ACTL6A and esophageal squamous cell carcinoma: Further knocking down the ACTL6A gene in esophageal squamous cell carcinoma cells, it was found that ACTL6A could regulate the proliferation, migration, invasion, DNA damage repair, cell cycle, and apoptosis of esophageal squamous cell carcinoma cells, which further affected the radiosensitivity of esophageal squamous cell carcinoma cells.
