Our results showed that in HCC cell lines the protein expression of SSAT in SMMC7721, HepG2 cells was lower than in Bel7402 cells, while in colorectal carcinoma cells the protein expression of SSAT in HCT-116 cells was less than in HT-29 cells (Figure 1A). The gene discussed is SAT1; the disease is colorectal carcinoma.
