Other reports support the importance of STAT1 in the control of tumor growth; for example, Lei et al. showed that the treatment of HeLa cells with cisplatin increases the expression of STAT1 and that the silencing of STAT1 with small interfering RNA (siRNA) promotes cell proliferation and rescues the tumor cells treated with cisplatin, which shows that the expression of STAT1 is essential for the induction of death in tumor cells [86]. Here, STAT1 is linked to neoplasm.
