An isolate of the fungus Puccinia striiformis, causing yellow (stripe) rust on cereals and grasses, was selfed on the alternate (sexual) host, Berberis vulgaris. This enabled us to investigate genetic variability of progeny isolates within and among aecia. Nine aecial clusters each consisting of an aecium (single aecial cup) and nine clusters containing multiple aecial cups were selected from 18 B. vulgaris leaves. Aeciospores from each cluster were inoculated on susceptible wheat seedlings and 64 progeny isolates were recovered...

Natural products or nutraceuticals promote anti-aging, anti-cancer and other health-enhancing effects. A key target of the effects of natural products may be the regulation of the PI3K/PTEN/Akt/mTORC1/GSK-3 pathway. This review will focus on the effects of curcumin (CUR), berberine (BBR) and resveratrol (RES), on the PI3K/PTEN/Akt/mTORC1/GSK-3 pathway, with a special focus on GSK-3. These natural products may regulate the pathway by multiple mechanisms including: reactive oxygen species (ROS), cytokine receptors, mirco-RNAs (miRs) and many others...

Berberis vulgaris (Bv) is well known worldwide for its healing properties. However, limited information is available concerning its mechanism of action and the increased hepatoprotective activity of formulated extracts. This study evaluated the protective effect of Bv bark extract against CCl4-induced cytotoxicity in Huh7 cells, as well whether β-cyclodextrin complexation of the extract resulted in increased hepatoprotective effects. Huh7 cells were incubated for 48 h with 5, 7.5 and 10 µg/ml of unformulated or formulated Bv extract alone and in co-treatment with CCl4...

BACKGROUND AND AIMS: Oxidized LDL (oxLDL) or pro-inflammatory stimuli lead to increased oxidative stress linked to endothelial dysfunction and atherosclerosis. The oxLDL receptor-1 (LOX1) is elevated within atheromas and cholesterol-lowering statins inhibit LOX1 expression. Berberine (BBR), an alkaloid extracted from plants of gender Berberis, has lipid-lowering and anti-inflammatory activity. However, its role in regulating LOX1-mediated signaling is still unknown. The aim of this study was to investigate the effect of BBR on oxLDL- and TNFα-induced endothelial dysfunction in human umbilical vein endothelial cells (HUVECs) and to compare it with that of lovastatin (LOVA)...

Stripe rust (Yellow rust) caused by Puccinia striiformis f. sp. tritici (Pst) is a major disease of wheat worldwide. The use of resistant cultivars to control Pst has been very effective, low-cost, and ecologically sound. However, virulence patterns of Pst can quickly change, which may render resistant cultivars susceptible. The discovery of infection of Berberis spp. by basidiospores of Pst in 2010 raised important concerns about the evolution of new virulent races of the pathogen. Little is known about the infection process of Berberis spp...

Forecasting ecological responses to climate change, invasion, and their interaction must rely on understanding underlying mechanisms. However, such forecasts require extrapolation into new locations and environments. We linked demography and environment using experimental biogeography to forecast invasive and native species' potential ranges under present and future climate in New England, United States to overcome issues of extrapolation in novel environments. We studied two potentially nonequilibrium invasive plants' distributions, Alliaria petiolata (garlic mustard) and Berberis thunbergii (Japanese barberry), each paired with their native ecological analogs to better understand demographic drivers of invasions...

Status epilepticus (SE) is a life-threatening neurologic condition, instigating epileptogenesis to transform normal brain to an epileptic condition. SE is followed by spontaneous recurrent seizures (SRS) and final development of temporal lobe epilepsy (TLE) that is resistant to treatment. Neuroprotective strategies are increasingly put forward as a promising therapy to prevent and/or manage epileptic conditions. In this study, we investigated whether berberis alkaloid, i.e. berberine (BBR), could ameliorate intrahippocampal kainate-induced SE and its consequent epileptogenic process and to explore some underlying mechanisms...

BACKGROUND: Berberis aristata, because of its berberine content, and Monascus purpureus fermented rice, because of the presence of monacolins (naturally derived statins), are widely investigated food-grade ingredients used to formulate cholesterol-lowering supplements. Although they are extensively used, berberine is poorly absorbed and monacolins are poorly chemically characterized, not standardized, and possibly contaminated with toxic compounds. Silymarin is reported to enhance berberine absorption, while Monakopure™-K20 (MK-20) is a highly standardized red yeast rice containing monacolins K and KA in the ratio of 1:1 but not secondary monacolins, dehydromonacolins, or citrinin...
