| Study Title | Glucose-6-phosphate-dehydrogenase on old peroxisomes maintains self-renewal of epithelial stem cells after asymmetric cell division |
| Study Summary | Peroxisomes play a crucial role in cellular metabolism. Glucose-6-phosphate dehydrogenase (G6PD), the gatekeeper enzyme of the pentose phosphate pathway, is primarily localized in the cytosol. However, studies have reported its presence in peroxisomes as well. This project aims to determine the function of G6PD on the peroxisomal membrane. In this study, we overexpressed G6PD in either the cytosol or on the peroxisomal membrane of mammary epithelial stem-like cells (hMECs). By comparing their lipidomic profiles, we found that peroxisomal membrane-associated G6PD provides NADPH, which feeds into peroxisomal ether lipid synthesis. |
