Abstract
OBJECTIVE Regulator of calcineurin 1 (RCAN1) controls plasticity of the nervous system and depressive conditions by regulating brain-derived neurotropic factor (BDNF) and plays a crucial role in neural and cardiac pathways. The apolipoprotein E gene (ApoE) is a robust risk factor for progression of Alzheimer's disease. A fatty diet is considered detrimental for metabolic disorders, such as obesity and cardiovascular diseases. METHODS We examined the neuronal and cardiac protective roles of RCAN1 in ApoE-/- mice that were fed a high- or low-fat diet with and without voluntary movement for 3 months. Organ weights, laboratory data, histology, RNA expression, and behavior were examined. RESULTS A high-fat diet with exercise improved depressive function, as examined by the forced swimming test, and RCAN1 mRNA expression was induced in the hippocampus. A low-fat diet with exercise resulted in a reduced body weight, higher heart weight/body weight ratio, and lower circulating triglyceride levels compared with a low-fat diet without exercise. RCAN1 mRNA expression was increased in cardiomyocytes in ApoE-/- mice. CONCLUSIONS The combination of a high-fat diet and exercise might reduce depressive function, whereas a low-fat diet with exercise leads to cardioprotection. Induction of RCAN1 expression might affect neuroplasticity and cardiac function.

Abstract
The apolipoproteins (APOs) of human very low-density lipoprotein (VLDL) were investigated by an optimized cyclodextrin-micellar electrokinetic chromatography (CD-MEKC) method. The separation buffer consisted of 20 mM sodium phosphate, 40 mM bile salts (50% sodium cholate and 50% sodium deoxycholate), 25 mM carboxymethyl-β-cyclodextrin (CM-β-CD) (pH 7.0). For CD-MEKC separation, a sample injection time of 12 s, a separation voltage of 15 KV, and a capillary temperature of 15°C were chosen. The optimal CD-MEKC method showed good resolution and repeatability for VLDL APOs. Identification and quantitation of VLDL APOs CI, CIII, and E were based on comparison with human APO standards. Good linear relationships with correlation coefficient (R2 ) 0.99 were obtained for APOs CI, CIII, and E standards. For these three APOs, the linear ranges were within 0.01-0.54 mg/mL, and the concentration limits of detection (LODs) were lower than 0.02 mg/mL. Moreover, VLDL APOs from four uremic patients and four healthy subjects were compared. The uremic and healthy CD-MEKC profiles showed dramatic difference. The levels of APO CIII were significantly higher for two patients, and the level of APO E was significantly higher for one patient. This study might be helpful for following the disease development of uremia and cardiovascular disease (CVD) in the future.

Apolipoprotein E gene polymorphism and renal function are associated with apolipoprotein E concentration in patients with chronic kidney disease. Lipids Health Dis 2019; 18:60. [PMID: 30851738 PMCID: PMC6408819 DOI: 10.1186/s12944-019-1003-x] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2018] [Accepted: 03/01/2019] [Indexed: 12/02/2022] Open
Abstract
Background Chronic kidney disease (CKD) associates with complex lipoprotein disturbances resulting in high cardiovascular risk. Apolipoprotein E (APOE) is a polymorphic protein with three common isoforms (E2; E3; E4) that plays a crucial role in lipoprotein metabolism, including hepatic clearance of chylomicrons and very low-density lipoprotein (VLDL) remnants, and reverse cholesterol transport. It demonstrates anti-atherogenic properties but data concerning the link between polymorphism and level of APOE in CKD patients are inconclusive. The aim of our research was to assess the relationship between APOE gene polymorphism and APOE concentration and its redistribution among lipoproteins along with CKD progression. Methods 90 non-dialysed CKD patients were included into the study. Real time PCR was used for APOE genotyping. APOE level was measured in serum and in isolated lipoprotein fractions (VLDL; IDL + HDL; HDL). Kidney function was assessed using eGFR CKD-EPI formula. Results The population was divided into three APOE genotype subgroups: E2(ε2ε3), E3(ε3ε3) and E4(ε3ε4). The highest APOE level was observed for the E2 subgroup (p < 0.001). APOE concentration positively correlated with eGFR value in the E2 subgroup (r = 0.7, p < 0.001) but inversely in the E3 subgroup (r = − 0.29, p = 0.02).). A lower concentration of APOE in the E2 subgroup was associated with its diminished contents in HDL and IDL + LDL particles. In the E3 subgroup, the higher concentration of APOE was related to the increased number of non-HDL lipoproteins. Conclusion In patients with CKD, APOE genotype as well as renal function are associated with the concentration of APOE and its redistribution among lipoprotein classes.

