High density lipoprotein cholesterol and cancer: Marker or causative?

Prog Lipid Res 2018 07 4;71:54-69. Epub 2018 Jun 4.

Department of Hypertension, WAM University Hospital in Lodz, Medical University of Lodz, Zeromskiego 113, Lodz, Poland; Polish Mother's Memorial Hospital Research Institute (PMMHRI), Lodz, Poland; Cardiovascular Research Centre, University of Zielona Gora, Zielona Gora, Poland. Electronic address:

The relationship between high-density lipoproteins (HDLs), HDL-cholesterol (HDLC) and cancer incidence and mortality is controversial. Although most studies conducted so far, including well-designed prospective studies and meta-analyses, have revealed a significant inverse association between HDL-C levels and cancer risk, several confounding factors and opposite results showing either a direct or an inverse association between HDL-C levels and cancer mortality have hindered the possibility to derive definitive conclusions. Moreover, different lines of research also pointed out that this association might actually reflect an inverse causality, which would imply that low HDL-C levels merely represent an epiphenomenon of cancer-related inflammation and cancer cell renewal.

Structural determinants in ApoA-I amyloidogenic variants explain improved cholesterol metabolism despite low HDL levels.

Biochim Biophys Acta Mol Basis Dis 2017 12 6;1863(12):3038-3048. Epub 2017 Sep 6.

Department of Experimental Medical Science, Lund University, 221 84 Lund, Sweden. Electronic address:

Twenty Apolipoprotein A-I (ApoA-I) variants are responsible for a systemic hereditary amyloidosis in which protein fibrils can accumulate in different organs, leading to their failure. Several ApoA-I amyloidogenic mutations are also associated with hypoalphalipoproteinemia, low ApoA-I and high-density lipoprotein (HDL)-cholesterol plasma levels; however, subjects affected by ApoA-I-related amyloidosis do not show a higher risk of cardiovascular diseases (CVD). The structural features, the lipid binding properties and the functionality of four ApoA-I amyloidogenic variants were therefore inspected in order to clarify the paradox observed in the clinical phenotype of the affected subjects.

Reduced platelet count, but no major platelet function abnormalities, are associated with loss-of-function ATP-binding cassette-1 gene mutations.

Clin Sci (Lond) 2017 Aug 24;131(16):2095-2107. Epub 2017 Jul 24.

Unità di Medicina III, ASST Santi Paolo e Carlo and Dipartimento di Scienze della Salute, Università degli Studi di Milano, Milan, Italy.

Loss-of-function mutations of the the ATP-binding cassette-1 () gene are the cause of Tangier disease (TD) in homozygous subjects and familial HDL deficiency (FHD) in heterozygous subjects. These disorders are characterized by reduced plasma HDL-cholesterol (HDL-C) and altered efflux of cholesterol from cells. Previous studies in TD patients and murine models reported defects in platelet count, morphology, and function, but the issue is still controversial. Read More

Centro E. Grossi Paoletti, Dipartimento di Scienze Farmacologiche e Biomolecolari Università degli Studi di Milano, Milano, Italy

The aim of this study was to evaluate the vasoprotective effects of HDL isolated from carriers of LCAT deficiency, which are characterized by a selective depletion of LpA-I:A-II particles and predominance of preβ migrating HDL. HDLs were isolated from LCAT-deficient carriers and tested in vitro for their capacity to promote NO production and to inhibit vascular cell adhesion molecule-1 (VCAM-1) expression in cultured endothelial cells. HDLs from carriers were more effective than control HDLs in promoting eNOS activation with a gene-dose-dependent effect ( = 0. Read More

Methods for Monitoring ABCA1-Dependent Sterol Release.

Methods Mol Biol 2017 ;1583:257-273

Department of Biochemistry, Geisel School of Medicine at Dartmouth, 7200 Vail Bldg. Room 304, Hanover, NH, 03755, USA.

Releasing sterols to the extracellular milieu is an important part of sterol homeostasis in cells and in the body. ATP-binding cassette transporter A1 (ABCA1) plays an essential role in cellular phospholipid and sterol release to lipid-free or lipid-poor apolipoprotein A-I (apoA-I), the major apolipoprotein in high-density lipoprotein (HDL), and constitutes the first step in the formation of nascent HDL. Loss-of-function mutations in the ABCA1 gene lead to a rare disease known as Tangier disease that causes severe deficiency in plasma HDL level. Read More

Poor glycemic control in type 2 diabetes enhances functional and compositional alterations of small, dense HDL3c.

Biochim Biophys Acta Mol Cell Biol Lipids 2017 Feb 2;1862(2):188-195. Epub 2016 Nov 2.

INSERM UMR_S 1166, Faculte de Medecine Pitie-Salpetriere, 91 Bld de l'Hopital, 75013 Paris, France; University of Pierre and Marie Curie - Paris 6, Paris, France. Electronic address:

High-density lipoprotein (HDL) possesses multiple biological activities; small, dense HDL3c particles displaying distinct lipidomic composition exert potent antiatherogenic activities which can be compromised in dyslipidemic, hyperglycemic insulin-resistant states. However, it remains indeterminate (i) whether such functional HDL deficiency is related to altered HDL composition, and (ii) whether it originates from atherogenic dyslipidemia, dysglycemia, or both. In the present work we analyzed compositional characteristics of HDL subpopulations and functional activity of small, dense HDL3c particles in treatment-naïve patients with well-controlled (n=10) and poorly-controlled (n=8) type 2 diabetes (T2D) and in normolipidemic age- and sex-matched controls (n=11).

