The levels of OS and changes in tumor cell proliferative capacity were assessed through western blotting, immunoblotting, ROS detection, and cell viability assays.<h4>Results</h4>The study revealed that <i>CCND1</i> and <i>SOX4</i> were highly expressed in PTC, promoting tumor cell proliferation, invasion, and maintaining an undifferentiated state. This evidence concerns the gene CCND1 and neoplasm.
