Core Tip

Core tip: Hypoxia induces the de-differentiation of human non-small cell lung cancer cells into cancer stem cell-like cells, and TX-402, a small-molecule inhibitor of hypoxia-inducible factor (HIF)-1α and HIF-2α expression, suppresses this hypoxia-induced process and, importantly, the metastatic ability of the cells.
