Do you think this miRNA is real?
Comments
miR-263b was reported independently in references [1] and [2]. Computational prediction followed by northern blotting confirmed that the strand containing the predicted miR is predominantly expressed [1]. Reference [2] confirmed the ends of the excised miRNA by cloning.
