Webb12 apr. 2024 · This approach enabled the researchers to induce genetic mosaicism in NPCs, allowing NPCs to carry different fluorescent proteins, and to track cell fate during the developmental continuum. Using this method, they identified two key regulators, Axin2 and p53, which are involved in driving cell-cell competitive interaction. WebbThe p53 protein is a transcription factor (Kastenhuber & Lowe 2024). Under normal conditions, the concentration of the p53 protein in a cell is very low because the protein has a half-life of 6–20 min. This is accomplished by the E3 ubiquitin ligase MDM2 (Momand et al. 1992).
