Hypoxia-induced metastatic heterogeneity in pancreatic cancer.

ABSTRACT: In most solid tumors, hypoxia is a critical physical attribute that reprograms malignant cells into a highly metastatic state. Specifically, hypoxia is a well-established inducer of cellular plasticity, which is associated with treatment resistance and metastasis. Furthermore, hypoxia exacerbates chromosomal instability (CIN), a hallmark of cancer that can be initiated by the loss of Trp53 and a key contributor to metastasis. Despite this, the mechanisms by which malignant cells concurrently co-opt these elements of hypoxic adaptation to promote metastasis remains unknown. Here we report that hypoxia promotes metastasis by suppressing the JmjC-containing histone lysine demethylase Kdm8. CRISPR/Cas9-mediated targeting of Kdm8 in a Kras;Trp53-driven mouse model of
