Abstract
Introduction Inonotus hispidus, commonly referred to as the Sanghuang mushroom, is a species that is consumed as a tea. To date, this is the only species of the same fungus that has been successfully cultivated. Methods A single-factor test was conducted using Inonotus hispidus MS-5 and MS-9 as test materials. The response surface methodology was adopted to design and optimise the liquid fermentation medium for them. Results As indicated in the results, the optimum fermentation conditions for MS-5 include 24.09 g/L glucose, 7.88 g/L yeast extract, 0.99 g/L dandelion powder, 1.5 g MgSO4, 2 g KH2PO4, 0.01 g vitamin B1, and 1 L deionized water; the optimum fermentation conditions for MS-9 include 24.64 g/L glucose, 7.77 g/L yeast extract, 0.98 g/L dandelion powder, 1.5 g MgSO4, 2 g KH2PO4, 0.01 g vitamin B1, and 1 L deionized water. Under such conditions, the mycelial biomass (dry weight) values were able to reach 16.02 g/L and 14.91 g/L for MS-5 and MS-9, respectively, which were 1.6 and 1.54 times those measured before optimization. Discussion As revealed in the antioxidant and anticancer experiment, Inonotus hispidus exopolysaccharides has corresponding functional effects at the cellular level. This research optimised the liquid culture formulation of Inonotus hispidus and demonstrated that the function of it as a traditional Sanghuang herbal tea is well-documented.

Han C, Bao H. Therapeutic effects and mechanisms of Inonotus hispidus extract and active monomer compounds in a rat mammary gland hyperplasia model. JOURNAL OF ETHNOPHARMACOLOGY 2024; 319:117274. [PMID: 37797875 DOI: 10.1016/j.jep.2023.117274] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Revised: 09/18/2023] [Accepted: 10/02/2023] [Indexed: 10/07/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Inonotus hispidus is the traditional Chinese medicine Sanghuang. Since ancient times, Sanghuang has been documented to be used in the treatment of female breast diseases. However, the pharmacological mechanism of Sanghuang in the treatment of mammary gland hyperplasia (HMG) remains unclear. AIM OF THE STUDY The ethyl acetate extract of the aging fruiting body of I. hispidus (IEAE) was used to study the pharmacological mechanism of IEAE in the treatment of HMG using non-targeted metabolomics. MATERIALS AND METHODS The HMG rat model was established, and serum metabolomics was used to study the potential therapeutic mechanism of IEAE for HMG. RESULTS IEAE has obvious therapeutic effect on HMG model rats, and no obvious adverse reactions were observed. Non-targeted metabolomics showed that after IEAE intervention, the upstream metabolite D-erythrose 4-phosphate was significantly downregulated, aromatic amino acids such as tryptophan, tyrosine, and phenylalanine were downregulated, and the downstream metabolites N-acetyl-L-glutamate and L-proline were significantly upregulated. After an intervention with yakuchinone A, non-targeted metabolomics analyses demonstrated that yakuchinone A restored tetrahydrocorticosterone, cortisol, and etiocholanolone to normal levels, estriol was significantly upregulated, and steroid hormone biosynthesis was significantly activated. CONCLUSION IEAE was shown to have a good therapeutic effect on HMG in a rat model without adverse reactions. The mechanism of action was mainly based on the biosynthesis of amino acids. Small molecule metabolites such as D-erythrose 4-phosphate, N-acetyl-L-glutamate, and L-proline may be potential targets for IEAE in the treatment of HMG. Yakuchinone A is one of the main active components of IEAE, and plays a role by promoting the steroid hormone biosynthesis pathway. Estriol may be a potential target for the treatment of HMG with yakuchinone A, providing a new concept for clinical treatment of HMG.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Inonotus hispidus (I. hispidus), known as shaggy bracket, has been used extensively in China and some East Asian countries as a traditional medicinal macrofungus to treat difficult diseases, such as diabetes, gout, and arthritis. Modern pharmacological research has shown that I. hispidus has an important application value in antitumor treatment. However, the main anti-cervical cancer activity substances from its mycelia and its mechanisms are still not clear. AIMS OF THE STUDY To enrich the germplasm resources of I. hispidus, to reveal the antitumor activity of the extract from the mycelium of I. hispidus against cervical cancer, and to preliminarily analyze its action mechanism. MATERIALS AND METHODS The SH3 strain was isolated from wild fruiting bodies and identified by morphology and molecular biology. The antitumor active component from the mycelium of I. hispidus was isolated and identified with liquid chromatography-tandem mass spectrometry. The cell viability was assessed by MTT assay. The cell cycle distribution, apoptotic cell detection, and mitochondrial membrane potential were detected by flow cytometer. The expression of apoptosis-related proteins was assessed by Western blotting. The inhibition of tumor growth in vivo was assessed by a mouse xenograft model. RESULTS The SH3 strain was isolated and identified as a new strain of I. hispidus. The antitumor active component containing cyclic peptides from the mycelium of I. hispidus (CCM) was isolated for the first time. In addition, we found that CCM had a strong inhibitory effect on HeLa proliferation in vitro and in vivo. Mechanically, the CCM blocked the cell cycle at the G0/G1 phase, decreased the mitochondrial membrane potential, and eventually promoted apoptosis of HeLa cells through the mitochondria-mediated pathway by upregulating the expression levels of Bax, cytochrome C, cleaved caspase-9, and cleaved caspase-3 and downregulating the expression level of Bcl-2. CONCLUSIONS Our study not only enriches the strain resources of I. hispidus but also confirms that the mycelium of this strain has active components that can inhibit cervical cancer. This is highly significant for the development of active drugs and drug lead molecules for treating cervical cancer.

