Core Tip

Core tip: Methyl-methanesulfonate sensitivity 19 (MMS19) was first identified as a DNA repair protein, and recently as a part of cytoplasmic Fe-S assembly machinery that produce proteins involved in maintenance of genomic stability, such as DNA polymerase, DNA repair proteins, and DNA nuclease/helicase. However, the clinical significance of MMS19 protein expression in esophageal cancer has not been reported. This study shows that MMS19 is abnormally expressed in esophageal cancer, and the elevated cytoplasmic MMS19 expression is associated with lymph node and distant metastases, and response to chemoradiotherapy in esophageal squamous cell carcinoma.
