Cancer-causing bacterium targets tumor-suppressor protein

Researchers have discovered that Helicobacter pylori's CagA protein disables the tumor suppressor protein RUNX3 in host cells, leading to gastric cancer. The interaction between CagA and RUNX3 causes degradation of the protein via ubiquitination, promoting aberrant cell growth and cancer development.
