Normal-to-malignant cell transformation may be underlain by many different mechanisms that typically share a single common feature – the alteration of genetic information and subsequent disruption of cellular regulatory mechanisms, which thus lead to uncontrolled proliferation. Some of these genetic alterations have been described already and are routinely analysed in oncological diagnostics, e.g. TP53, ATM or BRCA1/2 gene mutations or specific translocations occurring in leukemias, lymphomas and other tumours.
There is an obvious need to study also the importance of many other genomic aberrations observed in tumours and their influence on the malignant potential of transformed cells.
Novel technologies including high-throughput genome sequencing (also called massive parallel sequencing) provide fast and complex view into the human genome. They are used to characterise genetic information of patient‘s normal and malignant cells to reveal mechanisms of cellular transformation.
