SIRT1: Harnessing multiple pathways to hinder NAFLD.

Non-alcoholic fatty liver disease (NAFLD) encompasses hepatic steatosis, non-alcoholic steatohepatitis (NASH), fibrosis, cirrhosis, and hepatocellular carcinoma. It is the primary cause of chronic liver disorders, with a high prevalence but no approved treatment. Therefore, it is indispensable to find a trustworthy therapy for NAFLD. Recently, mounting evidence illustrates that Sirtuin 1 (SIRT1) is strongly associated with NAFLD. SIRT1 activation or overexpression attenuate NAFLD, while SIRT1 deficiency aggravates NAFLD. Besides, an array of therapeutic agents, including natural compounds, synthetic compounds, traditional Chinese medicine formula, and stem cell transplantation, alleviates NALFD via SIRT1 activation or upregulation. Mechanically, SIRT1 alleviates NAFLD by reestablishing autophagy, enhancing mitochondrial function, suppressing oxidative stress, and coordinating lipid metabolism, as well as reducing hepatocyte apoptosis and inflammation. In this review, we introduced the structure and function of SIRT1 briefly, and summarized the effect of SIRT1 on NAFLD and its mechanism, along with the application of SIRT1 agonists in treating NAFLD.

Systematic pharmacology-based strategy to explore the mechanism of Semen Strychni for treatment of papillary thyroid carcinoma.

The aim of the study was to investigated the mechanism of Strychnos nux-vomica L. (Semen Strychni, SS) against papillary carcinoma thyroid (PTC) by combined of network pharmacology and experimental verification. By searching the TCMSP, SEA and SwissTarget Prediction database, the main active ingredients and related targets were obtained. Utilizing Venny 2.1.0 String database and Cytoscape 3.7.2 to screened the intersection target and constructed protein-protein interaction (PPI) network diagram. Using R 4.0.4 software carried out the enrichment analysis of GO and KEGG. HPLC was carried out using LC-20A modular HPLC system to identify the bioactive compound brucine present in SS. Molecular docking was performed using Discovery 2019 software. The inhibition rate was detected by CCK8 method. Western blot was used to detect the expression levels of brucine anti-PTC related pathway proteins. 14 active components were screened out, of which 4 main components showed tight relationship with PTC. SS may play the anti-PTC role by acting on two main pathways (TNF signaling pathway and MAPK signaling pathway) and mediating various biological functions. HPLC analysis revealed that brucine was a suitable marker for standardization of the SS. 4 active components exhibit strong binding energy with core protein. Brucine could significantly reduce the activity of BCPAP cells compared with isobrucine, stigmasterol, (+)-catechin. Brucine may reduce the protein expression levels of IL-6, VEGFA, JUN, TP53, 1L1B, PTGS2, BCL2, CASP3, CASP8, and CASP9 while increase the protein expression levels of BAD, cleaved-CASP3, cleaved-CASP8, and cleaved-CASP9 in BCPAP cells, respectively. The active components of SS against PTC mainly include isobrucine, stigmasterol, (+)-catechin, brucine. Among them, brucine exhibits the strongest anti-PTC activity in BCPAP cells, which may reduce the PTC-related protein expression levels. Therefore, SS may exhibits the anti-PTC activities through multiple targets and pathways.

Inflammatory bowel disease (IBD) encompasses a collection of idiopathic diseases characterized by chronic inflammation in the gastrointestinal (GI) tract. Patients diagnosed with IBD often experience necessitate long-term pharmacological interventions. Among the multitude of administration routes available for treating IBD, oral administration has gained significant popularity owing to its convenience and widespread utilization. In recent years, there has been extensive evaluation of the efficacy of orally administered herbal medicinal products and their extracts as a means of treating IBD. Consequently, substantial evidence has emerged, supporting their effectiveness in IBD treatment. This review aimed to provide a comprehensive summary of recent studies evaluating the effects of herbal medicinal products in the treatment of IBD. We delved into the regulatory role of these products in modulating immunity and maintaining the integrity of the intestinal epithelial barrier. Additionally, we examined their impact on antioxidant activity, anti-inflammatory properties, and the modulation of intestinal flora. By exploring these aspects, we aimed to emphasize the significant advantages associated with the use of oral herbal medicinal products in the treatment of IBD. Of particular note, this review introduced the concept of herbal plant-derived exosome-like nanoparticles (PDENs) as the active ingredient in herbal medicinal products for the treatment of IBD. The inclusion of PDENs offers distinct advantages, including enhanced tissue penetration and improved physical and chemical stability. These unique attributes not only demonstrate the potential of PDENs but also pave the way for the modernization of herbal medicinal products in IBD treatment.

