Abstract
Disclosed herein are methods and compositions for detecting differential expression of certain miRNAs in cancer cells or their surrounding normal tissues in the tumor microenvironment. The disclosure describes an automated, highly sensitive and specific method for detection of any cellular RNA molecule, including microRNA, messenger RNA and non-coding RNA. The technology includes probe design as well as probe use in an automated fashion for detection of RNA molecules in formalin-fixed paraffin-embedded tissue (FFPET) samples.
