BACH1 and esophageal squamous cell carcinoma: The results of the Transwell assays indicated that overexpression of BACH1 notably promoted the migration and invasion of KYSE150 cells, and the opposite effects were observed in BACH1 knockdown KYSE30 and KYSE170 cells (Figure 3B), confirming that the effect of BACH1 on ESCC cells in vitro is consistent with promotion of invasion and metastasis.
