Team description

We have recently observed that the functional expression of the SK3 channel is linked to cancer cell migration and bone metastasis development. Interestingly, the SK3 channel was expressed in tumor breast biopsies while its expression was not observed in non-tumor breast tissues. In parallel and with the establishment of several collaborations with chemists, biologists, oncologists and pathologists of « Cancéropôle Grand Ouest » we discovered inhibitors of the SK3 channel with anti-metastatic properties. Moreover, thanks to « Région Centre, Cancéropôle Grand Ouest » and « FEDER », we have set up a robotic platform of electrophysiological assays dedicated to discovering new components that modulate ion channel activities and that present anti-cancer properties.

Role in the network

Our team will explore the regulation of calcium influx by SK3 channel and its role in cancer. Our group will bring to the project its knowledge and skills on SKCa channel and on the development of robotic platform of electrophysiological assays.
