Cancer Biology, Ageing, Genomics and Bioinformatics

Cancer is one of the leading causes of death, in particular in modern societies since age is the key risk factor for most types of tumours. Even though many cancer-related genes have been identified, new diagnostic and molecular targets are of great importance. The post-genome era has made possible large-scale molecular analysis of tumours and cancer cell lines. Indeed, massive amounts of data, such as microarray data, have already been generated in oncogenomics and are available in public databases. We are taking advantage of these datasets together with algorithms and bioinformatics pipelines to gain new insights on cancer, which we can then test experimentally. Moreover, we are interested in helping unravel the relationship between cancer and ageing.

In one project, we employed a computational candidate gene prioritization method developed in our lab, called GeneFriends, to identify new candidate cancer-related genes which we then validated experimentally. The unstudied C1ORF112 gene, in particular, appears to be overexpressed in various tumors and is important for growth of cancer cell lines, and thus we are currently further studying this gene and its protein product.

We are also studying the naked mole-rat, a long-lived, cancer-resistance rodent which may give insights into human cancer resistance.

In a previous project, we performed a genome-wide scan to identify genes whose expression across healthy organs correlates with mass-normalized, organ-specific cancer incidence.