Abstract
Inonotus hispidus mainly growing in broad-leaved trees, including Morus alba, Fraxinus mandshurica, and Ulmus macrocarpa etc. The fruiting body of I. hispidus growing in M. alba (hereafter as MA) is used as a traditional Chinese medicine "Sanghuang". However, differences between the genetic material basis of I. hispidus growing in other tree species have not been reported. Therefore, in this paper, the genomic comparison between MA and I. hispidus growing in F. mandshurica (hereafter as FM) were studied. The whole genome of MA monokaryon was sequenced by Illumina combined with Pac Bio platform. Next, genome assembly, genome component prediction and genome functional annotation were performed. Comparative genomics analysis was performed between FM monokaryon and MA monokaryon, using MA as the reference. The results showed that, MA had 24 contigs with a N50 length of 2.6 Mb. Specifically, 5,342, 6,564, 1,595, 383 and 123 genes were annotated from GO, KEGG, KOG, CAZymes and CYP450, respectively. Moreover, comparative genomics showed that, the coding genes and total number of genes annotated in different databases of FM were higher than that of MA. This study provides a foundation for the medicinal application of FM as MA from the perspective of genetic composition.

Abstract
The use of ultrasound-assisted extraction (UAE) of bioactive compounds has been increasing because it is a good alternative to the conventional extraction methods. UAE was used to maximize total polyphenol content (TPC), 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging capacity, and ferric reducing antioxidant power (FRAP) of the mushroom Inonotus hispidus using response surface methodology (RSM). Firstly, the effect of 40% (v/v) ethanol and 80% (v/v) methanol on the TPC, DPPH scavenging capacity, and FRAP was evaluated. The ethanolic extracts showed a significantly higher (p < 0.0001) TPC, DPPH scavenging capacity, and FRAP than the methanolic extracts. The best condition to produce an extract with the higher TPC and antioxidant activity was achieved when using 40% (v/v) ethanol, a ratio of 75 mL/g, and an extraction time of 20 min. The chromatographic profile of the extract obtained in the optimized condition revealed that hispidin is the main polyphenol present in the extracts of I. hispidus, representing, together with hispidin-like compounds, the majority of the phenolic compounds (159.56 µg/g DW out of 219.01 µg/g DW). The model allowed us to optimize the conditions to maximize the extraction of phenolic compounds with antioxidant activity from I. hispidus, demonstrating its potential as a source of antioxidant compounds, with possible industrial, pharmaceutical, and food applications.

Abstract
Inonotus hispidus is a traditional medicinal that grows in Northeast China and produces various economically important compounds, including polysaccharide compounds and terpenoids; triterpenoid saponins is the main bioactive component. Our research group has found that the accumulation of triterpenoid was affected by exogenous inducers. Experimental results showed that treatment with methyl jasmonate (MeJA) and oleic acid significantly increased the triterpenoid content of I. hispidus. However, how exogenous inducers enhance production of secondary metabolites in I. hispidus is not well understood. In this study, metabolite changes were further investigated with UPLC-TOF/MS following exogenous inducer treatment. As a result, a total of eight types of triterpenoids in I. hispidus were identified. The RNA-seq analysis was used to evaluate the effects of exogenous inducers on the expression of triterpenoid-synthesis-related genes in I. hispidus in liquid fermentation. This study is the first exploration to profile the transcriptome of I. hispidus after adding exogenous inducers; the generated data and gene will facilitate further molecular studies on the physiology and metabolism in this fungi. By comparative transcriptomic analysis, a series of candidate genes involved in the biosynthetic pathway of triterpenoids are identified, providing new insights into their biosynthesis at the transcriptome level.

