Xanthohumol in Treating Nephropathy and Autoimmune Kidney Diseases: Clinical Data
Dr. Andrzej Jaroszyński from Jan Kochanowski University, Poland will be joining the 17th World Congress on Polyphenols Applications 2024 this September in Milan.
Presentation Topic: Xanthohumol in Treating Nephropathy and Autoimmune Kidney Diseases: Clinical Data.
Presentation Summary:
- IgAN is the most common primary glomerulonephritis worldwide, characterized by immune system abnormalities, inflammation, oxidative stress, and fibrosis in its pathogenesis.
- Xanthohumol (XN) is known for its ability to inhibit proinflammatory pathways and to modulate various cell signaling pathways.
- XN also has anti-fibrotic and immunomodulatory effects, as well as antioxidant properties, reducing oxidative stress.
- The study aimed to assess XN's potential in treating IgAN, specifically in patients refractory to conventional treatments and with a poor prognosis.
- After 3 months of XN supplementation, two patients achieved a significant reduction in proteinuria to under 1 g/day. The third patient showed a considerable 30% reduction in proteinuria.
- XN treatment also led to an average decrease in creatinine levels by 0.23 mg/dl, indicating a positive effect on renal function.
- The findings suggest that XN shows promise as a treatment for IgAN. Larger studies are needed to confirm these results, but the initial outcomes indicate potential benefits in managing glomerulonephritis, especially in IgAN patients who are resistant to standard therapies.

Outstanding Contribution by Dr. Charareh Pourzand at Polyphenols Applications 2023
The Polyphenols Applications 2023 committee acknowledges Dr. Charareh Pourzand from the University of Bath, UK, for her exemplary achievement in securing the Best Short Oral Presentation Award.
In her presentation titled "Hydroxycinnamic Acid Derivatives as Dual-Action Antioxidants and Iron Chelators for Shielding Skin Cells from UVA Photodamage", Dr. Pourzand provided a comprehensive overview of her research findings. Among the multiple hydroxycinnamic acid derivatives studied, trans-cinnamic acid (TCA) emerged as particularly potent in its photoprotective efficacy against UVA in skin cells. This was attributed to its pronounced capability to reduce both basal and UVA-induced increase in intracellular labile iron levels. Dr. Pourzand elaborated on the dual mechanistic role of hydroxycinnamic derivatives, with a notable emphasis on TCA, in counteracting UVA-induced damage in skin cells.
In general, Dr. Pourzand's Research on UVA photobiology specially in relation to skin photoaging has revealed that UVA component of sunlight has a dual damaging effect on skin cells. In one hand it generates harmful reactive oxygen species (ROS) and on the other hand it promotes the release of harmful free iron that acts as a catalyst to exacerbate the damaging effect of ROS, leading to irreversible skin photodamage in the form of wrinkling, sagging, etc .
Dr. Pourzand stated: "To counteract this dual effect of UVA, we are in process of identifying natural compounds based on polyphenols that can not only neutralise the UVA-induced ROS but also mop the free iron released by UVA. Since the properties and the concentration of such polyphenols can significantly change in different seasons or locations, our future research is concentrated on designing 'bio-inspired' molecules that are more stable than their natural counterparts but still maintain their dual functions. Such bifunctional compounds can then be added as photo-protectants into sunscreen formulations for a more robust protection against UVA photodamge exerted by sunlight".
Such advancements in the field of skin photoprotection are of immense importance, and the Polyphenols Applications 2023 team, along with the broader scientific community, recognizes and appreciates Dr. Pourzand's significant contribution.

Natural polyphenol supplements reduce dietary iron absorption in adults with iron-loading diseases
Prof. Michael Bruce Zimmermann, ETH Zurich, Switzerland, will join the Polyphenols Applications 2023 Congress and present his latest rearch about the "Natural polyphenol supplements reduce dietary iron absorption in adults with iron-loading diseases".
Dr. Zimmermann and his colleagues developed a new natural polyphenol supplement that strongly chelates iron in vitro and assessed its effect on non-heme iron absorption in patients with hereditary hemochromatosis (HH). The polyphenol supplement reduced iron absorption by ~ 40% from meals and test drinks.
Their results indicate that when taken with meals, this natural polyphenol supplement can decrease dietary iron absorption, and might thereby reduce toxicity of body iron accumulation in patients with HH.

