Lipidome characterisation and sex-specific differences in type 1 and type 2 diabetes mellitus. Cardiovasc Diabetol 2024; 23:109. [PMID: 38553758 PMCID: PMC10981308 DOI: 10.1186/s12933-024-02202-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Accepted: 03/14/2024] [Indexed: 04/01/2024] Open
Abstract
BACKGROUND In this study, we evaluated the lipidome alterations caused by type 1 diabetes (T1D) and type 2 diabetes (T2D), by determining lipids significantly associated with diabetes overall and in both sexes, and lipids associated with the glycaemic state. METHODS An untargeted lipidomic analysis was performed to measure the lipid profiles of 360 subjects (91 T1D, 91 T2D, 74 with prediabetes and 104 controls (CT)) without cardiovascular and/or chronic kidney disease. Ultra-high performance liquid chromatography-electrospray ionization mass spectrometry (UHPLC-ESI-MS) was conducted in two ion modes (positive and negative). We used multiple linear regression models to (1) assess the association between each lipid feature and each condition, (2) determine sex-specific differences related to diabetes, and (3) identify lipids associated with the glycaemic state by considering the prediabetes stage. The models were adjusted by sex, age, hypertension, dyslipidaemia, body mass index, glucose, smoking, systolic blood pressure, triglycerides, HDL cholesterol, LDL cholesterol, alternate Mediterranean diet score (aMED) and estimated glomerular filtration rate (eGFR); diabetes duration and glycated haemoglobin (HbA1c) were also included in the comparison between T1D and T2D. RESULTS A total of 54 unique lipid subspecies from 15 unique lipid classes were annotated. Lysophosphatidylcholines (LPC) and ceramides (Cer) showed opposite effects in subjects with T1D and subjects with T2D, LPCs being mainly up-regulated in T1D and down-regulated in T2D, and Cer being up-regulated in T2D and down-regulated in T1D. Also, Phosphatidylcholines were clearly down-regulated in subjects with T1D. Regarding sex-specific differences, ceramides and phosphatidylcholines exhibited important diabetes-associated differences due to sex. Concerning the glycaemic state, we found a gradual increase of a panel of 1-deoxyceramides from normoglycemia to prediabetes to T2D. CONCLUSIONS Our findings revealed an extensive disruption of lipid metabolism in both T1D and T2D. Additionally, we found sex-specific lipidome changes associated with diabetes, and lipids associated with the glycaemic state that can be linked to previously described molecular mechanisms in diabetes.

Lipid profile, ox-LDL, and LCAT activity in patients with endometrial carcinoma and type 2 diabetes: The effect of concurrent disease based on a case-control study. Health Sci Rep 2023; 6:e1537. [PMID: 37662543 PMCID: PMC10472909 DOI: 10.1002/hsr2.1537] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Revised: 07/23/2023] [Accepted: 08/17/2023] [Indexed: 09/05/2023] Open
Abstract
Background and Aim The role of lecithin: cholesterol acyltransferase (LCAT) and oxidized low-density lipoprotein (ox-LDL) in endometrial cancer (EC) or EC with concurrent type 2 diabetes is still unclear. This study investigated the LCAT activity, ox-LDL, and lipid profile in EC patients with or without type 2 diabetes and compared them with healthy individuals and patients with type 2 diabetes alone. Methods In this cross-sectional, case-control study, 93 female participants were recruited. The participants were divided into four groups, including EC with type 2 diabetes (n = 19), EC without type 2 diabetes (n = 17), type 2 diabetes (n = 31), and healthy controls (n = 26). Sociodemographic information, the LCAT activity, triglyceride (TG), total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and ox-LDL levels were collected. One-way analysis of variance and analysis of covariance, Student's t-test, Mann-Whitney U-test, and χ 2-test were used to compare demographic features and laboratory results among studied groups. Regression analyses were also performed to evaluate the interaction effect between EC and type 2 diabetes on serum LCAT activity. Results The LCAT activity was significantly lower, and ox-LDL levels were significantly higher in all patient groups compared to the healthy controls (p < 0.001). EC patients had significantly lower LCAT activity and higher ox-LDL levels than type 2 diabetes and healthy groups (p < 0.05). Higher levels of TG and lower levels of HDL-C were observed in all patient groups compared to the healthy group (all p < 0.001). Patients with EC and concomitant type 2 diabetes had significantly lower serum LDL-C levels than healthy and type 2 diabetes groups (p < 0.05). Conclusions The combination of EC and type 2 diabetes had a subadditive effect on LCAT activity and ox-LDL level. The lowest LCAT activity and the highest ox-LDL levels were observed in patients with EC and concurrent type 2 diabetes.

