The ameliorative effect on chemotherapy-induced injury and tumor immunosuppressive microenvironment of the polysaccharide from the rhizome of Menispermum dauricum DC.

Abstract
Combined medication has attracted increasing attention as an important treatment option for tumors due to the serious adverse effects of chemotherapy. In this study, as a new therapy strategy, a combination treatment of MDP (a polysaccharide from the rhizome of Menispermum dauricum DC.) with cyclophosphamide (CTX) was investigated. The results showed that combination treatment with MDP and CTX exerted a significantly synergistic anti-tumor effect in Lewis tumor-bearing mice, improved CTX-induced emaciation and hair loss, as well as increased the number of leukocytes, erythrocytes, hemoglobin, and platelets in the peripheral blood. In addition, compared with CTX alone, the thymus index and spleen index of the MDP + CTX group were increased, the number of CD3 + T cells, CD8 + T cells, white blood cells and B cells in spleen also increased significantly. MDP could also ameliorate the increase in liver and kidney index caused by CTX. In the Lewis lung cancer model, MDP showed a certain degree of anti-tumor effects, which may be related to its promotion of tumor-associated macrophages (TAMs) to M1 phenotype polarisation, enhancement of the number of T cells in tumor tissues and promotion of Th cells in tumor tissues to Th1 phenotype polarisation, thus alleviating the immunosuppressive microenvironment in tumor tissues. This study laid the foundation for the development of MDP as a polysaccharide drug for the treatment or adjuvant therapy of tumors and has important significance for the further clinical application of polysaccharides.

Abstract
The objective of this study was to examine the impacts of the combing of Agrocybe aegerita polysaccharides (AAPS) with Bifidobacterium lactis Bb-12 (Bb-12) on antioxidant activity, anti-aging properties, and modulation of gut microbiota. The results demonstrated that the AAPS and Bb-12 complex significantly increased the average lifespan of male and female Drosophila melanogaster under natural aging conditions (p < 0.05), with an improvement of 8.42% and 9.79%, respectively. Additionally, the complex enhanced their climbing ability and increased antioxidant enzyme activity, protecting them from oxidative damage induced by H2O2. In D-galactose induced aging mice, the addition of AAPS and Bb-12 resulted in significantly increase in antioxidant enzyme activity, regulation of aging-related biomarker levels, changed gut microbiota diversity, restoration of microbial structure, and increased abundance of beneficial bacteria, particularly lactobacilli, in the intestines. These findings suggested that the complex of AAPS and Bb-12 had the potential to serve as a dietary supplement against organism aging and oxidative stress.

Polysaccharide from Agrocybe cylindracea prevents diet-induced obesity through inhibiting inflammation mediated by gut microbiota and associated metabolites. Int J Biol Macromol 2022; 209:1430-1438. [PMID: 35460750 DOI: 10.1016/j.ijbiomac.2022.04.107] [Citation(s) in RCA: 28] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2022] [Revised: 03/27/2022] [Accepted: 04/15/2022] [Indexed: 12/28/2022]
Abstract
Polysaccharide from Agrocybe cylindracea (ACP) has been demonstrated with various health benefits, but its anti-obesity effect and underlying mechanisms remain poorly understood. This study aimed to investigate the beneficial effects of ACP in high-fat diet (HFD)-induced obese mice by targeting gut microbiota and metabolites. 9-week ACP supplementation in HFD-fed mice reduced body weight, adipose accumulation, impaired insulin resistance, lipid levels, and liver injuries, which were negatively correlated to the pro-inflammatory factors, particularly tumor necrosis factor-alpha (TNF-α) and interleukin- 6 (IL-6). Moreover, ACP not only restored HFD-induced gut disorder, as indicated by the depletion of Desulfovibrio and Oscillibacter and the enrichment of the Bacteroides, Parabacteroides, Butyricimonas, and Dubosiella, but also positively regulated gut metabolites such as solavetivone and N-acetylneuraminic acid. Spearman's correlation analysis revealed that the ACP-altered microbes and metabolites were highly correlated with inflammation-related indexes. Notably, ACP greatly lowered the obesity-related TNF-α- and IL-6-levels partially by reducing Desulfovibrio and increasing Parabacteroides abundances, together with the associated decrease of solavetivone level. These findings suggest that ACP may be used as a prebiotic agent to prevent diet-induced obesity, and target-specific microbiota and metabolites may have unique therapeutic promise for inflammation-related diseases.

