Abstract
BACKGROUND The most serious challenges in medicinal 'Sanghuang' mushroom production are the fungal diseases caused by various molds. Application of biological agents has been regarded as a potential crop disease management strategy. Here, the soil microbiome associated with 'Sanghuang' mushroom affected by fungal diseases grown under field cultivation (FC) and hanging cultivation (HC) was characterized using culture-dependent and culture-independent methods. RESULTS A total of 12,525 operational taxonomic units (OTUs) and 168 pure cultures were obtained using high-throughput sequencing and a culture-dependent method, respectively. From high-throughput sequencing, we found that HC samples had more OTUs, higher α-diversity, and greater microbial community complexity than FC samples. Analysis of β-diversity divided the soil microbes into two groups according to cultivation mode. Basidiomycota (48.6%) and Ascomycota (46.5%) were the two dominant fungal phyla in FC samples, with the representative genera Trichoderma (56.3%), Coprinellus (29.4%) and Discosia (4.8%), while only the phylum Ascomycota (84.5%) was predominant in HC samples, with the representative genera Discosia (34.0%), Trichoderma (30.2%), Penicillium (14.9%), and Aspergillus (7.8%). Notably, Trichoderma was predominant in both the culture-independent and culture-dependent analyses, with Trichoderma sp. FZ0005 showing high host pathogenicity. Among the 87 culturable bacteria, 15 exhibited varying extents of antifungal activity against Trichoderma sp. FZ0005, with three strains of Bacillus spp. (HX0037, HX0016, and HX0039) showing outstanding antifungal capacity. CONCLUSIONS Overall, our results suggest that Trichoderma is the major causal agent of 'Sanghuang' fungal diseases and that Bacillus strains may be used as biocontrol agents in 'Sanghuang' cultivation.

[PMID: 37359953 PMCID: PMC10288903 DOI: 10.1080/12298093.2023.2220164] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Revised: 05/14/2023] [Accepted: 05/28/2023] [Indexed: 06/28/2023]
Abstract
To further explore the molecular mechanism of triterpenoid biosynthesis and acquire high-value strain of Sanghuangporus baumii, the Agrobacterium tumefaciens-mediated transformation (ATMT) system was studied. The key triterpenoid biosynthesis-associated gene isopentenyl diphosphate isomerase (IDI) was transformed into S. baumii by ATMT system. Then, the qRT-PCR technique was used to analyze gene transcript level, and the widely targeted metabolomics was used to investigate individual triterpenoid content. Total triterpenoid content and anti-oxidant activity were determined by spectrophotometer. In this study, we for the first time established an efficient ATMT system and transferred the IDI gene into S. baumii. Relative to the wild-type (WT) strain, the IDI-transformant (IT) strain showed significantly higher transcript levels of IDI and total triterpenoid content. We then investigated individual triterpenoids in S. baumii, which led to the identification of 10 distinct triterpenoids. The contents of individual triterpenoids produced by the IT2 strain were 1.76-10.03 times higher than those produced by the WT strain. The triterpenoid production showed a significant positive correlation with the IDI gene expression. Besides, IT2 strain showed better anti-oxidant activity. The findings provide valuable information about the biosynthetic pathway of triterpenoids and provide a strategy for cultivating high-value S. baumii strains.

