[PMID: 37844741 DOI: 10.1016/j.jep.2023.117284] [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: 08/22/2023] [Revised: 10/03/2023] [Accepted: 10/04/2023] [Indexed: 10/18/2023]
Abstract
ETHNOPHARMACOLOGY RELEVANCE Sanghuangporus vaninii (S. vaninii), as a traditional large medicinal fungus, has a history of more than 2000 years in Chinese history and has been widely used to treat female diseases such as vaginal discharge, amenorrhea, and uterine bleeding, and recent pharmacological studies have also found that it has antioxidant, anti-inflammatory, and anti-tumor physiological activity, which has received more and more attention. AIM OF THE STUDY The objective was to evaluate cytotoxicity and the acute, subacute toxicity, and in vitro antioxidant activity of S. vaninii crude polysaccharide (SVP). MATERIALS AND METHODS The monosaccharide composition of SVP was determined by HPLC (high-performance liquid chromatography). The cytotoxicity of different concentrations of SVP on three types of cells (HT-22, Kupffer macrophages, HEK293) was assessed using CCk-8. The acute toxicity in vivo was evaluated for 14 days after the administration of SVP (2500,5000, or 10,000 mg/mL). For the evaluation of subacute toxicity, mice were daily treated for 28 days with SVP (2500,5000, or 10,000 mg/mL). In addition, DPPH, hydroxyl radical, and superoxide anion radical were used to evaluate the in vitro antioxidant activity of SVP. RESULTS SVP was not toxic in all three cell lines tested. In vitro antioxidant tests on the extracts showed that SVP possessed a strong antioxidant capacity in vitro. In the acute study, the no-observed-adverse-effect level (NOAEL) in male and female rats was 10,000 mg/kg body weight. There were also no deaths or severe toxicity associated with SVP in subacute studies. However, SVP treatment had a decreasing effect on body weight in mice of both sexes (2500, 5000, and 10000 mg/kg). At doses (5000 and 10,000 mg/kg), SVP had a reduced effect on food intake in both male and female mice. In addition, there were significant effects on organ coefficients of the liver, lung, and kidney. Hematological analysis showed significantly lower LYM (%) values in mice of both sexes, with significantly lower MCH (pg) values obtained in males (5000 mg/kg and 10000 mg/kg) and higher GRAN (%) values in females. In addition, the RDW-SD (fL) values were significantly lower in the male mice given the highest dose. Biochemical tests showed that there were no significant changes in ALT, AST, TP, and Cr levels after SVP treatment. In histopathological analysis, mild liver toxicity was observed in both female mice treated with 10,000 mg/kg SVP. CONCLUSION The extract of SVP showed a predominance of polysaccharide compounds, with non-toxic action in vivo. Our approach revealed SVP on the chemical composition and suggests a high margin of safety in the popular use of medicinal fungi. In conclusion, our results suggest that SVP is safe, and can be used as health care products and food.

Abstract
BACKGROUND Melanoma is the most aggressive form of skin cancer. Melanoma stem cells (MSCs) are one of the driving forces of melanoma invasion and metastasis. Therefore, it is of great significance to explore the mechanisms that maintain the stemness of MSCs. In this study, CD147-positive (CD147+) MSCs derived from A375 cell line were characterized. METHODS Side population (SP) and non-SP cells were sorted from A375 cells. Quantitative real-time polymerase chain reaction and Western blot analysis were conducted to determine the expression of CD147 in SP and non-SP cells. Subsequently, CD147+ and CD147-negative (CD147-) cells were isolated from SP cells. Stem cell characteristics and metastatic potential of CD147+/- antigen-presenting cells were identified by sphere-forming, wound-healing, and transwell assays. Western blot analysis was performed to evaluate the protein levels of transforming growth factor-beta1 (TGFβ1) and neurogenic locus notch homolog protein 1 (Notch1) signaling pathway. Xenograft tumor experiments were conducted to investigate the tumorigenic capacity of CD147+ cells in vivo. RESULTS CD147 was highly expressed in SP cells of A375 cell line. CD147+ cells have stronger abilities for sphere forming, migration, and invasion in vitro. The protein levels of TGFβ1, notch1, jagged1, and Hes1 were higher in CD147+ cells than in CD147- cells. Moreover, the CD147+ cells showed stronger tumorigenic and metastatic potential in vivo. CONCLUSION SP cells of A375 cell line expressed high levels of CD147, and CD147+ SP cells possessed much stronger stem-like characteristics and motility, which is linked to the activation of TGFβ and notch pathways.

