Solid tumors possess unique microenvironments that are exposed to chronic hypoxic
conditions, so-called tumor hypoxia. Although more than half a century has passed since it
was suggested that tumor hypoxia correlated with bad treatment outcomes and contributed
to the recurrence of cancer, no fundamental solution to this problem has yet been found.

Solid tumors possess unique microenvironments that are exposed to chronic hypoxic conditions, so-called tumor hypoxia. Although more than half a century has passed since it was suggested that tumor hypoxia correlated with bad treatment outcomes and contributed to the recurrence of cancer, no fundamental solution to this problem has yet been found. Hypoxia-inducible factor HIF-1 is the main transcription factor that regulates the cellular response to hypoxia. It induces various genes, whose function is strongly associated with the malignant alteration of the entire tumor. The cellular changes induced by HIF-1 are extremely important therapeutic targets of cancer therapy, particularly in the therapy against refractory cancers. Therefore targeting strategies to overcome the HIF-1-active microenvironment are important for cancer therapy.
