TTLL6 and carcinoma of esophagus: To elucidate the mechanisms by which TTLL6 promotes the sensitivity of the esophageal carcinoma cells to drug treatment, we examined global gene expression profiles in EC109/CDDP cells which were infected with Lv-TTLL6 or Lv-GFP as well as transfected with siRNA against TTLL6 or control siRNA by cDNA microarray.
