Cancer remains one of the greatest scourges of human society and the multifarious ways cancer cells continuously mutate and evolve to elude physiological checks and controls present one of the greatest challenges in medicine.

Tumours are highly heterogeneous growth consisting of cancer cells intermingled with blood vessels and stromal cells. The cancer cell population itself is a constellation of different cell types contributing to the unique histopathological features of specific cancers.

In GIS, a dynamic complementation of expertise in cancer biology, stem cell and developmental biology, genomics technology and bioinformatics established the backdrop to some of our most exciting and new discoveries about the cellular and genetic drivers of tumour growth.

A careful tracking of clues from murine knockout models, for example of p63, has led us to the first description of residual embryonic cells that are likely the precursors of metaplasia, the earliest prequel to several aggressive epithelial cancers.

Most recently, we described the isolation of tumour initiating cells for lung cancer capable of proliferating, self renewal and differentiating. Deeper genomic analysis of the molecular signature of these cells led to the discovery of a previously unknown serine-glycine pathway recruited by many types of cancers. Our discovery heightens the increasing focus and excitement around cancer metabolism and metabolic targets. It also lends significant support to the hotly debated notion that cancer growth and phenotype is driven mainly by a subpopulation of cancer stem cells.

In GIS we are expanding our studies into several major cancers including colon, breast, liver and ovarian cancers together with our programme on isolating and characterising circulating tumour cells. Fuelling these studies are our discoveries of an increasing number of molecular drivers of cancer stem cells, such as PDK-1, and the application of exciting new development in single cell genomic technologies that allow deep inquiry into the DNA and RNAs of single cell. Our expectations are that research into the cellular and molecular biology of cancer stem cells will have a significant impact in improving the control and elimination of many cancers.
