Ovarian cancer cells were cultured for 24 hour by serum deprivation, and then were incubated for 24 hour with 100 ng/ml NGF, 10 uM Ro 08-2750+100 ng/ml NGF, 100 uM K252a+100 ng/ml NGF, 5 nM LM11A-31+ 100 ng/ml NGF, and 100 uM K252a+5 nM LM11A-31+100 ng/ml NGF. This evidence concerns the gene NGF and ovarian cancer.
