Proanthocyanidins: novel treatment for psoriasis that reduces oxidative stress and modulates Th17 and Treg cells

Redox Report, 2018
Psoriasis is a common, chronic, inflammatory skin disease that affects 2%–4% of the global population. Recent studies have shown that increased oxidative stress (OS) and T-cell abnormalities are central to the pathogenesis of this disease.

Antioxidant and antiviral properties of Pseudopiptadenia contorta (Leguminosae) and of quebracho (Schinopsis sp.) extracts

Química Nova, 2005
Proanthocyanidins from P. contorta leaves and from a commercial quebracho extract were isolated and characterized. Flavonoids, catechins and gallic acid were also identified in the extracts of P. contorta.

WRKY Transcription Factors: Integral Regulators of Defence Responses to Biotic Stress in Crops

Plant Biotechnology Journal, EarlyView.
ABSTRACT Crops are continually challenged by biotic stresses, including fungal, bacterial and viral pathogens and insect pests, which cause substantial yield and quality losses worldwide. WRKY transcription factors constitute a plant‐specific and functionally diverse family that is central to immune regulation.

Multi‐Omics Insights Into Anthraquinone Biosynthesis in Rheum tanguticum

Plant Biotechnology Journal, EarlyView.
ABSTRACT Rheum tanguticum is renowned for its medicinal properties, including purgative, anti‐inflammatory and hepatoprotective effects, primarily attributed to anthraquinones (AQs). However, the molecular mechanisms of AQs biosynthesis have largely been hindered by insufficient genomic resources and functional genomics investigations.

Encapsulated Proanthocyanidins as Novel Ingredients

Chemical Engineering Transactions, 2017
Proanthocyanidins (OPC) are polyphenolic compounds, derivatives of flavan-3-ol flavonoids. They are abundant in grape seeds and skins, and contribute to most of the polyphenols in red wine. Proanthocyanidins from grape seed have been reported to show various health as well as technological properties.

Natural Variations in the Activity of Hydroxycinnamoyl Transferases Promote Accumulation of Metabolites Conferring Rice Resistance

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant‐derived secondary metabolites act as regulators of in planta defence. Plant phenylpropanoid metabolic compounds, including final metabolites such as lignin and flavonoids, and a few intermediate metabolites play critical roles in defence.

Cross‐Species Reprogramming of Developmental Plasticity and Metabolic Rewiring via Banana‐Derived WUS2 Developmental Regulator

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant regeneration is governed by intrinsic gene regulation and phytohormonal cues. WUSCHEL (WUS) gene promotes regeneration, but its broader functional role remains unexplored. Here, we demonstrate that the constitutive and inducible expression of banana‐derived WUS2 (GN‐WUS2) enhances regeneration in Nicotiana tabacum (tobacco) and Musa ...

The effects of a (poly)phenol‐rich food intervention on markers of exercise‐induced inflammation and oxidative stress: A randomised controlled trial

Experimental Physiology, EarlyView.
Abstract This study examined whether consuming a (poly)phenol‐rich food before strenuous muscle‐damaging exercise can modify post‐exercise markers of inflammation and oxidative stress. Using a double‐blinded, randomised, placebo‐controlled, between‐subjects design, 26 recreationally active males (n = 15) and females (n = 11) consumed higher‐(poly ...
