FIGURE 7

Loss of MAPK signaling response to EGF in egfra mutant ovary. (A) EGF treatment of ovarian fragments in vitro induced phosphorylation of MAPK3/1 (Erk1/2) in egfra+/− but not egfra−/− follicles. However, the mutant ovary showed higher basal level of MAPK phosphorylation despite its lack of response to EGF. (B) Immunohistochemical staining for MAPK3/1 phosphorylation in the control and mutant ovaries without EGF treatment. High level of phosphorylated MAPK3/1 was located in the somatic follicle cells of the egfra−/− ovary. (C) Increased expression of chemokine ligands (ccl25b, ccl34b.1, ccl34b.8, and ccl35.2) in egfra−/− follicles.
