Diosgenin is a major compound of Dioscoreaceae plants such as yam, which is used as a drug in Traditional Chinese Medicine, and a common vegetable worldwide. The anticancer effect of diosgenin has been reported in various tumor cells, including leukemia, gastric, colorectal, and breast cancer. However, the activity of diosgenin on hepatocellular carcinoma (HCC) and the underlying mechanism have...

Diosgenin exists in some food supplements and herbal medicines and lowers plasma cholesterol by increasing fecal cholesterol excretion. It is believed that diosgenin promotes fecal cholesterol excretion by stimulating biliary cholesterol secretion and decreasing intestinal cholesterol absorption. Niemann-Pick C1-like 1 (NPC1L1) was recently identified as an essential protein for intestinal chol...

The aim of this study was to investigate the effects and the mechanism of diosgenin, a famous plant-derived steroidal sapogenin, on memory deficits in Alzheimer's disease (AD) model mice. Diosgenin-treated 5XFAD mice exhibited significantly improved performance of object recognition memory. Diosgenin treatment significantly reduced amyloid plaques and neurofibrillary tangles in the cerebral cor...

BACKGROUND Diosgenin, a steroidal saponin obtained from fenugreek (Trigonella foenum graecum), was found to exert anti-carcinogenic properties, such as inhibiting proliferation and inducing apoptosis in a variety of tumor cells. However, the effect of diosgenin on cancer metastasis remains unclear. The aim of the study is to examine the effect of diosgenin on migration and invasion in human pro...

We previously reported that diosgenin, a plant-derived steroidal sapogenin, improved memory and reduced axonal degeneration in an Alzheimer's disease mouse model. Diosgenin directly activated the membrane-associated rapid response steroid-binding receptor (1,25D₃-MARRS) in neurons. However, 1,25D₃-MARRS-mediated diosgenin signaling was only shown in vitro in the previous study. Here, we aimed t...

Objective(s) Several studies have reported improved response of exercised hearts to myocardial infarction (MI). This study was aimed to evaluate the preventive role of treadmill exercise and diosgenin on cardiac marker enzymes, thiobarbituric acid reactive substances (TBARS), total antioxidant status (TAS), lipids, and electrocardiographic (ECG) patterns in isoproterenol (ISO)-induced myocardia...

This study investigated the in vivo effect of Diosgenin, isolated from Asparagus officinalis, on the total quantity of Cytochrome P450, the activity of some enzymes Ethylmorphine N-demethylase (marker for CYP3A) and Aniline Hydroxylase (marker for CYP2E1), the quantity of malondialdehyde and reduced glutathione compared to Phenobarbital in rats. Diosgenin and Phenobarbital, administered alone, ...

The aim of this study was to investigate the activity of diosgenin against Naegleria fowleri trophozoites at the cellular and molecular levels. Diosgenin (100 μg/ml; 241.2 μM) had a 100% inhibitory effect on N. fowleri trophozoites (5 x 10(5) cell/ml). Scanning electron micrograph revealed diosgenin decreased the number of sucker-like apparatuses and food cup formation among N. fowleri trophozo...

The purpose of this study was to determine whether diosgenin suppresses cholesterol absorption in rats, and to examine relevant changes in cholesterol and bile acid metabolism. Diosgenin fed with the diet for 1 week inhibited cholesterol absorption as determined by the serum isotope ratio technique, as well as by measuring in the feces the amount of unabsorbed radioactivity from orally administ...

OBJECTIVE To seek efficient aldose reductase inhibitors (ARIs) with excellent in vitro and in vivo biological activities against rat galactosemic cataract. METHODS The method was firstly optimized to screen strong ARIs from nonoriented synthetic compounds and natural extracts. Then, diosgenin was assessed on osmotic expansion of primarily cultured lens epithelial cells (LECs) induced by galac...
