Abstract:
Malignant tumors of childhood represent a rather heterogeneous group of neoplasms originating from virtually any anatomical structure. Despite major improvements in the clinical management including timely diagnosis, advanced supportive care and refined multimodality treatment, prognosis remains grim for certain risk groups. Aberrant epigenetic regulation, i.e. changes in gene transcription not due to DNA sequence alterations, is now increasingly recognized as a fundamental process in malignant transformation, tumor progression and drug resistance. The molecular mechanisms involve aberrant activity of enzymes controlling the packaging and transcriptional regulation of the genome. Two major protein families are involved in this process, DNA methyltransferases and histone deacetylases. With the availability of small molecule inhibitors targeting the aberrant epigenetic machinery in cancer cells, these compounds are evaluated in several clinical trials.