Abstract
Inonotus hispidus mushroom is a traditional medicinal fungus with anti-cancer, antioxidation, and immunomodulatory activities, and it is used in folk medicine as a treatment for indigestion, cancer, diabetes, and gastric illnesses. Although I. hispidus is recognized as a rare edible medicinal macrofungi, its genomic sequence and biosynthesis potential of secondary metabolites have not been investigated. In this study, using Illumina NovaSeq combined with the PacBio platform, we sequenced and de novo assembled the whole genome of NPCB_001, a wild I. hispidus isolate from the Aksu area of Xinjiang Province, China. Comparative genomic and phylogenomic analyses reveal interspecific differences and evolutionary traits in the genus Inonotus. Bioinformatics analysis identified candidate genes associated with mating type, polysaccharide synthesis, carbohydrate-active enzymes, and secondary metabolite biosynthesis. Additionally, molecular networks of metabolites exhibit differences in chemical composition and content between fruiting bodies and mycelium, as well as association clusters of related compounds. The deciphering of the genome of I. hispidus will deepen the understanding of the biosynthesis of bioactive components, open the path for future biosynthesis research, and promote the application of Inonotus in the fields of drug research and functional food manufacturing.

Abstract
Acute inflammation and hyperuricemia are associated with gouty arthritis. As an edible and therapeutic mushroom, Sanghuangporus vaninii (SV) has an inhibitory effect on tumorigenesis, and Inonotus hispidus (IH) exhibits anti-tumor, anti-inflammatory, and antioxidant properties. In this study, uric acid (UA) and xanthine oxidase (XOD) levels in hyperuricemic mice were examined to determine the regulatory effects of SV and IH. SV and IH reversed the pathogenic state of elevated UA levels in the serum and reduced levels of XOD in the serum and liver of mice with hyperuricemia. SV and IH affected the inflammatory response in rats with acute gouty arthritis. Compared to vehicle-treated rats, monosodium urate crystals (MSU) increased the swelling ratio of the right ankle joints. SV and IH administration significantly reduced swelling and inflammatory cell infiltration. SV reduced the levels of interleukin-8 (IL-8) and chemokine ligand-2 (CCL-2), whereas IH reduced the levels of matrix metalloproteinase-9 (MMP-9), CCL-2, and tumor necrosis factor-α (TNF-α), which were confirmed in articular soft tissues by immunohistochemistry. In summary, our data provide experimental evidence for the applicability of SV and IH in gouty arthritis and hyperuricemia treatment.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The mushroom Inonotus hispidus is traditional Chinese medicine, which has been used to treat tumor illness for a long history in China. Our previous research found that I. hispidus petroleum ether extract (IPE) has significant anti-tumor activity. However, the potential anti-tumor regulatory pathways and targets of I. hispidus remain unclear. OBJECTIVE The present study was envisaged to explore the key regulators responsible for anti-tumor of IPE using whole transcriptome and proteome analysis in H22 tumor-bearing mice model. MATERIALS AND METHODS The model of H22 tumor-bearing mice was constructed according to the histopathological data and biochemical parameters. The isolated tumor tissues of different treatment groups were subjected to transcriptomic and proteomic analysis. An integrated approach of RNA-Seq, proteomics, and system biology analysis was used to identify key regulators involved in antitumor pathways. The analyzed differential expression patterns were supported by gene and protein expression studies. RESULTS These results indicated that 957 differentially expressed genes and 405 proteins were identified in the tumor tissue of different treatment groups through RNA-Seq and liquid chromatography with tandem mass spectrometry-based proteomic analysis, respectively. The combined omics analysis revealed five critical genes/proteins, including Lilrb4a, Nrp1, Gzma, Gstt1, and Pdk4 that could play a role in antitumor pathways. Furthermore, Lilrb4a, Nrp1, Gzma, Gstt1 and Pdk4 genes/proteins, as key regulators of the anti-tumor effect of IPE, were verified by qRT-PCR and western blotting methods, respectively. CONCLUSION Our study provides new ideas for analyzing the antitumor mechanism of IPE from the point of view of gene and protein expression and will encourage further development of the I. hispidus pharmaceutical industry.

