However, in SiHa-Msi1 cells, Msi1 protein kept a strong binding at 3′UTR binding sites of p21, p27–1 and p53–1; but kept a relatively weak binding at the sites of p27–2 and p53–2, suggesting that Msi1 may have the different effects on target genes in different cervical cancer cell lines. Here, MSI1 is linked to cervical carcinoma.
