Besides, their associated genes were found, including HDAC9, CMPK2, MINDY4B, ATOH8, SOX7, LOC100859478, etc. Among them, five lncRNAs (LOC107052235, ATOH8, LOC101751658, SOX7, and LOC100859478) were hypomethylated and low expressed in ALV-J induced tumor livers, while the other lncRNAs like HDAC9, CMPK2, MINDY4B, etc., was hypermethylated and highly expressed in ALV-J induced tumor livers. Here, CMPK2 is linked to neoplasm.
