Abstract Panax ginseng C. A. Mey. is an important plant species used in traditional Chinese medicine, whose primary active ingredient is a ginsenoside. Ginsenoside biosynthesis is not only regulated by transcription factors but also controlled by a variety of structural genes. Nonetheless, the molecular mechanism underlying ginsenoside biosynthesis has always been a topic in the discussion of ginseng secondary metabolites. Squalene epoxidase (SQE) is a key enzyme in the mevalonic acid pathway, which affects the biosynthesis of secondary metabolites such as terpenoid. Using ginseng transcriptome, expression, and ginsenoside content databases, this study employed bioinformatic methods to systematically analyze the genes encoding… More >

Abstract Background: A preliminary miRNA screening showed that expression levels of rno-miRNA-27a-3p were significantly increased in the serum and brain tissues of rats undergoing cerebral ischemia. In recent years, there is evidence of the protective capacity of the saponins extracted from panax ginseng and its primary active ingredient ginsenosideRg1oncerebral ischemic injury. Methods: Fetal rat neurons (FRNs) were cultured in glucose-and-serum-free medium and exposed to hypoxia to establish a cerebral ischemia model in vitro (oxygen and glucose deprivation model, OGD). Antioxidant indexes (CAT, SOD), inflammatory markers (MPO, TNF-α and IL-6), and the expression of apoptosis and proliferation associated proteins (NF kB-p65, Caspase… More >

Abstract Ginsenoside Rb3 (G-Rb3) is one of the primary active compounds isolated from Panax ginseng Meyer, which belongs to protopanaxadiol ginsenosides (PPD). Based on the structure-activity relationship (SAR) of ginsenosides, the pentose structure of G-Rb3 limited itself to possess more pharmacological activity to a certain extent. However, pharmacokinetics show that G-Rb3 is processed through deglycosylation in the intestinal tract and converted into more active rare saponins, such as Compound K, F2, etc. A series of studies focused on neuroprotection and the cardiovascular system demonstrating its therapeutic potentials, which was achieved by diminishing oxidative stress and apoptosis. Therefore, more systematic and in-depth… More >

Abstract Heat stress (HS) reaction can lead to serious physiological dysfunction associated with cardiovascular and various organ diseases. Ginsenoside Rg3 (G-Rg3) is a representative component of ginseng rare saponin and can protect against multiple organs, also used as functional food to adjust the balance of the human body, but the therapeutic effect and molecular mechanism of G-Rg3 on male diseases under HS are underexplored. The aim of the present study, G-Rg3 was prepared through the efficient conversion of ginsenoside Rd and investigate the contribution of G-Rg3 to testicular injury induced exposure to HS. All mice were divided into four groups as… More >
