G-quadruplexes (G4s) have arrested continuous interest in cancer research, and targeting G4s with small molecules has become an ideal approach for drug development. Plant-based dietary polyphenols have attracted much attention for their remarkable anti-cancer effects. Studies have suggested that polyphenols exhibit interesting scaffolds to bind G4s, which can effectively downregulate the proto-oncogenes by stabilizing those G4 structures. Therefore, this review not only summarizes studies on natural dietary polyphenols (including analogs) as G4 stabilizers, but also reveals their anti-cancer activities. Furthermore, the structural and antioxidant insights of polyphenols with G4s are discussed, and future development is proposed. These insights may pave the way for the development of the next generation of anti-cancer drugs targeting nucleic acids.

Unlabelled: Dietary fiber confers multiple health benefits originating from the expansion of beneficial gut microbial activity. However, very few studies have established the metabolic consequences of interactions among specific fibers, microbiome composition, and function in either human or representative animal models. In a study design reflective of realistic population dietary variation, fecal metagenomic and metabolomic profiles were analyzed from healthy dogs fed 12 test foods containing different fiber sources and quantities (5-13% as-fed basis).

The development of cardiometabolic (CM) diseases is associated with chronic low-grade inflammation, partly linked to alterations of the gut microbiota (GM) and reduced intestinal integrity. The SINFONI project investigates a multifunctional (MF) nutritional strategy's impact combining different bioactive compounds on inflammation, GM modulation and CM profile. In this randomized crossover-controlled study, 30 subjects at CM-risk consumed MF cereal-products, enriched with polyphenols, fibers, slowly-digestible starch, omega-3 fatty acids or Control cereal-products (without bioactive compounds) for 2 months.

Objective: Various plants have been reported to contain compounds that promote the transcriptional activity of Nuclear factor erythroid 2-related factor 2 (Nrf2) to induce a set of xenobiotic detoxifying enzymes, such as NAD(P)H-quinone acceptor oxidoreductase 1 (NQO1), via the antioxidant response element (ARE). While conventional methods for evaluating Nrf2 induction potency include measurement of NQO1 activity, an ARE luciferase reporter assay was recently developed to specifically assess Nrf2 induction potency of compounds of interest. In this study, we compared the abilities of these two assays to evaluate and determine Nrf2 induction potency of plant-derived compounds.

Autophagy, a vital cell process, has garnered attention for its role in various diseases and potential therapeutic interventions. Dysregulation of autophagy contributes to conditions such as metabolic diseases, neurodegenerative disorders, and cancer. In diseases such as diabetes, autophagy plays a crucial role in islet β-cell maintenance and glucose homeostasis, offering potential targets for therapeutic intervention.
