CAT expression in the rest of pancreatic carcinoma (IMIM-PC-2 and RWP-1), colorectal carcinoma (HT-29, SW-480, and SW-620) and glioblastoma (HGUE-GB-18, HGUE-GB-37, HGUE-GB-39, and HGUE-GB-42) cell lines were more than 80% lower than that observed in Hs766T (Figure 10A). The gene discussed is CAT; the disease is glioblastoma.
