[PMID: 37862983 DOI: 10.1016/j.foodchem.2023.137692] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2023] [Revised: 09/25/2023] [Accepted: 10/05/2023] [Indexed: 10/22/2023]
Abstract
The mixtures of starch and pectin were isolated by sequential extraction of the pulp and peel of black radish taproots Raphanus sativus L. with cold, hot and acidified water, solutions of ammonium oxalate, sodium carbonate and sodium hydroxide. The polysaccharide fractions obtained with ammonium oxalate solutions from the pulp and peel of the taproots gave the highest yields. The pectin was the main polysaccharide component. The yield of pectin (calculated on dry matter) from the pulp was 9.5%, from the peel -10.5%. The polysaccharide fractions obtained from pulp with hot water and ammonium oxalate solutions were subjected to sequential enzymatic degradation by amyloglucosidase and polygalacturonase, followed by fractionation on DEAE-cellulose. NMR spectra showed that rhamnogalacturonan-I (RG-I) and galacturonan (HG) regions are in structure of pectin. RG-I has unbranched structure, since there are no signals of 2,4-rhamnose residues in NMR spectra.

Identification of intracellular activation mechanism of rhamnogalacturonan-I type polysaccharide purified from Panax ginseng leaves in macrophages and roles of component sugar chains on activity. J Nat Med 2024; 78:328-341. [PMID: 38153587 DOI: 10.1007/s11418-023-01768-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2023] [Accepted: 11/27/2023] [Indexed: 12/29/2023]
Abstract
This study aimed to investigate the mechanisms underlying intracellular signaling pathways in macrophages in relation to the structural features of rhamnogalacturonan (RG) I-type polysaccharide (PGEP-I) purified from Panax ginseng leaves. For this investigation, we used several specific inhibitors and antibodies against mitogen-activated protein kinase (MAPK), nuclear factor-kappa B (NF-κB), and pattern recognition receptors (PRRs). Furthermore, we investigated the roles of component sugar chains on immunostimulating activity through a sequential enzymatic and chemical degradation steps. We found that PGEP-I effectively induced the phosphorylation of several MAPK- and NF-κB-related proteins, such as p38, cJun N-terminal kinase (JNK), extracellular signal-regulated kinase (ERK), and p65. Particularly, immunocytochemistry analysis confirmed the PGEP-I-induced translocation of p65 into the nucleus. Furthermore, the breakdown of PGEP-I side chains and main chain during sequential enzymatic and chemical degradation reduced the PGEP-I-induced macrophage cytokine secretion activity. IL-6, TNF-α, and NO secreted by macrophages are associated with several signaling pathway proteins such as ERK, JNK, and NF-κB and several PRRs such as dectin-1, CD11b, CD14, TLR2, TLR4, and SR. Thus, these findings suggest that PGEP-I exerts potent macrophage-activating effects, which can be attributed to its typical RG-I structure comprising arabinan, type II arabinogalactan, and rhamnose-galacturonic acid repeating units in the main chain.

Abstract
A new polysaccharide, named SP800201 with Mw of 2.17 × 105 g/mol, was isolated from Saposhnikoviae Radix. The monosaccharide composition of SP800201 mainly contained Gal, GalA, Ara, and Rha. SP800201 has a core structure containing GalA as the backbone and side chains consisting of GalA, Gal, Ara and Rha. Cell and zebrafish experiments were used to explore the immunomodulatory activity of SP800201. Results of vitro RAW264.7 cell experiments showed that SP800201 could significantly improve the proliferation and phagocytosis of macrophages, and promote the release of NO, TNF-α, IL-1β, and IL-6. Results of vivo experiments in immunocompromised zebrafish showed that SP800201 could also significantly increase the density of immune cells, the number of macrophages, and reduce NO, TNF-α, IL-1β, and IL-6. The above results showed that the Saposhnikoviae Radix polysaccharide has certain immunomodulatory activity.

Abstract
In this study, the intracellular signaling pathways involved in macrophage activation through the RG-I-type polysaccharide (REP-I) purified from radish leaves were elucidated. The gene expression and secretion of immune-related factors such as interleukin (IL)-6, tumor necrosis factor (TNF)-α, and nitrogen oxide (NO) from macrophages were enhanced by the addition of REP-I. Moreover, immunoblotting and immunocytochemistry analyses indicated that REP-I dose-dependently phosphorylated the mitogen-activated protein kinase (MAPK) and nuclear factor-κB (NF-κB) pathways. An investigation using different inhibitors revealed that the effect of REP-I on NO secretion was mostly promoted by c-Jun N-terminal kinase (JNK) and NF-κB. Furthermore, the secretion of IL-6 was mostly induced via extracellular-signal-regulated kinase (ERK), JNK, and NF-κB. TNF-α secretion was mostly induced via NF-κB. In contrast, an investigation using anti-pattern recognition receptor (PRR) antibodies revealed that the effect of REP-I on the secretion of NO was mostly related with dectin-1, scavenger receptor (SR), toll-like receptor (TLR)2, TLR4, CD14, and CD11b. Furthermore, the secretion of IL-6 was mostly involved with SR, and the secretion of TNF-α was mostly relevance to TLR2. In conclusion, it is affirmed that immunostimulatory activation of macrophage of REP-I purified from radish leaves was deeply associated with several PRR and phosphorylating MAPK and NF-κB.
