Abstract:
The discovery that non-Hodgkin's lymphomas are monoclonal and that recurrent chromosomal translocations are involved in their pathogenesis has greatly revolutionised their diagnosis and improved our understanding of these diseases. In the last decades, many genes deregulated by such recurrent chromosomal translocations have been identified. However, we have also learned that these genetic alterations are apparently insufficient, in themselves, to cause neoplastic cell transformation and that more complex genetic events must be involved. This review examines the involved genes in chromosomal translocations and current evidence and postulated mechanisms for their role in the pathogenesis of non-Hodgkin's lymphomas.

When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
