Furthermore, real-time PCR assay confirmed this result, the levels of IFN-α, IFN-β, IRF7, and IFIT1 in MCF7 cell infected with rClone30-RFP or rAnh-RFP were significantly upregulated, while the level of Glioma tumor suppressor candidate region gene 2 (GLTSCR2) attenuated IFN-β and ST6GALI associated with the formation of α2,6-linked sialic acid was significantly downregulated (Fig. 3). Here, IFIT1 is linked to central nervous system cancer.
