Protective effects and regulatory mechanisms of Shen-shuai-yi recipe on renal fibrosis in unilateral ureteral obstruction-induced mice.
Renal fibrosis (RF) is a common pathological feature of chronic kidney disease (CKD), which remains a major public health problem. As now, there is still lack of chemical or biological drugs to reverse RF. Shen-shuai-yi Recipe (SSYR) is a classical Chinese herbal formula for the treatment of CKD. However, the effects and mechanisms of SSYR in treating RF are still not clear. In this study, the active constituents SSYR for treating RF were explored by UHPLC-Q-Orbitrap HRMS. Bioinformatics analyses were employed to analyze the key pharmacological targets and the core active constituents of SSYR in the treatment of RF. In experimental validation, vehicle or SSYR at doses of 2.12 g/kg/d and 4.25 g/kg/d were given by orally to unilateral ureteric obstruction (UUO) mice. 13 days after treatment, we detected the severity of renal fibrosis, extracellular collagen deposition and pre-fibrotic signaling pathways. Bioinformatics analysis suggested that signal transducer and activator of transcription 3 (STAT3) was the core target and lenticin, luteolin-7-O-rutinoside, hesperidin, kaempferol-3-O-rutinoside, and 3,5,6,7,8,3′,4′-heptamethoxyflavone were the key constituents in SSYR for treating RF. SSYR significantly reduced the expressions of fibronectin (FN), α-smooth muscle actin (α-SMA), collagen-I and alleviated renal interstitial collagen deposition in UUO kidneys. In mechanism, SSYR potently blocked the phosphorylation of STAT3 and Smad3 and suppressed the expression of connective tissue growth factor (CTGF). Collectively, SSYR can ameliorate RF inhibiting the phosphorylation of STAT3 and its downstream and reducing the collagen deposition, suggesting that SSYR can be developed as a novel medicine for treating RF.
The roles of serine hydrolases and serum albumin in alisol B 23-acetate hydrolysis in humans.
lisol B 23-acetate (AB23A), a major bioactive constituent in the Chinese herb Zexie (), has been found with multiple pharmacological activities. AB23A can be readily hydrolyzed to alisol B in mammals, but the hydrolytic pathways of AB23A in humans and the key enzymes responsible for AB23A hydrolysis are still unrevealed. This study aims to reveal the metabolic organs and the crucial enzymes responsible for AB23A hydrolysis in human biological systems, as well as to decipher the impact of AB23A hydrolysis on its biological effects. The hydrolytic pathways of AB23A in human plasma and tissue preparations were carefully investigated by using Q-Exactive quadrupole-Orbitrap mass spectrometer and LC-UV, while the key enzymes responsible for AB23A hydrolysis were studied via performing a set of assays including reaction phenotyping assays, chemical inhibition assays, and enzyme kinetics analyses. Finally, the agonist effects of both AB23A and its hydrolytic metabolite(s) on FXR were tested at the cellular level. AB23A could be readily hydrolyzed to form alisol B in human plasma, intestinal and hepatic preparations, while human butyrylcholinesterase (hBchE) and human carboxylesterases played key roles in AB23A hydrolysis in human plasma and tissue preparations, respectively. It was also found that human serum albumin (hSA) could catalyze AB23A hydrolysis, while multiple lysine residues of hSA were covalently modified by AB23A, suggesting that hSA catalyzed AB23A hydrolysis its pseudo-esterase activity. Biological tests revealed that both AB23A and alisol B exhibited similar FXR agonist effects, indicating AB23A hydrolysis did not affect its FXR agonist effect. This study deciphers the hydrolytic pathways of AB23A in human biological systems, which is very helpful for deep understanding of the metabolic rates of AB23A in humans, and useful for developing novel prodrugs of alisol B with desirable pharmacokinetic behaviors.
Elucidating a fresh perspective on the interplay between exosomes and rheumatoid arthritis.
Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by chronic synovitis and the destruction of bones and joints. Exosomes are nanoscale lipid membrane vesicles originating from multivesicular bodies and are used as a vital means of intercellular communication. Both exosomes and the microbial community are essential in RA pathogenesis. Multiple types of exosomes from different origins have been demonstrated to have effects on various immune cells through distinct mechanisms in RA, which depend on the specific cargo carried by the exosomes. Tens of thousands of microorganisms exist in the human intestinal system. Microorganisms exert various physiological and pathological effects on the host directly or through their metabolites. Gut microbe-derived exosomes are being studied in the field of liver disease; however, information on their role in the context of RA is still limited. Gut microbe-derived exosomes may enhance autoimmunity by altering intestinal permeability and transporting cargo to the extraintestinal system. Therefore, we performed a comprehensive literature review on the latest progress on exosomes in RA and provided an outlook on the potential role of microbe-derived exosomes as emerging players in clinical and translational research on RA. This review aimed to provide a theoretical basis for developing new clinical targets for RA therapy.