Abstract
Arsenic is one of the most widespread global environmental toxicants associated with endemic poisoning. ATP-binding cassette (ABC) proteins are transmembrane channels that transport and dispose of lipids and metabolic products across the plasma membrane. The majority of ABC family members (including ABCB1 and ABCC1) are reported to play a role in the development of arsenic and drug resistance in mammals. Previously, we established a human arsenic-resistant ECV-304 (AsRE) cell line and identified ABCA1 as a novel arsenic resistance gene. In the current study, we further investigated the potential contribution of ABCA1, ABCB1, and ABCC1 to arsenic resistance through measurement of survival rates and arsenic accumulation in AsRE cells with RNA interference. The arsenic resistance capacity of ABCC1 was the strongest among the three genes, while those of ABCA1 and ABCB1 were similar. Double or triple gene knockdown of ABCA1, ABCB1, and ABCC1 via RNA interference led to a decrease significant in arsenic resistance when ABCA1/ABCB1 or ABCB1/ABCC1 were simultaneously silenced. Interestingly, no differences were evident between cells with ABCA1/ABCC1 and ABCC1 only knockdown. Our findings suggest that ABCA1 and ABCB1 proteins display similar arsenic resistance capabilities and possibly coordinate to promote arsenic resistance in AsRE cells.

Long-term effects of low-dose mouse liver irradiation involve ultrastructural and biochemical changes in hepatocytes that depend on lipid metabolism. RADIATION AND ENVIRONMENTAL BIOPHYSICS 2018; 57:123-132. [PMID: 29470638 DOI: 10.1007/s00411-018-0734-9] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/31/2017] [Accepted: 02/16/2018] [Indexed: 06/08/2023]
Abstract
The aim of the study was to investigate long-term effects of radiation on the (ultra)structure and function of the liver in mice. The experiments were conducted on wild-type C57BL/6J and apolipoprotein E knock-out (ApoE-/-) male mice which received a single dose (2 or 8 Gy) of X-rays to the heart with simultaneous exposure of liver to low doses (no more than 30 and 120 mGy, respectively). Livers were collected for analysis 60 weeks after irradiation and used for morphological, ultrastructural, and biochemical studies. The results show increased damage to mitochondrial ultrastructure and lipid deposition in hepatocytes of irradiated animals as compared to non-irradiated controls. Stronger radiation-related effects were noted in ApoE-/- mice than wild-type animals. In contrast, radiation-related changes in the activity of lysosomal hydrolases, including acid phosphatase, β-glucuronidase, N-acetyl-β-D-hexosaminidase, β-galactosidase, and α-glucosidase, were observed in wild type but not in ApoE-deficient mice, which together with ultrastructural picture suggests a higher activity of autophagy in ApoE-proficient animals. Irradiation caused a reduction of plasma markers of liver damage in wild-type mice, while an increased level of hepatic lipase was observed in plasma of ApoE-deficient mice, which collectively indicates a higher resistance of hepatocytes from ApoE-proficient animals to radiation-mediated damage. In conclusion, liver dysfunctions were observed as late effects of irradiation with an apparent association with malfunction of lipid metabolism.

