The expression levels of five type I IFIGs (LY6E, OAS3, IFIT4, OAS1 and OAS2) were significantly higher in the SLE group than in the healthy and non-SLE controls.
Statistically significant differences in genotype, allele, and haplotype frequencies for 3 OAS2 single nucleotide polymorphisms (rs1293762, rs15895, and rs1732778) and 2 OAS3 single nucleotide polymorphisms (rs2285932 and rs2072136) were detected between patients with central nervous system disease and both those with fever and/or meningitis and the control group.
Differential upregulation of human 2'5'OAS genes on systemic sclerosis: Detection of increased basal levels of OASL and OAS2 genes through a qPCR based assay.
Despite differences in the specific residues targeted for methylation/demethylation, OAS2 expression was upregulated in all conditions and correlations between methylation and expression were seen in psoriasis and tongue SCC.
Two sub-pathways (intracellular antiviral molecules and extracellular pattern recognition) and four genes in these sub-pathways (TLR1, TLR6, OAS1, and OAS2) were nominally associated with advanced prostate cancer risk and harbor several SNPs nominally associated with advanced prostate cancer risk.

Gene expression of PKR and OAS2 was also significantly decreased in skin biopsies from ADEH(+) subjects compared with patients with atopic dermatitis without a history of eczema herpeticum and nonatopic subjects.
Depression and fatigue during chronic IFN-α administration were associated with alterations in the expression (OAS2) and transcriptional control (CREB/ATF) of genes linked to behavioral disorders including CFS and major depression, further supporting an immune contribution to these diseases.

Invasion potential was >2-fold greater in GSN-overexpressing LoVo cells than in control cells (p<0.001-0.005), whereas OAS2-overexpressing RKO cells showed reduced invasion (p<0.001-0.005).
Although all three enzymatically active OAS proteins in humans--OAS1, OAS2, and OAS3--synthesize 2-5A upon binding dsRNA, it is unclear which are responsible for RNase L activation during viral infection.
Collectively these results show that OAS2 leads to impairment in CD3-ζ chain expression, so offering an explanation that might be applicable to the CD3-ζ chain deficiency observed in cancer and diverse disease conditions.
