Knockout mouse technology has been used over the last decade to define the essential roles of ovarian-expressed genes and uncover genetic interactions. In particular, we have used this technology to study the function of multiple members of the transforming growth factor-beta superfamily including inhibins, activins, and growth differentiation factor 9(More)
The ovulatory process is tightly regulated by endocrine as well as paracrine factors. In the periovulatory period, extensive remodeling of the follicle wall occurs to allow the extrusion of the oocyte and accompanying cumulus granulosa cells. Growth differentiation factor-9 (GDF-9) and bone morphogenetic protein-15 (BMP-15) are secreted members of the(More)
The transcription factor achaete-scute homologue-1 (ASH1) is essential for neural differentiation during fetal development and is a cardinal feature of neuroendocrine (NE) tumors such as small cell lung cancer. To explore the potential of ASH1 to promote NE differentiation and tumor-igenesis in the lung, we constitutively expressed the factor in(More)
