LAIR1 and ovarian cancer: We confirmed the effect of LAIR-1 on the malignant phenotypes of other ovarian cancer cells by stably overexpressing LAIR-1 in SKOV3, an ovarian cell line with lower level LAIR-1 expression, using a LAIR-1-lentivirus based on the cDNA sequence of LAIR-1 from HO8910 and COC1.
