As has been reported by others, we confirmed elevation of expression of transcripts, such as 2′5′-oligoadenylate synthetase 1 (OAS1) and ISG12 also known as IFI27 (IFI27), by Taqman RT-PCR and normalization of sample cycle threshold to GAPDH in a second cohort of SLE patients as compared to healthy subjects (data not shown) [20], [21]. Here, GAPDH is linked to systemic lupus erythematosus.
