α-KG conformationally stabilizes nuclear GLUD1-SNAIL complex to fuel trans-endothelial migration in metastasis
Trans-endothelial migration (TEM) is a critical rate-limiting barrier in tumor metastasis, yet its mechanistic basis remains poorly defined. Here we show that α-ketoglutarate (α-KG) and its metabolic enzyme glutamate dehydrogenase 1 (GLUD1) constitute a pivotal regulatory axis governing this process. Mechanistically, G...
