From biosynthesis to function: the roles of ether lipids in cancer development and treatment
Hu Z, Wang Y, Liu C, Wu W, Zeng H and Zhou H
Cancer remains one of the most formidable diseases affecting human health, particularly because it involves complex reprogramming of metabolic pathways, especially pathways involved in lipid metabolism. Ether lipids (ELs), which alter membrane fluidity and signaling pathways that promote tumor initiation and development, have emerged as important regulators of cancer biology, positioning them as emerging candidate targets for diagnosis and treatment. The main focus of this review is the metabolic dysregulation of ELs in tumors, particularly the metabolic, genetic, and epigenetic processes that promote invasion, proliferation, and drug resistance. This review highlights preclinical treatment strategies designed to target EL synthases, aiming to provide novel perspectives for future translational applications that support more sustainable therapeutic options. In addition to future prospects centered on standardized detection and multiomics integration to improve precision oncology, important hurdles, including tissue specificity and metabolic heterogeneity, are covered.

Industrialized eating habits have disrupted the balance between n-6 to n-3 polyunsaturated fatty acids, a change reflected in human tissue composition. Increased n-6 to n-3 ratios may contribute to the emergence of several neurodevelopmental conditions. This study aims to determine how the balance between dietary n-6 and n-3 fatty acids relates to attention-deficit/hyperactivity disorder (ADHD) in kids and teenagers in the U.S.
Association between high-density lipoprotein cholesterol-related inflammation indices and chronic obstructive pulmonary disease: a cross-sectional study employing machine learning analysis
Hua X, Gan Y and Lv X
Chronic Obstructive Pulmonary Disease (COPD), defined by persistent airflow obstruction, is increasingly understood as a systemic inflammatory disorder. This condition is also frequently accompanied by profound metabolic dysregulation. The ratios comparing certain immune cell populations to High-density lipoprotein cholesterol (HDL-C) values are gaining attention as potential markers of inflammation in multiple chronic illnesses. However, the relationship connecting inflammatory indices related to HDL-C with the frequency of COPD occurrence is not yet well-established.

Tan Z, Chen Y, Ou Y, Shao X, Liu Q, Fu Y, Chen A, Bai G and Zhang J
Sun sensitivity, an abnormal skin reaction to ultraviolet radiation, increases the risk of melanoma and impairs the quality of life. In recent times, the body roundness index (BRI) has been suggested to be associated with various health conditions. Nevertheless, the association between the BRI and sun sensitivity remains not well understood. The purpose of this research was to investigate the association between the BRI and sun sensitivity.
Interactive effects of high-density lipoprotein cholesterol and insulin resistance on depression: results from the NHANES (2005-2018)
Rao L, Li J, Xian X, Hu Y and Xian Y
Prior studies on the relationship between high-density lipoprotein cholesterol (HDL-C) and depression have reported inconsistent results. Insulin resistance (IR) can alter the composition and function of HDL. This study aims to investigate whether IR influences the association between HDL-C and depression.
The association between different lipid indices and hyperuricemia in older adults: a cross-sectional study
Shen Y, Wang S, Qiu J, Li Y and Wang Y
Lipid-derived composite indices demonstrate robust epidemiological associations with diverse metabolic and cardiovascular disorders due to their integrative nature; however, their relationship with hyperuricemia (HUA) in older adults remains unexplored. This research examines the links between six blood lipid indices and HUA in older Chinese adults and assesses their diagnostic accuracy for HUA association stratification.
Single-cell and bulk transcriptome analyses revealed the role of macrophage cholesterol metabolism in atherosclerosis
Ke J, Chen S, Li L, Liao C, Peng F, Chai D and Lin J
Atherosclerosis (AS) is a complex cardiovascular disease characterized by dysregulated macrophage cholesterol metabolism (CM), a central driver of foam cell formation and plaque progression. However, how macrophage CM becomes dysregulated is still not fully understood. Single-cell RNA sequencing (scRNA-seq) was combined with bulk RNA-seq data to identify CM-related genes with diagnostic and therapeutic potential.
Age-multiplied low density lipoprotein cholesterol (LDL-C) burden (AM-LDL) index stratifies bleeding and ischemic risk in acute coronary syndrome: implications for early therapeutic intensification
Yu Y, Wang Y, Tuo X, Li Z, Li D and Chen Y
Early identification of high-risk individuals after Acute Coronary Syndrome (ACS) is critical for tailoring intensive lipid-lowering therapy, a cornerstone of secondary prevention to alleviate the growing global burden of cardiovascular diseases, while practical tools integrating lipid burden and vascular aging remain lacking. This study proposes the age-multiplied low density lipoprotein cholesterol (LDL-C) burden (AM-LDL) index to quantify cumulative atherogenic exposure and stratify 1-year ischemic and bleeding risk.