Abstract
Traditional chemotherapy is being considered due to hindrances caused by systemic toxicity. Currently, the administration of multiple chemotherapeutic drugs with different biochemical/molecular targets, known as combination chemotherapy, has attained numerous benefits like efficacy enhancement and amelioration of adverse effects that has been broadly applied to various cancer types. Additionally, seeking natural-based alternatives with less toxicity has become more important. Experimental evidence suggests that herbal extracts such as Solanum nigrum and Claviceps purpurea and isolated herbal compounds (e.g., curcumin, resveratrol, and matairesinol) combined with antitumoral drugs have the potential to attenuate resistance against cancer therapy and to exert chemoprotective actions. Plant products are not free of risks: Herb adverse effects, including herb-drug interactions, should be carefully considered.

Abstract
Sepsis is one of the leading causes of death with unsatisfactory current treatments. The present study assessed the liver protective effect of glucocorticoids on different levels of inflammation in septic shock rats. A rat septic shock model was established by lipopolysaccharide (LPS) injection. Rats were divided into control (Control), high-inflammation treated with hydrocortisone (HT), high-inflammation non-treatment (HNT), low-inflammation treated with hydrocortisone (LT) and low-inflammation non-treatment (LNT) groups according to the levels of serum C-reactive protein (CRP), interleukin (IL)-6 and interferon (IFN)-γ. The mean arterial pressure and heart rate changes were continuously monitored and aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels were measured by an automatic biochemical analyzer. Hematoxylin and eosin (H&E) staining was performed to observe the pathological changes of liver tissue. Western blot analysis was used to detect the expression of p38 mitogen-activated protein kinase (MAPK) and NF-κB protein. The results demonstrated that following 7 days of treatment, there were no obvious differences in the serum CRP, IL-6 and IFN-γ levels between the HT group and the control group, whilst the HNT group, LT group and LNT group were significantly different compared with the HT and control groups. H&E staining demonstrated that the liver cells in the HT group were homogeneous following 7 days of treatment. Western blot analysis determined that the phosphorylation levels of p38MAPK and NF-κB in HT group were reduced significantly compared with the LT group, while there was no obvious difference with the control group after 7 days treatment. The present results indicated that glucocorticoids have better therapeutic effect on septic shock rats with high-inflammation compared with low-inflammation rats. The present study provides a novel approach for glucocorticoid treatment of septic shock.

Abstract
Lectin is a protein with multiple functions. In this study, the full-length cDNA of the Agrocybe aegerita lectin (AAL) gene was cloned, recombinant AAL (AAL-His) was expressed, and the activities of AAL-His were analyzed. Northern blot analysis showed that the major AAL transcript is approximately 900 bp. Sequence analysis showed that the coding region of AAL is 489 bp with a transcription start site located 39 nucleotides upstream of the translation initiation codon. In an agglutination test, AAL-His agglutinated rabbit erythrocytes at 12.5 μg/ml. AAL-His also showed antiviral activity in protecting shrimp from white spot syndrome virus (WSSV) infection. This anti-WSSV effect might be due to the binding of AAL-His on WSSV virions via the direct interactions with four WSSV structural proteins, VP39B, VP41B, VP53A and VP216. AAL demonstrates the potential for development as an anti-WSSV agent for shrimp culture. It also implies that these four AAL interaction WSSV proteins may play important roles in virus infection.

Abstract
Total alkaloids is an active ingredient of the natural plant Rubus alceifolius Poir, commonly used for the treatment of various cancers. Antitumor effects may be mediated through anti-angiogenic mechanisms. As such, the goal of the present study was to investigate and evaluate the effect of total alkaloids in Rubus alceifolius Poir (TARAP) on tumor angiogenesis and investigate the underlying molecular mechanisms of TARAP action in vivo and in vitro. A chick embryo chorioallantoic membrane (CAM) assay was used to assess angiogenesis in vivo. An MTT assay was performed to determine the viability of human umbilical vein endothelial cells (HUVECs) with and without treatment. Cell cycle progression of HUVECs was examined by FACS analysis with propidium iodide staining. HUVEC migration was determined using a scratch wound method. Tube formation of HUVECs was assessed with an ECMatrix gel system, and mRNA and protein expression of VEGF-A in both HUVECs and HepG2 human hepatocellular carcinoma cells were examined by RT-PCR and ELISA, respectively. Our results showed that TARAP inhibited angiogenesis in the CAM model in vivo and inhibited HUVEC proliferation via blocking cell cycle G1 to S progression in a dose- and time-dependent manners in vitro. Moreover, TARAP inhibited HUVEC migration and tube formation and downregulated mRNA and protein expression of VEGF-A in both HepG2 cells and HUVECs. Our findings suggest that the anti-angiogenic activity of TARAP may partly contribute to its antitumor properties and may be valuable for the treatment of diseases involving pathologic angiogenesis such as cancer.
