BRD2 and neoplasm: In the present work, we showed that tumor tissues have higher expressional variances than NAT samples, by obtaining NAT-DEGs and tumor-DEGs under two types of thresholds with a different strength of stringency, (i) FDR < 0.01 only, and (ii) both FDR < 0.01 and log2FC > 2, were applied (Fig. 2C).
