Jang AY, Kim M, Rod-In W, Nam YS, Yoo TY, Park WJ. In vitro immune-enhancing effects of Platycodon grandiflorum combined with Salvia plebeian via MAPK and NF-κB signaling in RAW264.7 cells. PLoS One 2024; 19:e0297512. [PMID: 38306362 PMCID: PMC10836713 DOI: 10.1371/journal.pone.0297512] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Accepted: 12/30/2023] [Indexed: 02/04/2024] Open
Abstract
The immune-enhancing activity of the combination of Platycodon grandiflorum and Salvia plebeian extracts (PGSP) was evaluated through macrophage activation using RAW264.7 cells. PGSP (250-1000 μg/mL) showed a higher release of NO in a dose-dependent manner. The results showed that PGSP could significantly stimulate the production of PGE2, COX-2, TNF-α, IL-1β, and IL-6 in RAW264.7 cells and promote iNOS, COX-2, TNF-α, IL-1β, IL-4, and IL-6 mRNA expression. Western blot analysis demonstrated that the protein expression of iNOS and COX-2 and the phosphorylation of ERK, JNK, p38, and NF-κB p65 were greatly increased in PGSP-treated cells. PGSP also promoted the phagocytic activity of RAW264.7 cells. All these results indicated that PGSP might activate macrophages through MAPK and NF-κB signaling pathways. Taken together, PGSP may be considered to have immune-enhancing activity and might be used as a potential immune-enhancing agent.

Kim JH, Kim J. Comprehensive analysis of the chloroplast genome and phylogenetic relationships of Sasa quelpaertensis Nakai. Mitochondrial DNA B Resour 2024; 9:88-93. [PMID: 38222981 PMCID: PMC10786426 DOI: 10.1080/23802359.2023.2301017] [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: 08/21/2023] [Accepted: 12/27/2023] [Indexed: 01/16/2024] Open
Abstract
Jeju-Joritdae (Sasa quelpaertensis Nakai) is a broad-leaved bamboo grass endemic to Mount Halla, Jeju Island, South Korea. In this study, we report the complete chloroplast genome sequence of S. quelpaertensis. Its chloroplast genome is 139,730 bp in size and consists of a large single-copy (LSC, 83,351 bp) region, one small single-copy (SSC, 12,788 bp) region, and two inverted repeats (IRs, 21,796 bp each). The chloroplast genome of S. quelpaertensis encodes 131 genes, including 86 protein-coding, 37 tRNA, and 8 rRNA genes. The overall GC content of the S. quelpaertensis chloroplast genome is 38.86%. Phylogenetic analysis using the chloroplast genome sequence showed that S. quelpaertensis is closely related to Sasa veitchii and Sasella kogasensis. These findings provide valuable genomic resources for future studies of the Sasa genus in South Korea and other countries encompassing its distribution area.

Luo M, Zheng Y, Tang S, Gu L, Zhu Y, Ying R, Liu Y, Ma J, Guo R, Gao P, Zhang C. Radical oxygen species: an important breakthrough point for botanical drugs to regulate oxidative stress and treat the disorder of glycolipid metabolism. Front Pharmacol 2023; 14:1166178. [PMID: 37251336 PMCID: PMC10213330 DOI: 10.3389/fphar.2023.1166178] [Citation(s) in RCA: 14] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Accepted: 04/21/2023] [Indexed: 05/31/2023] Open
Abstract
Background: The incidence of glycolipid metabolic diseases is extremely high worldwide, which greatly hinders people's life expectancy and patients' quality of life. Oxidative stress (OS) aggravates the development of diseases in glycolipid metabolism. Radical oxygen species (ROS) is a key factor in the signal transduction of OS, which can regulate cell apoptosis and contribute to inflammation. Currently, chemotherapies are the main method to treat disorders of glycolipid metabolism, but this can lead to drug resistance and damage to normal organs. Botanical drugs are an important source of new drugs. They are widely found in nature with availability, high practicality, and low cost. There is increasing evidence that herbal medicine has definite therapeutic effects on glycolipid metabolic diseases. Objective: This study aims to provide a valuable method for the treatment of glycolipid metabolic diseases with botanical drugs from the perspective of ROS regulation by botanical drugs and to further promote the development of effective drugs for the clinical treatment of glycolipid metabolic diseases. Methods: Using herb*, plant medicine, Chinese herbal medicine, phytochemicals, natural medicine, phytomedicine, plant extract, botanical drug, ROS, oxygen free radicals, oxygen radical, oxidizing agent, glucose and lipid metabolism, saccharometabolism, glycometabolism, lipid metabolism, blood glucose, lipoprotein, triglyceride, fatty liver, atherosclerosis, obesity, diabetes, dysglycemia, NAFLD, and DM as keywords or subject terms, relevant literature was retrieved from Web of Science and PubMed databases from 2013 to 2022 and was summarized. Results: Botanical drugs can regulate ROS by regulating mitochondrial function, endoplasmic reticulum, phosphatidylinositol 3 kinase (PI3K)/protein kinase B (AKT), erythroid 2-related factor 2 (Nrf-2), nuclear factor κB (NF-κB), and other signaling pathways to improve OS and treat glucolipid metabolic diseases. Conclusion: The regulation of ROS by botanical drugs is multi-mechanism and multifaceted. Both cell studies and animal experiments have demonstrated the effectiveness of botanical drugs in the treatment of glycolipid metabolic diseases by regulating ROS. However, studies on safety need to be further improved, and more studies are needed to support the clinical application of botanical drugs.

Immunomodulatory Effect of Sasa quelpaertensis Leaves Fermentation Products in Mice. FERMENTATION 2021. [DOI: 10.3390/fermentation7030142] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/17/2022] Open
Abstract
The purpose of this study was to enhance the immune-enhancing activity of mushroom strains through fermentation to promote food use of leaf extracts of S. quelpaertensis containing β-glucan. We evaluated the immunomodulatory effect of extracts from fermented S. quelpaertensis leaves (SQGL, SQHE, SQPL). S. quelpaertensis leaves fermentation products were prepared by using mushroom mycelia (Ganoderma lucidum, Hericium erinaceum, Phellinus linteus). The content of β-glucan, a major substance in S. quelpaertensis leaves fermentation products, was 3.73 ± 0.50 mg/mL in the extract (SQ) of S. quelpaertensis leaves. The fermented mushrooms, SQGL, were the highest at 5.57 ± 0.86 mg/100 mL, followed by SQHE and SQPL, and the β-glucan content of all of the glucan was >75.3%. To test the immune activity, S. quelpaertensis leaf fermentation products were administered to mice at different doses (60, 160, and 360 mg/kg) for two weeks. Th cell and macrophage populations were found to increase significantly at all three doses compared to the negative control after two weeks. SQGL and SQHE were highest at 160 mg/kg, and SQPL showed the highest Th cell proliferation at 60 mg/kg. In addition, the production of IFN-γ, IL-4, IL-10, and nitric oxide was significantly higher than that of the negative control after two weeks. In particular, an increase was seen at a low concentration of 60 mg/kg. Therefore, the S. quelpaertensis leaf fermentation product can be very useful as a functional ingredient for enhancing immunity.
