简介

Receptor for different ligands such as phospholipids, cholesterol ester, lipoproteins, phosphatidylserine and apoptotic cells (PubMed:12016218, PubMed:12519372, PubMed:21226579). Receptor for HDL, mediating selective uptake of cholesteryl ether and HDL-dependent cholesterol efflux (PubMed:26965621). Also facilitates the flux of free and esterified cholesterol between the cell surface and apoB-containing lipoproteins and modified lipoproteins, although less efficiently than HDL. May be involved in the phagocytosis of apoptotic cells, via its phosphatidylserine binding activity (PubMed:12016218). (Microbial infection) Acts as a receptor for hepatitis C virus in hepatocytes and appears to facilitate its cell entry (PubMed:12356718, PubMed:12913001, PubMed:18000990). Binding between SCARB1 and the hepatitis C virus glycoprotein E2 is independent of the genotype of the viral isolate (PubMed:12356718). (Microbial infection) Mediates uptake of M.fortuitum, E.coli and S.aureus. (Microbial infection) Facilitates the entry of human coronavirus SARS-CoV-2 by acting as an entry cofactor through HDL binding.

Comparative analysis of Scarb1 and Cd36 in grass carp (Ctenopharyngodon idellus): Implications for DHA uptake

Article

The polyunsaturated fatty acid docosahexaenoic acid (DHA) significantly influences fish growth and lipid metabolism. Nevertheless, the specific mechanism by which DHA is transported and exerts its effects remains unclear. Scavenger receptor class B type I (SCARB1) is essential for maintaining cellular cholesterol levels and regulating the immune system in mammals, as well as facilitating the uptake of fatty acids (FAs). Another class B scavenger receptor, cluster-determinant 36 (CD36), is involved in promoting the uptake and transport of long-chain fatty acids. However, the molecular characteristics of the grass carp scarb1 gene have not yet been reported, and the potential role of Scarb1 and Cd36 in mediating DHA transport and metabolism remains uncertain. This study aimed to investigate the effects of Scarb1 and Cd36 on DHA transport. Initially, grass carp scarb1-1 and scarb1-2 were cloned. Predictions were made regarding their structural characteristics, including number and presence of transmembrane domains and glycosylation sites. Furthermore, gene structure analysis revealed that scarb1-1 has two additional exons in the 3'-region compared to scarb1-2. The multiple sequence alignment indicated that Scarb1 exhibits conserved motifs and amino acid residues across vertebrates. mRNA expression of scarb1-1 was the highest in the intestine, while scarb1-2 was highest expressed in adipose tissue, with both having lower expression levels in muscle tissue. Scarb1-1 was primarily localized on the cell membrane, whereas Scarb1-2 was found in both the cell membrane and cytoplasm. After overexpression of grass carp Scarb1-1, Scarb1-2, and Cd36 in HEK 293 T cells, DHA incubation showed that only Cd36 significantly increased cellular DHA relative content, suggesting a potential role of Cd36 in DHA transport. These findings will serve as a basis for further research on fatty acid transport in fish.

Paternal trans fatty acid and vitamin E diet affect the expression pattern of androgen signaling pathway genes in the testis of rat offspring

Article

Numerous studies have shown that an improper diet in parents has a negative impact on offspring's health. Furthermore, the negative effects of trans fatty acids (TFA) in maternal diets on fertility and health and their impact on future generations have been documented. However, there is limited research on the negative effects of TFA in paternal diets on male children. The current work used qRT-PCR to investigate the effects of trans fatty acids and vitamin E in the paternal diet on the expression pattern of androgen signaling pathway genes such as STAR, CYP11a1, HSD3B, SRD5a2, and SCARB1 in offspring testes. In this experiment, parental rats were randomly separated into four groups, each with ten father rats, and were fed for eight weeks (60 days) as follows. 1: Standard diet group plus liquid sunflower oil (control). 2: Standard diet group containing trans fatty acids (CTH). 3: The regular diet group received 2.5 times the recommended quantity of vitamin E supplement. 4: Standard diet group with vitamin E and trans fatty acid supplementation (ETH). The testis tissue samples from 35 offspring were then used. Following RNA extraction from tissues and cDNA synthesis, quantitative real-time PCR was used to evaluate the expression levels of androgen signaling pathway genes such as STAR, CYP11A1, HSD3B, SCARB1, and SRD5A2. Our findings showed that the expression of CYP11A1 was considerably reduced in the progeny of paternal rats given ETH compared to the CTH group. The expression levels of the STAR gene were significantly lower in the progeny of paternal rats administered TFA, ETH, and vitamin E compared to the controls. Although the CTH group had lower SCARB1 expression than the other groups, the difference was not statistically significant. Paternal vitamin E consumption substantially affected SRD5A2 expression when compared to offspring of paternal rats fed vitamin E + trans fatty acid or those fed a conventional diet containing trans fatty acid. Furthermore, the vitamin E group showed a statistically significant increase in HSD3B expression compared to the other groups. Bioinformatics analyses, such as protein-protein interaction networks and gene ontology term enrichment, revealed that these genes play roles in lipid biosynthesis, hormone metabolism, male sex differentiation, reproductive development, and steroid biosynthesis. Our data indicate that paternal trans fatty acid consumption influences the expression of particular androgen signaling pathway genes in offspring testis, with vitamin E potentially mitigating some of these effects.

