Colon 26 is a murine colon carcinoma cell line established in the mid-1970s. Its development marked a significant milestone in cancer research, providing a robust model system for studying colorectal cancer progression, metastasis, and therapeutic interventions. Colon 26 cells exhibit high tumorigenicity in syngeneic mouse models, making them valuable tools for preclinical studies.
The GFP/Luc Reporter Cell Line derived from Colon 26 integrates green fluorescent protein and luciferase reporter genes, enhancing its utility for in vivo imaging and monitoring tumor growth and metastasis. This modification enables non-invasive longitudinal tracking of tumor dynamics and response to treatment in live animals, facilitating the evaluation of experimental therapeutics and elucidation of underlying biological mechanisms.
The combination of Colon 26 and reporter gene technologies has revolutionized cancer research by providing a platform for real-time visualization and quantification of tumor behavior in preclinical models. This model system has greatly contributed to our understanding of colorectal cancer biology and has facilitated the development of novel therapeutic strategies.
Colorectal cancer (CRC) ranks third among the most commonly diagnosed cancers in men and second in women globally. Researchers have explored the potential of amine-functionalized graphene oxide nanoparticles (GO-NH2) for colorectal cancer therapy. Evaluating their impact on Colon 26 cells, we assessed ROS generation, cellular proliferation, and survival. Our findings indicate that exposure to aminated GO enhances cytotoxicity through ROS induction, DNA damage, and apoptosis, suggesting its potential as an effective anticancer agent. This research sheds light on the mechanism of action of GO-based therapies in cancer treatment.
