Turning agro-food waste into resources: Exploring the antioxidant effects of bioactive compounds bioaccessibility from digested jabuticaba tree leaf extract. Food Chem 2025; 469:142538. [PMID: 39708655 DOI: 10.1016/j.foodchem.2024.142538] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2024] [Revised: 09/27/2024] [Accepted: 12/15/2024] [Indexed: 12/23/2024]
Abstract
The jabuticaba tree leaf, considered an agro-food by-product or waste, was evaluated as a potential unconventional ingredient of bioactive compounds. Its hydroalcoholic extracts were assessed for the phenolic chemical profile by LC-QQQ-MS and antioxidant capacity pre- and post-gastrointestinal digestion (i.e., bioaccessibility), along with determining cytotoxicity effects on cell culture, antihaemolytic and cellular antioxidant activity. A total of 9 phenolic compounds, including ellagic acid and flavonoids (hesperidin) were identified in both crude and digested samples. The bioaccessibility of these compounds was increased after digestion process, which was reflected in the erythrocytes' antioxidant activities, reducing the haemolysis, lipid peroxidation and reactive oxygen species (ROS) generation by more than 50 %. Furthermore, the in vitro digestion diminished the cytotoxicity effect, increasing the cell viability by 71 %. These findings underscore the potential of jabuticaba tree leaf extract as a rich source of antioxidant phenolics, emphasizing their potential and promising applications as a new functional ingredient.

Sci Rep 2024; 14:11535. [PMID: 38773159 PMCID: PMC11109164 DOI: 10.1038/s41598-024-60347-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2023] [Accepted: 04/22/2024] [Indexed: 05/23/2024] Open
Abstract
In this study, a novel method for the fabrication of hesperidin/reduced graphene oxide nanocomposite (RGOH) with the assistance of gamma rays is reported. The different RGOHs were obtained by varying hesperidin concentrations (25, 50, 100, and 200 wt.%) in graphene oxide (GO) solution. Hesperidin concentrations (25, 50, 100, and 200 wt.%) in graphene oxide (GO) were varied to produce the various RGOHs. Upon irradiation with 80 kGy from γ-Ray, the successful reduction of GO occurred in the presence of hesperidin. The reduction process was confirmed by different characterization techniques such as FTIR, XRD, HRTEM, and Raman Spectroscopy. A cytotoxicity study using the MTT method was performed to evaluate the cytotoxic-anticancer effects of arbitrary RGOH on Wi38, CaCo2, and HepG2 cell lines. The assessment of RGOH's anti-inflammatory activity, including the monitoring of IL-1B and IL-6 activities as well as NF-kB gene expression was done. In addition, the anti-invasive and antimetastatic properties of RGOH, ICAM, and VCAM were assessed. Additionally, the expression of the MMP2-9 gene was quantified. The assessment of apoptotic activity was conducted by the detection of gene expressions related to BCl2 and P53. The documentation of the JNK/SMAD4/MMP2 signaling pathway was ultimately accomplished. The findings of our study indicate that RGOH therapy has significant inhibitory effects on the JNK/SMAD4/MMP2 pathway. This suggests that it could be a potential therapeutic option for cancer.

[PMID: 34638619 PMCID: PMC8508681 DOI: 10.3390/ijms221910278] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2021] [Revised: 09/19/2021] [Accepted: 09/20/2021] [Indexed: 11/26/2022] Open
Abstract
Colon cancer is accompanied by a decrease of epithelial barrier properties, which are determined by tight junction (TJ) proteins between adjacent epithelial cells. The aim of the current study was to analyze the expression of TJ proteins in a rat model of 1,2-dimethylhydrazine (DMH)-induced colorectal cancer, as well as the barrier properties and TJ protein expression of IPEC-J2 cell monolayers after incubation with DMH. Transepithelial electrical resistance and paracellular permeability for sodium fluorescein of IPEC-J2 were examined by an epithelial volt/ohm meter and spectrophotometry. The expression and localization of TJ proteins were analyzed by immunoblotting and immunohistochemistry. In the colonic tumors of rats with DMH-induced carcinogenesis, the expression of claudin-3 and -4 was significantly increased compared to controls. The transepithelial electrical resistance of IPEC-J2 cells increased, while paracellular permeability for sodium fluorescein decreased, accompanied by an increased expression of claudin-4. The increase of claudin-4 in rat colon after chronic DMH exposure was consistent with the acute effect of DMH on IPEC-J2 cells, which may indicate an essential role of this protein in colorectal cancer development.