Wang Y, Liu Z, Wei J, Di L, Wang S, Wu T, Li N. Norlignans and phenolics from genus Curculigo protect corticosterone-injured neuroblastoma cells SH-SY5Y by inhibiting endoplasmic reticulum stress-mitochondria pathway. JOURNAL OF ETHNOPHARMACOLOGY 2022; 296:115430. [PMID: 35659626 DOI: 10.1016/j.jep.2022.115430] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/15/2022] [Revised: 05/22/2022] [Accepted: 05/31/2022] [Indexed: 06/15/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The plants of genus Curculigo are divided into the Section Curculigo and the Section Capitulata, which are mainly distributed in southeastern and southwestern China. Various ancient chinese books record that these plants were used as an important herb for tonifying kidney yang. Traditional Chinese medicine often draws on this property to treat depression syndrome. Thus genus Curculigo has potential for the treatment of neurodegenerative diseases (ND). The study showed that phenolics were the main characteristic components of plants in the Section Curculigo, represented by orcinol glucoside and curculigoside; the norlignans, with Ph-C5-Ph as the basic backbone, were the main characteristic components of the Section Capitulata. However, there is a lack of sufficient scientific evidence as to whether these two types of ingredients have neuroprotective effects. AIM OF THE STUDY To determine the neuroprotective effects of phenolics and norlignans in genus Curculigo on human neuroblastoma cells SH-SY5Y. To discuss their structure-activity relationship and screen for compounds with high activity and neuroprotective effects. To reveal that the amelioration of endoplasmic reticulum (ER) stress by two classes of compounds is mediated by the PERK/eIF2α/ATF4 pathway. MATERIALS AND METHODS The cytotoxicity of 17 compounds was assayed by MTT. SH-SY5Y cells were damaged by corticosterone (Cort) (200 μM) for 24 h and then co-administered with 17 compounds (0.1-100 μM) and Cort (200 μM) for 24 h. Cell survival was determined by MTT assay. Apoptosis rate, mitochondrial membrane potential (MMP) and intracellular reactive oxygen species (ROS) levels were detected using flow cytometry. Intracellular Ca2+ levels were detected using a fluorescent probe. Cellular mitochondrial and ER damage was observed using transmission electron microscopy (TEM). ER stress and apoptotic pathway-related proteins (BiP, CHOP, cleaved caspase-3, cleaved caspase-9, Bax/Bcl-2), and the expression level of PERK/eIF2α/ATF4 pathway was measured via western blot (WB). RESULTS The experimental data showed that Cort treatment of SH-SY5Y cells resulted in decreased cell survival and increased apoptosis, mitochondrial depolarization, ROS, and intracellular Ca2+ levels. The co-action of 17 compounds and Cort for a period of time significantly increased cell survival. Compounds 3, 7, 12, 13 also reduced apoptosis rate, mitochondrial depolarization, ROS and intracellular Ca2+ levels in the subsequent experiments. In addition, TEM observed that Cort caused mitochondrial and ER damage, and the damage was improved after treatment. WB analysis obtained that Cort increased the expression of apoptotic and ER stress-related proteins and activated pathway expression. However, in the presence of compounds 3, 7, 12, 13, the expression of BiP, CHOP, cleaved caspase-3, cleaved caspase-9, and Bax/Bcl-2 was significantly reduced, and the phosphorylation of PERK and eIF2α and the expression of ATF4 were inhibited. CONCLUSION This study found that one phenolic (3) and three norlignans (7, 12, 13) from genus Curculigo have significant neuroprotective effects. The results of the structure-activity relationship indicated that the glucosyl polymeric norlignans and the phenolics with benzoic acid as the parent nucleus were more active. The neuroprotective effect of three norlignans is the latest discovery. This finding has important research value in the field of prevention and treatment of neurodegenerative diseases.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 100:154075. [PMID: 35413646 DOI: 10.1016/j.phymed.2022.154075] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Revised: 02/05/2022] [Accepted: 03/25/2022] [Indexed: 06/14/2023]
Abstract
BACKGROUND Osmundacetone (OSC) is a bioactive phenolic compound isolated from Phellinus igniarius and that was shown to exert cytotoxic effects on cancer cells in our previous work. The antiproliferative impact of OSC on non-small cell lung cancer (NSCLC) and the underlying mechanisms, however, have not been studied. PURPOSE This study aimed to explore the antiproliferative effect of OSC on NSCLC cells and the mechanisms involved. METHODS Cell viability, colony formation and cell cycle distribution were measured following exposure to OSC in vitro. The anticancer activity of OSC was also examined using a xenograft growth assay in vivo. Furthermore, serum metabolomics analysis by GC-MS was done to detect alterations in the metabolic profile. Next, expression of GLS1 and GLUD1, the key enzymes in glutamine metabolism, was evaluated using RT-PCR and western blot. α-KG and NADH metabolites were assessed by ELISA. Mitochondrial functions and morphology were evaluated using the JC-1 probe and transmission electron microscopy, respectively. The ATP production rate in mitochondria of cells with OSC treatment was determined using a Seahorse XFe24 Analyzer. RESULTS OSC selectively reduced the proliferation of A549 and H460 cells. OSC triggered G2/M cell cycle arrest and decreased the cell clone formation. A mouse xenograft model revealed that OSC inhibited tumor growth in vivo. Findings of serum metabolomics analyses indicated that the anticancer function of OSC was related to disorders of glutamine metabolism. Such a speculation was further verified by the expression level of GLUD1, which was downregulated by OSC treatment. Concentrations of the related metabolites α-KG and NADH were reduced in response to OSC treatment. Moreover, OSC led to disorganization of the mitochondrial ultrastructure and a decrease in mitochondrial membrane potential. OSC also decreased ATP production via oxidative phosphorylation (OXPHOS) but did not affect glycolysis in NSCLC cells. CONCLUSION The key role of OSC in mitochondrial energy metabolism in NSCLC cells is to suppress tumor development and cell proliferation downregulating GLUD1 to inhibit the glutamine/glutamate/α-KG metabolic axis and OXPHOS. It indicats that OSC might be a potential natural agent for personalized medicine and an anticancer metabolic modulator in NSCLC chemotherapy.

