Structure responsible for the research project
Colorectal cancer (CRC) is a relevant cause of morbidity and mortality. TRPM8, a member of the TRP channels superfamily, is up-regulated in a number of tumours. However, its role in colon carcinogenesis
(CC) is largely unexplored.
We will examine the role of TRPM8 in CC by using an integrated multidisciplinary preclinical approach comprising mouse models of CC (colitis-associated cancer, APC mice and xenograft model), pharmacological experiments in CRC cells (including in 5-fluorouracil-resistant cells) and assays (TRPM8 expression) in colonic samples and blood from stage I-IV CRC patients. We will also evaluate: i) possible changes in gut microbiota associated to TRPM8 modulation ii) the possible chemopreventive effect of a diet containing safe naturally-occurring TRPM8 ligands.
Our proposal is supported not only by literature data, but also by our preliminary (unpublished) pharmacological results on a mouse model of CC and on TRPM8 expression in colonic samples from CRC
