Relationship of Sulfatides Physiological Function and Peroxisome Proliferator-Activated Receptor α. Neurochem Res 2023; 48:2059-2065. [PMID: 36879104 DOI: 10.1007/s11064-023-03895-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Revised: 02/09/2023] [Accepted: 02/14/2023] [Indexed: 03/08/2023]
Abstract
Sulfatides are unique sphingolipids present in the serum and the plasma membrane. Sulfatides exert important functions in a number of systems in the human body, including the nervous, immune, cardiovascular, and coagulation systems.Furthermore, it is closely related to tumor occurrence, development, and metastasis. Peroxisome proliferators-activated receptor α (PPARα) is a class of the nuclear receptor superfamily of transcription factors, which is a potential regulator of sulfatides. This review not only summarizes the current knowledge on the physiological functions of sulfatides in various systems, but also discusses the possible PPARα regulatory mechanisms in sulfatide metabolism and functions. The results of the present analysis provide deep insights and further novel ideas for expanding the research on the physiological function and clinical application of sulfatides.

[PMID: 35803336 DOI: 10.1016/j.cca.2022.06.030] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 06/16/2022] [Accepted: 06/27/2022] [Indexed: 11/03/2022]
Abstract
PURPOSE Rheumatoid arthritis (RA) patients have accelerated atherosclerosis (AS) leading to excess cardiovascular morbidity and mortality, but traditional risk factors for cardiovascular disease (CVD) are invalid to explain the problem. Sulfatides, as major components of serum lipoproteins, are synthesized in the liver. These molecules are reported to play an important role in the development of AS, thrombogenesis, and inflammation. However, it is unclear whether sulfatides are responsible for such issue. To elucidate the possible association between serum sulfatide and the accelerated progress of AS, evaluated by carotid intima-media thickness (CIMT), and ascertain the related mechanism underlying the correlation in RA cases. METHODS We performed an observational study of 144 patients with RA and 120 sex and age-matched controls. Meanwhile, 107 patients (of the 144 RA patients enrolled at baseline) were invited to undergo a second measurement after 12 months. Serum sulfatide levels of all the enrolled subjects were quantified by mass spectrometry after they were converted into lysosulfatides (LS), and then calculated as the sum of the levels of seven LS molecular species. Serum oxidative stress marker, malondialdehyde (MDA) was detected by ELISA. We subsequently statistically analyzed the causalities between carotid AS and clinical parameters, and the association of serum sulfatide with other variables. Multivariable logistic regression analysis was finally employed by taking all factors to identify independent determinant for carotid atherosclerotic plaque and serum sulfatide level. RESULTS A gradual declined trend in serum sulfatide levels was observed in control subjects, non-plaque group, and the plaque group (8.56 ± 1.37 nmol/mL, 5.63 ± 1.57 nmol/mL, 3.18 ± 1.32 nmol/mL, respectively, p < 0.01), along with an increased value of CIMT (0.63 ± 0.07 mm, 0.92 ± 0.14 mm, 1.43 ± 0.22 mm, respectively, p < 0.01). Meanwhile, a negative linear correlation between CIMT and serum sulfatide was further confirmed by Spearman's analysis (r = -0.622, p < 0.01). Eventually, multivariate logistic regression analysis identified serum MDA as the only independent factor for the abnormal level of serum sulfatide, and serum sulfatide was detected as a significant protective factor for the occurrence of carotid plaques in RA cases (p < 0.01), which was confirmed repeatedly by our cross-sectional and longitudinal studies. CONCLUSION Excessive abnormal levels of oxidative stress decreased serum sulfatide levels, followed by a high occurrence of AS in RA patients. Serum sulfatide level might be useful as a predictor (biomarker) for the progression of AS in RA cases.

Serum Sulfatide Levels as a Biomarker of Active Glomerular Lesion in Patients with Anti-Neutrophil Cytoplasmic Antibody-Associated Vasculitis: A Single Center Pilot Study. J Clin Med 2022; 11:jcm11030762. [PMID: 35160215 PMCID: PMC8836560 DOI: 10.3390/jcm11030762] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2021] [Revised: 01/16/2022] [Accepted: 01/28/2022] [Indexed: 11/16/2022] Open
Abstract
Sulfatides are glycosphingolipids that are associated with coagulation and platelet aggregation. Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) activates platelet function and often leads to thrombotic complications. These facts suggest an association between serum sulfatides and AAV. We aimed to clarify the significance of serum sulfatide levels in patients with AAV. We conducted a retrospective, single-center, observational pilot study that included 35 patients who developed AAV and 10 control patients who were candidates for living-donor kidney transplantation. We compared serum sulfatide levels between the control and AAV patients. We analyzed the differences in serum sulfatide levels among four classes (focal, crescentic, mixed, and sclerotic class) of glomerular lesions that were categorized by histopathologic classification of ANCA-associated glomerulonephritis. Serum sulfatide levels in patients with AAV were significantly lower than those in the controls. Serum sulfatide levels were significantly different between the four classes. Additionally, serum sulfatide levels in the crescentic class were significantly lower than those in the other classes. Serum sulfatide levels were significantly correlated with albumin, cholesterol, C-reactive protein, and pentraxin 3. In conclusion, serum sulfatide levels are significantly correlated with inflammation, reflecting crescentic glomerulonephritis, which is an active glomerular lesion in AAV patients.

