Savelkouls, Johan Bussink, Albert J. van der Kogel, Marianne Koritzinsky, Bradly G. Wouters Background and purpose: Tumour hypoxia is an important limiting factor in the successful treatment of cancer. Adaptation to hypoxia includes inhibition of mTOR, causing scavenging of eukaryotic initiation factor 4E (eIF4E), the rate-limiting ... Read More

“Hypoxia signalling through mTOR and the unfolded protein response in cancer” Nature Rev. Cancer, 2008

Bradly G. Wouters & Marianne Koritzinsky  Abstract Hypoxia occurs in the majority of tumours, promoting angiogenesis, metastasis and resistance to therapy. Responses to hypoxia are orchestrated in part through activation of the hypoxia-inducible factor family of transcription factors (HIFs). Recently, two additional O2-sensitive signalling pathways have also been implicated: signalling through the mammalian target of rapamycin ... Read More
