BRD2 and neoplasm: Patients presenting with a greater depth of tumor invasion (T4) showed a significantly higher expression of the miRNA within the NAT tissue (median -∆CT = − 17.00), compared to the T3 stage (median -∆CT = − 19.14) and the early stages (T1 & T2) (median -∆CT = − 21.92) (p = 0.0009) (Fig. 6B).