Diagnosis and treatment of high density lipoprotein deficiency.

Prog Cardiovasc Dis 2016 Sep - Oct;59(2):97-106. Epub 2016 Aug 24.

Cardiovascular Nutrition Laboratory, Human Nutrition Research Center on Aging at Tufts University and Tufts University School of Medicine, Boston, MA; Boston Heart Diagnostics, Framingham, MA.

Low serum high density lipoprotein cholesterol level (HDL-C) <40 mg/dL in men and <50 mg/dL in women is a significant independent risk factor for cardiovascular disease (CVD), and is often observed in patients with hypertriglyceridemia, obesity, insulin resistance, and diabetes. Patients with marked deficiency of HDL-C (<20 mg/dL) in the absence of secondary causes are much less common (<1% of the population). These patients may have homozygous, compound heterozygous, or heterozygous defects involving the apolipoprotein (APO)AI, ABCA1, or lecithin:cholesterol acyl transferase genes, associated with apo A-I deficiency, apoA-I variants, Tangier disease , familial lecithin:cholesteryl ester acyltransferase deficiency, and fish eye disease.

Targeted Proteomics Identifies Paraoxonase/Arylesterase 1 (PON1) and Apolipoprotein Cs as Potential Risk Factors for Hypoalphalipoproteinemia in Diabetic Subjects Treated with Fenofibrate and Rosiglitazone.

Mol Cell Proteomics 2016 Mar 14;15(3):1083-93. Epub 2015 Dec 14.

From the ‡Department of Medicine, University of Washington, Seattle, WA, 98109;

Low levels of high-density lipoprotein cholesterol (HDL-C) and high triglyceride levels contribute to the excess rate of cardiovascular events seen in subjects with type 2 diabetes. Fenofibrate treatment partially reverses dyslipidemia in these subjects. However, a paradoxical marked reduction in HDL-C and HDL's major protein, apolipoprotein A-I, is a complication of fenofibrate in combination with rosiglitazone, an insulin-sensitizing agent.

Exp Cell Res 2015 Oct 1;338(1):105-12. Epub 2015 Aug 1.

Department of Pharmacological and Biomolecular Sciences, Laboratory of Pharmacology of Dyslipidemias and Atherosclerosis, Università degli Studi di Milano, Milan, Italy.

Cutaneous lipids, endogenously synthetized and transported by lipoproteins, play a pivotal role in maintaining skin barrier. An impairment of extracutaneous lipid trafficking leads to the development of xanthomas, mostly arising in hyperlipidemic patients, but also in subjects with high-density lipoprotein (HDL) deficiency. The aim of this work was to evaluate, in a genetically modified mouse model, lacking two protein components of HDL particles, apolipoprotein(apo)E and apoA-I, the effect of HDL deficiency on skin morphology.

Whole exome sequencing combined with integrated variant annotation prediction identifies asymptomatic Tangier disease with compound heterozygous mutations in ABCA1 gene.

Atherosclerosis 2015 Jun 7;240(2):324-9. Epub 2015 Apr 7.

Division of Cardiovascular Medicine, Kanazawa University, Graduate School of Medicine, Kanazawa, Japan.

Objective: Molecular diagnosis for subjects with extremely low HDL-C through candidate-gene approaches requires huge effort. Whole exome-sequencing (WES) has already shown approximately ∼30% success in the diagnosis of Mendelian disorders. Moreover, novel in silico prediction software for the pathogenicity of novel missense variants named Combined Annotation Dependent Depletion (CADD) has recently been developed, enabling the objective integration of many diverse annotations into a single measure (C-score) for each variant.

Role of HDL in those with diabetes.

Curr Cardiol Rep 2014 Sep;16(9):512

Low levels of high-density lipoprotein cholesterol (HDL-C) have been associated with an increased risk of coronary heart disease in prospective population studies and clinical trials of high-risk patients treated with a low to moderate intensity statin. As a result, therapeutic targets were developed to increase concentrations of HDL-C. Subsequently, clinical trials of high-intensity statins have not supported this previously well-established association. Read More

Acquired lecithin:cholesterol acyltransferase deficiency as a major factor in lowering plasma HDL levels in chronic kidney disease.

J Intern Med 2015 May 1;277(5):552-61. Epub 2014 Aug 1.

Center E. Grossi Paoletti, Department of Pharmacological and Biomolecular Sciences, Università degli Studi di Milano, Milan, Italy.

Objectives: It has been suggested that a low plasma high-density lipoprotein cholesterol (HDL-C) level contributes to the high cardiovascular disease risk of patients with chronic kidney disease (CKD), especially those undergoing haemodialysis (HD). The present study was conducted to gain further understanding of the mechanism(s) responsible for the low HDL-C levels in patients with CKD and to separate the impact of HD from that of the underlying CKD.

Methods: Plasma lipids and lipoproteins, HDL subclasses and various cholesterol esterification parameters were measured in a total of 248 patients with CKD, 198 of whom were undergoing HD treatment and 40 healthy subjects. Read More
