| Study Title | Time-course analysis of C13 labeling in mouse eye organoids. |
| Study Summary | The direct quantification of glucose consumption using 13C glucose time-course tracing was performed in cultured eye organoids and measured by LC-MS/MS analysis. The incubation was performed from 15 minutes to 2 hours. Cell Name AES0145 : Rx-GFP K/I EB5 (RIKEN Cell Bank): Organoid method (PMID: 21475194). |

| Project Title: | Lactate-dependent Transcriptional Regulation Controls Mammalian Eye Morphogenesis |
| Project Summary: | Mammalian retinal metabolism favors aerobic glycolysis. However, the role of glycolytic metabolism in retinal morphogenesis remains unknown. Here we report that aerobic glycolysis is necessary for the early stages of retinal development. Taking advantage of an unbiased approach that combines the use of eye organoids and single-cell RNA sequencing we identified specific glucose transporters and glycolytic genes in retinal progenitors. Next, we determined that the optic vesicle territory of mouse embryos displays elevated levels of glycolytic activity. At the functional level, we found that removal of Glut1 (also known as Slc2a1) and Lactate dehydrogenase A (Ldha) gene activity from developing retinal progenitors arrested eye morphogenesis. Surprisingly, we uncovered that lactate-mediated upregulation of key eye-field transcription factors was controlled by the epigenetic modification of histone H3 acetylation through histone deacetylase (Hdac) activity. Our results identify a novel bioenergetic independent role of lactate as a signaling molecule necessary for mammalian eye morphogenesis. |
