-Prenyltransferase interacts with a Nogo-B receptor homolog for dolichol biosynthesis in Meyer
Prenyltransferases catalyze the sequential addition of IPP units to allylic prenyl diphosphate acceptors and are classified as either trans-prenyltransferases (TPTs) or cis-prenyltransferases (CPTs). The functions of CPTs have been relatively well characterized in bacteria, yeast, and mammals compared to that of in plants. The characterization of CPTs also has been less studied than TPTs. In this present study, molecular cloning and functional characterization of a CPT from a medicinal plant, Panax ginseng Mayer are addressed.
20S-Protopanaxadiol, an aglycosylated ginsenoside metabolite, induces hepatic stellate cell apoptosis through LKB1-AMPK activation
Previously, we reported Korean Red Ginseng inhibited liver fibrosis in mice and reduced the expressions of fibrogenic genes in hepatic stellate cells (HSCs). The present study was undertaken to identify the major ginsenoside responsible for reducing numbers of HSCs and the underlying mechanism involved.
The effects of ginseng on stress-related depression, anxiety, and the hypothalamic-pituitary-adrenal axis
Ginseng effectively regulates the immune response and the hormonal changes due to stress, thus maintaining homeostasis. In addition to suppressing the occurrence of psychological diseases such as anxiety and depression, ginseng also prevents stress-associated physiological diseases. Recent findings have revealed that ginseng is involved in adjusting the hypothalamic-pituitary-adrenal axis and controlling hormones, thus producing beneficial effects on the heart and brain, and in cases of bone diseases, as well as alleviating erectile dysfunction.
Protective effect of ginsenoside Rh3 against anticancer drug-induced apoptosis in LLC-PK1 kidney cells
Ginsenosides are active components of Panax ginseng that exert various health benefits including kidney protection effect. The medicinal activity of ginsenosides can be enhanced by modulating their stereospecificity by heat processing. Ginsenosides Rk2 and Rh3 represent positional isomers of the double bond at C-20(21) or C-20(22).
Korean Red Ginseng exhibits no significant adverse effect on disease activity in patients with rheumatoid arthritis: A randomized, double-blind, crossover study
Panax ginseng is a well-known immune modulator, and there is concern that its immune-enhancing effects may negatively affect patients with rheumatoid arthritis (RA) by worsening symptoms or increasing the risk of adverse effects from other drugs. In this randomized, crossover clinical trial, we evaluated the impact of Korean Red Ginseng (KRG) on disease activity and safety in RA patients.
The molecular signaling of ginsenosides Rb1, Rg1, Rg3 and their mode of actions
Ginseng has gained its popularity as an adaptogen since ancient days due to their triterpenoid saponins, known as ginsenosides. These triterpenoid saponins are unique and classified as protopanaxatriol and protopanaxadiol saponins based on their glycosylation patterns. It shows many protective roles in humans and is of intense research to understand their efficacy at the molecular aspect in various disorders. Ginsenoside Rb1 and Rg1 are the most abundant ginsenosides present in ginseng roots, and they confer the pharmacological property of it while ginsenoside Rg3 is abundantly present in the Korean Red Ginseng (KRG) preparation, which is highly known for its anti-cancer effect.
Subacute oral toxicity and bacterial mutagenicity study of Korean red ginseng oil
Red ginseng oil (RGO) is produced by supercritical CO2 extraction of secondary products derived from Korean red ginseng extract. As the use of RGO has increased, product safety concerns have become more important.
Qualitative and quantitative analysis of the saponins in leaves using ultra performance liquid chromatography coupled with time-of-flight tandem mass spectrometry and high performance liquid chromatography coupled with UV detector
Panax notoginseng leaves (PNL) exhibit the extensive activities, but few analytical methods were established to exclusively determine the dammarane triterpene saponins in PNL.
The effect of red ginseng and ginseng leaves on the substance and energy metabolism in hypothyroidism rats
Recent studies revealed that the property of traditional Chinese medicine is mostly associated with the substance and energy metabolism. Our study was to compare the effect of red ginseng (warm property) and ginseng leaves (cold property) on the substance and energy metabolism in hypothyroidism rats.
