Subcellular distribution of mRNA and eRNA expression. Human monocytic THP-1 cells were stimulated with LPS for 2 h or 6 h prior to RNA extraction from either total cells or the nuclear and cytoplasm fractions. qRT-PCR was then used to analyse the expression and distribution, relative to a total cell fraction, of (a) IL6 and SOD2 mRNA and (b) SLC30A4-eRNA, SOCS3-eRNA, AZIN1-eRNA, TNFSF8-eRNA, MARCKS-eRNA and ACSL1-eRNA by qRT-PCR. Data is the mean ± S.E.M. of 3 independent experiments.
