TUBB4B and neoplasm: As result, the taxane-resistant tumor showed elevated expression levels of TUBA1A (P = 0.0048), TUBA4B (P = 0.0335) and TUBB1 (P = 0.0309) and lower expression levels of TUBB2A (P = 0.0042), TUBB3 (P = 0.0006), TUBB4B (P = 0.0042), TUBB6 (P = 0.0024) and TUBCP3 (P = 0.0095) in comparison with the taxane-sensitive tumors (Figure 6B).
