| Outline of Final Research Achievements |
Fragile X syndrome (FXS) is a hereditary disease that causes mental retardation most frequently. Mutations in Fragile X mental retardation 1 (Fmr1) have been identified as the causative agent of FXS. It has been reported that ~20% of female carriers of pre-mutations in Fmr1 developed fragile X-associated premature ovarian failure (POF) or tremor/ataxia syndrome. However, it is not determined how Fmr1 impacts these disorders. Based on novel protein-protein interactions via a cell size-controlling gene product and other original observations, this investigator hypothesized that the targets of Fmr1 were modulated differentially in brain and ovary through the interactions among the proteins. Experiments using mice and cultured cells supported the hypothesis, and thus further investigations carried out to identify an ovary-specific genetic cascade of Fmr1.