Lian-Qu formula treats metabolic syndrome via reducing fat synthesis, insulin resistance and inflammation.

ETHNOPHARMACOLOGICAL RELEVANCE: Metabolic syndrome (MetS) is a pathological condition characterized by obesity, hyperglycemia, hypertension and hyperlipidemia that increases the risk of cardiovascular disease, type 2 diabetes and non-alcoholic fatty liver disease. The traditional Chinese medicine Lian-Qu formula (LQF) is modified from Xiaoxianxiong decoction, which has been used for coronary heart disease or metabolic disease in clinical for a long time. However, the pharmacological mechanism of LQF on MetS is unclear. AIM OF THE STUDY: Here, we explored the actions of LQF on MetS via network pharmacology and validated the mechanism in the MetS mice. MATERIALS AND METHODS: The chemical components of LQF were searched in the traditional Chinese medicine systems pharmacology database and the natural product activity & species source database. The related targets of MetS disease were gathered from genes cluster with literature profiles database. The protein-protein interaction network was constructed to obtain the key target genes. The Gene Ontology analysis and Kyoto Encyclopedia of Genes and Genomes pathway enrichment of the key targets were performed to predict the potential mechanisms of LQF action on MetS. And then, the high-fat diet-induced MetS mice were used to validate its therapeutic effect and molecular targets. Insulin tolerance test and oral glucose tolerance test were used to assess insulin sensitivity. Body weight and visceral fat index were measured to assess obesity. Liver metabolism was detected by H&E section, oil red O staining and untargeted lipid metabolomics experiments. Finally, the key targets of LQF action on MetS were verified by PCR and ELISA kits. RESULTS: A total of 466 components in LQF were obtained, among which 71 were active. These components correspond to 74 targets associated with MetS. The predicted targets of LQF worked on MetS were AKT1, INSR, PPARs, FASN, LDLR, TNF, CRP, IL-6, IL-1ß and so on. Furthermore, these targets were related to pathways in cellular response to lipid, inflammatory response, glucose transmembrane transport and insulin resistance. Finally, the animal experiments validated that LQF inhibited lipids accumulation by inhibiting the gene expression of FASN and increasing ADPN, and it relieved insulin resistance by increasing GLUT-4 expression. Moreover, LQF alleviated inflammation by reducing IL-6 and CRP levels. CONCLUSION: LQF exerted anti-MetS effects through improving insulin sensitivity, ameliorating hyperlipidemia and obesity, reducing liver injury, and inhibiting inflammatory response.

Modification of C20 oxidase in tanshinone biosynthesis pathway / 中国中药杂志

Tanshinones are one of the main effective components of Salvia miltiorrhiza, which play important roles in the treatment of cardiovascular diseases. Microbial heterogony production of tanshinones can provide a large number of raw materials for the production of traditional Chinese medicine(TCM) preparations containing S. miltiorrhiza, reduce the extraction cost, and relieve the pressure of clinical medication. The biosynthetic pathway of tanshinones contains multiple P450 enzymes, and the catalytic element with high efficiency is the basis of microbial production of tanshinones. In this study, the protein modification of CYP76AK1, a key P450-C20 hydroxylase in tanshinone pathway, was researched. The protein modeling methods SWISS-MODEL, Robetta, and AlphaFold2 were used, and the protein model was analyzed to obtain the reliable protein structure. The semi-rational design of mutant protein was carried out by molecular docking and homologous alignment. The key amino acid sites affecting the oxidation activity of CYP76AK1 were identified by molecular docking. The function of the obtained mutations was studied with yeast expression system, and the CYP76AK1 mutations with continuous oxidation function to 11-hydroxysugiol were obtained. Four key amino acid sites that affected the oxidation acti-vity were analyzed, and the reliability of three protein modeling methods was analyzed according to the mutation results. The effective protein modification sites of CYP76AK1 were reported for the first time in this study, which provides a catalytic element for different oxidation activities at C20 site for the study of the synthetic biology of tanshinones and lays a foundation for the analysis of the conti-nuous oxidation mechanism of P450-C20 modification.

