In-culture titration experiment for sRSE

ABSTRACT: In order to test the transcriptome-wide functionality of the identified sRSE instances, we performed an in vivo titration experiment in which synthetic RNA oligonucleotides harboring tandem sRSE1 repeats were used as intracellular decoys that would bind the putative trans factor, preventing it from targeting endogenous transcripts. Capped and poly-adenylated RNAs carrying tandem sRSE elements were transfected along with scrambled RNA molecules as control. 48 hours post-transfection, samples were subjected to transcriptome profiling to measure the regulatory consequences of the in-vivo titration of the sRSE-binding trans factor.

Aberrant regulation of RNA stability has an important role in many disease states. Deregulated post-transcriptional modulation, such as that governed by microRNAs targeting linear sequence elements in messenger RNAs, has been implicated in the progression of many cancer types. A defining feature of RNA is its ability to fold into structures. However, the roles of structural mRNA elements in cancer progression remain unexplored. Here we performed an unbiased search for post-transcriptional modula  ...[more]
