Abstract
Angelica sinensis (AS) can improve the haematopoietic function, but the treatment mechanism is unknown. Transfusion dependency was estimated by Kaplan-Meier survival analyses and Cox proportional-hazard model in AS treated apalstic anemia (AA) patients. After that, the AA GEO database was analysed, the up differentially expressed genes (DEGs) of AA were combined with AS targets for the intersection of targets. After the AA mouse model was established, the effect of AS was confirmed by haematopoietic function tests. The same experiment plus mitochondrial apoptotic pathway tests in vivo were performed in Angelica sinensis polysaccharide (ASP)-treated mice, the key ingredient in AS. For in vitro experiment, bone marrow nucleated cells (BMNCs) were tested. Clinical data confirmed that the level of transfusion dependency and IL17A were lower in AS-users compared to non-AS users (p < 0.001). The intersection of targets between AA and AS most concentrated on inflammation and apoptosis. Then, the same effect was found in AS treated AA mice model. In both in vivo and in vitro tests, ASP demonstrated the ability to mitigate P38/MAPK-induced Bax-associated mitochondrial apoptosis, while also reducing the levels of activated Th17 cells and alleviating abnormal cytokine levels. So, the protective effect of AS and ASP on hematopoietic function lies in their ability to prevent apoptosis.

Improvement of idiopathic pulmonary fibrosis through a combination of Astragalus radix and Angelica sinensis radix via mammalian target of rapamycin signaling pathway-induced autophagy in rat. J Thorac Dis 2024; 16:1397-1411. [PMID: 38505077 PMCID: PMC10944740 DOI: 10.21037/jtd-24-28] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2024] [Accepted: 02/18/2024] [Indexed: 03/21/2024]
Abstract
Background There is a major need for effective, well-tolerated treatments for idiopathic pulmonary fibrosis (IPF) in clinic. Astragalus radix (AR; Huangqi) and Angelica sinensis radix (AS; Danggui) have been frequently used in the treatment of IPF. This study aimed to reveal the pharmacological effects and the mechanisms of the action of an AR-AS combination in treating IPF. Methods Sprague-Dawley rats were randomly divided into six groups (n=5): control, bleomycin (BLM) model, AR, AS, AR + AS, and prednisone (PDN) groups. A transforming growth factor-β1 (TGF-β1)-induced MRC-5 cell model were also used. Pulmonary fibrosis, inflammation, oxidative stress, and autophagy were evaluated by performing hematoxylin and eosin (H&E) staining, Masson staining, immunohistochemical staining, quantitative real-time polymerase chain reaction (qRT-PCR), Western blotting, enzyme-linked immunosorbent assay (ELISA), immunofluorescence, and hydroxyproline assay following the treatment of AR, AS, and the AR-AS herb pair. Results Rats administered the AR-AS herb pair had lower α-smooth muscle actin (α-SMA), collagen I, fibronectin, and vimentin levels in lung tissues, and lower inflammatory cytokine levels in rat serum. In addition, the AR-AS herb pair induced mammalian target of rapamycin (mTOR)-mediated autophagy and reduced oxidative stress in BLM-induced rats. The effects of the AR and AS combination were confirmed in MRC-5 cells treated with TGF-β1. Specifically, the combination of AR and AS attenuated MRC-5 cell fibrosis, inflammation, and oxidative stress while inducing autophagy. Conclusions The combination of AR and AS protects against IPF by inducing autophagy via inhibiting the mTOR signaling pathway. The synergistic action of AR and AS is superior to that of either AR or AS alone.

