Background: Apolipoprotein M (apoM) is a recently identified apolipoprotein associated with high-density lipoprotein (HDL) in coronary artery disease (CAD), but the association between apoM polymorphism and obesity has not been reported.
Aim: To investigate the association between apoM polymorphism and obesity prevalence in 584 Korean adults.
Methods: A total of 584 individuals aged between 30 and 80 years were recruited from Yonsei Medical Center in Seoul, Korea, and divided into obese (OB; body mass index, BMI ≥25) and nonobese (non-OB; BMI <25) groups. Anthropometric variables, lipid profiles, insulin-resistant profiles, reverse cholesterol transport (RCT) enzymes, HDL subfraction, and apoM polymorphism were determined.
Results: In OB with T-855C polymorphism, TT genotype carriers significantly showed 6.2% higher diastolic blood pressure (DBP), 1.3% lower amount of HDL2b subfraction, and 19.7% higher lecithin-cholesterol acyltransferase (LCAT) mass than TC+CC carriers. OB subjects with the T allele of T-778C polymorphism significantly demonstrated 43% higher plasma insulin, 17.7% higher total cholesterol, 26.7% higher triglyceride, 40.7% higher leptin, 1.6% lower HDL2b, and 12.6% higher LCAT mass than those with the C allele. These results were reversed in non-OB with T-778C polymorphism regarding HDL subfractions and RCT enzymes.
Conclusion: apoM T-855C and T-778C polymorphisms were found to be associated with obesity by regulating HDL metabolism, and the T alleles of apoM T-778C were shown to be more strongly correlated.

Background: Apolipoproteins as an integral part of lipoproteins are crucial for the transport and metabolism of lipids. However, there is a lack of longitudinal studies to quantify the concentrations of maternal apolipoproteins from preconception to postpartum and their associations with maternal metabolic health and offspring birth outcomes.
Methods: Quantification of apolipoproteins was performed on maternal plasma samples (N = 243 trios) collected at preconception, 26-28 weeks' pregnancy, and three months postpartum in the Singapore PREconception Study of long-Term maternal and child Outcomes (S-PRESTO) cohort study.

Introduction: Pancreatic ductal adenocarcinoma (PDAC) has the highest mortality rate among all solid tumors. Tumorigenesis is promoted by the oncogene KRAS, and KRAS mutations are prevalent in patients with PDAC. Therefore, a comprehensive understanding of the interactions between KRAS mutations and PDAC may expediate the development of therapeutic strategies for reversing the progression of malignant tumors.

Unlabelled: Type 1 diabetes mellitus (T1DM), associated with autoimmune destruction of pancreatic β cells, is observed in children and adolescents.
Objective: We investigated the potential association of the apolipoprotein M () polymorphisms rs707921, rs805264, rs805296, rs805297, and rs9404941 in childhood-onset T1DM ( = 144) and compared them to those in healthy (mostly Euro-Brazilian) children ( = 168).
Methods: This project was approved by the Ethics Committee of the Federal University of Parana (CAAE 24676613.

Background: Apolipoprotein M (ApoM) may have a role in the susceptibility of type 2 diabetes mellitus (T2DM). Polymorphisms in the promoter region of the ApoM gene were found to be significantly associated with diabetes. The aim of this study was to investigate the association of ApoM SNP rs805297 (C-1065A) with the susceptibility of T2DM and related microvascular complications in South Egypt.

Context: Recent studies have discovered a role of apolipoprotein M (apoM) in energy metabolism, and observational analyses in humans suggest an association with type 2 diabetes. The causal relationship remains however elusive.
Objective: To investigate whether reduced plasma apoM concentrations are causally linked to increased risk of type 2 diabetes.