Abstract
Sanghuangporus vaninii is a medicinal mushroom, which has been used as a treatment for various diseases; however, the therapeutic potential and mechanism of action of S. vaninii in colorectal cancer (CRC) remain unknown. Herein, human colon adenocarcinoma cells were used to analyze the anti-CRC effects of the purified polysaccharide of S. vaninii (SVP-A-1) in vitro. In SVP-A-1-treated B6/JGpt-Apcem1Cin (Min)/Gpt male (ApcMin/+) mice, 16S rRNA sequencing was performed on cecal feces, metabolites were examined in serum, and LC-MS/MS protein detection was performed in colorectal tumors. Protein changes were further confirmed by various biochemical detection methods. Water-soluble SVP-A-1 with a molecular weight of 22.5 kDa was first obtained. SVP-A-1 prevented gut microbiota dysbiosis related to metabolic pathways of L-arginine biosynthesis, increased L-citrulline levels in the serum of ApcMin/+ mice, mediated L-arginine synthesis, and improved antigen presentation in dendritic cells and activated CD4+ T cells; the resulting Th1 cells released IFN-γ and TNF-α to act on tumor cells and promoted the sensitivity of tumor cells to cytotoxic T lymphocytes. In summary, SVP-A-1 exerted anti-CRC effects and has excellent potential for CRC treatment.

Non-targeted metabonomics and transcriptomics revealed the mechanism of mulberry branch extracts promoting the growth of Sanghuangporus vaninii mycelium. Front Microbiol 2022; 13:1024987.

Abstract
Sanghuangprous vaninii is a wood-inhabiting fungus, and its mycelium and fruiting body show excellent medicinal values. Mulberry is one of the major hosts of S. vaninii, however, the mechanism of mulberry affecting the growth of S. vaninii has not been reported. In the present study, a mulberry-inhabiting strain of S. vaninii was selected to explore the effects of mulberry branch extracts (MBE) on the growth of the strain. Results showed that MBE could significantly promote the growth of S. vaninii mycelium at the concentration of 0.2 g/l. After 16 days of liquid culture, the dry weight of mycelium in 0.2 g/l MBE medium was higher by three times compared with that in the control. The non-targeted metabonomic analysis of the culture medium at different culture times and concentrations was conducted to find the key components in MBE that promoted the growth of S. vaninii mycelium. Under the different concentrations of MBE culture for 10 and 16 days, 22 shared differential metabolites were identified. Next, in accordance with the peak value trend of these metabolites, HPLC–MS and liquid culture validation, four components derived from MBE (i.e., scopoletin, kynurenic acid, 3,5-dihydroxybenzoic acid and 2,4-dihydroxybenzoic acid) could significantly increase the growth rate of mycelium at the concentration of 2 mg/l. Transcriptomic and qRT-PCR analyzes showed that MBE could upregulate hydrolase-related genes, such as serine–glycine–asparaginate–histidine (SGNH) hydrolase, alpha-amylase, poly-beta-hydroxybutyrate (PHB) depolymerase, glycosyl hydrolase family 61, cerato-platanin protein and Fet3, which might enhance the nutrient absorption ability of S. vaninii. Importantly, MBE could significantly increase the content of harmine, androstenedione and vesamicol, which have been reported to possess various medicinal effects. Results suggested that MBE could be an excellent additive for liquid culture of S. vaninii mycelium, and these hydrolase-related genes also provided candidate genes for improving the nutrient absorption capacity of S. vaninii.

[PMID: 36655066 PMCID: PMC9834848 DOI: 10.1002/fsn3.3080] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2021] [Revised: 08/31/2022] [Accepted: 09/15/2022] [Indexed: 01/21/2023] Open
Abstract
The alcohol extracts of Chinese bayberry (Myrica rubra) branches (MRBE) are rich in flavonoids which have a variety of medicinal benefits, but their effects on human HepG2 were unknown. In this study, the effects of MRBE on HepG2 cell growth and its potential for inhibiting cancer were explored. The results displayed that MRBE inhibited HepG2 proliferation both by arresting cells in S phase and promoting apoptosis. Quantitative reverse-transcription PCR (qRT-PCR), western blotting, and immunofluorescence showed that MRBE induced S-phase arrest by upregulating p21, which in turn downregulated cyclin and cyclin-dependent kinase messenger RNA (mRNA) and protein. Apoptosis was induced by blocking the expression of BCL-2 and suppression of the Raf/ERK1 signaling pathways. These results indicated that MRBE may have the potential for treatment of human liver cancer, highlighting novel approaches for developing new pharmacological tools for the treatment of this deadly type cancer. Meanwhile, it provides a new direction for the medicinal added values of Chinese bayberry, which helped to broaden the diversified development of its industry chain.

Abstract
This study assessed BMSC’s effect on melanoma cells. The melanoma A375 cells were assigned into blank group, BMSC group, ERK agonist group, AKT agonist group, ERK + AKT agonist group and ERK + AKT repressor group followed by analysis of VEGF expression, cell apoptotic rate, and
the expression of MEK/ERK and PI3K/AKT signal proteins. ERK and AKT agonist group showed highest VEGF expression, lowest cell apoptosis and Bcl-2 and Bcl-2/Bax expression as well as highest MEK/ERK and PI3K/AKT signaling proteins followed by ERK agonist group and AKT agonist group. The apoptosis
of melanoma cells could be prompted by BMSC which might be through restraining the activity of MEK/ERK and PI3K/AKT signal pathway. In conclusion, the apoptosis of melanoma cells is prompted by BMSC through restraining the activity of MEK/ERK and PI3K/AKT signal pathway, indicating that BMSC
might be used as a novel approach for the treatment of melanoma.
