POU2F3 and cervical cancer: It had been reported that human POU2F3 could promote keratinocyte proliferation (Hildesheim et al. 2001), however, the knockout mice study (Andersen et al. 1997) and the colony inhibition assay in cervical cancer cells (Yutaka et al. 2004) suggested POU2F3 might inhibit keratinocyte proliferation.
