In case of LTR9NS we detected the normal Nras mRNA in which the LTR was excised as part of intron 1 as well as two types of LTR initiated mRNAs lacking exon 1 of Nras. The two LTR-initiated mRNAs corresponded to those observed in the original tumor 9 harboring a provirus at this position, indicating that the inserted solo-LTR functions similarly to the inserted provirus. This evidence concerns the gene NRAS and neoplasm.
