Formatted abstract
It is well established that transcription and alternative splicing events are functionally coupled during gene expression. Here, we report that protein arginine N-methyltransferase 6 (PRMT6) may play a key role in this coupling process by functioning as a transcriptional coactivator that can also regulate alternative splicing. PRMT6 coactivates the progesterone, glucocorticoid and oestrogen receptors in luciferase reporter assays in a hormone-dependent manner. In addition, small interfering RNA (siRNA) oligonucleotide duplex knockdown of PRMT6 disrupts oestrogen-stimulated transcription of endogenous GREB1 and progesterone receptor in MCF-7 breast cancer cells, demonstrating the importance of PRMT6 in hormone-dependent transcription. In contrast, the regulation of alternative splicing by PRMT6 is hormone independent. siRNA knockdown of PRMT6 increases the exon inclusion: skipping ratio of alternatively spliced exons in endogenous vascular endothelial growth factor and spleen tyrosine kinase RNA transcripts in both the presence and absence of oestrogen. These results demonstrate that PRMT6 has a dual role in regulating gene expression and that these two functions can occur independently of each other.