Polyphenol-Microbiome Interactions & Future of Nutrition
Dr. Tiffany Weir, Colorado State University USA, will join the Polyphenols Applications 2023 Congress and present her latest rearch about the interactions between polyphenols and the microbiome.
Although consumption of dietary polyphenols is widely acknowledged as beneficial for human health, there is a high degree of variability in individual responses. Some of this variability may be due to differential processing of dietary polyphenols by the gut microbiome. Polyphenol metabolizing enzymes in the gut microbiota can influence the bioactivity and bioavailability of these compounds.
Dr. Weir and her colleagues are working to understand whether these polyphenol metabolizing enzymes are predictive of individual responses in vascular endothelial function to a dietary blueberry intervention in post-menopausal women. More broadly, understanding polyphenol metabolism in the gut will advance precision nutrition and potentially help identify complementary approaches to improve outcomes to nutrition interventions.
Dr. Weir will give a presentation titled: "Polyphenol-Microbiome Interactions & Future of Nutrition"

Deglycosylation of secondary plant metabolites by lactobacilli
Prof. Michael Gänzle, University of Alberta, Canada, will join the Polyphenols Applications 2023 Congress and present his latest rearch about the "Deglycosylation of secondary plant metabolites by lactobacilli".
Lactobacillaceae are among the major fermentation organisms in food fermentations but their metabolic pathways for conversion of (poly)-phenolic compounds have been elucidated only in the past two decades. The first step of conversion is the hydrolysis of esters or glycosides of phenolic compounds. This study aimed to evaluate the ability of Lactobacillus crispatus FUA3540, Companilactobacillus paralimentarius FUA3121, Lacticaseibacillus paracasei FUA3413, Lactiplantibacillus plantarum TMW1.460, Levilactobacillus hammesii LP38T, Furfurilactobacillus rossiae FUA3124, and Ff. milii FUA3430T and Fructilactobacillus sanfranciscensis DSM20451T to hydrolyse glycosides of secondary plant metabolites.
The genomes of these strains encoded for 5, 20, 8, 10, 2, 1, 2 and 0 β-glucosidases or phospho‑β‑glucosidases, respectively. L. crispatus, Cp. paralimentarius, Lc. paracasei and Lp. plantarum but not Lv. hammesii, Ff. rossiae or Ff. milii hydrolysed cellobiose. The hydrolysis of amygladin, esculin, and salicin matched the hydrolysis of cellobiose. With exception of Fl. sanfranciscensis, all strains hydrolysed spiraeoside and genistin. Lp. plantarum and Cp. paralimentarius additionally hydrolysed isoquercetin.
Prof. Gänzle's data support the previous observation that many of the glycosyl hydrolases in lactobacilli are specific for glycosylated secondary plant metabolites rather than di- and oligosaccharides. Increased knowledge on their substrate specificity will facilitate the selection of fermentation organisms to secondary plant metabolites with desirable or undesirable biological activities in food fermentations.

Plant-Derived Polyphenols as Senolytic Agents
Cellular senescence is a basic aging process that drives several age-related degenerative conditions. Compounds that selectively eliminate senescent cells, commonly called “senolytics”, have the potential to improve multiple degenerative conditions by targeting this key age-promoting process.
Several polyphenols have been shown to have senolytic activity, including the hops-derived chalconoid xanthohumol, presenting a new pathway by which these molecules might improve degenerative disease.
Dr. Christopher Wiley from Tufts University, USA, will join the Polyphenols Applications 2023 congress and will present a talk entitled "Plant-Derived Polyphenols as Senolytic Agents".
About Dr. Wiley
Dr. Wiley is a Scientist II at the Jean Mayer USDA Human Nutrition Research Center on Aging and an Assistant Professor in the School of Medicine at Tufts University.

Multi-omics Approach Reveal Biomarkers of Metabolic Resilience in Healthy Participants Supplemented With Grape Polyphenols
Dr. Diana Roopchand from Rutgers University, USA, will join the Polyphenols Applications 2023 congress and will present a talk entitled "Multi-omics Approach Reveal Biomarkers of Metabolic Resilience in Healthy Participants Supplemented With Grape Polyphenols".
Grape polyphenols (GPs) extracted from grape pomace are rich in proanthocyanidins (PACs) compounds which are not bioavailable; however, evidence suggests their health benefits are likely mediated via the gut microbiota and/or bacterial metabolites.
Serum, fecal, and/or urine samples were collected before and after 2, 4, and 10 days of GP supplementation followed by shotgun metagenomic sequencing, mass spectrometry-based metaproteomics, and/or targeted metabolomics. Notable GP-induced bile acid changes appeared to be gender-specific and correlational analyses uncovered novel associations between gut microbes and metabolites associated with metabolic resilience.

Biological Activities of Phenol-Amino Acid Adducts: Towards enhancing Food Quality
Dr. Marianne Nissen Lund from the University of Copenhagen, Denmark will join the Polyphenols Applications 2023 congress and give a major presentation entitled "Biological Activities of Phenol-Amino Acid Adducts: Towards Enhancing Food Quality".
When polyphenols are oxidized to quinones they react with proteins in foods, with cysteine residues on proteins being kinetically preferred targets. Caffeic acid-cysteine and chlorogenic acid-cysteine adducts have been detected in commercial coffee-milk drinks. Thus, these adducts were synthesized and their anti-inflammatory activity was tested in lipopolysaccharide-treated RAW 264.7 cells in comparison to their parent phenolic acids.
Dr. Lund's results demonstrate that the addition of a cysteine moiety to phenolic acids enhances their anti-inflammatory responses in macrophages.
