title: The 5' noncoding region of the human leukemia-associated oncogene BCR/ABL is a potent inhibitor of in vitro translation.
abstract: The mRNA encoding the chimeric BCR/ABL oncogene, which is transcribed from the Philadelphia chromosome in human chronic myelogenous leukemia, has a 5' noncoding sequence greater than 500 bases in length which is highly GC rich and contains a short open reading frame. This untranslated sequence has a dramatic inhibitory effect upon translational efficiency in vitro. However, when BCR/ABL message is expressed in certain cell types such as the NIH 3T3 cell line, the 5' noncoding region has little inhibitory effect on translational efficiency.
