OAS1 and systemic lupus erythematosus: According to correlation analysis, expression of STAT1, OAS1, OASL, and PML on BRCA tumor tissue were positively correlated with immune cell markers from both innate immunity and adaptive immunity (Fig. 5E), while expression of STAT1, OAS1, OASL, and PML in whole blood of SLE was positively correlated with most of immune markers in innate immunity (Fig. 5F).
