The effects of UVA photoirradiated Ce(Ⅳ) doped TiO2 nanoparticle (CDTP) on rat colon carcinoma cell line (C26) growth, cell cycle distribution, and morphology were studied by MTT assay, Flow Cytometry, and fluorescent staining. The results indicate that about 64.6% cells are killed after 24 h by 180 μg·ml-1 CDTP when 8 min exposed to UVA, over 90% dead for 30 min group, relative to 18.7%, 41.5% of TiO2 at the same condition respectively. Hoe 33258 staining of the fixed cells reveals typical apoptotic structures (apoptotic bodies), and cells are arrested in G0/G1 phase.