Orientin alleviates ox-LDL-induced oxidative stress, inflammation and apoptosis in human vascular endothelial cells by regulating Sestrin 1 (SESN1)-mediated autophagy. J Mol Histol 2024; 55:109-120. [PMID: 38165567 DOI: 10.1007/s10735-023-10176-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Accepted: 11/04/2023] [Indexed: 01/04/2024]
Abstract
Endothelial cells are a crucial component of the vessel-tissue wall and exert an important role in atherosclerosis (AS). To explore the role of Orientin in AS, human vascular endothelial cells (HUVECs) were induced by oxidized low-density lipoprotein (ox-LDL) to simulate the vascular endothelial injury during AS. Cell viability was detected by CCK-8 assay. Oxidative stress and inflammation related markers were measured using kits, RT-qPCR or western blot. Besides, cell apoptosis was assessed with TUNEL staining and cell autophagy was evaluated by LC3 immunofluorescent staining. Additionally, western blot was utilized to evaluate the expression of Sestrin 1 (SESN1) and proteins in AMPK/mTOR signaling. Afterwards, SESN1 was silenced to determine the expression of autophagy-related proteins. The further application of autophagy inhibitor 3-methyladenine (3-MA) was used to clarify the regulatory mechanism of Orientin on autophagy. Results showed that the decreased viability of HUVECs caused by ox-LDL induction was elevated by Orientin. Oxidative stress and inflammation were also attenuated after Orientin addition in HUVECs under ox-LDL condition. Moreover, Orientin suppressed apoptosis and induced autophagy of HUVECs stimulated by ox-LDL, accompanied by enhanced level of phospho (p)-AMPK and declined level of p-mTOR. Interestingly, SESN1 level was elevated by Orientin, and SESN1 depletion alleviated autophagy and reduced p-AMPK expression but enhanced p-mTOR expression. The further experiments indicated that SESN1 silencing or 3-MA addition reversed the inhibitory effects of Orientin on the oxidative stress, inflammation and apoptosis of HUVECs. Collectively, Orientin could induce autophagy by activating SESN1 expression, thereby regulating AMPK/mTOR signaling in ox-LDL-induced HUVECs.

Abstract
Angiogenesis and immunosuppression are closely related pathophysiologic processes. Widely prescribed in malignant tumor and proliferative retinal lesions, VEGF signaling pathway inhibitors may cause hypertension and renal injury in some patients, presenting with proteinuria, nephrotic syndrome, renal failure and thrombotic microangiopathy. VEGF signaling pathway inhibitors block the action of both VEGF-A and VEGF-C. However, VEGF-A and VEGF-C produced by podocytes are vital to maintain the physiological function of glomerular endothelial cells and podocytes. There is still no effective treatment for kidney disease associated with VEGF signaling pathway inhibitors and some patients have progressive renal failure even after withdrawal of the drug. Recent studies reveal that blocking of VEGF-A and VEGF-C can activate CD4 +and CD8+ T cells, augment antigen-presenting function of dendritic cells, enhance cytotoxicity of macrophages and initiate complement cascade activation. VEGF and VEGFR are expressed in immune cells, which are involved in the immunosuppression and cross-talk among immune cells. This review summarizes the expression and function of VEGF-A and VEGF-C in the kidney. The current immunoregulation mechanisms of VEGF signaling pathway inhibitors are reviewed. Finally, combinate strategies are summarized to highlight the proposal for VEGF signaling pathway inhibitors.

Inflamm Res 2023; 72:429-442. [PMID: 36583755 DOI: 10.1007/s00011-022-01681-0] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Revised: 12/10/2022] [Accepted: 12/16/2022] [Indexed: 12/31/2022] Open
Abstract
OBJECTIVE Accumulating evidence has demonstrated that N6-methyladenosine (m6A) plays important roles in many major diseases, including atherosclerosis (AS). In the present study, we aimed to explore the transcriptomic m6A landscape of endothelial function-associated genes and identify potential regulators in AS progression. METHODS The GEO data (GSE142386) from MeRIP-seq in human umbilical vein endothelial cells (HUVECs) with METTL3 knocked down or not were analyzed. RNA-seq was performed to identify differences in gene expression. Gene ontology (GO) functional and Kyoto encyclopedia of genes and genomes (KEGG) pathway analyses were conducted to evaluate the potential functions of the differentially expressed genes. MeRIP-qPCR was used to measure the m6A and mRNA levels of the top 8 downregulated genes, and NPC1L1 was selected as the candidate gene. Oxidized low-density lipoprotein (ox-LDL) was used to stimulate HUVECs, and METTL3 or NPC1L1 was silenced in ox-LDL-treated cells. And Transwell, ELISA, and cell apoptosis assays were performed to assess cell functional injury. ApoE-/- mice were fed with high-fat diet for 8 weeks to establish an AS model, and adenovirus-mediated NPC1L1 shRNA or NC shRNA was injected into the mice through the tail vein. Mouse aortic tissue damage and plaque deposition were evaluated by H&E, Oil Red O, and TUNEL staining. RESULTS One hundred and ninety-four hypermethylated m6A peaks and 222 hypomethylated peaks were detected in response to knockdown of METTL3. Genes with altered m6A peaks were significantly involved in the histone modification, enzyme activity, and formation of multiple complexes and were predominantly enriched in the MAPK pathway. NPC1L1 was a most significantly downregulated transcript in response to knockdown of METTL3. Moreover, knockdown of NPC1L1 or de-m6A (METTL3 knockdown)-mediated downregulation of NPC1L1 could improve ox-LDL-induced dysfunction of HUVECs in vitro and high-fat diet-induced atherosclerotic plaque in vivo, which was associated with the inactivation of the MAPK pathway. CONCLUSION METTL3-mediated NPC1L1 mRNA hypermethylation facilitates AS progression by regulating the MAPK pathway, and NPC1L1 may be a novel target for the treatment of AS.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Atherosclerosis (AS) is a common systemic disease with increasing morbidity and mortality worldwide. Traditional Chinese medicine (TCM) with characteristics of multiple pathways and targets, presents advantages in the diagnosis and treatment of atherosclerosis. AIM OF THE STUDY With the modernization of TCM, the active ingredients and molecular mechanisms of TCM for AS treatment have been gradually revealed. Therefore, it is necessary to examine the existing studies on TCM therapies aimed at regulating AS over the past two decades. MATERIALS AND METHODS Using "atherosclerosis" and "Traditional Chinese medicine" as keywords, all relevant TCM literature published in the last 10 years was collected from electronic databases (such as Elsevier, Springer, PubMed, CNKI, and Web of Science), books and papers until March 2022, and the critical information was statistically analyzed. RESULTS In this review, we highlighted extracts of 8 single herbs, a total of 41 single active ingredients, 20 TCM formulae, and 25 patented drugs, which were described with chemical structure, source, model, efficacy and potential mechanism. CONCLUSION We summarized the cytopathological basis for the development of atherosclerosis involving vascular endothelial cells, macrophages and vascular smooth muscle cells, and categorically elaborated the medicinal TCM used for AS, all of which provide the current evidence on the better management of atherosclerosis by TCM.

