| 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. |

Collection:
| Collection ID: | CO002600 |
| Collection Summary: | The eye organoids were collected and washed twice with PBS before pellets were flash-frozen and stored at −80°C until metabolite extraction. Three biologically independent repeated samples were collected. |

| Sample Type: | Retina |
Treatment:
| Treatment ID: | TR002619 |
| Treatment Summary: | All the organoids (50 organoids per condition) were washed with blank SILAC before being reconstituted in 13C medium at a concentration of 10 eye organoids/ml The incubation was performed from 15 minutes to 2 hours for time-course analysis of the glucose labeling. |
Sample Preparation:
| Sampleprep ID: | SP002613 |
| Sampleprep Summary: | The eye organoids were collected and washed twice with PBS before pellets were flash-frozen and stored at −80°C until metabolite extraction. Metabolite analysis was performed as described previously (PMID: 33931446). Briefly, for metabolite extraction, 80% methanol was used followed by the rapid freeze-thaw method to break the tissues. The supernatant underwent speedvac drying. The samples were prepared in 80% acetonitrile and were analyzed by High-Resolution Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS). |
