Project description:Glutamine deprivation enhances metabolic reprogramming during kidney organoid directed differentiation
| PRJNA523040 | ENA
Project description:In this study, we systematically performed comprehensive metabolite and transcriptome profiling of human pluripotent stem cells (hPSCs) during differentiation into NPCs and later into multicellular organoids. We found activation of distinct metabolic pathways during early stage progression from hPSCs to NPCs; however, NPCs, organoids, and the intervening developmental stages between them shared similar metabolic profiles across this later stage of maturation. Importantly, the Alanine-aspartate-glutamate and glutamine pathways were significantly altered during the first stages of differentiation. Moreover, hPSCs survived glutamine deprivation during in vitro differentiation, and NPCs were successfully generated both in the absence and presence of glutamine and glutamate. Surprisingly, metabolic deprivation resulted in enhanced maturation, specifically in podocytes, as evidenced through single cell RNA-Seq analysis. These findings highlight the critical regulatory role of glutamine metabolism in the derivation of nephron progenitor cells and kidney organoids.

Project description:To understand the effects of glutamine deprivation on cell physiology we performed global analysis of gene expression in response to glutamine deprivation. U2OS cells were subjected to glutamine deprivation for 24h followed by RNA extraction and microarray analysis. U2OS cells were plated overnight followed by treatment for 24h with glutamine-containing and glutamine-depleted media. Three biological replicates were assayed for each condition.

Project description:We applied the quantitative proteomics approach to estimate the relative abundance of proteins in HepG2 cells treated by glutamine deprivation. Two independent cultured cell lysates, namely control and glutamine deprivation, were marked with iTRAQ labels and subjected to LC-ESI-MS/MS analysis. The tryptic peptides of two samples were labeled with mass 113 (control) and 119 (glutamine deprivation) isobaric iTRAQ tags.

Project description:Metabolic pathways driving differentiation into nephron progenitor cells (NPCs) and renal organoids from the pluripotency stage remain poorly understood. In this study, we systematically performed comprehensive metabolite and transcriptome profiling of human pluripotent stem cells (hPSCs) during differentiation into NPCs and further into multicellular organoids. We found activation of distinct metabolic pathways during early-stage progression from hPSCs to NPCs; however, later-stage differentiation from NPCs to organoids, and the intervening developmental stages between them, largely shared similar metabolic profiles. Among the pathways changing in early differentiation, the alanine-aspartate-glutamate and glutamine pathways were found to be significantly altered by both an enrichment and by pathway impact analysis. Moreover, hPSCs survived glutamine deprivation during in vitro differentiation, and NPCs were successfully generated both in the absence and presence of glutamine and glutamate. Surprisingly, glutamine deprivation resulted in enhanced maturation, by accelerating PAX8 expression, and enriching for podocytes as detected through single cell RNA-Seq analysis. Taken together, these findings highlight a critical regulatory role of glutamine metabolism in the derivation of nephron progenitor cells and renal organoids and identify a controlling metabolic pathway of early renal differentiation.

Project description:There are two major subtype of cells in breast cancer. These cancer cells response differently to glutamine deprivation, here we use one luminal type of breast cancer cell (MCF7) and one basal type of breast cancer cell (MDAMB231) to compare the gene expression differences of these two types of cancer cells in glutamine deprivation. Many cancer cells depend on glutamine for survival and oncogenic transformation. Although targeting glutamine metabolism is proposed as novel therapies, their heterogeneity among different tumors is unknown. Here, we found only basal-type, but not luminal-type breast cancer cells, exhibited phenotypes of glutamine dependency and may benefit from glutamine-targeting therapeutics. The glutamine independence of luminal-type cells is caused by the specific expression of glutamine synthetase (GS), a pattern recapitulated in luminal breast cancers. The co-culture of luminal cells partially rescued the basal cells under glutamine deprivation, suggesting glutamine symbiosis. The luminal-specific expression of GS is directly induced GATA3 and down-regulates glutaminase expression to maintain subtype-specific glutamine metabolism. Collectively, these data indicate the distinct glutamine phenotypes among breast cells and enable the rational design of glutamine targeted therapies.