Sirtuin 1-mediated autophagy regulates testosterone synthesis in Leydig cells of piglets

Article

作者: Abouelfetouh, Mahmoud M ; Yu, Lingyun ; He, Yijing ; Ju, Shiqiang ; Li, Qiao ; Zhang, Yanyan ; Zhou, Zhenlei ; Abouelfetouh, Mahmoud M. ; Liu, Chengyin

Testosterone is secreted by Leydig cells (LCs), which play an important physiological role in preserving male secondary sex characteristics, protecting male reproductive function, and establishing the blood-testis barrier. Studies have shown that autophagy is particularly active in LCs; however, its involvement in testosterone synthesis in porcine LCs has not been fully explored. Therefore, this experiment aimed to investigate the influence of autophagy on testosterone secretion in porcine LCs and its potential regulatory mechanism. Our results demonstrated that both testicular autophagy and serum testosterone levels increased in piglets during postnatal development from 4 to 18 weeks. In addition, autophagy was found to degrade the Na⁺/H⁺ exchange regulatory factor 2 (NHERF2), leading to the up-regulation of scavenger receptor class B type 1 (SRB1). This process resulted in increased cholesterol intake and enhanced testosterone production. The observable level of sirtuin 1 (SIRT1) was directly proportional to the level of autophagy. In vitro investigations have shown that SIRT1 can affect the level of autophagy, cholesterol uptake as well as testosterone release. In conclusion, testosterone synthesis during pig development is regulated by SIRT1. SIRT1 mediates the degradation of NHERF2 through autophagy, thereby weakening its negative regulatory effect on the high-density lipoprotein receptor SRB1 in Leydig cells. This process increases cholesterol uptake and enhances testosterone synthesis.