Application of electroacupuncture in the prevention of low anterior resection syndrome after rectal cancer surgery.

BACKGROUND: Low anterior resection syndrome (LARS) is one of the common postoperative complications in patients with rectal cancer, which seriously affects their postoperative recovery and quality of life (QoL). Electroacupuncture therapy is one of the characteristic therapies of traditional Chinese medicine. There are few reports on the prevention and treatment of LARS by electroacupuncture therapy. AIM: To explore the clinical effectiveness of electroacupuncture in managing rectal cancer patients with postoperative LARS. METHODS: A total of 50 patients with LARS after rectal cancer surgery were retrospectively selected as the research subjects. According to the treatment methods, they were divided into an observation group (n = 25) and a control group (n = 25). During the four-week treatment period, the control group received standard defecation function training, while the observation group received electroacupuncture care and traditional defecation function training. The anal pressure index (which includes anal resting pressure, anal systolic pressure, and maximum tolerable volume), European Organization of Research and Treatment of Cancer (EORTC) QoL C30 (QLQ-C30) score, LARS Scale (LARSS) score, Wexner anal incontinence scale score, Xu Zhongfa five-item 10-point scale score, and the occurrence of adverse reactions were compared between the two groups before and after treatment. RESULTS: The experimental group showed considerably enhanced LARSS scores compared to those in the control group after four weeks of treatment. In the first week, second week, and fourth week, the LARSS score and Wexner anal incontinence scale score decreased, and the Xu Zhong method five-item 10-point scale score increased, with significant differences (P < 0.05). The experimental group showed substantial improvements in anal resting pressure, anal systolic pressure, and maximum tolerance volume after undergoing 4 wk of therapy in the untreated group (P < 0.05). The experimental group's QLQ-C30 score on the EORTC QoL questionnaire was higher than that of the control group during the 1st, 2nd, and 4th wk (P < 0.05). No significant variation between the groups in the frequency of adverse reactions (P > 0.05) was observed. CONCLUSION: Electroacupuncture positively impacted LARS following rectal cancer surgery, effectively improving clinical symptoms and anal pressure indicators and patients' standard of life.

[Mechanism of Shenling Baizhu Powder in alleviation of ulcerative colitis in mice based on high-throughput transcriptome sequencing].

High-throughput transcriptome sequencing was used to study the mechanism of Shenling Baizhu Powder(SLBZP) in the alleviation of the dextran sulfate sodium(DSS)-induced ulcerative colitis(UC) in mice. The mouse model of DDS-induced UC was treated with SLBZP by gavage. The changes in general state, disease activity index(DAI), and colon length were observed. The hematoxylin-eosin(HE) staining was used to observe the pathological changes in the colon tissues of mice. Enzyme-linked immunosorbent assay(ELISA) was used to determine the expression levels of tumor necrosis factor-α(TNF-α), interleukin(IL)-1ß, IL-6, IL-4, and IL-10 in the serum and tissues of mice. The differentially expressed genes in the control group, the model group, and the SLBZP group were analyzed by high-throughput transcriptome sequencing, and the Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analyses were conducted on the differentially expressed genes. The results showed that after intragastric administration of SLBZP, the symptoms of diarrhea and bloody stool were improved, and the disease active index(DAI) score was reduced. SLBZP effectively reduced the inflammatory cell infiltration and goblet cell loss in the colonic mucosal tissue, reduced the levels of TNF-α, IL-1ß, IL-6 in the serum and colon tissue, and increased the levels of IL-4 and IL-10 in the serum and colon tissue. There were 25 differential genes in SLBZP vs the model group, which were significantly enriched in immune response, immune system process, immunoglobulin production, and other biological processes. KEGG pathway analysis showed that the differential genes were enriched in signaling pathways such as neomycin, kanamycin, and gentamicin biosynthesis, cytokine-cytokine receptor interaction, primary immunodeficiency, and IgA synthesis of the intestinal immune network. This study shows that SLBZP may alleviate UC through immune regulation.

