Consistent with IHC results, YAP was highly expressed in cervical cancer cell lines (ME180, HT3, and HeLa), while in Ect1 cells, an immortalized epithelial cell line derived from the ectocervical epithelium, YAP protein was expressed at low levels and was highly phosphorylated (Appendix Fig S1A). Here, YAP1 is linked to cervical cancer.
