First, we analyzed the effect of AMH concentration on cell survival in four AMHRII-positive ovarian cancer cell lines, COV434-AMHRII (sex cord stromal tumor), SKOV3-AMHRII (high grade serous adenocarcinoma), OVCAR8 (high grade serous adenocarcinoma), and KGN (granulosa cell tumor), using an MTS assay to measure cell viability and proliferation. The gene discussed is AMH; the disease is granulosa cell tumor.
