that recapitulates metabolic perturbations seen in humans. We show increased adiposity in the offspring of HFD-fed mothers (Off-HFD) when compared to the offspring regular diet-fed mothers (Off-RD).

Unintentional weight loss in older populations is linked to greater mortality and morbidity risks. This study aims to understand the metabolic mechanisms of unintentional weight loss and their relationship with body composition changes in older adults. We investigated plasma metabolite associations with weight and body composition changes over 5 years in 1335 participants (mean age 73.

Elevated lipoprotein(a) [Lp(a)] levels are increasingly recognized as a significant risk factor for cardiovascular diseases and may also contribute to atrial fibrillation (AF). This review investigated the indirect mechanisms through which Lp(a) may influence AF, including proatherogenic, prothrombotic, and proinflammatory pathways. Traditional lipid-lowering therapies, such as lifestyle modifications and statins, have limited effects on Lp(a) levels.

As an important part of lipid metabolism the liver produces large particles called very low density lipoproteins, filled mostly with triglyceride and cholesterol esters mixture. A large percentage of the mixture composition components has a melting point above physiological temperature. Thus solid cluster formation or phase transition could be expected.

Background: Lipid metabolism, one of the three major metabolic processes, plays a crucial role in male fertility, particularly when lipid homeostasis is disrupted. Lipid droplets (LDs), cellular organelles that store lipids primarily in the form of triglycerides and cholesterol esters, serve as central hubs in lipid metabolism.The degradation of LDs is regulated by lipases and lipophagy.
