Expression of Drosophila neoplastic tumor suppressor genes discslarge, scribble, and lethal giant larvae in the mammalian ovary.

The similarities and differences in molecular mechanisms regulating invertebrate and mammalian folliculogenesis are starting to be deciphered. In Drosophila, the neoplastic tumor suppressor gene discslarge is crucial for suppressing proliferation and movement of follicle cells relative to the growing oocyte. Lethal giant larvae and scribble play similar roles and have been suggested to collaborate intimately with discslarge. We have identified and determined the expression pattern of murine homologs of these Drosophila genes. In situ data shows that murine discslarge-1, discslarge-3, discslarge-4, lethal giant larvae, and scribble are expressed in both overlapping and distinct patterns in oocytes and granulosa cells in maturing follicles. Disclarge-4 is expressed in the surface epithelium and is lost in mouse carcinogenic surface epithelial cells. All of these genes, as well as discslarge-2 and discslarge-5, are expressed in human ovaries. Our data suggests that as in Drosophila, these tumor suppressors may cooperate during mammalian folliculogenesis, but also have distinct functions.[1]
