Inhibitory Mechanism of Ginsenoside Rh3 on GM-CSF Expression in UVB-irradiated Murine SP-1 Keratinocytes
ConclusionIn summary, we found that ginsenoside Rh3 impeded UVB-induced GM-CSF production through repression of PKCδ and ERK phosphorylation in SP-1 keratinocytes. (Source: Journal of Ginseng Research)

Ginsenoside Rf inhibits cyclooxygenase-2 induction via peroxisome proliferator–activated receptor gamma in A549 cells
ConclusionsOur results demonstrate that ginsenoside Rf inhibits hypoxia induced-COX-2 expression and cellular migration, which are dependent on PPARγ activation. These results suggest that ginsenoside Rf has an antiinflammatory effect under hypoxic conditions. Moreover, docking analysis of ginsenoside Rf into the active site of PPARγ suggests that the compound binds to PPARγ in a position similar to that of known agonists.

Korean red ginseng attenuates type 2 diabetic cardiovascular dysfunction in OLETF rats
We examined the protective potential of KRG against type 2 diabetic illnesses. The results exhibited that KRG showed significant antihyperglycemic and antioxidative effects in KRG-treated OLETF rats. And, our results proposed the amelioration of cardiac function through normalized ejection fraction, fractional shortening and vascular reactivity. Furthermore, histopathological abnormalities in the OLETF rats were prevented by KRG treatment. (Source: Journal of Ginseng Research)

Ginsenoside Rb2 suppresses the glutamate-mediated oxidative stress and neuronal cell death in HT22 cells
ConclusionOur results suggest that Rb2 possesses neuroprotective properties that suppress glutamate-induced neurotoxicity. The molecular mechanism of Rb2 is by suppressing the MAPKs activity and AIF translocation. (Source: Journal of Ginseng Research)

New dammarane-type triterpenoid saponins from Panax notoginseng saponins
ConclusionThree new triterpenoid saponins (1-3) together with twenty-five known rare saponins (4-28) were isolated from PNS, except for the five main compounds (notoginsenoside R1 and ginsenoside Rg1, Rd, Re and Rb1). In addition, the HPLC fingerprint of PNS was established, and the peaks of the isolated compounds were marked. The study of chemical constituents and fingerprint were useful for the quality control of PNS. The study on antitumor activities showed that new compound 2 exhibited significant inhibitory activity against the tested cell lines. (Source: Journal of Ginseng Research)

Ginseng for an eye: Effects of ginseng on ocular diseases
Publication date: Available online 30 November 2018Source: Journal of Ginseng ResearchAuthor(s): Jisu Kim, Su-Young Han, Hyeyoung MinAbstractThe sense of vision is the primary means by which we gather information from our surroundings, and vision loss, therefore, severely compromises the life of the affected individuals, their families, and society. Loss of vision becomes more frequent with age, and diabetic retinopathy, age-related macular degeneration, cataracts, and glaucoma are the major causes of vision impairment. To find active pharmacological compounds that might prevent or ameliorate the vision-threatening eye dis...

Transcriptome analyses of the ginseng root rot pathogens Cylindrocarpon destructans and Fusarium solani to identify radicicol resistance mechanisms
Publication date: Available online 23 November 2018Source: Journal of Ginseng ResearchAuthor(s): Taiying Li, Jin-Hyun Kim, Boknam Jung, Sungyeon Ji, Mun Won Seo, You Kyoung Han, Sung Woo Lee, Yeoung Seuk Bae, Hong-Gyu Choi, Seung-Ho Lee, Jungkwan LeeAbstractBackgroundThe ascomycete fungi Cylindrocarpon destructans (Cd) and Fusarium solani (Fs) cause ginseng root rot and significantly reduce the quality and yield of ginseng. Cd produces the secondary metabolite radicicol, which targets the molecular chaperone Hsp90. Fs is resistant to radicicol, whereas other fungal genera associated with ginseng disease are sensitive to it...