Abstract
Inonotus hispidus (I. hispidus) is a medicinal macrofungus that plays a key role in anti-tumor and antioxidant functions. To further understand and enhance the value of I. hispidus, we performed whole-genome sequencing and an analysis of its strain for the first time. I. hispidus was sequenced using the Illumina NovaSeq high-throughput sequencing platform. The genome length was 35,688,031 bp and 30 contigs, with an average length of 1,189,601.03 bp. Moreover, database alignment annotated 402 CAZyme genes and 93 functional genes involved in regulating secondary metabolites in the I. hispidus genome to find the greatest number of genes involved in terpenes in that genome, thus providing a theoretical basis for its medicinal value. Finally, the phylogenetic analysis and comparative genomic analysis of single-copy orthologous protein genes from other fungi in the same family were conducted; it was found that I. hispidus and Sanghuangporus baumii have high homology. Our results can be used to screen candidate genes for the nutritional utilization of I. hispidus and the development of high-yielding and high-quality I. hispidus via genetic means.

Inonotus hispidus Protects against Hyperlipidemia by Inhibiting Oxidative Stress and Inflammation through Nrf2/NF-κB Signaling in High Fat Diet Fed Mice. Nutrients 2022; 14:nu14173477. [PMID: 36079733 PMCID: PMC9460493 DOI: 10.3390/nu14173477] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Revised: 08/17/2022] [Accepted: 08/21/2022] [Indexed: 12/28/2022] Open
Abstract
Obesity is frequently associated with dysregulated lipid metabolism and lipotoxicity. Inonotus hispidus (Bull.: Fr.) P. Karst (IH) is an edible and medicinal parasitic mushroom. In this study, after a systematic analysis of its nutritional ingredients, the regulatory effects of IH on lipid metabolism were investigated in mice fed a high-fat diet (HFD). In HFD-fed mice, IH reversed the pathological state of the liver and the three types of fat and significantly decreased the levels of low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), triglycerides (TG), and leptin (LEP) and increased the level of high-density liptein cholesterol (HDL-C) in serum. Meanwhile, IH ameliorated liver damage by reducing alanine aminotransferase (ALT), aspartate aminotransferase (AST), interleukin (IL)-1β, IL-6, tumor necrosis factor-alpha (TNF-α), and plasminogen activator inhibitor-1 (PAI-1) levels in the liver and serum. Compared with HFD-fed mice, IH significantly modulated the gut microbiota, changed the relative abundances of microflora at different taxonomic levels, and regulated lipid levels. The results showed that 30 differential lipids were found. Results from Western blotting confirmed that IH regulated the nuclear factor erythroid-2 related factor 2 (Nrf2)/nuclear factor-kappa B (NF-κB) signaling pathway and oxidative stress. This study aimed to provide experimental evidence for the applicability of IH in obesity treatment.

The regular pattern of metabolite changes in mushroom Inonotus hispidus in different growth periods and exploration of their indicator compounds. Sci Rep 2022; 12:14354. [PMID: 35999354 PMCID: PMC9399111 DOI: 10.1038/s41598-022-18631-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2021] [Accepted: 08/16/2022] [Indexed: 11/09/2022] Open
Abstract
Inonotus hispidus is a valuable and rare edible and medicinal mushroom with extremely high nutritional and medicinal value. However, there is no holistic insight to elucidate the molecular basis of the differentiated usage and accurate annotation of physiological maturity to fluctuating yields and quality. This study aimed to figure out the fruiting bodies' metabolites change regulation and potential maturating indicators to distinguish different quality I. hispidus. We applied non-targeted ultra-high performance liquid chromatography and high-resolution mass spectrometry combined and with multivariate analysis and analyzed cultivated and wild mushroom I. hispidus in different growth periods (budding, mature and aging). With the fruiting bodies maturating, 1358 metabolites were annotated, 822 and 833 metabolites abundances changed greater than or equal to 1 time from the budding period to the aging period in abundance in cultivated and wild, the total polysaccharides, crude fat, total flavonoids, and total terpenes increased at first and then decreased. Total amino acids, crude protein, and total polyphenols decreased, while the total steroids increased linearly. The change of metabolites showed certain regularity. Metabolic pathways enrichment analysis showed that these metabolites are involved in glycolysis, biosynthesis of amino acids, organic acid metabolism, glycine-serine-and-threonine metabolism, tricarboxylic acid cycle, purine metabolism, and pyrimidine metabolism. In addition, ergosterol peroxide and (22E)-ergosta-4,6,8(14),22-tetraen-3-one can be used as indicator compounds, and their contents increase linearly with the fruiting bodies of I. hispidus' physiological maturation. This comprehensive analysis will help to evaluate the edible values and facilitate exploitation in mushroom I. hispidus.