Abstract
Materials and Methods CCK-8 (cell counting kit-8), Western blotting and Annexin V-FITC/PI staining were used to detect cell viability and apoptosis after hypoxia stimulation. The level of microRNA-92 a (miR-92 a) was detected by qRT-PCR.. Then, the assays of flow cytometry and the annexin V/PI staining kit were applied to value the impact of FA on hypoxia-induced cell proliferation, cell cycle distribution, and apoptosis. Furthermore, the inhibitor and mimic of miR-92a were also administrated to explore the role of miR-92a in this process. Student's t-test was used to explore the differences between two groups, while one-way analysis of variance (ANOVA) was used to explore the differences between more than two groups. Results The results showed that hypoxia stimulation significantly inhibited HUVEC viability and proliferation, such as remarkably decreasing the expression of CDK2, CDK4, and cyclin D1 in HUVECs. The results of annexin V-FITC/PI apoptosis detection showed that hypoxia culture significantly induced HUVEC apoptosis, which indicated that hypoxia stimulation significantly inhibited viability and proliferation of HUVECs but caused cell apoptosis and the expression of miR-92a. Meanwhile, FA remarkably protected HUVECs from hypoxia-induced inhibition of viability and proliferation, as well as the enhancement of apoptosis and miR-92a expression. Furthermore, suppression of miR-92a enhanced the protective effects of FA on hypoxia-induced HUVECs, while activation of miR-92a reversed those effects. Conclusion Our study reported that FA preserved HUVECs from hypoxia-induced injury via regulating miR-92a, which facilitated the understanding of the protective capacity of FA in hypoxia-caused HUVEC injury.

Abstract
To explore the METTL14-dependent m6A modification mechanism involved in the development of atherosclerosis. Oxidized low-density lipoprotein (ox-LDL) and the HUVEC cell line were used to establish an atherosclerosis cell model in vitro, and APOE−/− mice fed a high-fat diet were used as the animal model. Cell viability and apoptosis were assessed using MTT assays and flow cytometry. The status of m6A in HUVECs was examined using MeRIP-qPCR. Oil Red O staining was used to evaluate the lesions or plaques on aortas separated from the target mice. METTL14 and METTL3 were upregulated in HUVECs after ox-LDL treatment. After transfection with si-METTL14, the bcl-2 expression level and the viability of ox-LDL-incubated cells increased, whereas the apoptosis rate and the expressions of Bax and cleaved caspase-3 decreased. However, the effect of METTL14 knockdown was reversed by p65 overexpression. After METTL14 knockdown, there was a decrease in the total m6A content in HUVECs, m6A modification, and p65 expression. The plaques and lesion areas on the high-fat diet APOE−/− mouse aortas were smaller after METTL14 silencing. METTL14 reduced cell viability and promoted apoptosis of HUVECs, which were both induced by ox-LDL via m6A modification of p65. Knocking down METTL14 could inhibit the development of atherosclerosis in high-fat diet-treated APOE−/− mice.

