We found that DMAP1, ENY2, GADD45A, PHC2, SMARCAL1, and TRIM28 expression was significantly elevated and HCFC2, RCOR1, and TLE2 expression significantly decreased in tumor tissue relative to normal tissue, with no difference in EPC1 expression observed between tissue types (Figure 2A). The gene discussed is GADD45A; the disease is neoplasm.
