Introduction

We desired to access the polyadenylation status of the miR34a asRNA transcript.



Methods



Cell culture and PCR All cell lines were cultured at 5% CO2 and 37° C with HEK293T cells cultured in DMEM high glucose (Hyclone). All growth mediums were supplemented with 10% heat-inactivated FBS and 50 μg/ml of streptomycin and 50 μg/ml of penicillin. RNA was extracted using the RNeasy mini kit (Qiagen) and subsequently treated with DNase (Ambion Turbo DNA-free, Life Technologies). 500ng RNA was used for cDNA synthesis using MuMLV (Life Technologies) and a 1:1 mix of oligo(dT) and random nanomers. PCR was then performed and the results analyzed on a 2% agarose gel.

Polyadenylation status of spliced and unspliced miR34a asRNA in HEK293T cells.



Conclusions

Results indicate that miR34a asRNA is polyadenylated.
