Chetomin is a natural metabolite produced by several species of the genus Chaetomium. Chetomin disrupts the hypoxia-inducible factor (HIF) pathway, blockomg the interaction of HIF1α and HIF2α with transcriptional co-activators p300 and cAMP response element binding (CREB) binding protein (CBP), thereby attenuating hypoxia-inducible transcription. Disrupting the ability of tumors to adapt to hypoxia leads to decreased tumor growth; hypoxia can also promote resistance to radiotherapeutics. By both of these mechanisms, chetomin shows promise as a lead compound in antitumor research. Chetomin also suppresses the proliferation of LPS-induced mouse spleen lymphocytes.

Survival strategies adopted by tumor cells in response to a hypoxic stress include activation of hypoxia-inducible factor 1 (HIF-1) and autophagy. However, the importance and the function of each molecular response is not well defined. In the present study, we
Aberrant differentiation is a characteristic feature of neoplastic transformation, while hypoxia in solid tumors is believed to be linked to aggressive behavior and poor prognosis. However, the possible relationship between hypoxia and differentiation in malignancies remains poorly defined. Here we
Endothelin-1 (ET-1) is mainly secreted by endothelial cells and acts as a potent vasoconstrictor. In addition ET-1 has also been shown to have pleiotropic effects on a variety of other systems including adaptive immunity. There are two main ET-1 receptors
Hypoxia-inducible factor-1 (HIF-1) overexpression has been linked to tumor progression and poor prognosis. We investigated whether targeting of HIF-1 using chetomin, a disrupter of the interaction of HIF-1 with the transcriptional coactivator p300, influences the radiosensitivity of hypoxic HT 1080
