Moreover, we assessed the expression of the full-length MTA1 (MTA1-FL) and the spliced variant MTA1dE4 in both tumor and non-tumor tissues, all of which were obtained by serial liver biopsy at different time points, and analyzed the correlation between them and the size of the tumor, as well as the result of serological assay (Figure 5). This evidence concerns the gene MTA1 and neoplasm.
