Special Issue Information

Dear Colleagues,

Amidst the growing health consciousness globally, bioactive food compounds have garnered significant attention for their potential in promoting human health. These compounds, naturally occurring in plants, animals, and their processed products, exhibit diverse biological activities such as antioxidant, anti-inflammatory, and antibacterial effects, contributing significantly to the prevention and management of chronic diseases. With advancements in molecular biology, genomics, and metabolomics, our understanding of the mechanisms underlying the health benefits of bioactive food compounds has significantly deepened.

This Special Issue aims to provide a contemporary understanding of the multifaceted relationships between diverse bioactive compounds in food and human health, encompassing their health-promoting effects and potential health risks. These bioactive compounds encompass nutrients such as vitamins and minerals, non-nutrient bioactive constituents like phytochemicals and functional peptides, as well as special bioactive compounds including probiotics, prebiotics, and a range of natural plant extracts.

In this Special Issue, original research articles, reviews, and short communications are welcome. We invite researchers, scientists, and industry experts from food and nutritional sciences to share their expertise and contribute to this Special Issue.

Background: Radioresistance remains a significant obstacle in lung cancer radiotherapy, necessitating novel strategies to enhance therapeutic efficacy. This study investigated the radiosensitizing potential of a soybean lecithin–gallic acid complex (SL–GAC) in non-small cell lung cancer (NSCLC) cells and explored its underlying ferroptosis-related mechanisms. SL–GAC was synthesized to improve the bioavailability of gallic acid (GA), a polyphenol with anticancer properties. Methods: NSCLC cell lines (A549 and H1299) and normal bronchial epithelial cells (BEAS-2B) were treated with SL–GAC, ionizing radiation (IR), or their combination. Through a series of in vitro experiments, including cell viability assays, scratch healing assays, flow cytometry, and Western blot analysis, we comprehensively evaluated the effects of SL-GAC on NSCLC cell proliferation, migration, oxidative stress, and ferroptosis induction. Results: SL–GAC combined with IR synergistically suppressed NSCLC cell proliferation and migration, exacerbated oxidative stress via elevated ROS and malondialdehyde levels, and induced mitochondrial dysfunction marked by reduced membrane potential and structural damage, whereas no significant ROS elevation was observed in BEAS-2B cells. Mechanistically, the combination triggered ferroptosis in NSCLC cells, evidenced by iron accumulation and downregulation of Nrf2, SLC7A11, and GPX4, alongside upregulated ACSL4. Ferrostatin-1 (Fer-1), a ferroptosis inhibitor, reversed these effects and restored radiosensitivity. Conclusions: Our findings demonstrate that SL–GAC enhances NSCLC radiosensitivity by promoting ferroptosis via the Nrf2/SLC7A11/GPX4 axis, highlighting its potential as a natural radiosensitizer for clinical translation.

Background: Protein hydrolysates from insects are recognized for their biological activities. Black soldier fly larvae (BSFL) have drawn attention due to their antioxidant protein hydrolysates. However, research on bioactive peptides derived from these hydrolysates, particularly their cancer chemopreventive potential, remains limited. This study aims to evaluate the antioxidant, anti-inflammatory, antimutagenic, and anticancer activities of BSFL-derived bioactive peptides and explore the molecular mechanisms. Methods: Alkali-soluble BSFL protein (ASBP) was extracted and hydrolyzed using Alcalase and bromelain under optimized conditions. Antioxidant activity was assessed via FRAP, ABTS, and DPPH assays. The hydrolysate with the highest antioxidant activity was fractionated into molecular weight (MW) groups (>30, 10, and <3 kDa). The bioactivity of fractionated peptides was evaluated through antioxidant, anti-inflammatory (nitric oxide production in RAW 264.7 cells), antimutagenic (Ames test), and anticancer (CCK-8 assay on HCT 116, COLO205, Cw-2, and Caco-2 cells) assays. Mechanistic insights were obtained via microarray and Western blot analyses. Peptides were identified by LC-MS/MS. Results: The ASBP-Alcalase hydrolysate (ASBP-AH) showed optimal antioxidant activity at 3% (w/w) for 4 h. The ASBP-AH 30 (MW > 30 kDa) fraction exhibited the highest antioxidant capacity. In contrast, the ASBP-AH3 (MW < 3 kDa) fraction exhibited significant antimutagenic effects, reduced nitric oxide production, and decreased COLO205 cell viability. Treatment with ASBP-AH3 at its LC50 dose modulated the SKP2/p21/cyclin D1 pathways. Mostly peptides from ASBP-AH3 were composed of hydrophobic and charged amino acids. Conclusions: BSFL-derived bioactive peptides exhibit potential as multifunctional agents for cancer chemoprevention. In vivo studies are required to explore their clinical applications. Full article