Peroxisome proliferator-activated receptor α attenuates high-cholesterol diet-induced toxicity and pro-thrombotic effects in mice. Arch Toxicol 2018; 93:149-161.

Abstract
Peroxisome proliferator-activated receptor α (PPARα) is involved in the regulation of fatty acid and cholesterol metabolism. A high-cholesterol (HC) diet increases the risk of developing cardiovascular diseases (CVD); however, it is unclear whether the toxic effects of cholesterol involve changes in thrombotic factor expression, and whether PPARα is necessary for such effects. To investigate this possibility, we fed a HC diet to wild-type (WT) and Ppara-null mice and measured cholesterol and triglyceride contents, liver histology, serum/plasma levels of coagulation factors, hepatic expression of the coagulation factors, liver/serum sulfatide levels, hepatic sulfatide metabolism, hepatic expression of lipid transporters, and hepatic oxidative stress and its relating enzymes. In Ppara-null mice, the HC diet caused triglyceride accumulation and exacerbated inflammation and oxidative stress in liver, increased levels of coagulation factors, including tissue factor, plasminogen activator inhibitor-1 and carboxypeptidase B2 in blood and liver, and decreased levels of anti-thrombotic sulfatides in serum and liver. These changes were much less marked in WT mice. These findings imply that cholesterol overload exerts its toxic effects at least in part by enhancing thrombosis, secondary to abnormal hepatic lipid metabolism, inflammation, and oxidative stress. Moreover, we reveal for the first time that PPARα can attenuate these toxic effects by transcriptional regulation of coagulation factors and sulfatides, in addition to its known effects of controlling lipid homeostasis and suppressing inflammation and oxidative stress. Therapies aimed at activating PPARα might prevent HC diet-induced CVD through modulating various pro- and anti-thrombotic factors.

Abstract
AIM The impact of mild drinking habit (less than 20 g/d of ethanol) on the clinical course of non-alcoholic fatty liver disease (NAFLD) has not been determined. We examined the influence of a mild drinking habit on liver carcinogenesis from NAFLD.
METHODS A total of 301 patients who had been diagnosed as having NAFLD by liver biopsy between 2003 and 2016 [median age: 56 years, 45% male, 56% with non-alcoholic steatohepatitis, 26% with advanced fibrosis (F3-4)] were divided into the mild drinking group with ethanol consumption of less than 20 g/d (mild drinking group, n = 93) and the non-drinking group (n = 208). Clinicopathological features at the time of liver biopsy and factors related to hepatocellular carcinoma (HCC) occurrence were compared between the groups.
RESULTS We observed significant differences in male prevalence (P = 0.01), platelet count (P = 0.04), and gamma-glutamyl transpeptidase (P = 0.02) between the test groups. Over 6 years of observation, the HCC appearance rate was significantly higher in the mild drinking group (6.5% vs 1.4%, P = 0.02). Multivariate survival analysis using Cox’s regression model revealed that hepatic advanced fibrosis (F3-4) (P < 0.01, risk ratio: 11.60), diabetes mellitus (P < 0.01, risk ratio: 89.50), and serum triglyceride (P = 0.04, risk ratio: 0.98) were factors significantly related to HCC in all NAFLD patients, while the effect of a drinking habit was marginal (P = 0.07, risk ratio: 4.43). In patients with advanced fibrosis (F3-4), however, a drinking habit (P = 0.04, risk ratio: 4.83), alpha-fetoprotein (P = 0.01, risk ratio: 1.23), and diabetes mellitus (P = 0.03, risk ratio: 12.00) were identified as significant contributors to HCC occurrence.
CONCLUSION A mild drinking habit appears to be a risk factor for hepatocarcinogenesis in NAFLD patients, especially those with advanced fibrosis.

Abstract
Alkaline ceramidases (ACERs) are a class of ceramidases (CDase), and three types including ACER1, ACER2, and ACER3 have been identified. ACERs can catalyze the hydrolysis of ceramide (Cer) to generate sphingosine (SPH), and SPH is further phosphorylated to produce sphingosine-1-phosphate (S1P). Cer, SPH, and S1P are several important bioactive metabolites of sphingolipids. ACERs regulate the balance of Cer, SPH and S1P, and thus mediate cell proliferation, differentiation, survival, apoptosis, and tumor initiation and development. This article reviews the biochemical properties and biological function of ACER and its role in liver cancer.