LncRNA NEAT1 Promotes High Glucose-Induced Mesangial Cell Hypertrophy by Targeting miR-222-3p/CDKN1B Axis.
Glomerular hypertrophy is an early morphological alteration in diabetic nephropathy. Cyclin-Dependent Kinases have been shown to be required for high glucose (HG)-induced hypertrophy; however, the upstream regulators of CDKN1B in glomerular hypertrophy remain unclear. Herein we describe a novel pathway in which Long noncoding RNA (lncRNA) NEAT1 regulates the progression of mesangial cell hypertrophy via a competing endogenous RNA (ceRNA) mechanism. Real-time PCR was performed to detect the relative NEAT1 and miR-222-3p expressions and further confirmed the relationship between NEAT1 and miR-222-3p. Cell cycle was evaluated by flow cytometry. The related mechanisms were explored by Western blot, RNA immunoprecipitation and chromatin immunoprecipitation assay. We show that NEAT1 forms double stranded RNA (dsRNA) with miR-222-3p, thus limiting miR-222-3p’s binding with CDKN1B. This release of CDKN1B mRNA leads to elevated CDKN1B protein expression, resulting in hypertrophy. In addition, we demonstrated that STAT3 which is activated by HG induces the transcription of NEAT1 by binding to its promoter. Our findings underscore an unexpected role of lncRNAs on gene regulation and introduce a new mode of proliferation regulation in mesangial cells.
Mechanism research of Bu-Shen-Huo-Xue formula against renal fibrosis in rats with 5/6 nephrectomy via E-cadherin, α-SMA, and TGF- β 1, Clinical Nephrology
OBJECTIVE:Renal fibrosis generally results in renal failure during the end stage of chronic renal diseases. There are many cell factors including E-cadherin, α-SMA, and TGF-β1 influencing deposition of extracellular matrix and leading to renal fibrosis. As the most important and widely-used therapy for various diseases in China for thousands of years, traditional Chinese medicine (TCM) provides a novel treatment for renal fibrosis. For clinical application, we explore the effect of Bu-Shen-Huo-Xue formula (BSHX), a traditional Chinese herbal formula, on E-cadherin and α-SMA in rats with 5/6 nephrectomy.
MATERIALS AND METHODS:Sprague-Dawley rats were subjected to 5/6 nephrectomy to induce chronic renal failure (CRF); they were divided into three groups including a CRF control group, a BSHX group, and a Cozaar group, and compared with a normal control group. After 8 weeks of therapy with the respective drug, E-cadherin, α-SMA, and TGF were detected by immunohistochemistry assays in renal tissues.
RESULTS:As the immunohistochemistry assays indicated, BSHX could significantly enhance the expression of E-cadherin and depress the levels of α-SMA and TGF-β1 expression in rats’ renal tissues with 5/6 nephrectomy.
CONCLUSION:BSHX can effectively relieve the renal fibrosis in rats with 5/6 nephrectomy via the change of cell factor levels including enhancement of the expression of E-cadherin and depression of the levels of α-SMA and TGF-β1 expression.

Abstract
Aims One of the primary pathological features in the early stages of diabetic nephropathy is mesangial cell (MC) hypertrophy in the glomerulus. Considering the role of E3 ubiquitin ligases in regulating MC hypertrophy, the aim of this study was to identify the functional ubiquitin protein ligase E3 component N-recognin 5 (UBR5) during MC hypertrophy under high glucose conditions.
Methods Human MCs (HMCs) transduced with UBR5 silencing or overexpression vector were treated with high glucose, AKT inhibitor, or glycolysis inhibitor. Cell proliferation, cell cycle, hypertrophy and glycolysis were evaluated in the HMCs after indicated treatment. m6A methylated RNA immunoprecipitation, luciferase reporter assay, and RNA immunoprecipitation were performed to determine the regulation of UBR5 by Wilms tumor 1-associating protein (WTAP)/insulin-like growth factor 2 mRNA-binding protein 1 (IGF2BP1) induced m6A modification. Western blot was performed to determine the protein expression levels.
Results UBR5 expression was upregulated in db/db mice and in high glucose-induced HMCs. UBR5 silencing inhibited high glucose-induced HMC cell cycle arrest, cell hypertrophy, and glycolysis. UBR5 facilitated HMC hypertrophy and glycolysis by promoting the phosphorylation levels of AKT. Additionally, the promoting effect of glycolysis on cell hypertrophy were also elucidated. Further investigation into upstream regulators revealed that WTAP promoted m6A modification of UBR5 through the m6A reader IGF2BP1.
