Immunoblots using an anti-ODC antibody showed that protein levels of ODC, spermidine/spermine N1-acetyltransferase (SAT1), and PAOX were high in CSCs in cervical cancer and osteosarcoma cell lines (see chemistry in Fig. 1b and results in Fig. 1c, S1a). The gene discussed is ODC1; the disease is cervical carcinoma.
