UVB-exposed keratinocytes secrete various paracrine factors. Among these factors, basic fibroblast growth factor (bFGF) stimulates the proliferation of melanocytes. Ginsenosides, the major active compounds of ginseng, are known to have broad pharmacological effects. In this study, we examined the anti-proliferative effects of ginsenosides on bFGF-induced melanocyte proliferation.

Heat processed ginseng, Sun ginseng (SG), has been reported to have improved therapeutic properties compared to raw forms, such as increased efficiencies of anti-diabetic, anti-inflammatory, and anti-hyperglycemic effects. The aim of the present study was to investigate the anti-obesity effects of SG through the suppression of cell differentiation and proliferation of mouse 3T3-L1 preadipocyte cells and the lipid accumulation in Caenorhabditis elegans (C. elegans).

KG-135, a standardized formulation enriched with Rk1, Rg3, Rg5, had been shown to inhibit various types of cancer cells but the underlying mechanisms are not fully understood. We explore its effects in A549 human lung cancer cells to investigate the induction of FOXO3a and autophagy.

Korean Red Ginseng (KRG) is a traditional herbal medicine made by steaming and drying fresh ginseng. It strengthens the endocrine and immune systems to ameliorate various inflammatory responses. The cyclooxygenase-2 (COX-2)/prostaglandin E2 pathway has important implications for inflammation responses and tumorigenesis. Peroxisome proliferator-activated receptor gamma (PPARγ) is a transcription factor that regulates not only adipogenesis and lipid homeostasis but also angiogenesis and inflammatory responses.

Three greenhouse experiments with American ginseng seedlings growing under light levels from 4.8 to 68% showed a quadratic response for root dry weight giving an optimal root dry weight of 239 mg (range 160 to 415) at an optimal light level of 35.6% (range 30.6 to 43.2).

Ginsenosides Rh2 (GRh2) are the main bioactive components in American ginseng, a commonly used herb, and its anti-tumor activity had been studied in previous studies. PDZ-binding kinase/T-LAK cell-originated protein kinase (PBK/TOPK), a serine/threonine protein kinase, is highly expressed in HCT116 colorectal cancer cells.

Nephrotoxicity is the major side effect in cisplatin chemotherapy. Previously, we reported that the ginsenoside Rk3 and Rh4 reduced cisplatin toxicity on porcine renal proximal epithelial tubular cells (LLC-PK1). Here, we aimed to evaluate the protective effect of ginsenoside Rk3 and Rh4 on kidney function and elucidate their antioxidant effect using in vitro and in vivo models of cisplatin-induced acute renal failure (AKI).

There is limited understanding of the interaction between ginsenoside Re and B-complex vitamins.

Chong Myung-Tang (CMT) extract is being widely used in Korea as a traditional herbal tonic for increasing memory capacity in high school students and also for numerous body ailments since centuries. The use of CMT as to improve the learning capacity has been attributed to various plant constituents majorly black ginseng present in it. Therefore, in this study, we have first investigated whether black ginseng enriched CMT extracts affected spatial learning using Morris water maze test. Their molecular mechanism of action underlying improvement of learning and memory was examined in vitro.

The natural ratios of C, N, and S stable isotopes can be varied to some specific living creatures owing to various isotopic fractionation processes in nature. Therefore, the analysis of C, N, and S stable isotope ratios in ginseng can provide a feasible method for determining ginseng authenticity depending on the cultivation land and type of fertilizer.
