Targeting lipid metabolism in multiple myeloma cells: rational development of a synergistic strategy with proteasome inhibitors. Br J Pharmacol 2021; 178:4741-4757. [PMID: 34378191 DOI: 10.1111/bph.15653] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2020] [Revised: 07/05/2021] [Accepted: 07/12/2021] [Indexed: 11/28/2022] Open
Abstract
BACKGROUND AND PURPOSE Aberrant lipid metabolism is now recognized as a key feature of cancer cells. Our initial research on mass spectrometry-based analysis of lipids in a multiple myeloma (MM) cell line showed a significant accumulation of lipids in MM cells after proteasome inhibition. This finding prompted us to hypothesize that MM cell survival depends on the maximal utilization of abnormally accumulated lipids. Therefore, we explored whether lipid metabolism-modulating agents would synergize with proteasome inhibitors (PIs). EXPERIMENTAL APPROACH The abnormal massive lipid accumulation in MM cells was detected using mass spectrometry. Cell viability and cell apoptosis were detected to assess the synergistic effect of lipid regulators and PIs. Otherwise, a novel stable derivative (FCE) of fenofibrate (FEN) was synthesized and used to treat MM cells in vitro and in vivo along with ixazomib. ChIP-seq, western blotting and RT-qPCR were performed to explore the potential mechanism underlying the increase in lipid levels in MM cells after proteasome inhibition. KEY RESULTS The accumulation of lipids in MM cells was induced by proteasome inhibition. Lipid-lowering drugs and MG-132 exerted a synergistic effect to kill MM cells. FCE showed significant synergistic activity in vitro and in vivo with ixazomib. The abnormal lipid accumulation in MM cells that was enhanced by proteasome inhibitors might be due to the elevated SREBP1/2 expression induced by ATF4. CONCLUSIONS AND IMPLICATIONS In summary, the results provide a proof of principle and rationale for the further clinical evaluation of the combination of lipid-modulating drugs with proteasome inhibitors.

Abstract
BACKGROUND Proteinuria often changes dynamically, showing either regression or progression. The impact of changes in proteinuria on future stroke risk remains largely unknown. We hypothesized that changes in proteinuria would be associated with stroke risk in patients with diabetes mellitus and prediabetes mellitus. METHODS AND RESULTS The study population included 17 380 participants with diabetes mellitus or prediabetes mellitus enrolled in a prospective Chinese cohort. From the baseline and 2-year dipstick screening results, participants were classified as having no proteinuria or remittent, incident, or persistent proteinuria. Reduction in proteinuria was calculated as the baseline minus 2-year proteinuria. Stroke outcomes were assessed in subsequent follow-ups. Data were analyzed using Cox proportional-hazards models. During a median follow-up of 6.9 years, we identified 751 patients with stroke. Stroke risk was increased for participants with persistent (hazard ratio [HR], 1.64; 95% confidence interval [CI], 1.18-2.30), incident (HR, 1.52; 95% CI, 1.22-1.89), and remittent (HR, 1.42; 95% CI, 1.01-2.02) proteinuria compared with those with no proteinuria. Persistent proteinuria was associated with a higher risk of stroke for participants with prediabetes mellitus (HR, 2.58; 95% CI, 1.58-4.22) compared with those with diabetes mellitus (HR, 1.35; 95% CI, 0.86-2.12 [P for interaction=0.0083]). Proteinuria reduction contributed to a decrease in stroke incidence (HR, 0.88; 95% CI, 0.81-0.95). The results were confirmed by sensitivity analyses. CONCLUSIONS Persistent, incident, and remittent proteinuria are independent indicators of stroke risk in both diabetic and prediabetic populations.