非酒精性脂肪肝影响心血管疾病发生和进展的潜在机理

非酒精性脂肪性肝病(NAFLD)目前是一种日益增长的慢性流行病，并与心血管疾病(CVD)相关。然而，NAFLD如何影响CVD的发生和进展仍然不清楚。2023年9月4日，中山大学凌文华及广州医科大学Xue Hongliang共同通讯在Journal of Hepatology（IF=26）在线发表题为“Hepatic steatosis aggravates atherosclerosis via small extracellular vesicle-mediated inhibition of cellular cholesterol efflux”的研究论文，该研究表明肝脂肪变性通过小细胞外囊泡介导的抑制细胞胆固醇外排加重动脉粥样硬化。来自脂肪变性肝细胞的sEVs通过抑制ABCA在动脉粥样硬化进展中的作用。此外，肝细胞特异性缺失Rab27a可显著改善ApoE-/-小鼠高脂高胆固醇(HFHC)诱导的AS进展。Rab27a是调节sEVs释放的关键GTPase。miRNA深度测序结果显示，脂肪变性肝细胞的sEVs中富集了miR-30a-3p。miR-30a-3p直接靶向ABCA1 3'UTR抑制ABCA1表达和胆固醇外排。anagomiR-30a-3p治疗显著减轻HFHC喂养的ApoE-/-小鼠的动脉粥样硬化进展。此外，NAFLD患者血清sEVs降低了泡沫细胞中的胆固醇外排水平。sEV-miRNA-30a-3p相对含量与泡沫细胞胆固醇外排水平变化呈负相关。总之，脂肪变性肝细胞衍生的sEVs通过miR-30a-3p/ABCA1轴促进泡沫细胞形成和动脉粥样硬化。靶向和减少肝脏脂肪变性sEVs分泌或miR-30a-3p可能是减缓NAFLD驱动的AS进展的潜在治疗方法。久坐不动的生活方式和高热量食物的过度消费导致非酒精性脂肪性肝病(NAFLD)成为全球最普遍的肝病。有证据表明，NAFLD可影响包括心血管疾病(CVDs)在内的主要肝外代谢。肝脂肪变性与CVD和CVD相关事件的风险密切相关。动脉粥样硬化(AS)的发展和进展是心血管疾病的病理生理基础。然而，肝脂肪变性加速AS发展和进展的确切机制尚不清楚。细胞外囊泡(Extracellular vesicles，简称EVs)是源自供体细胞的膜状颗粒，可将其载货蛋白或miRNA运送到受体细胞，在代谢信号的器官间传递中发挥重要作用。作为细胞内通信的载体，EVs载货量可随着供体细胞受到的刺激而改变。小EVs通常指直径小于200 nm的EVs，其中包括外泌体和微泡。脂质超载后，肝细胞来源的sEVs在释放sEVs的数量和组成方面显示出巨大的变化。来自脂肪变性肝细胞的小EVs可加重肝脏炎症和NAFLD进展。然而，来自脂肪性肝细胞的sEVs是否会影响肝外代谢状况，尤其是AS，以及来自肝脂肪变性的细胞特异性信号如何调节AS进展仍然是悬而未决的问题。机理模式图（图源自Journal of Hepatology）动脉内膜中富含胆固醇的泡沫细胞是动脉粥样硬化进展的标志。动脉粥样硬化中泡沫细胞的主要细胞类型是巨噬细胞，巨噬细胞可以通过逆向胆固醇转运降低过量的细胞胆固醇水平 (RCT)。RCT的第一步是HDL通过ABCA1、ABCG1或SR-BI转运蛋白促进巨噬细胞的胆固醇外排，然后HDL-胆固醇被转运到肝脏排泄。越来越多的证据表明，巨噬细胞的RCT损伤会加剧AS的进展。该研究从脂肪变性肝细胞中分离了sEVs，并分析了这些sEVs在泡沫细胞形成和AS进展中的作用。研究结果表明，脂肪变性肝细胞来源的sEVs通过miR-30a-3p/ABCA1途径抑制巨噬细胞RCT，从而加剧泡沫细胞的形成和AS的进展，这表明抑制脂肪变性肝细胞的sEVs分泌或靶向miR-30a-3p可能能够改善NAFLD驱动的AS。此外，该研究肝脂肪变性在AS进展中的因果作用提供了概念验证的实验证据。总之，该研究揭示了肝脂肪变性通过sEVs在AS进展中的因果作用。来自脂肪变性肝细胞的sEVs可通过miR-30a-3p/ABCA1轴促进泡沫细胞形成。靶向和抑制sEVs分泌或miR-30a-3p可能是减轻NAFLD驱动的AS发展和进展的新治疗方法。文章来源“iNture”责编|文竞择校对|文竞择End往期精选围观历史性突破！不需卵子和精子就可以合成人类胚胎热文富豪用儿子血浆“回春”科学吗？Science：血液牛磺酸缺乏驱动衰老热文世界首例！35岁的她，通过机器人操刀移植的子宫，成功诞下宝宝热文为了避免心脏骤停，53岁的他成为“第一个”植入开创性除颤器的心脏病患者热文首次披露！175家生物制药公司的薪资数据：薪资中位数达20万美元点击“阅读原文”，了解更多~

