RT-PCRs of Notch 1 mRNA in SK-OV-3 cells showing that follicular stimulating hormone (FSH) increases the gene expressions of Notch 1 in a dose dependent pattern. The lanes mean the concentration of the FSH 0, 1, 5, 10, 50, 100, 200, and 300 mIU/mL respectively. *statistically significant, p<0.05, †,‡statistically significant, p<0.01.
