CDK2 and neoplasm: To investigate the potential mechanism of the anti-tumor activity of brown seaweed polysaccharides, we chose the SHP-1.7/HeLa combination as a research model to examine the expression levels of genes related to tumor apoptosis and growth, including Caspase-3, Caspase-8, Caspase-9, Bax, Bcl-2, and CDK-2, using quantitative real-time PCR (qRT-PCR).
