Moreover, tumors from TGFBR1-CACcre ovaries were highly proliferative (Figure 4O, 4R, 4U, 4X and Figure S6E, H, G, J, O, and P), expressed granulosa cell markers FOXL2 (Figure 4P and 4S) and INHA (Figure 4Q, 4T, 4V, and 4Y and Figure S6F, I, G, J, Q, and R), and were immunoreactive for KRT8 during tumor progression (Figure 4W and 4Z and Figure S6S and T). Here, FOXL2 is linked to neoplasm.