Abstract
Sulfatides, a type of glycosphingolipid, are associated with carcinogenesis. Peroxisome proliferator-activated receptor α (PPARα) is involved in the regulation of sulfatide metabolism as well as in cancer development. We previously reported that transgenic (Tg) mice expressing hepatitis C virus core protein (HCVcp) exhibited age-dependent PPARα activation and carcinogenesis in liver. However, the metabolism of sulfatides in hepatocellular carcinoma is unknown. To examine the relationship between sulfatide metabolism, carcinogenesis, HCVcp, and PPARα, age-dependent changes of these factors were examined in HCVcpTg, PPARα inhibitor-treated HCVcpTg, and non-Tg mice. The sulfatide content in liver, the hepatic expression of two key enzymes catalyzing the initial and last reactions in sulfatide synthesis, the hepatic expression of known sulfatide-transferring protein, oxidative stress, and hepatic PPARα expression and its activation were age-dependently increased in HCVcpTg mice. The increased synthesis and accumulation of sulfatides and PPARα activation were significantly enhanced in liver cancer lesions. These changes were attenuated by PPARα inhibitor treatment and not observed in non-Tg mice. These results suggest that HCVcp-induced age-dependent PPARα activation increases synthesis of sulfatides and the resulting sulfatide accumulation affects HCV-related liver cancer. The monitoring of hepatic sulfatide content and the modulation of sulfatide generation by intervention using a PPARα inhibitor might be useful for the prediction and prevention of HCV-related hepatocarcinogenesis, respectively.

Abstract
BACKGROUND Heavy ethanol consumption is widely accepted as a risk for ischemic stroke. The molecular mechanisms of ethanol-induced brain injury have not been fully understood. AIM This study aims to find out the mechanism of the ischemic cerebral injury. METHODS We used Sprague-Dawley rats with transient middle cerebral artery occlusion for acute experiment and stroke-prone spontaneously hypertensive rats for long-term experiment in vivo, and oxygen-glucose deprivation model in vitro to define a detrimental effect of different doses of ethanol on ischemic stroke injury. We also used mitochondrial aldehyde dehydrogenase 2 knockdown/overexpression or inhibitor/activator to investigate mechanism of the adverse effects of ethanol. RESULTS High-dose ethanol (36% of calorie derived from ethanol) significantly increased the infarct size in rats (P < 0·01) and decreased the survival time of stroke-prone spontaneously hypertensive rats by about 20%. Six-week treatment with high-dose ethanol changed a distribution of isoelectric point of aldehyde dehydrogenase 2 and inhibited aldehyde dehydrogenase 2 activity in brain. High dose of ethanol increased the cerebral acetaldehyde level, and increased 4-hydroxy-2-nonenal and malondialdehyde in serum of rats with middle cerebral artery occlusion. The activator of aldehyde dehydrogenase 2, Alda-1 abolished neuronal cells death and ischemic injury induced by ethanol and the inhibitor reversed the injurious effects. An overexpression of aldehyde dehydrogenase 2 completely abolished the increased infarct size and neurological deficit score by ethanol. Conversely, knockdown of aldehyde dehydrogenase 2 increased the infarct size and exaggerated the cerebral injury induced by ethanol. CONCLUSIONS High concentrations of ethanol aggravate cerebral injury by inhibiting of aldehyde dehydrogenase 2 and inducing excess accumulation of aldehydes.

Abstract
Neutrophils die by apoptosis following activation and uptake of microbes or enter apoptosis spontaneously at the end of their lifespan if they do not encounter a pathogen. Here we report that sulfatides or sulfatides-treated Salmonella Typhimurium bacteria accelerated human neutrophil apoptosis. Neutrophil apoptosis was examined by flow cytometry. Sulfatides caused prominent increase in percentage of apoptotic cells after 2.5 hrs of incubation. Salmonella Typhimurium bacteria by themselves did not affect the basal level of apoptosis in neutrophil population. When neutrophils were added to S. Typhimurium "opsonized" by sulfatides, apoptotic index significantly increased, whereas the number of phagocyting cells was not influenced. Sulfatides' proapoptotic effect was strongly dependent on the activity of β-galactosidase; inhibition of this enzyme impaired its potency to accelerate apoptosis. These data support the mechanism of neutrophil apoptosis triggering based on sulfatides' ability to accumulate in intracellular compartments and mediate successive increase in ceramide content resulting from β-galactosidase activity.
