The GMRI has previously demonstrated the putative presence of two cancer stem cell (CSC) subpopulations within moderately differentiated oral tongue squamous cell carcinoma (MDOTSCC), which express components of the renin–angiotensin system (RAS).

In this study we investigated the expression and localisation of the proteases cathepsins B, D, and G in relation to these CSC subpopulations within MDOTSCC.

We identified the presence of cathepsins B and D in the CSCs and cathepsin G on what are phenotypically mast cells. The identification of these suggests the presence of bypass loops for the RAS. Consistent with our other findings with respect to the control of the RAS, this represents an additional area of regulation as part of a novel therapeutic target for MDOTSCC.

There are numerous reports showing that cancer patients who are treated with medications that control the renin-angiotensin system, such as anti-hypertension drugs, have better survival from cancer and a lower risk of developing cancer.

The GMRI has demonstrated the presence of cancer stem cells – considered to be the origin of cancer – in many different types of cancers including glioblastoma, the most aggressive form of brain cancer. We have also shown that the cancer stem cells in glioblastoma possess the constituents of the renin-angiotensin system.

Earlier research undertaken by the team at the Gillies McIndoe Research Institute has identified and characterised cancer stem cells in tongue cancer, buccal mucosal (inner cheek) cancer, and lip cancer. The team has also shown that cancer stem cells in tongue cancer and buccal mucosal cancer express the renin-angiotensin system.
