Furthermore, when compared to human normal ovarian epithelium (HOSE II, HOSE 2282), western blot analysis revealed that PAF-AH IB2 was overexpressed in multiple ovarian cancer cell lines and was partially associated with LIS1 subunits overexpression in MCAS, SKOV3 and RMUGL (Fig. 2A), including MCAS, SKOV3, Tov112D, OVCA3, OVCA420, OVCA432, OVCA633, OVCA810 and RMUGL (Fig. 2A), but a negative signal in RMG1 cell. This evidence concerns the gene PAFAH1B1 and ovarian cancer.
