YBX1 integration of oncogenic PI3K/mTOR signalling regulates the fitness of malignant epithelial cells

Abstract

The understanding of molecular mechanisms in different subtypes of head and neck cancer (HNC) will define subtype-specific treatment options. Here the authors show that PI3K-phospho-YBX1 axis promotes tumour growth in basal subtype of HNC, while unphosphorylated YBX1 acts as a suppressor of metastasis in the mesenchymal subtype with inactive PI3K signalling.