Abstract
INTRODUCTION Peroxisome proliferator-activated receptor-α (PPAR-α) agonists can regulate metabolism and protect the cardiovascular system. This study investigated the effects of PPAR-α agonist fenofibrate on insulin resistance in patients with impaired glucose tolerance (IGT). METHODS This research evaluated cross-sectional and interventional studies. 191 subjects with IGT were divided into a hypertriglyceridemia group (HTG group, n = 118) and a normal triglyceride (TG) group (NTG group, n = 73). 79 subjects with normal glucose tolerance were recruited as a control group. The HTG group was treated with fenofibrate (200 mg/day) for 12 weeks. The homeostatic model assessment index 2 (HOMA2) and the McAuley index (McA) were calculated. RESULTS HOMA2 for β-cell function (HOMA2-%B) was 93.47 ± 26.28, 68.47 ± 21.29, and 79.92 ± 23.15 in HTG, NTG, and control groups, respectively. HOMA2 for insulin sensitivity (HOMA2-%S) was 48.40 (39.70, 68.70), 110.20 (62.55, 141.95), and 101.20 (79.90, 140.10) in HTG, NTG, and control groups, respectively. HOMA2 for insulin resistance (HOMA2-IR) was 2.09 (1.46, 2.52), 0.92 (0.70, 1.61), and 0.99 (0.71, 1.25) in HTG, NTG, and control groups, respectively. McA was 5.05 ± 0.76, 7.99 ± 1.79, and 8.34 ± 1.55 in HTG, NTG, and control groups, respectively. The HTG group had higher HOMA2-%B and HOMA2-IR, and lower HOMA2-%S and McA than NTG and control groups (P < 0.001 for all). Fenofibrate decreased HOMA2-%B and HOMA2-IR and increased HOMA2-%S and McA in the HTG group (HOMA2-%B: from 93.47 ± 26.28 to 89.34 ± 23.53, P = 0.018; HOMA2-%S: from 48.40 (39.70, 68.70) to 56.75 (44.88, 72.53), P < 0.001; HOMA2-IR: from 2.07 (1.46, 2.52) to 1.76 (1.38, 2.30), P < 0.001; McA: from 5.05 ± 0.76 to 9.34 ± 0.88, P < 0.001). CONCLUSION PPAR-α agonists improve parameters of glucoregulation in IGT patients with hypertriglyceridemia.

Abstract
: Older adults with diabetes are at higher risk for atherosclerotic cardiovascular disease (ASCVD) than younger adults with diabetes and older adults without diabetes. The rationale to implement ASCVD risk-lowering therapies in older adults with diabetes is compelling. Recommendations for lifestyle modification, lipid-lowering therapy, blood pressure management, blood glucose control, and aspirin therapy are often based on studies that show their efficacy in younger populations. However, the risks associated with each of these interventions increase with age, and favorable risk-to-benefit ratios demonstrated in younger adults with diabetes are less certain in older populations. The variability in health status among older adults is pertinent. Those with robust health are more likely to tolerate and derive benefit from many therapies when compared with those who have more complex health including frailty. Age- and/or frailty-stratified data to help clarify these relationships are sparse. In this Perspective, current recommendations for modifying ASCVD risk are described with a review of the pertinent literature that guides their application in older adults. A pragmatic approach to the treatment of ASCVD risk factors in older adults with diabetes is presented.

Abstract
The development of coronary revascularization has dramatically improved early cardiovascular outcomes in patients with acute coronary syndrome (ACS). However, patients who have experienced myocardial infarction (MI) are at high risk of recurrence of cardiovascular events compared with those who are healthy or have stable coronary artery disease. Acute coronary events induce further inflammatory responses and plaque vulnerability in either a coronary culprit or whole vessels. The majority of data have supported the importance of coronary risk management to prevent secondary events. Dyslipidemia is common and one of the therapeutic targets in patients with ACS. Statins can reduce coronary plaque burden and lower the risk of cardiovascular death, recurrent MI, stroke, and coronary revascularization in patients with ACS. Growing evidence from clinical trials and meta-analyses supports early, intensive, and continuous therapy with statins in patients with ACS. Statins are accepted worldwide as the first-line lipid-lowering therapy as guidelines recommend. However, some patients do not reach the target level of low-density lipoprotein cholesterol by statins alone or are contra-indicated for statins. Recently, several clinical trials showed the further benefit of ezetimibe combined with statins on cardiovascular outcomes and coronary plaque regression in patients with ACS. In addition, proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, novel and powerful lipid-lowering agents, have been developed and used in clinical settings. In this review, we summarize the present statin therapy, and refer to ezetimibe and PCSK9 as novel or additional non-statin strategies in the management of ACS.