Abstract
The increasing global burden of cardiometabolic diseases highlights the urgent clinical need for better personalized prediction and intervention strategies. Early diagnosis and prevention could greatly reduce the enormous socio-economic burden posed by these states. Plasma lipids including total cholesterol, triglycerides, HDL-C, and LDL-C have been at the center stage of the prediction and prevention strategies for cardiovascular disease; however, the bulk of cardiovascular disease events cannot be explained sufficiently by these lipid parameters. The shift from traditional serum lipid measurements that are poorly descriptive of the total serum lipidomic profile to comprehensive lipid profiling is an urgent need, since a wealth of metabolic information is currently underutilized in the clinical setting. The tremendous advances in the field of lipidomics in the last two decades has facilitated the research efforts to unravel the lipid dysregulation in cardiometabolic diseases, enabling the understanding of the underlying pathophysiological mechanisms and identification of predictive biomarkers beyond traditional lipids. This review presents an overview of the application of lipidomics in the study of serum lipoproteins in cardiometabolic diseases. Integrating the emerging multiomics with lipidomics holds great potential in moving toward this goal.

Abstract
Plasma cholesterol levels of high-density lipoproteins (HDL) have been associated with cardioprotection for decades. However, there is an evolving appreciation that this lipoprotein class is highly heterogeneous with regard to composition and functionality. With the advent of advanced lipid-testing techniques and methods that allow both the quantitation and recovery of individual particle populations, we are beginning to connect the functionality of HDL subspecies with chronic metabolic diseases. In this review, we examine type 2 diabetes (T2D) and explore our current understanding of how obesity, insulin resistance, and hyperglycemia affect, and may be affected by, HDL subspeciation. We discuss mechanistic aspects of how insulin resistance may alter lipoprotein profiles and how this may impact the ability of HDL to mitigate both atherosclerotic disease and diabetes itself. Finally, we call for more detailed studies examining the impact of T2D on specific HDL subspecies and their functions. If these particles can be isolated and their compositions and functions fully elucidated, it may become possible to manipulate the levels of these specific particles or target the protective functions to reduce the incidence of coronary heart disease.

Abstract
High-density lipoprotein cholesterol (HDL-c) has long been referred to as 'good cholesterol' due to its apparent inverse relationship with future CVD risk. More recent research has questioned a causal role for HDL-c in this relationship, however, as both genetic studies and numerous large-scale randomised controlled trials have found no evidence of a cardiovascular protective effect when HDL-c levels are raised. Instead, focus has switched to the functional properties of the HDL particle. Evidence suggests that both the composition and function of HDL may be significantly altered in the context of an inflammatory milieu, transforming the particle from a vasoprotective anti-atherogenic particle to a noxious pro-atherogenic equivalent. This review will summarise evidence relating HDL to CVD risk, explore recent evidence characterising changes in the composition and function of HDL that may occur in chronic inflammatory diseases, and discuss the potential for future HDL-modifying therapeutic interventions.

