Raman Spectroscopy Analysis of The Temporal Heterogeneity in Lung Cell Carcinogenesis Induced by Benzo(a)pyrene
Objective Temporal heterogeneity in lung cancer presents as fluctuations in the biological characteristics,genomic mutations,proliferation rates,and chemotherapeutic responses of tumor cells over time,posing a significant barrier to effective treatment.The complexity of this temporal variance,coupled with the spatial diversity of lung cancer,presents formidable challenges for research.This article will pave the way for new avenues in lung cancer research,aiding in a deeper understanding of the temporal heterogeneity of lung cancer,thereby enhancing the cure rate for lung cancer.Methods Raman spectroscopy emerges as a powerful tool for real-time surveillance of biomolecular composition changes in lung cancer at the cellular scale,thus shedding light on the disease's temporal heterogeneity.In our investigation,we harnessed Raman spectroscopic microscopy alongside multivariate statistical analysis to scrutinize the biomolecular alterations in human lung epithelial cells across various timeframes after benzo(a)pyrene exposure.Results Our findings indicated a temporal reduction in nucleic acids,lipids,proteins,and carotenoids,coinciding with a rise in glucose concentration.These patterns suggest that benzo(a)pyrene induces structural damage to the genetic material,accelerates lipid peroxidation,disrupts protein metabolism,curtails carotenoid production,and alters glucose metabolic pathways.Employing Raman spectroscopy enabled us to monitor the biomolecular dynamics within lung cancer cells in a real-time,non-invasive,and non-destructive manner,facilitating the elucidation of pivotal molecular features.Conclusion This research enhances the comprehension of lung cancer progression and supports the development of personalized therapeutic approaches,which may improve the clinical outcomes for patients.