Abstract
BACKGROUND Fibrates are effective for modifying atherogenic dyslipidaemia, and particularly for lowering serum triglycerides. However, evidence that fibrates reduce mortality and morbidity associated with cardiovascular disease (CVD), or overall mortality and morbidity, in the primary prevention of CVD is lacking. OBJECTIVES This Cochrane Review and meta-analysis aimed to evaluate the clinical benefits and harms of fibrates versus placebo or usual care or fibrates plus other lipid-modifying drugs versus other lipid-modifying drugs alone for the primary prevention of cardiovascular disease (CVD) morbidity and mortality. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (Ovid), Embase (Ovid), CINAHL (EBSCO), and Web of Science (all from inception to 19 May 2016). We searched four clinical trial registers (last searched on 3 August 2016) with the help of an experienced professional librarian. We searched the databases to identify randomised controlled trials (RCTs) evaluating the clinical effects of fibrate therapy in the primary prevention of CVD events. We did not impose any language restrictions. SELECTION CRITERIA We aimed to include all RCTs comparing the effects of fibrate monotherapy versus placebo or usual care, or fibrates plus other lipid-modifying drugs versus other lipid-modifying drugs alone. Included studies had a follow-up of at least six months for the primary prevention of CVD events. We excluded trials with clofibrate, because it was withdrawn from the market in 2002. DATA COLLECTION AND ANALYSIS Two review authors independently screened titles and abstracts for potential study inclusion. Two review authors independently retrieved the full-text papers and extracted data. Disagreements were resolved by consensus. We calculated risk ratios (RRs) and accompanying 95% confidence intervals (CIs) for aggregate data on primary and secondary outcomes. We tested for heterogeneity with the Cochrane Q-test and used the I2 statistic to measure inconsistency of treatment effects across studies. Using the GRADE approach, we assessed the quality of the evidence and used the GRADE profiler software (GRADEpro GDT) to import data from Review Manager 5 to create 'Summary of findings' tables. MAIN RESULTS We identified six eligible trials including 16,135 individuals. The mean age of trial populations varied across trials; between 47.3 and 62.3 years. Four trials included individuals with diabetes mellitus type 2 only. The mean treatment duration and follow-up of participants across trials was 4.8 years. We judged the risks of selection and performance bias to be low; risks of detection bias, attrition bias, and reporting bias were unclear. Reporting of adverse effects by included trials was very limited; that is why we used discontinuation of therapy due to adverse effects as a proxy for adverse effects. Patients treated with fibrates had a reduced risk for the combined primary outcome of CVD death, non-fatal myocardial infarction, or non-fatal stroke compared to patients on placebo (risk ratio (RR) 0.84, 95% confidence interval (CI) 0.74 to 0.96; participants = 16,135; studies = 6; moderate-quality of evidence). For secondary outcomes we found RRs for fibrate therapy compared with placebo of 0.79 for combined coronary heart disease death or non-fatal myocardial infarction (95% CI 0.68 to 0.92; participants = 16,135; studies = 6; moderate-quality of evidence); 1.01 for overall mortality (95% CI 0.81 to 1.26; participants = 8471; studies = 5; low-quality of evidence); 1.01 for non-CVD mortality (95% CI 0.76 to 1.35; participants = 8471; studies = 5; low-quality of evidence); and 1.38 for discontinuation of therapy due to adverse effects (95% CI 0.71 to 2.68; participants = 4805; studies = 3; I2 = 74%; very low-quality of evidence). Data on quality of life were not available from any trial. Trials that evaluated fibrates in the background of statins (2 studies) showed no benefits in preventing cardiovascular events. AUTHORS' CONCLUSIONS Moderate-quality evidence suggests that fibrates lower the risk for cardiovascular and coronary events in primary prevention, but the absolute treatment effects in the primary prevention setting are modest (absolute risk reductions < 1%). There is low-quality evidence that fibrates have no effect on overall or non-CVD mortality. Very low-quality evidence suggests that fibrates are not associated with increased risk for adverse effects.