Conclusions Our study unveils a novel mechanism involved in high glucose-induced cell hypertrophy, offering new insights into the understanding and treatment of early pathological mechanisms in diabetic nephropathy.

Acute kidney injury (AKI) represents signi cant medical challenges due to its elevated rates of morbidity and mortality, with limited therapeutic options currently available. Hence, the exploration of novel medicinal treatments for AKI management remains vital. Substances of medicine food homology (SMFH), referring to substances having characteristics of both food and medicine, have been applied in China for thousands years.They could be used for daily diets and body conditioning. Traditional Chinese medicine (TCM), with its naturally derived components and demonstrated effectiveness, presents distinctive bene ts in AKI treatment. Numerous studies have shown that SMFH and TCM phytochemicals could function satisfactorily with nephroprotective effects and have a signi cant effect on alleviating AKI as well as its complications. In this review, the pathogenesis of AKI was illustrated. We concentrated on SMFH and TCM phytochemicals against AKI and tried to summarize the underlying mechanisms in various kinds of AKI, highlighting the crucial phytochemical components in AKI prevention and therapy. Besides, strategies for SMFH and TCM phytochemicals globalization are analysed. This review comprehensively reveals that SMFH and TCM phytochemicals exhibit promising potential for AKI intervention by targeting various signal pathways and targets, which would contribute to AKI’s cognition, preventive treatments, as well as global promotion.

摘要 京尼平苷酸(geniposidic acid,GA)是一种天然环烯醚萜类化合物,广泛分布在茜草科、杜仲科、车前科等药用植物的根、茎、叶、花、树皮、果实和种子中。现代药理学研究表明,GA 具有脏器保护、抗炎、抗氧化、抗骨质疏松、抗神经退行性疾病、缓解心血管疾病等多种药理活性。GA 可通过上调抗炎、抗氧化关键因子提升细胞/机体的防御能力,同时能下调AhR、TLR4/MyD88 等促炎信号通路的关键节点蛋白进而发挥脏器保护等药理作用。药代动力学研究显示GA 口服后可在多个脏器分布(肾、肝、心、脾、肺等);且在疾病状态下该化合物的药代动力学行为会发生显著改变,主要表现为口服后的系统暴露显著增加。该文全面综述了GA 已报道的多种药理活性及其药理机制,同时系统总结了GA 的药代动力学行为和参数,以期为GA 相关中成药的临床精准应用和基于GA 的创新药物研发等提供理论依据和科学参考。

abstract
Objective: To characterize the oxidative metabolic pathway(s) of pectolinarigenin (PEC) and reveal the effect of PEC oxidative metabolism on its biological activities including peroxisome proliferator-activated receptors (PPAR) and nuclear factor erythroid 2-related factor 2 (Nrf2) agonist effects, as well as the anti-oxidative and hepatoprotective activities.
Methods: The oxidative metabolites of PEC were identified by liquid chromatography-time of flight-mass spectrometry (LC-TOF-MS/MS). The key enzymes involved in oxidative metabolism of PEC were assigned by P450 reaction phenotyping assays and enzymatic kinetics assays. Luciferase reporter assays and west-ern blotting analysis were used to evaluate the Nrf2 and PPAR agonist effects of PEC and its oxidative metabolites. The intracellular levels of total reactive oxygen species (ROS), mitochondrial membrane potential (MMP), lactate dehydrogenase (LDH) and glutathione (GSH) in acetaminophen (APAP)-challenged hepatocytes were also tested.
Results: PEC could be readily metabolized to form two O-demethylated metabolites including hispidulin (HIS, 4′-O-demethylated PEC) and 6-O-demethylated PEC in human liver microsomes (HLM) in the pres-ence of nicotinamide adenine dinucleotide phosphate (NADPH), while HIS was identified as the major oxidative metabolite of PEC. At least nine human cytochrome P450 enzymes (CYP) enzymes could cat-alyze PEC-4′-O-demethylation, while CYP1A2 and CYP2D6 showed the highest binding affinities and rapid metabolic clearance rates in the oxidative metabolism of PEC. Biological assays showed that PEC 4′-O-demethylation slightly decreased the PPAR agonist effects of PEC, while HIS showed more potent Nrf2 agonist effect. Compared with PEC, HIS showed more efficacious hepatoprotective effect against APAP-induced hepatocyte injury, evidenced by more potent ability to reduce intracellular ROS and LDH levels, as well as more effective ability to elevate the intracellular levels of both MPP and GSH in APAP-challenged hepatocytes.
Conclusion: CYPs catalyze PEC-4′-O-demethylation to generate a more active Nrf2 agonist (HIS), which shows more efficacious hepatoprotective effects against APAP-induced hepatocyte injury.