研究发现高密度脂蛋白通过调控非编码RNA影响血管新生的新机制

冠心病是动脉粥样硬化导致冠状动脉狭窄和闭塞，引起心肌缺血、梗死的高死亡率心血管疾病。血管新生构建侧支循环对于心肌组织的血运重建十分重要。然而，冠心病状态下，多种危险因素持续损伤血管的功能，导致一系列促冠心病是动脉粥样硬化导致冠状动脉狭窄和闭塞，引起心肌缺血、梗死的高死亡率心血管疾病。血管新生构建侧支循环对于心肌组织的血运重建十分重要。然而，冠心病状态下，多种危险因素持续损伤血管的功能，导致一系列促进血管生长的措施没有疗效，其中一个关键因素是高密度脂蛋白(HDL)的功能障碍。正常HDL (nHDL)具有诱导血管新生的功能，但在冠心病等状态下，HDL的组分发生改变，导致诱导血管新生的功能丧失，甚至损伤血管新生，这种HDL称为失功能HDL(dHDL)。目前，对于dHDL为什么丧失诱导血管新生功能的机制尚未完全清楚。非编码RNA（Non-coding RNA）是指不编码蛋白质的RNA。其中包括微小RNA（miRNA），长链非编码RNA (lncRNA)等。这些RNA的共同特点是都能从基因组上转录而来，但是不翻译成蛋白，在RNA 水平上能行使各自的生物学功能了。其中lncRNA是一类大于200nt的非编码RNA，它的数量极其庞大，功能复杂多样，可调节血管细胞的增殖、衰老、凋亡等细胞活动，影响血管的生长和功能。我院区景松教授团队前期研究发现nHDL和dHDL诱导血管内皮细胞的lncRNA表达谱存在明显差异。然而，这些lncRNAs在nHDL和dHDL调节血管新生中的作用尚未清楚。2023年8月14日，中山大学附属第一医院区景松教授团队在Signal Transduction and Targeted Therapy 在线发表了题为“High-density lipoprotein regulates angiogenesis by long non-coding RNA HDRACA”的研究论文，首次发现nHDL通过抑制血管内皮细胞的lncRNA HDRACA表达来促进血管新生，而在冠心病状态下，dHDL对HDRACA的抑制明显减弱，导致dHDL丧失促进血管新生的功能。团队首先通过对lncRNA测序结果分析筛选，发现HDRACA可调节血管内皮细胞的增殖和管状形成，并确定了HDRACA是定位于内皮细胞浆中的长度553nt的无蛋白编码能力的lncRNA。进一步实验证实，nHDL可降低血管内皮细胞中的HDRACA表达，而dHDL对HDRACA表达的降低作用明显减弱。通过一系列分子实验发现，nHDL携带的S1P可与血管内皮细胞的S1P1相互作用诱导WWP2泛素连接酶磷酸化激活，催化HDRACA的转录因子KLF5泛素化降解，抑制HDRACA的转录。而dHDL携带的S1P含量明显减少，导致dHDL对HDRACA表达的抑制作用明显减弱。进一步实验证实nHDL抑制血管内皮细胞的HDRACA表达可促进血管新生，而dHDL对HDRACA表达的抑制明显减弱，导致它无法有效地促进血管新生。团队还发现HDRACA可以结合重要的血管新生调节蛋白RAIN，抑制RAIN和Vigilin的相互作用，进一步促进Vigilin诱导PCNA的mRNA不稳定降解，从而抑制PCNA的表达。nHDL通过抑制HDRACA表达影响RAIN-Vigilin-PCNA相互作用，促进PCNA的表达而促进血管新生。而dHDL无法有效地抑制HDRACA的表达，导致PCNA的表达减少，无法促进血管新生。该研究阐明了nHDL通过抑制lncRNA HDRACA表达促进血管新生，dHDL不能有效抑制lncRNA HDRACA表达而丧失诱导血管新生的作用和机制，为冠心病的血管新生治疗提供新的研究方向和靶点。 HDL通过调控lncRNA HDRACA影响血管新生此外，近年研究发现，HDL不但包含多种蛋白质和脂质，而且还携带非编码RNA，区景松教授团队发现，dHDL携带miRNA-24-3p明显nHDL多，nHDL可以通过HDL的经典受体SRB1抑制血管内皮细胞miRNA-24-3p的表达，从而使vinculin表达增多，激活PI3K-AKT-eNOS/ERK信号通路促进血管新生，但dHDL可以通过SRB1将携带的miRNA-24-3p导入血管内皮细胞，从而使vinculin表达下降，抑制PI3K-AKT-eNOS/ERK信号通路损伤血管新生。研究发现以题为“Angiogenic and antiangiogenic mechanisms of high density lipoprotein from healthy subjects and coronary artery diseases patients发表在期刊Redox Biology上。最近，区景松教授团队还发现HDL可以通过调控不同的miRNA影响血管新生。nHDL通过SRB1抑制另一个miR-181a-5p表达，使ATG5表达上调促进自噬，增强eNOS表达，增加内皮一氧化氮（NO）产生，诱导血管新生。 dHDL通过SRB1增强miR-181a-5p表达，抑制ATG5表达从而抑制自噬，下调eNOS表达，刺激氧自由基产生，损伤血管新生。通过过表达ATG5增加自噬可以恢复高胆固醇血症的血管新生。研究发现以文章题为：“High-density lipoprotein regulates angiogenesis by affecting autophagy via miRNA-181a-5p”于2023年6月20日在线发表在期刊Science China-Life Sciences上。综上，区景松教授团队近年来的研究系统地阐明了高密度脂蛋白通过调控非编码RNA影响血管新生的新机制, 为缺血性心脏病的血管新生治疗提供新的理论基础和治疗靶点。该研究得到国家重点研发计划项目、国家杰出青年科学基金、国家自然科学基金重大研究计划重点项目、国家自然科学基金重点项目、科技部国际重大合作项目等的联合资助。