Abstract
INTRODUCTION High-density lipoprotein cholesterol comprises a group of heterogeneous subfractions that might have differential effects on atherosclerosis. Moreover, prior investigations suggest that the presence of diabetes (T2D) modifies the impact of some subfractions on atherosclerosis. In this study, we aimed to evaluate the association between high-density lipoprotein cholesterol subfractions and carotid intima-media thickness in the baseline assessment of the Brazilian Longitudinal Study of Adult Health participants from the São Paulo investigation centre. METHODS We evaluated 3930 individuals between 35 and 74 years without previous cardiovascular disease not using lipid-lowering drugs. High-density lipoprotein cholesterol subfractions (HDL2-C and HDL3-C) were measured by vertical ultracentrifugation (vertical auto profile). The relationship between each high-density lipoprotein cholesterol subfraction and carotid intima-media thickness was analysed by multiple linear regression models. RESULTS Total high-density lipoprotein cholesterol, as well as HDL2-C and HDL3-C, was negatively associated with carotid intima-media thickness after adjustment for demographic data (all p < 0.001) and traditional risk factors (all p < 0.05). When stratified by T2D status, the HDL2-C/HDL3-C ratio showed a negative association with carotid intima-media thickness in participants with T2D ( p = 0.032), even after fully controlling for confounding variables, including total high-density lipoprotein cholesterol. CONCLUSION HDL2-C, HDL3-C and HDL2/HDL3-C ratio are inversely associated with carotid intima-media thickness after adjustment for traditional risk factors. Association of the HDL2-C/HDL3-C ratio is modified by the presence of diabetes, being more pronounced in diabetic individuals.

Abstract
BACKGROUND Previous studies have demonstrated that hemoglobin-haptoglobin (Hb-Hp) complex plays a role in developing vascular complications in type 2 diabetes mellitus (T2DM). The complexes bind with Apolipoprotein A1 (ApoA1) of high-density lipoprotein (HDL), affecting the function of Lecithin:Cholesterol Acyltransferase (LCAT), and impairing the reverse cholesterol transport mechanism (RCT). This study investigated the influence of Hp phenotypes on serum levels of ApoA1 and LCAT in patients with T2DM. METHODS The study comprised 131 T2DM patients and 111 matching healthy controls. Fasting blood glucose, HbA1C, and lipid profile were determined by chemistry autoanalyzer, LCAT and ApoA1 by ELISA, and Hp phenotypes by gel electrophoresis. RESULTS Irrespective of Hp phenotypes, fasting blood glucose, HbA1C, and lipid profile were significantly higher in patients than in controls, while HDL-cholesterol, ApoA1, and LCAT were lower. ApoA1 correlated positively with LCAT (r=0.223, p=0.024) and HDL-cholesterol (r=0.255, 0.003) in patients only. When Hp polymorphism was taken into account, the levels of LCAT and ApoA1 were significantly lower in patients with Hp2-2 than that in patients of Hp1-1 and/or Hp2-1. Correlations between ApoA1 and each of HDL-cholesterol and LCAT (r=0.239, p=0.046, and r=0.252, p=0.040, respectively) were also observed, but only in patients with Hp2-2 phenotype. CONCLUSIONS The reduced levels of LCAT and ApoA1 observed in this study support the suggestion that T2DM patients with Hp2-2 phenotype could have altered RCT mechanism and increased risk of developing cardiovascular disease.

Abstract
Persons with type 2 diabetes mellitus (T2DM) have an elevated risk of atherosclerosis. High-density lipoproteins (HDL) normally protect against cardiovascular disease (CVD), but this may be attenuated by serum amyloid A (SAA). In a case-control study of young females, blood samples were compared between subjects with T2DM (n = 42) and individuals without T2DM (n = 42). SAA and apolipoprotein AI (apoAI) concentrations, paraoxonase-1 (PON-1), cholesteryl ester transfer protein (CETP), and lecithin-cholesterol acyltransferase (LCAT) activities were measured in the serum and/or HDL2 and HDL3 subfractions. SAA concentrations were higher in T2DM compared to controls: serum (30 mg/L (17, 68) versus 15 mg/L (7, 36); p = 0.002), HDL2 (1.0 mg/L (0.6, 2.2) versus 0.4 mg/L (0.2, 0.7); p < 0.001), and HDL3, (13 mg/L (8, 29) versus 6 mg/L (3, 13); p < 0.001). Serum-PON-1 activity was lower in T2DM compared to that in controls (38,245 U/L (7025) versus 41,109 U/L (5690); p = 0.043). CETP activity was higher in T2DM versus controls in HDL2 (232.6 μmol/L (14.1) versus 217.1 μmol/L (25.1); p = 0.001) and HDL3 (279.5 μmol/L (17.7) versus 245.2 μmol/L (41.2); p < 0.001). These results suggest that individuals with T2DM have increased SAA-related inflammation and dysfunctional HDL features. SAA may prove to be a useful biomarker in T2DM given its association with elevated CVD risk.