Abstract
BACKGROUND Selenium (Se) is a needed trace element for animals and humans. Many fungi have effective mechanisms to acquire, transform and accumulate Se in organic form. In this study, the effects of inorganic Se (sodium selenite) on the medicinal fungus Inonotus hispidus was investigated. RESULTS Inonotus hispidus was capable of tolerating up to 3.85 mmol L-1 selenite, at which ~85% growth inhibition was seen, with 50% growth inhibition occurring at ~1 mmol L-1 selenite. Growth in 0.29 mmol L-1 Se resulted in I. hispidus mycelium with 115 times higher Se levels compared to growth in standard media, and an organic Se content of 86% to total Se content. The influence of Se accumulation on morphological features of I. hispidus were examined by microscopic and scanning electron microscopic observation. These data revealed significant shrinkage and deformations of I. hispidus hyphae with decreased branching and collapse of clamp connections under higher Se stress. However, conidial production in I. hispidus increased dramatically. The influence of Se on mycelial growth could be recovered by reinoculation in standard media. Se accumulation had only minimal impacts on the yield of the potential selenocompounds such as amino acids, proteins and polysaccharides. By contrast, Se-enriched I. hispidus mycelium was of higher quality due to reduction in crude fat and total ash contents. CONCLUSIONS These data provide basic and applied information on the feasibility of producing selenized I. hispidus as an enriched and better quality product. © 2021 Society of Chemical Industry.

Abstract
Inonotus hispidus is a popular edible and medicinal mushroom widely used in China. I. hispidus mushroom mainly grows on five different tree species (Morus alba L., Ulmus macrocarpa Hance, Fraxinus mandshurica Rupr., Ziziphus jujuba Mill., and Malus pumila Mill.), and their fruiting bodies were all separately used in the market. However, there is no holistic insight to elucidate the molecular basis of the differentiated usage. This study aimed to investigate and compare the metabolite compositions and trace elements in I. hispidus grown on five different tree species. The metabolomic data, 8 kinds of principal components and 12 kinds of trace elements, were analyzed in this study. The results showed that the same 1353 metabolites were identified in I. hispidus grown on five different tree species, but the relative abundance was different. The principal components and trace elements contents are different, for example, polysaccharides, phenol metabolites, Ca, Na, Mg, Fe, and Mn were enriched in I. hispidus grown on M. alba, the flavonoids were enriched in Z. jujuba samples, and the steroids, terpenoids, and Zn were enriched in M. pumila samples. Further, the KEGG enrichment pathway and metabolic models were established. These findings provide a molecular basis for the unique use of the I. hispidus mushroom grown on different tree species.

JOURNAL OF ETHNOPHARMACOLOGY 2022; 285:114898. [PMID: 34906637 DOI: 10.1016/j.jep.2021.114898] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Revised: 11/30/2021] [Accepted: 12/05/2021] [Indexed: 05/26/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The mushroom Inonotus hispidus is traditional Chinese medicine, which has been used to treat tumor illness for many years in China. However, the potential anti-tumor mechanisms of I. hispidus remain unclear. OBJECTIVE This study aimed to reveal the anti-tumor mechanism of I. hispidus petroleum ether extract (IPE) on H22 tumor-bearing mice from the point of view of metabonomics. MATERIALS AND METHODS The model of H22 tumor-bearing mice was constructed according to the histopathological data and biochemical parameters, while the serum metabolomics was analyzed by non-targeted ultra-high performance liquid chromatography and high-resolution mass spectrometry (UPLC-MS/MS) to study the potential anti-tumor mechanisms of IPE. RESULTS These results indicated that IPE has significant anti-tumor effect on H22 tumor-bearing mice and no obvious adverse reactions were observed. After the intervention of IPE, the biosynthesis of cortisol and corticosterone as the metabolics in the downstream of steroid biosynthesis pathway and the biosynthesis of succinate, fumarate and malate as the metabolics in the downstream of tricarboxylic acid cycle pathway were inhibited; but the metabolic pathways of the amino acids as tryptophan, lysine degradation, alanine, aspartate and glutamate and other amino acid were activated. CONCLUSION IPE has significant anti-tumor effect in H22 tumor-bearing mice, and the anti-tumor activity of IPE is main through the regulation of energy, amino acids, and steroid hormone biosynthesis pathways expression.
