| Outline of Final Research Achievements |
We found that PGAM1 and 2 mediate function of RB tumor suppressor to regulate glycolysis. We also clarified how RB controls transcription of these genes. A further study demonstrated that PGAMs mediate RB function to control differentiation. On the other hand, we investigated the clinical significance of the RB function to control cholesterol synthesis. RB loss via increasing cholesterol synthesis recruits androgen receptor (AR) to nucleus and reduces ROS. These phenomenons were antagonized addition of statins, Lastly, we performed lipidomics analysis of RB-inactivated cells, which indicated that RB status gives significant impact on the quantitative and qualitative status of fatty acids,
