Laboratory of Cellular and Molecular Physiology (LPCM)

Research unit - UR 4667


Since 2003, the LPCM has brought together lecturer-researchers and clinicians to study ionic homeostasis and its signalling in cancer.
The ambition of our laboratory is to develop translational research with clinicians on the role of ion channels in cancer.
The members of our laboratory have developed and created new university courses around this theme.
This dynamic allows the LPMC to attract the best students, who can both benefit from quality training and have their national and/or international mobility encouraged.

Our scientific work also consolidates research in oncogenesis in the region, and allows it to be anchored in the Cancéropôle Nord-Ouest.

In addition, the project can lead to an important contribution to understanding the role of these new markers and/or therapeutic targets, ionic channels, in cancer biology.

The LPCM, in association with the CHU Amiens-Picardie (the
Tumorothèque de Picardie and the Anatomie et Cytologie Pathologiques department) studies the role of ion channels in the cancer pathophysiology of the human mammary gland, as well as ion homeostasis in lung and pancreatic cancers.
The research unit thus contributes to the understanding of the role ́
of new markers and/or new therapeutic targets that are ion
channels in cancer biology.

The research carried out within the LPCM is structured around three axes:

• The impact of the hypoxic and acidic tumour environment and of extracellular matrix elements on cell survival and cell migration and invasion: involvement of the
Kv10.1/Orai1 couple, the TRPM7 channel and other ion transporters

• The Orai3/Stim1/IP3R complex in chemotherapy resistance and metastasis

• The TRPM7 «chanzyme» in the regulation of matrix
metalloproteinase secretion, magnesium homeostasis, and in the activation of pancreatic stromal cells and their interaction with pancreatic cancer cells

These three questions are complemented by translational
studies evaluating the role of ion channels as diagnostic, prognostic and/or therapeutic markers in human histopathology.