Abstract
About one-half of individuals with an acute myocardial infarction have a low-density lipoprotein cholesterol level of less than 100 mg/dL at the time of occurrence, but remain at risk for recurrent events. This residual risk is likely mediated by multiple factors, including burden of atherosclerosis, residual dyslipidemia, nonlipid risk factors, and suboptimal implementation of lifestyle therapy and evidence-based pharmacologic therapy. This article reviews management options for this high-risk population.

Abstract
Hypertriglyceridemia is an important risk factor associated with insulin resistance and β-cell dysfunction. This study investigated the effects of hypertriglyceridemia and fenofibrate treatment on insulin sensitivity and β-cell function in subjects with normal glucose tolerance. A total of 1974 subjects with normal glucose tolerance were divided into the normal TG group (NTG group, n = 1302) and hypertriglyceridemia group (HTG group, n = 672). Next, 92 patients selected randomly from 672 patients with hypertriglyceridemia were assigned to a 24-week fenofibrate treatment. The HTG group had increased waist circumference (WC), body mass index (BMI), homeostasis model assessment of insulin resistance (HOMA-IR), and homeostasis model assessment of β-cell function (HOMA-β) and decreased high-density lipoprotein cholesterol (HDL-C) compared with the NTG group (all P < 0.01). The 24-week fenofibrate treatment significantly decreased the WC, BMI, TG, HOMA-IR, and HOMA-β levels and increased the HDL-C levels in the patients with hypertriglyceridemia (WC, BMI, and HOMA-IR: P < 0.05; TG, HDL-C, and HOMA-β: P < 0.01). The fenofibrate treatment significantly alleviated insulin resistance and reduced the secreting load of β-cells in the hypertriglyceridemia patients with normal glucose tolerance.

Abstract
AIMS Apolipoprotein A-1 (ApoA-1), based on epidemiology, is inversely associated with cardiovascular (CV) events. Human carriers of the ApoA-1 Milano variant have a reduced incidence of CV disease. Regression of atherosclerotic plaque burden was previously observed on intravascular ultrasound (IVUS) with ETC-216, a predecessor of MDCO-216. MDCO-216, a complex of dimeric ApoA-1 Milano and 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine, is being developed to reduce atherosclerotic plaque burden and CV events. We investigated the efficacy and safety of a single infusion of MDCO-216 in healthy volunteers and in patients with coronary artery disease (CAD). METHODS AND RESULTS Twenty-four healthy volunteers and 24 patients with documented CAD received a 2-h infusion of MDCO-216 in a randomized, placebo controlled, single ascending dose study. Five cohorts of healthy volunteers and four cohorts of CAD patients received ApoA-1 Milano doses ranging from 5 to 40 mg/kg. Subjects were followed for 30 days. Dose-dependent increases in ApoA-1, phospholipid, and pre-beta 1 HDL and decreases in ApoE were observed. Prominent and sustained increases in triglyceride, and decreases in HDL-C, endogenous ApoA-1 and ApoA-II occurred at doses >20 mg/kg and profound increases in ABCA1-mediated cholesterol efflux were observed. Other lipid and lipoprotein parameters were generally unchanged. MDCO-216 was well tolerated. CONCLUSIONS MDCO-216-modulated lipid parameters profoundly increased ABCA1-mediated cholesterol efflux and was well tolerated. These single-dose data support further development of this agent for reducing atherosclerotic disease and subsequent CV events.