Diabetes induces gender gap on LCAT levels and activity. Life Sci 2012; 92:51-4.

Abstract
AIM High density lipoprotein (HDL) decreases in diabetic women more rapidly than what is observed in diabetic men. Here we aimed to study serum LCAT levels and LCAT activity in men and women with type 2 diabetes (T2DM) as well as healthy controls. MAIN METHODS We measured serum LCAT activity and levels in 40 patients with T2DM plus 40 age-sex and body mass index (BMI)-matched controls. The correlation between LCAT levels and activity was measured in the studied groups, stratified according to gender. KEY FINDINGS Patients had a lower LCAT activity, diastolic blood pressure, fasting blood sugar, triglyceride, low density lipoprotein cholesterol and a higher LCAT levels than controls. The lower LCAT activity in patients with T2DM was significant after multiple adjustments for age, LCAT levels and BMI, using general linear model (67.9 ± 1.8 vs. 86.5 ± 1.8; P<0.001). Women with T2DM had a lower LCAT activity and a higher LCAT and HDL levels compared to men. The lower LCAT activity in women remained significant after multiple adjustments for age, BMI and LCAT levels; (61.9 ± 3.1 vs. 74.17 ± 3.61; P<0.05). Statin treatment did not have any significant value on the results. HDL was not correlated with LCAT levels or activity in any of the studied populations. SIGNIFICANCE We showed that while LCAT activity is decreased in patients with T2DM, LCAT levels is increased. Patients with T2DM exhibit opposing effects on LCAT activity and LCAT production which is more severe in women. Future prospective studies may elucidate the underlying pathways for these observations.

Abstract
HDL is known to be inversely correlated with cardiovascular disease due to its diverse antiatherogenic functions. These functions include cholesterol efflux and reverse cholesterol transport, antioxidative and anti-inflammatory activities. However, HDL has been shown to undergo a loss of function in several pathophysiological states, as in the acute phase response, obesity and chronic inflammatory diseases. Some of these diseases were also shown to be associated with increased risk for cardiovascular disease. One such disease that is associated with HDL dysfunction and accelerated atherosclerosis is diabetes mellitus, a disease in which the HDL particle undergoes diverse structural modifications that result in significant changes in its function. This review will summarize the changes that occur in HDL in diabetes mellitus and how these changes lead to HDL dysfunction. Possible treatments for HDL dysfunction are also briefly described.

Abstract
Abstract
Objectives
The aim of this study was to determine the effects of Ajuga iva aqueous extract on lecithin : cholesterol acyltransferase (LCAT) activity and amount and composition of high-density lipoprotein (HDL)2 and (HDL)3, in streptozotocin (STZ)-induced diabetic rats.
Methods
Diabetes was induced in male Wistar rats by intraperitoneal injection of STZ (60 mg/kg body weight). Diabetic rats (n = 12) were divided into two groups. The diabetic control group (D) received a 20% casein diet and the diabetic treated group received the same diet supplemented with A. iva aqueous extract (0.5 g/100 g diet) (DAi), for 4 weeks.
Key findings
Total cholesterol and HDL3-C were respectively decreased by 32% and 55% in the DAi group compared with the D group, whereas HDL2-C was increased by 30%. The amounts of HDL2 and HDL3, which were the sum of apolipoproteins, unesterified cholesterol (UC), cholesteryl esters (CEs), triacylglycerols (TGs) and phospholipids (PLs), showed no significant difference. A. iva treatment increased LCAT by 33% and its cofactor-activator, apolipoprotein A-I, by 58%. HDL3-PL (enzyme substrate) and HDL3-UC (acyl group acceptor) were respectively decreased by 70% and 57%, whereas HDL2-CE (product of LCAT reaction) was enhanced by 30%.
Conclusions
In STZ-induced diabetic rats, A. iva improves reverse cholesterol transport by enhancing LCAT activity, leading to anti-atherogenic effects.

