Clinical Significance:

The c-Myc protein is a 62 kDa transcription factor that is encoded by the c-Myc gene on human chromosome 8q24. c-Myc is commonly activated in a variety of tumor cells and plays an important role in cellular proliferation, differentiation, apoptosis and cell cycle progression. Studies have shown that c-Myc is essential for vasculogenesis and angiogenesis in tumor development, which distributes blood throughout the cells. The c-myc oncogene (p62 c-myc) is involved in the control of normal cellular proliferation and differentiation, and the deregulated expression of c-Myc induces apoptosis in different cell types.  Amplification of the c-Myc gene has been found in several types of human tumors including lung, breast and colon carcinomas. Translocation of the c-myc locus on chromosome 8 to the immunoglobulin loci on chromosome 14 (heavy chain); 2 (delta light chain); or 22 (light chain) is described in Burkitts lymphoma and other B-cell lymphoproliferative conditions.
