Puerarin, a bioactive isoflavone glucoside extracted from radix Puerariae, has been proven to possess many biological activities. However, the role of puerarin in protecting bovine Sertoli cells (bSCs) under heat stress conditions remains to be clarified. The present study aimed to explore the possible protective mechanism of puerarin for primary cultured bSCs subjected to heat stress. Bovine Sertoli cells were treated with 15 μM of puerarin before they were exposed to 42 °C for 1 hour. The dose of puerarin (15 μM) was determined on the basis of cell viability...

Previous study has demonstrated that puerarin (PU) exerts nephroprotective effect against Pb-induced cytotoxicity in primary rat proximal tubular (rPT) cells. Autophagy can protect cells from various cytotoxic stimuli, but its role in the process of PU against Pb-induced nephrotoxicity is still unknown. This study aims to investigate whether PU can alleviate Pb-induced renal damage by recovering autophagy. Data showed that Pb inhibited the autophagic flux, as evidenced by the accumulation of LC3-II and p62 as well as the confocal microscopy analysis of GFP-LC3 puncta and punctate spots of monodansylcadaverine staining, whereas coadministration of PU could restore Pb-induced autophagy inhibition...

Puerarin, a known isoflavone, is commonly found as a Chinese herb medicine. It is widely used in China to treat cardiac diseases such as angina, cardiac infarction and arrhythmia. However, its cardioprotective mechanism remains unclear. In this study, puerarin significantly prolonged ventricular action potential duration (APD) with a dosage dependent manner in the micromolar range on isolated rat ventricular myocytes. However, submicromolar puerarin had no effect on resting membrane potential (RMP), action potential amplitude (APA) and maximal velocity of depolarization (Vmax) of action potential...

ETHNOPHARMACOLOGICAL RELEVANCE: Reactive oxygen species (ROS) mediate vascular cell dysfunction and lead to atherosclerosis and other chronic cardiovascular diseases. The root of Pueraria lobata (Willd.) Ohwi, also known as kudzu or Gegen (Chinese name), is one of the most important herbs in traditional Chinese medicine and has been widely used in the treatment of cardiovascular diseases, diabetes, osteonecrosis and neurodegradation diseases. In this study, an ethanol extract from kudzu root was prepared and the in vitro protective effect of the kudzu root extract (KUD) on human umbilical vein endothelial cells (HUVECs) was investigated...

Puerarin (PU) is a potent free radical scavenger with a protective effect in nephrotoxin-mediated oxidative damage. Here, we show a novel molecular mechanism by which PU exerts its anti-apoptotic effects in cadmium (Cd)-exposed primary rat proximal tubular (rPT) cells. Morphological assessment and flow cytometric analysis revealed that PU significantly decreased Cd-induced apoptotic cell death of rPT cells. Administration of PU protected cells against Cd-induced depletion of mitochondrial membrane potential (ΔΨm) and lipid peroxidation...

AIMS: Puerarin is a phytoestrogen that shows osteogenic effects. Meanwhile, zinc stimulates bone formation and inhibits bone resorption. The study aims to investigate the effects of coadministration of puerarin (low dose) and zinc on bone formation in ovariectomized rats. MATERIALS AND METHODS: Co-administration or use alone of puerarin (low dose) and/or zinc were gavaged in OVX rats. The estrogen-like effects were detected by the uterus weight, the histologic observation and the IGF-1 protein expression...

In methodology, The LF rats were prepared through intragastrically giving CCl4 twice each week (2ml/kg, v/w) for 8weeks, and dosed puerarin (20, 40mg/kg) were given three times each week via intraperitoneal injection. After being conducted with oral glucose tolerance test (OGTT), the blood samples of rat were harvested for biochemical tests, as well as the liver and pancreas were isolated for histological examination and biochemical assays...

Aging, a puzzling question in the medical field, is a multifactorial process that results in a progressive functional decline at cellular, tissue, and organismal levels. Although it is impossible to prevent aging, slowing down the pace of aging is entirely possible to achieve. Traditional Chinese medicine (TCM) is characterized by the nourishing of life, its role in anti-aging is getting more and more attention. This article summarizes the natural products from TCM that are reported to have anti-aging effects in the past two decades...

AIMS: Previous research has revealed that puerarin, the major phytoestrogen in tuberous roots of Pueraria lobota and Pueraria mirifica, acts as a selective estrogen receptor modulator that displays predominantly estrogenic potential for health benefit. However, little is known about the estrogenic potency of puerarin in pituitary, especially in the rat model of postmenopausal females. MAIN METHODS: Plasma prolactin and growth hormone levels as well as mRNA expression levels of pituitary estrogen-regulated genes, such as estrogen receptor (ER) subtypes alpha (ERα) and beta (ERβ), truncated ER product-1 (TERP-1) and -2 (TERP-2) and gonadotropin alpha subunit, were examined using radioimmunoassay and TaqMan® real-time PCR, respectively...

This study aimed to investigate the protective effect of genistein or puerarin on chronic alcohol-induced liver injury in vivo and to explore the underlying mechanisms of hepatoprotective effects. Mice were administered genistein or puerarin (0.3 mmol kg(-1) body weight) and gastrically infused with 50% alcohol once per day for 5 weeks. Levels of serum transaminases, serum and hepatic lipids, hepatic antioxidant capacities, inflammation, apoptosis, and histopathological sections were analyzed. Results showed that genistein and puerarin exhibited similar effects in ameliorating alcohol-induced liver injury...

Puerarin, a type of isoflavone, was shown to have multiple protective effects on myocardial injury. The objective of this study was to investigate the role of puerarin in the progression of lipotoxic cardiomyopathy. Primary cardiomyocytes were isolated from FATP1 transgenic (Tg) mice with lipotoxic cardiomyopathy, and various concentrations of puerarin were used to incubate with the cardiomyocytes. Our results showed low dose puerarin (≤ 20 μM) treatment increased the cell viability and decreased the accumulation of free fatty acid (FFA)...