PLoS One 2011; 6:e23556.

Abstract
BACKGROUND High density lipoprotein (HDL) was reported to decrease plasma glucose and promote insulin secretion in type 2 diabetes patients. This investigation was designed to determine the effects and mechanisms of HDL on glucose uptake in adipocytes and glycogen synthesis in muscle cells. METHODS AND RESULTS Actions of HDL on glucose uptake and GLUT4 translocation were assessed with 1-[(3)H]-2-deoxyglucose and plasma membrane lawn, respectively, in 3T3-L1 adipocytes. Glycogen analysis was performed with amyloglucosidase and glucose oxidase-peroxidase methods in normal and palmitate-treated L6 cells. Small interfering RNA was used to observe role of scavenger receptor type I (SR-BI) in glucose uptake of HDL. Corresponding signaling molecules were detected by immunoblotting. HDL stimulated glucose uptake in a time- and concentration-dependent manner in 3T3-L1 adipocytes. GLUT4 translocation was significantly increased by HDL. Glycogen deposition got enhanced in L6 muscle cells paralleling with elevated glycogen synthase kinase3 (GSK3) phosphorylation. Meanwhile, increased phosphorylations of Akt-Ser473 and AMP activated protein kinase (AMPK) α were detected in 3T3-L1 adipocytes. Glucose uptake and Akt-Ser473 activation but not AMPK-α were diminished in SR-BI knock-down 3T3-L1 cells. CONCLUSIONS HDL stimulates glucose uptake in 3T3-L1 adipocytes through enhancing GLUT4 translocation by mechanisms involving PI3K/Akt via SR-BI and AMPK signaling pathways, and increases glycogen deposition in L6 muscle cells through promoting GSK3 phosphorylation.

Abstract
CONTEXT Lecithin:cholesterol acyltransferase (LCAT), which esterifies free cholesterol to cholesteryl esters, is required for normal plasma lipoprotein structure and is instrumental in high density lipoprotein (HDL) remodeling, but the relationship of variation in plasma LCAT activity with subclinical atherosclerosis is unclear. OBJECTIVES The aim of the study was to determine the effect of the metabolic syndrome (MetS) on plasma LCAT activity and its relationship with carotid artery intima media thickness (IMT). SETTING The study was conducted at the vascular laboratory of a university medical center. METHODS In 74 subjects with MetS and 90 subjects without MetS (National Cholesterol Education Program Adult Treatment Panel III criteria), mean carotid artery IMT, plasma lipids, LCAT activity (exogenous substrate method), high-sensitive C-reactive protein, and homeostasis model assessment insulin resistance (HOMA(ir)) were documented. RESULTS IMT was greater (P = 0.01) and plasma LCAT activity was higher (P < 0.001) in subjects with MetS compared to subjects without MetS. Similar increases in IMT and LCAT were found in MetS subjects without type 2 diabetes mellitus. Multiple linear regression analysis demonstrated that plasma LCAT activity was independently and positively related to HOMA(ir), plasma triglycerides, non-HDL cholesterol, and HDL cholesterol (all P < 0.001). After adjustment for age and sex, IMT was positively associated with LCAT activity (P < 0.01), independently of the presence of MetS (or alternatively of plasma lipids), HOMA(ir), and high-sensitive C-reactive protein. CONCLUSIONS Plasma LCAT activity is elevated in MetS and may be a marker of subclinical atherosclerosis. Our findings do not support the contention that strategies to elevate LCAT are necessarily beneficial for cardioprotection.