Abstract
Mushrooms provide a reliable source of bioactive compounds and have numerous nutritional values, which is one of the reasons why they are widely used for culinary purposes. They may also be a remedy for several medical conditions, including cancer diseases. Given the constantly increasing number of cancer incidents, the great anticancer potential of mushrooms has unsurprisingly become an object of interest to researchers. Therefore, this review aimed to collect and summarize all the available scientific data on the anti-cancer activity of mushroom extracts. Our research showed that mushroom extracts from 92 species, prepared using 12 different solvents, could reduce the viability of 38 various cancers. Additionally, we evaluated different experimental models: in vitro (cell model), in vivo (mice and rat model, case studies and randomized controlled trials), and in silico. Breast cancer proved to be sensitive to the highest number of mushroom extracts. The curative mechanisms of the studied mushrooms consisted in: inhibition of cancer cell proliferation, unregulated proportion of cells in cell cycle phases, induction of autophagy and phagocytosis, improved response of the immune system, and induction of apoptotic death of cells via upregulation of pro-apoptotic factors and downregulation of anti-apoptotic genes. The processes mainly involved the expression of caspases -3, -8, -9, AKT, p27, p53, BAX, and BCL2. The quoted results could lead to the classification of mushrooms as nutraceuticals used to prevent a variety of disorders or to support treatment of cancer diseases.

Abstract
There are abundant sources of anticancer drugs in nature that have a broad prospect in anticancer drug discovery. Natural compounds, with biological activities extracted from plants and marine and microbial metabolites, have significant antitumor effects, but their mechanisms are various. In addition to providing energy to cells, mitochondria are involved in processes, such as cell differentiation, cell signaling, and cell apoptosis, and they have the ability to regulate cell growth and cell cycle. Summing up recent data on how natural products regulate mitochondria is valuable for the development of anticancer drugs. This review focuses on natural products that have shown antitumor effects via regulating mitochondria. The search was done in PubMed, Web of Science, and Google Scholar databases, over a 5-year period, between 2015 and 2020, with a keyword search that focused on natural products, natural compounds, phytomedicine, Chinese medicine, antitumor, and mitochondria. Many natural products have been studied to have antitumor effects on different cells and can be further processed into useful drugs to treat cancer. In the process of searching for valuable new drugs, natural products such as terpenoids, flavonoids, saponins, alkaloids, coumarins, and quinones cover the broad space.

Abstract
Hydroxysafflor yellow A (HSYA) is a water-soluble component of the safflower (Carthamus tinctorius), and research has revealed that HSYA exhibits antitumor effects. In the present study, the effects of HSYA on the autophagy of a Hep-G2 liver cancer cell line, as well as the underlying mechanisms, were investigated. Hep-G2 cells were treated with HSYA and the viability of cells was measured using an MTT assay. Western blotting and immunofluorescence assays were performed to determine the expression of light chain 3 II (LC3-II) and p62, as well as the autophagy regulators Beclin 1 and ERK1/2. Transmission electron microscopy was performed to observe the formation of autophagosomes. The combined effects of HSYA and the autophagy inhibitor chloroquine (CQ) were also determined. The results revealed that the viability of Hep-G2 cells decreased with increasing concentrations of HSYA. Furthermore, LC3-II expression increased significantly and the level of p62 decreased significantly in the HYSA group compared with the control group. Additionally, an increase in Beclin 1 expression and a decrease in phosphorylated-ERK1/2 expression was observed in Hep-G2 cells treated with HYSA. Following treatment with CQ and HSYA, a significant increase in the viability of Hep-G2 cells was observed compared with the HSYA group. Collectively, the results indicated that HSYA induced autophagy by promoting the expression of Beclin 1 and inhibiting the phosphorylation of ERK in liver cancer cells. Therefore, HSYA may serve as a potential therapeutic agent for liver cancer.
