Description:
Deregulation of c-myc expression in association with chromosomal translocations occurs in over 95% of murine plasmacytomas, rat immunocytomas, and human Burkitt lymphomas. Infection with a murine retrovirus (J-3) containing an avian v-myc rapidly induced plasmacytomas in pristane-primed BALB/cAn mice. Only 17% of the induced plasmacytomas that were karyotyped showed the characteristic chromosomal translocations involving the c-myc locus. Instead, all of the translocation-negative tumors demonstrated characteristic J-3 virus integration sites that were actively transcribed. Thus, the high levels of v-myc expression have replaced the requirement for chromosomal translocation in plasmacytomagenesis and accelerated the process of transformation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Potter, M -- Mushinski, J F -- Mushinski, E B -- Brust, S -- Wax, J S -- Wiener, F -- Babonits, M -- Rapp, U R -- Morse, H C 3rd -- New York, N.Y. -- Science. 1987 Feb 13;235(4790):787-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3810165" target="_blank"〉PubMed〈/a〉
