We describe the discovery of small molecule benzazepine derivatives as agonists of human peroxisome proliferator-activated receptor δ (PPARδ) that displayed excellent selectivity over the PPARα and PPARγ subtypes. Compound 8 displayed good PK in the rat and efficacy in upregulation of pyruvate dehydrogenase kinase, isozyme 4 (PDK4) mRNA in human primary myotubes, a biomarker for increased fatty acid oxidation.

Purpose Of Review: While lipid-lowering therapies demonstrate efficacy, many patients still contend with significant residual risk of atherosclerotic cardiovascular diseases (ASCVD). The intestine plays a pivotal role in regulating circulating lipoproteins levels, thereby exerting influence on ASCVD pathogenesis. This review underscores recent genetic findings from the last six years that delineate new biological pathways and actors in the intestine which regulate lipid-related ASCVD risk.

Recent studies have suggested that the interaction between diet and an individual's genetic predisposition can determine the likelihood of obesity and various metabolic disorders. The current study aimed to examine the association of dietary branched-chain amino acids(BCAAs) and aromatic amino acids(AAAs) with the expression of the leptin and FTO genes in the visceral and subcutaneous adipose tissues of individuals undergoing surgery. This cross-sectional study was conducted on 136 Iranian adults, both men and women, aged ≥18 years.

Bone serves as a fundamental structural component in the body, playing pivotal roles in support, protection, mineral supply, and hormonal regulation. However, critical-sized bone injuries have become increasingly prevalent, necessitating extensive medical interventions due to limitations in the body's capacity for self-repair. Traditional approaches, such as autografts, allografts, and xenografts, have yielded unsatisfactory results.

Hepatocellular carcinoma (HCC) remains a malignant and life-threatening tumor with an extremely poor prognosis, posing a significant global health challenge. Despite the continuous emergence of novel therapeutic agents, patients exhibit substantial heterogeneity in their responses to anti-tumor drugs and overall prognosis. The pentose phosphate pathway (PPP) is highly activated in various tumor cells and plays a pivotal role in tumor metabolic reprogramming.

Curr Nutr Rep
January 2025
Department of Internal Medicine, Mayo Clinic, Rochester, MN, USA.
Purpose Of Review: This review aims to determine whether muscle mass and function can be effectively maintained without relying on animal-based protein sources. We evaluate the quality, digestibility, and essential amino acid profiles of plant-based proteins to understand their potential in preventing and managing sarcopenia.
Recent Finding: Recent studies indicate that while animal-based proteins have traditionally been considered the gold standard for supporting muscle protein synthesis, certain plant-based protein blends, fortified with leucine or other essential amino acids, can produce comparable anabolic responses.
