Flow cytometric analysis (Table 1, with representative plots in Figures S3–S9) revealed that the protein level percentages of p27, p21, and p53 in the tumor cells of mice post-treated with Thymax were upregulated relative to the tumor tissues of Inocul Control to record an increase of 2.4 fold, 4.4 fold, 2.4 fold, and 4.4 fold, respectively. Here, TP53 is linked to neoplasm.
