Long and colleagues[24] measured the levels of HP-NAP-specific antibodies in various clinical groups of H. pylori-infected patients in China and reported a statistically significant step-wise elevation of serum antibodies from healthy subjects (sero-positivity: 27.7%, OD: 0.65±0.18), to chronic gastritis (sero-positivity: 85.7%, OD: 0.89±0.14), to gastric cancer (sero-positivity: 97.7%, OD: 1.01±0.24) patients. The gene discussed is CTNNBL1; the disease is chronic gastritis.