Ginsenoside Rb1 reduces oxidative/carbonyl stress damage and ameliorates inflammation in the lung of streptozotocin-induced diabetic rats.

CONTEXT: Ginsenoside Rb1 (Rb1) is a biologically active component of ginseng [Panax ginseng C.A. Meyer (Araliaceae)]. OBJECTIVE: This study determined the underlying mechanisms of Rb1 treatment that acted on diabetes-injured lungs in diabetic rats. MATERIALS AND METHODS: Streptozotocin (STZ)-induced diabetic rat model was used. Male Sprague-Dawley (SD) rats were divided into four groups (n = 10): control, Rb1 (20 mg/kg), insulin (15 U/kg to attain the euglycaemic state) and diabetic (untreated). After treatment for six weeks, oxidative stress assay; histological and ultrastructure analyses; TNF-α, TGF-ß, IL-1 and IL-6 protein expression analyses; and the detection of apoptosis were performed. RESULTS: There was decreased activity of SOD (3.53-fold), CAT (2.55-fold) and GSH (1.63-fold) and increased levels of NO (4.47-fold) and MDA (3.86-fold) in the diabetic group from control. Rb1 treatment increased SOD (2.4-fold), CAT (1.9-fold) and GSH (1.29-fold) and decreased the levels of NO (1.76-fold) and MDA (1.51-fold) as compared with diabetic rats. The expression of IL-6 (5.13-fold), IL-1α (2.35-fold), TNF-α (2.35-fold) and TGF-ß (2.39-fold) was increased in diabetic rats from control. IL-6 (2.43-fold), IL-1α (2.27-fold), TNF-α (1.68-fold) and TGF-ß (2.3-fold) were decreased in the Rb1 treatment group. Diabetes increased the apoptosis rate (2.23-fold vs. control), and Rb1 treatment decreased the apoptosis rate (1.73-fold vs. the diabetic rats). Rb1 and insulin ameliorated lung tissue injury. DISCUSSION AND CONCLUSIONS: These findings indicate that Rb1 could be useful for mitigating oxidative damage and inflammatory infiltration in the diabetic lung.

[Effect of electroacupuncture at "Tianshu" (ST25) on the regulation of nitrergic neurons in different intestinal segments in streptozotocin induced type 2 diabetic rats].

OBJECTIVE: To observe the effect of electroacupuncture (EA) at "Tianshu" (ST25) on nitrergic neurons in jejunum and distal colon in type 2 diabetic rats, so as to explore its mechanism of regulating different intestinal segments. METHODS: Twenty-four SD rats were randomly divided into control, model and EA groups (n=8 in each group). The diabetes model was established by intraperitoneal injection of streptozotocin (35 mg/kg) and high-sugar and high-fat diet for 2 weeks. EA (2 Hz/15 Hz, 2 mA) was applied to bilateral ST25 for 20 min, once a day, 6 days a week for 4 weeks. The intestinal motility was evaluated by observing the first red stool excretion time and the distal colon bead excretion time. HE staining was used to observe the histological changes of jejunum and distal colon. The positive expression and protein expression of intestinal total neuronal marker protein gene product 9.5（PGP9.5） and neuronal nitric oxide synthase (nNOS) in jejunum and distal colon were detected by immunofluorescence staining and Western blot, respectively. RESULTS: After modeling, the blood glucose was significantly increased (P<0.01), the first red stool excretion time and the distal colon bead excretion time were shortened (P<0.01), the expression levels of PGP9.5 and nNOS in jejunum and distal colon were decreased (P<0.01) in the model group relevant to the control group. After treatment, compared with the model group, the blood glucose was decreased (P<0.01), the first red stool excretion time and the distal colon bead excretion time were prolonged (P<0.01, P<0.05), and the expression levels of PGP9.5 and nNOS in jejunum and distal colon were increased (P<0.05, P<0.01) in the EA group. HE staining showed disordered structure in intestinal mucosa of the jejunum and distal colon, and reduction of the number of goblet cells in the model group, which was relatively milder in the EA group. CONCLUSION: EA can effectively improve the intestinal mucosal damage and restore intestinal motor function in type 2 diabetic rats, which may be related to its function in regulating the number of nitrergic neurons in the intestinal nervous system.