Abstract
BACKGROUND Fibrates are a class of drugs characterised by mainly lowering high triglyceride, raising high-density lipoprotein (HDL) cholesterol, and lowering the small dense fraction of low-density lipoprotein (LDL) cholesterol. Their efficacy for secondary prevention of serious vascular events is unclear, and to date no systematic review focusing on secondary prevention has been undertaken. OBJECTIVES To assess the efficacy and safety of fibrates for the prevention of serious vascular events in people with previous cardiovascular disease (CVD), including coronary heart disease and stroke. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL; Issue 9, 2014) on the Cochrane Library, MEDLINE (OVID, 1946 to October week 1 2014), EMBASE (OVID, 1980 to 2014 week 41), the China Biological Medicine Database (CBM) (1978 to 2014), the Chinese National Knowledge Infrastructure (CNKI) (1979 to 2014), Chinese Science and Technique Journals Database (VIP) (1989 to 2014). We also searched other resources, such as ongoing trials registers and databases of conference abstracts, to identify further published, unpublished, and ongoing studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) in which a fibrate (for example gemfibrozil, fenofibrate) was compared with placebo or no treatment. We excluded RCTs with only laboratory outcomes. We also excluded trials comparing two different fibrates without a placebo or no-treatment control. DATA COLLECTION AND ANALYSIS Two review authors independently selected trials for inclusion, assessed risk of bias, and extracted the data. We contacted authors of trials for missing data. MAIN RESULTS We included 13 trials involving a total of 16,112 participants. Eleven trials recruited participants with history of coronary heart disease, two trials recruited participants with history of stroke, and one trial recruited participants with a mix of people with CVD. We judged overall risk of bias to be moderate. The meta-analysis (including all fibrate trials) showed evidence for a protective effect of fibrates primarily compared to placebo for the primary composite outcome of non-fatal stroke, non-fatal myocardial infarction (MI), and vascular death (risk ratio (RR) 0.88, 95% confidence interval (CI) 0.83 to 0.94; participants = 16,064; studies = 12; I(2) = 45%, fixed effect). Fibrates were moderately effective for preventing MI occurrence (RR 0.86, 95% CI 0.80 to 0.93; participants = 13,942; studies = 10; I(2) = 24%, fixed effect). Fibrates were not effective against all-cause mortality (RR 0.98, 95% CI 0.91 to 1.06; participants = 13,653; studies = 10; I(2) = 23%), death from vascular causes (RR 0.95, 95% CI 0.86 to 1.05; participants = 13,653; studies = 10; I(2) = 11%, fixed effect), and stroke events (RR 1.03, 95% CI 0.91 to 1.16; participants = 11,719; studies = 6; I(2) = 11%, fixed effect). Excluding clofibrate trials, as the use of clofibrate was discontinued in 2012 due to safety concerns, the remaining class of fibrates were no longer effective in preventing the primary composite outcome (RR 0.90, 95% CI 0.79 to 1.03; participants = 10,320; studies = 7; I(2) = 50%, random effects). However, without clofibrate data, fibrates remained effective in preventing MI (RR 0.85, 95% CI 0.76 to 0.94; participants = 8304; studies = 6; I(2) = 47%, fixed effect). There was no increase in adverse events with fibrates compared to control. Subgroup analyses showed the benefit of fibrates on the primary composite outcome to be consistent irrespective of age, gender, and diabetes mellitus. AUTHORS' CONCLUSIONS Moderate evidence showed that the fibrate class can be effective in the secondary prevention of composite outcome of non-fatal stroke, non-fatal MI, and vascular death. However, this beneficial effect relies on the inclusion of clofibrate data, a drug that was discontinued in 2002 due to its unacceptably large adverse effects. Further trials of the use of fibrates in populations with previous stroke and also against a background treatment with statins (standard of care) are required.

Abstract
Despite the clinical benefits of lowering levels of low-density lipoprotein cholesterol, many patients continue to experience cardiovascular events. This residual risk suggests that additional risk factors require aggressive modification to result in more effective prevention of cardiovascular disease. Hypertriglyceridemia has presented a considerable challenge with regard to understanding its role in the promotion of cardiovascular risk. Increasing evidence has established a clear causal role for elevated triglyceride levels in vascular risk. As a result, there is increasing interest in the development of specific therapeutic strategies that directly target hypertriglyceridemia. This has seen a resurgence in the use of omega-3 fatty acids for the therapeutic lowering of triglyceride levels. The role of these agents and other emerging strategies to reduce triglyceride levels in order to decrease vascular risk are reviewed.

