Research Interests :
- Hypoxia signaling & nutritional stress in cancers
- Carbonic anhydrases, Bicarbonate transporters and H+/Lactate symporters (MCTs)
- Amino Acid transporters and mTOR control
- Genetic validation of anticancer targets

Over the years, Pouyssegur’s group has combined genetics and molecular biology to study the mechanisms of action of growth factors and has characterized the major signaling pathways controlling cell proliferation. His team has made substantial contributions to the areas of cell surface glycoproteins, metabolism, intracellular pH regulation, identification of human Na/H exchangers and establishment of intracellular pH and MAP kinase (ERKs) signaling as critical components for cell cycle entry.

During the last 18 years the group has turned its interest to another essential growth mechanism: how do cells control their growth and survival under low nutrient supply? This key process has led the team to investigate mechanisms of hypoxia signaling, angiogenesis, nutritional stress and aberrant metabolism in tumours.

Currently Pouyssegur’s group pursues, at a fundamental level, the physiological role for key targets induced by nutritional stress and hypoxia in tumours. The focus is on aberrant glucose metabolism in tumours (Warburg effect), glycolysis, pH regulation, autophagy, and nutrient import driven by HIF/NRF2 with a special interest in translational research. Numerous potential anticancer targets disrupted by ZFN & CRISPR have been validated (carbonic anhydrases CA9, CA12, CA2, Na-bicarbonate co-transporter NBC, Na-H exchanger NHE1). Other potential anticancer targets disrupted by CRISPR are currently being validated in preclinical mouse models by the team including MonoCarboxylate Transporters (MCT1, MCT4) and their chaperone CD147/Basigin, which control the rate of glycolysis (Marchiq et al. Cancer Res, 2015). Finally, the team has started to explore via genetic disruption the key role of three amino acid transporters: LAT1/CD98, transporting essential amino acids (Parks et al. Mol. Aspects Med. 2016; Cormerais et al. Cancer Res, 2016), the glutamine transporter ASCT2 and the cystine transporter xCT/CD98 in the acquired resistance to reactive oxygen species. These targets all share a common participation to the ‘Darwinian’ tumour selection and progression within the hypoxic/oxidative, acidic and nutrient deprived tumour microenvironment.
