Probiotic-based derived exopolysaccharide-zinc oxide nanoparticles: a novel approach to colorectal cancer gene modulation
The second deadliest cancer in the world is colorectal cancer (CRC), which is caused by the uncontrolled proliferation of epithelial cells in the colon. This research examines the role of key genes—including tumor suppressors ING4 and APC, angiogenesis-related DHX32, and the oncogenic mutated P53—in the SW480 cell line. Probiotics and their exopolysaccharide (EPS) component show potential in cancer prevention and treatment due to their antioxidant and anti-cancer properties. Zinc oxide nanoparticles (ZnONPs), recognized for their unique physical and chemical characteristics, have broad applications in drug delivery, cancer diagnostics, and therapy. In this project, EPS was extracted from Lactiplantibacillus plantarum and used for ZnONPs biosynthesis, followed by characterization through UV–VIS, XRD, FTIR, FE-SEM, and zeta potential analysis. Cytotoxic effects of EPS and ZnONPs were evaluated on SW480 cells, along with their antioxidant properties. Quantitative real-time PCR analysis revealed decreased expression of DHX32 and P53, while ING4 and APC gene expression increased following treatment of the cancerous cell line with target agents. These findings suggest that probiotic-derived EPS and ZnONPs may offer effective strategies for CRC treatment by modulating critical gene expression involved in disease progression.
期刊介绍:
Bioorganic Chemistry publishes research that addresses biological questions at the molecular level, using organic chemistry and principles of physical organic chemistry. The scope of the journal covers a range of topics at the organic chemistry-biology interface, including: enzyme catalysis, biotransformation and enzyme inhibition; nucleic acids chemistry; medicinal chemistry; natural product chemistry, natural product synthesis and natural product biosynthesis; antimicrobial agents; lipid and peptide chemistry; biophysical chemistry; biological probes; bio-orthogonal chemistry and biomimetic chemistry.
For manuscripts dealing with synthetic bioactive compounds, the Journal requires that the molecular target of the compounds described must be known, and must be demonstrated experimentally in the manuscript. For studies involving natural products, if the molecular target is unknown, some data beyond simple cell-based toxicity studies to provide insight into the mechanism of action is required. Studies supported by molecular docking are welcome, but must be supported by experimental data. The Journal does not consider manuscripts that are purely theoretical or computational in nature.
The Journal publishes regular articles, short communications and reviews. Reviews are normally invited by Editors or Editorial Board members. Authors of unsolicited reviews should first contact an Editor or Editorial Board member to determine whether the proposed article is within the scope of the Journal.
