Objective To explore the relationship between expressions of TRFI protein during human multistage carcinogenesis of gastric cancer. Methods Expression of TRF1 protein was measured by Western blot ing to 10 normal gastric mueosa, 15 precancerous lesions, 20 gastric cancer and 5 lymph nodes with gastric cancer metastasis. Results The expression of TRF1 in gastric cancer tissues was significantly higher than that in normal gastric mucosa and precancerous lesions (P〈0.01). Low differentiated gastrie cancer had elevated TRF1 expression (P〈0.01)...