Abstract
Chinese herbal medicines have long been used for the treatment of dysmenorrhea. The treatment experiences of traditional Chinese medicine (TCM) pharmacies passed down through generations have contributed to a wealth of prescriptions for dysmenorrhea that have achieved significant therapeutic effects in countless Taiwanese women. Therefore, surveying and analyzing these prescriptions may enable us to elucidate the core medication combinations used in TCM prescriptions for dysmenorrhea. In the present study, a field investigation was conducted on various TCM pharmacies in Taiwan. A total of 96 TCM pharmacies were sampled, and 99 prescriptions for dysmenorrhea containing 77 different medicinal materials were collected. Compositae (8%) was the most common botanical source of the medicinal materials, and the predominant TCM property and flavor of the materials were warm (45%) and sweet (73%), respectively. The blood-activating and stasis-dispelling effect (23%) and the qi-tonifying effect (23%) were the most prevalent traditional effects, and the modern pharmacological effects most commonly found in the materials were anti-inflammatory (73%), antitumor (59%), and analgesic (12%) effects. Network analysis of the 77 medicinal materials used in the prescriptions, which was performed using the Traditional Chinese Medicine Inheritance Support System, yielded seven core medicinal materials and the corresponding network diagram. The seven core medicinal materials ranked in order of relative frequency of citation (RFC) were Angelica sinensis (Oliv.)

Abstract
Alzheimer's disease (AD) is a common progressive neurodegenerative disease. In recent years, the research on the treatment of AD with Chinese medicine is increasing and the results are optimistic, which may provide some new options for the treatment of AD. Existing animal and clinical studies have found that Danggui Shaoyao San (DSS), which has been used in gynecological diseases, is effective in the treatment of AD. As the main component of DSS, macromolecular polysaccharide plays an indispensable role in the treatment of AD. In addition to anti-inflammatory, anti-neuronal injury, and immune regulation, polysaccharides extracted from Danggui Shaoyao San (p-DSS) also have good activities in hypoglycemia, and participate in the physiological regulation of ubiquitination, iron metabolism, intestinal flora, estrogen, and autophagy. Given that there is little systematic analysis of p-DSS, this paper reviews the possible mechanism of p-DSS in the treatment of AD, so as to provide reference for further research.

JOURNAL OF ETHNOPHARMACOLOGY 2021; 279:114364. [PMID: 34175446 DOI: 10.1016/j.jep.2021.114364] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/29/2021] [Revised: 06/16/2021] [Accepted: 06/22/2021] [Indexed: 06/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Qiguiyin, a hospital preparation of traditional Chinese medicinal formula, is a combination of Astragalus hamosus L., Angelica sinensis (Oliv.) Diels, Lonicera sempervirens L., Artemisia annua L., and Polygonum cuspidatum Siebold & Zucc. at a ratio of 12:3:3:2:2. It has been used to treat severe pneumonia caused by drug-resistant bacteria in clinical practice, while studies on its toxicological safety are rare in the literature. AIM OF THE STUDY In the present study, we aimed to develop a new application of Qiguiyin according to the general research routine of traditional Chinese medicine (TCM), and the toxicological effects of the Qiguiyin formula at the treatment phase and recovery phase were also evaluated. MATERIALS AND METHODS The rats were administered with the Qiguiyin formula at 10, 30, and 50 times of the corresponding dosage in humans for 13 consecutive weeks. During 13 weeks of the treatment phase and 4 weeks of the recovery phase, the general signs of toxicity and mortality were monitored daily, and the body weight and food consumption were determined every week. Moreover, the hematology, biochemistry, urine, organ weights, and histopathology were analyzed, and the reproductive system was examined at the end of the treatment phase or recovery phase, respectively. RESULTS The toxicological results showed no deaths and no changes in general behavior. Moreover, there was no clinically significant effect of the Qiguiyin formula on body weight or food consumption in rats. Although the Qiguiyin formula resulted in some changes in hematological, biochemical, and urinary indexes, these alterations were not related to the treatment because they remained within normal ranges throughout the 17 weeks. Besides, the main organs were not affected basically. All the above-mentioned results showed no gender difference. Furthermore, a clinical dosage of 50 times of the Qiguiyin formula did not affect the reproductive system of female rats, while it could lead to atrophied seminiferous tubules in two out of 10 male rats. However, such abnormality could not be found at the end of the recovery phase. CONCLUSIONS Overall, the Qiguiyin formula could be used safely. The administration at doses of less than 1000 g/day for 13 weeks showed no distinct toxicity or side effects.
