AI Article Synopsis

  • Fluorescent gold nanoparticles (AuNPs) are promising for biomedical uses due to their strong luminescence, stability, and low toxicity, and were conjugated to mechano-growth factor (MGF), which is linked to various cancers including prostate cancer.
  • AuNPs were used to study MGF expression in colon cancer cell lines and tissues, revealing their presence in cancerous samples but not in normal tissues or umbilical vein cells.
  • The findings suggest that MGF is overexpressed in colon cancer, indicating it could be a valuable target for imaging and drug delivery strategies in treating the disease.

Article Abstract

Background/aim: Fluorescent gold nanoparticles demonstrate strong photoluminescence, photostability, and low cellular toxicity, making them attractive agents for biomedical applications. Mechano-growth factor (MGF) is an isoform of IGF1 and its expression has been demonstrated in malignancies including prostate cancer.

Materials And Methods: Near-infrared-emitting gold nanoparticles (AuNPs) were synthesized and conjugated to MGF. Following characterization and confirmation of conjugation, these AuNPs were used to investigate the expression of MGF in colon cancer cell lines (HT29 and SW620) and tissues comparing normal and colon cancer. The prostate cancer cell line PC3 and adenocarcinoma tissues were used as positive controls.

Results: Colon cancer cell lines, adenocarcinoma tissues and polyp tissues demonstrated evidence of MGF peptide expression, which was not found in normal colon tissues and human umbilical vein endothelial cells.

Conclusion: MGF appears to be overexpressed in colon cancer tissues, offering a potential unique target for imaging and drug delivery in colon cancer.
