Publication number: 20090123934Abstract: Matrimony (Mtrm) acts as a negative regulator of Polo kinase (Polo) during the later stages of G2 arrest. Indeed, both the repression of Polo expression until stage 11 and the inactivation of newly synthesized Polo by Mtrm until stage 13 play critical roles in maintaining and properly terminating G2 arrest. Our data suggest a model in which the eventual activation of Cdc25 by an excess of Polo at stage 13 triggers NEB and entry into prometaphase. In view of the foregoing, methods for modulating oocyte maturation are provided. More particularly, methods are provided for in vitro maturation of an oocyte. Further provided are methods for identifying functional orthologs of a Drosophila Matrimony polypeptide, as well as inhibitors thereof.Type: ApplicationFiled: October 17, 2008Publication date: May 14, 2009Inventors: Youbin Xiang, Sue Jaspersen, Laurence Florens, Sarah Kendall Smith, R.

Patent number: 6054991Abstract: In a virtual reality system (20) an operator perceives being in a virtual reality world (74) of virtual reality images (62). The system (20) models the relative position and movement of objects (208 and 210) in a virtual reality world (74) by representing graphically a first (208) and second (210) object in a virtual reality world (74) on a graphical display (60 and 68). The representation selective obscures the first (208) and second (210) objects according to the relative position of the objects (208 and 210) to a predetermined observation point in the virtual reality world (74). The system (20) then determines a first partitioning plane (204) between the first (208) and second (210) objects. Then, the system (20) method determines a second partition plane (206) between the first (208) and second (210) object in response to either of said first (208) or second (210) objects moving across the first partitioning plane (204).Type: GrantFiled: July 29, 1994Date of Patent: April 25, 2000Assignee: Texas Instruments IncorporatedInventors: Christopher Adam Crane, Tom J.
