Hypoxia and faulty vasculature are well-known hallmarks of cancer and in addition to being associated with poor prognosis in patients, these hallmarks are also known to contribute to therapy resistance. In recent years, therapeutics that alleviate hypoxia and promote normalization of vasculature are being explored for cancer therapy. In addition to being hypoxic, cancers such as non-small cell lung cancers exhibit elevated oxidative phosphorylation. Therapeutic strategies that can normalize vasculature and reduce oxidative phosphorylation could greatly benefit the landscape of cancer therapeutics. Here, we highlight a heme-targeting therapeutic strategy that demonstrates significant tumor growth inhibition in non-small cell lung cancer mouse models using multi-spectral optoacoustic tomography.
