| Summary |
Purpose: To evaluate whether the single nucleotide polimorphsim rs41291957, located in the pri-miR-143/145, influences the primary RNA secondary structure.
Methods: In vitro transcription and folding for the pri-miR-143/145 carrying the WT allele (G) or the mutated one (A) was carried out. The RNAs were then subjected to RNAseI treatement for 30 minutes and RNA seq performed on the digested nucleic acids.
Results: Using an optimized data analysis workflow for small RNAs, we mapped the sequence reads on the human pri-miR-143/145 carrying the G- or A-allele. We observed an increase of small reads (<60bps) for the A-allele and a different profile of read enrichement between the digested G- and A-allele RNA, indicating the difference in secondary structure.
