A similar trend was observed in the breast tissues (an ~16-fold increase in RBM6 expression in the chimeric negative tumour sample and an ~25-fold increase in the chimeric positive tumour sample), supporting an expression correlation between RBM6 expression and that of the RBM6-RBM5 chimeras, and demonstrating that the phenomenon was not tissue-specific. The gene discussed is RBM5; the disease is neoplasm.
