VEZT, a novel putative tumor suppressor, suppresses the growth and tumorigenicity of gastric cancer.

Vezatin (VEZT), an adherens junctions transmembrane protein, was identified as a putative tumor suppressor in our previous study. However, the role of VEZT in tumorigenesis remains elusive. We aimed to clarify its epigenetic regulation and biological functions in gastric cancer. In this study, we sh...