A pair of novel phenylethanol glycosides from Cistanche tubulosa (Schenk) Wight.

A pair of differential epimers with opposite C-7 configurations, crenatosides A and B (1 and 2), and 10 known phenylethanoid glycosides (PhGs) (3-12) were obtained from the succulent stem of Cistanche tubulosa. The structures were elucidated based on extensive spectral data (UV, IR, 1D and 2D NMR, HR-ESIMS), which are first reported natural products with unique glycoside structures. After acid hydrolysis, the configuration of the sugar was determined by comparing it with the normative sugar by HPLC. The absolute configurations of both compounds were determined by ECD spectrum analysis. All the obtained compounds were examined for their inhibitory effect on lipopolysaccharide (LPS)-induced nitric oxide (NO) production in mouse microglial cells (BV-2 cells), and compounds 1 and 2 showed potent inhibition on NO production with IC50 values of 5.62 µM and 6.30 µM, respectively.

Integrated Strategy of UHPLC-Q-TOF-MS and Molecular Networking for Identification of Diterpenoids from Euphorbia fischeriana Steud. and Prediction of the Anti-Breast-Cancer Mechanism by the Network Pharmacological Method.

Breast cancer is one of the most common malignancies in women worldwide. Traditional Chinese medicine has been used as adjunctive or complementary therapy for breast cancer. Diterpenoids from Euphorbia fischeriana Steud. have been demonstrated to possess anti-breast-cancer activity. This research was aimed to systematically explore the diterpenoids from E. fischeriana and study the multiple mechanisms on breast cancer. The structures of diterpenoids were identified by the integrated strategy of UHPLC-Q-TOF-MS and molecular networking. A total of 177 diterpenoids belonging to 13 types were collected. In silico ADME analysis was performed on these compounds. It indicated that 130 of 177 diterpenoids completely adjusted to Lipinski's rule. The targets of compounds were obtained from PharmMapper. The targets of breast cancer were collected from GeneCards. Then, 197 compounds-related targets and 544 breast cancer-related targets were identified. After the intersection process, 58 overlapping targets between compounds-related targets and breast cancer-related targets were acquired. The STRING database was applied to predict the protein-protein interactions. The GO and KEGG pathway enrichment analysis were performed by using the KOBAS database. It indicated that these predicted pathways were closely related to breast cancer. The treatment effect of E. fischeriana on breast cancer might be performed through signaling pathways, such as IL-17 signaling pathway, MAPK signaling pathway, and PI3K-Akt signaling pathway. The predicted top genes such as EGFR, ESR, MAPK, SRC, CASP3, CDK2, and KDR were involved in cell proliferation, gene transcription, apoptosis, signal transduction, DNA damage and repair, tumor differentiation, metastasis, and cell cycle, which indicated that E. fischeriana might treat breast cancer comprehensively. A compounds-KEGG pathways-related targets network was built by using cytoHubba to analyze the hub compounds and targets. It concluded that E. fischeriana treated breast cancer not only by the main components but also by the microconstituents, which reflected the overall regulatory role of multicomponents treating breast cancer. To estimate the binding affinities, binding sites, and binding postures, molecular docking simulations between 177 diterpenoids and top 19 targets were carried out. The results are basically in line with expectations. In conclusion, these results can serve as references for researchers studying potential targets of diterpenoids from E. fischeriana on breast cancer in the future.