Apolipoprotein E-containing high-density lipoprotein (HDL) modifies the impact of cholesterol-overloaded HDL on incident coronary heart disease risk: A community-based cohort study. J Clin Lipidol 2017; 12:89-98.e2. [PMID: 29217413 DOI: 10.1016/j.jacl.2017.11.003] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2017] [Revised: 11/03/2017] [Accepted: 11/07/2017] [Indexed: 12/11/2022]
Abstract
BACKGROUND Experimental studies have shown that cholesterol-overloaded high-density lipoprotein (HDL) can promote the formation of apolipoprotein E (APOE)-containing HDL, a process correcting the atherogenic function of cholesterol-overloaded HDL. OBJECTIVE The objective of the study was to explore whether APOE-containing HDL can attenuate the defective impact of cholesterol-overloaded HDL on the development of coronary heart disease (CHD) in humans. METHODS We measured APOE-HDL cholesterol (APOE-HDLC), HDL cholesterol (HDLC), and HDL particle number in 1112 participants aged 45 to 74 years at baseline in a community-based cohort study. Cholesterol molecules per HDL particle (HDL-C/P ratio) were calculated as the ratio of HDLC to HDL particle number. The ratio of APOE-HDLC to total HDLC (APOE-HDLC/HDLC ratio) was calculated to assess the relative proportion of APOE-HDLC in total HDLC. RESULTS The HDL-C/P ratio was strongly correlated with APOE-HDLC (partial-r: 0.615). Participants with cholesterol-overloaded HDL (indicated by the highest level of the HDL-C/P ratio) had a high APOE-HDLC/HDLC ratio. Baseline cholesterol-overloaded HDL significantly increased the 10-year risk of incident CHD (hazard ratio = 2.42; 95% confidence interval = 1.06-8.32), but this was attenuated by an increased APOE-HDLC/HDLC ratio. Participants with high HDL-C/P ratio and APOE-HDLC/HDLC ratio had a 42% lower risk, whereas those with a high HDL-C/P ratio and low APOE-HDLC/HDLC ratio had a 2.54-fold higher risk, than those with low HDL-C/P ratio and APOE-HDLC/HDLC ratio after multiple adjustments. CONCLUSION Cholesterol-overloaded HDLs are related with increased APOE-containing HDL species. APOE-containing HDL was found to attenuate the impact of cholesterol-overloaded HDL on increased incident CHD risk, suggesting that APOE-containing HDL may correct the dysfunction of cholesterol-overloaded HDL.

Abstract
PURPOSE The purpose of the present study is to determine if paternal or maternal history of diabetes mellitus (DM) and hypertension (HT) contributes to the prevalence and phenotype of polycystic ovary syndrome (PCOS). METHODS We performed an epidemiologic study about PCOS from four districts in Beijing, China, between 2008 and 2009. Parental histories of DM and HT were collected, and the basic characteristics and serum indices of 123 PCOS patients and 718 non-PCOS controls were tested. RESULTS The prevalence of a parental history of DM and HT was significantly higher in PCOS patients than non-PCOS women (17.1 % vs. 9.2 % and 42.3 % vs. 26.0 %, P < 0.05, respectively). When paternal history was separated from maternal history, only a paternal history of DM and HT reached statistical significance between PCOS and non-PCOS patients (odds ratio (OR) = 3.42, 95 % confidence interval (CI) = 1.69-6.91; OR = 2.50, 95 % CI = 1.58-3.93, respectively). A paternal history of both DM and HT was significantly associated with sex hormone-binding globulin, fasting plasma glucose, and fasting insulin levels, the free androgen index, and the homeostatic model assessment-insulin resistance in PCOS patients (P < 0.05 for all). There was no independent association between maternal history and the clinical or biochemical phenotype of PCOS. CONCLUSIONS PCOS patients with a positive paternal history of both DM and HT have an adverse endocrine and metabolic profile. A paternal history of DM and HT poses a risk to PCOS.
