BACKGROUND
Diosgenin, a steroidal saponin from plants, exhibits many biological potentials. Herein, the cardioprotective role of diosgenin is studied.
METHODS
The effect of diosgenin, isolated from Dioscorea bulbifera, was studied on hypoxia-reoxygenation (HR) in H9c2 cardiomyoblast cells. The
OBJECTIVE
To explore the effects of Panax Quinquefolium Saponin (PQS) on phosphatidylinositol 3-kinase/serine threonine kinase (PI3K/Akt) pathway of neonatal rat myocardial cells subjected to hypoxia.
METHODS
Neonatal rat myocardial cells were cultured in vitro. After the myocardial cell injury was
The saponin monomer 13 of dwarf lilyturf tuber (DT-13), one of the saponin monomers of dwarf lilyturf tuber, has been found to have potent cardioprotective effects. In order to investigate the effects of DT-13 on L-type calcium currents (I(Ca,L)), exploring the mechanisms of DT-13's cardioprotective
Gynostemma pentaphyllum possesses the neuroprotective bioactivity. However, the effect of gypenosides on the hypoxia-induced neural damage remains obscure. In this study, Gyp, the active fraction extracted from G. pentaphyllum, and its bioactive compounds as well as the underlying molecular
Four steroidal saponins were isolated from the anti-anoxic fraction of the 60% EtOH extract of Selaginella uncinata, including two new compounds, (3β, 7β, 12β, 25R)-spirost-5-ene-3, 7, 12-triol-3-O-α-L-rhamnopyranosyl-(1→2)-O-[α-L-rhamnopyranosyl-(1→4)]-O-β-D-glucopyranoside (1), (2α, 3β, 12β,
To investigate the effects and underlying mechanisms of Panax quinquefolium saponin (PQS) on energy deficiency in hypoxia-reperfusion (H/R) induced cardiomyocytes.The H/R injury involved hypoxia for 3 h and then reperfusion for 2 h. Cardiomyocytes recruited Adhesion and migration of tumor cells are crucial steps in tumor invasion and metastasis. In the present study, we investigated the effects of saponin monomer 13 of dwarf lilyturf tuber (DT-13) on metastasis of human breast cancer cells (MDA-MB-435) during hypoxia. The effects and molecular
The effects of ginseng total saponins (GTS) on hypoxic damage of primary cultures of astrocytes were studied. Hypoxia was created by placing cultures in an air tight chamber that was flushed with 95% N(2)/5% CO(2) for 15 min before being sealed. Cultures showed evidence of significant cell injury
Hypoxia frequently occurs under several different cellular circumstances. Excess reactive oxygen species that are induced by hypoxia may result in cell injury and dysfunction. Recently, garlic has been found to possess some biological and pharmacological activities. The present study examined the
OBJECTIVE
To explore the mechanism of protective effects of salvianolic acids and Panax notoginseng saponins and their combination on cardiomyocytes suffered with hypoxia-reoxygenation (HR) injury.
METHODS
HR-injured H9c2 cell was employed as cellular model to evaluate cardioprotective effects of
The present study monitored the effect of 2, 10, and 50 mg/L of Panax notoginseng saponin exposure following hypoxia-reoxygenation injury in fetal rat cortical neurons. Results showed that varying doses of Panax notoginseng saponin significantly enhanced the cell viability of neurons, reduced
The saponin monomer of dwarf lilyturf tuber, DT-13, exhibits anticancer activity by reducing human breast cancer cell adhesion and migration under hypoxia. To further investigate the anticancer activity of DT-13, we investigated whether DT-13 exhibits anti-angiogenic activity. DT-13 showed no effect
Two new flavonoid-triterpene saponin meroterpenoids, clinoposides G (1) and H (2) were isolated from the aerial parts of Clinopodium chinense (Benth.) O. Kuntze. Their structures were elucidated through spectroscopic and electronic circular dichroism (ECD) analyses. Compounds 1 and 2 were evaluated
BACKGROUND
Our ongoing research has revealed that total saponins extracted from the medicinal herb Radix Astragali (AST) exhibits significant growth-inhibitory and proapoptotic effects in human cancer cells. In the present study, the potential of AST in controlling angiogenesis was further
OBJECTIVE
To study the inhibitory effects of Panax Notoginseng Saponins(PNS) on apoptosis induced by hypoxia/hypoglycemia and reoxygenation in cultured rat hippocampal neurons.
METHODS
Apoptosis were measured by flow cytometry, intracellular free calcium concentration([Ca2+]i) was measured with
