MRPS23 and atrial fibrillation: We collected the blood of patients with comorbidities of the two diseases and found that CASP8 expression in the AS + AF group was not significantly different from that in the control group (Figure 11E), but MRPS23 was significantly upregulated in the comorbidities group (Figure 11F), indicating that MRPS23 may be the most potential predictor of comorbidities.