Abstract
Peroxisome proliferator-activated receptors (PPARs) are transcription factors that belong to the superfamily of nuclear hormone receptors and regulate the expression of several genes involved in metabolic processes that are potentially linked to the development of some diseases such as hyperlipidemia, diabetes, and obesity. One type of PPAR, PPAR-α, is a transcription factor that regulates the metabolism of lipids, carbohydrates, and amino acids and is activated by ligands such as polyunsaturated fatty acids and drugs used to treat dyslipidemias. There is evidence that genetic variants within the PPARα gene have been associated with a risk of the development of dyslipidemia and cardiovascular disease by influencing fasting and postprandial lipid concentrations; the gene variants have also been associated with an acceleration of the progression of type 2 diabetes. The interactions between genetic PPARα variants and the response to dietary factors will help to identify individuals or populations who can benefit from specific dietary recommendations. Interestingly, certain nutritional conditions, such as the prolonged consumption of a protein-restricted diet, can produce long-lasting effects on PPARα gene expression through modifications in the methylation of a specific locus surrounding the PPARα gene. Thus, this review underlines our current knowledge about the important role of PPAR-α as a mediator of the metabolic response to nutritional and environmental factors.

Abstract
Coronary artery disease (CAD) in patients with type 2 diabetes mellitus (T2DM) is associated with increased immediate and long-term mortality compared with patients without T2DM. The amplified incidence of CAD stems partly from the aggregation of multiple risk factors, such as obesity, dyslipidemia, and hypertension, which occur in this population. In addition, there appear to be increased forces at play at the molecular and vascular levels in these individuals, which is evidenced by the increased thrombosis and inflammation that is seen in those with diabetic atherosclerosis. Hence, there is a growing need to emphasize early and vigilant risk factor management in patients with T2DM to help reduce their burden of cardiovascular-related mortality. In this article, we review the primary and secondary prevention measures as well as the management of CAD in patients with T2DM.

Abstract
OBJECTIVE The most prevalent dyslipidemias in Mexico are low high-density lipoprotein (HDL) and high triglyceride (TG) levels. Hypertriglyceridemia (HTG) has been considered an independent risk factor for cardiovascular disease (CVD). The aim of this study was to evaluate the efficacy of rosuvastatin (RSV) in reducing TG levels in Mexican patients. METHODS A randomized, double-blind, double-dummy, parallel-group, placebo-controlled, multicenter, phase IV study was conducted. Patients were of both genders, ≥ 18 years old, with basal TG levels between 200 and 800 mg/dl, LDL levels ≤ 190 mg/dl. Patients were randomized to receive rosuvastatin 10 mg (Group 1), 20 mg (Group 2) or placebo (Group 3) once daily for 8 weeks. Primary efficacy was TG level; secondary efficacy was non-HDL; HDL, low-density lipoprotein (LDL), total cholesterol (TC), Apo (apolipoprotein) A1, and ApoB. Safety data were evaluated up to 30 days after the last dose of medication. The Mann-Whitney U-test was performed to contrast each RSV groups against placebo; p < 0.05 was considered significant. Trial registry number is NCT00473655. RESULTS A total of 334 patients were randomized: Group 1 = 111, Group 2 = 112, and Group 3 = 111. Basal TG median value levels were 278 mg/dl, 266 mg/dl, 279 mg/dl with median reduction (MdR) at 8 weeks of 26.6%, 32.19% and 7.58%, respectively, (Group 1 vs. Group 3 p = 0.002, and Group 2 vs. Group 3 p < 0.0001). Basal non-HDL values were 179 mg/dl, 180 mg/dl and 179 mg/dl with a MdR of 27%, 32% and 8%, respectively (Group 1 vs. Group 3 p < 0.0001, and Group 2 vs. Group 3 p < 0.0001); basal LDL vales were 130 mg/dl, 130 mg/dl and 127 mg/dl with MdR 35%, 44% and -4% (Group 1 vs. Group 3 p < 0.0001, Group 2 vs. Group 3 p < 0.0001); basal ApoB values were 114 mg/dl, 115 mg/dl and 110.5 mg/dl with MdR 25%, 33% and -0.5% (Group 1 vs. Group 3 p < 0.0001, Group 2 vs. Group 3 p < 0.001). CONCLUSION Rosuvastatin 10 and 20 mg/day significantly reduced triglycerides and improved atherogenic lipid profile in HTG Mexican patients. The main limitation was the short follow-up time period.
