naturally occurring antisense RNAs in eukaryotes

[Dr. G. Koraimann]

Hi!
Does anybody out there know of a well documented and published example of a 
naturally occurring antisense RNA in eukaryotic organisms ? If so, please tell 
me about it, I would greatly appreciate that information.
Many thanks
