Our previous paper reported the structure of ginseng pectic polysaccharides related to the cell migration inhibitory effects, but the underlying mechanisms are poorly understood. In this manuscript, rhamnogalacturonan I (RGI)-rich pectins prepared from ginseng pectin were investigated for their effect on cell migration. The results indicated that the combination of homogalacturonan (HG) and RGI-rich pectins exerted stronger effects than either HG- or RGI-rich pectin alone. Further studies revealed that the effects of HG- and RGI-rich pectins were dependent on pretreatment, which caused alterations in cell morphologies such as cell size and shape, focal adhesion, and the organization of actin filaments, suggesting that HG and RGI pectins exert synergistic effects on cell migration, likely through different ways...

This study was carried out to investigate the efficiency of red ginseng nanopowder in preventing collagen-induced arthritis (CIA) in mice. The mice were divided into five groups: normal group (no immunisation), control (CIA), powdered red ginseng (PRG), nanopowdered red ginseng (NRG) and methotrexate (MTX). Administering MTX, PRG and NRG to arthritic mice significantly decreased spleen indexes, clinical and histological scores compared to control group. Serum analysis of NRG and MTX groups showed a reduction in the cytokines such as the levels of tumour necrosis factor alpha (TNF-α), interleukin 6 (IL-6) and interleukin 1β (IL-1β) in comparison to PRG group...

Pectins isolated from Panax ginseng C.A. Meyer are potential therapeutic agents for the treatment of diabetes mellitus, a global health challenge. Soil-to-bench procedures of ginseng pectin preparation significantly affect the polysaccharide structures. Various forms of ginseng pectins rich in homogalacturonan, rhamnogalacturonan-I, rhamnogalacturonan-II, and arabinogalactan have demonstrated independent or collaborative effects on hyperglycemia, oxidative stress, immunological dysfunction, and neoplasms. Monosaccharide compositions, peptide contents, degrees of esterification and methylation, and inter- and intramolecular linkages all influence pectin bioactivity...
