As shown in Table 3, High serum level of EMMPRIN was observed in poorly differentiated lung cancer patients (105.33±11.46 pg/mL) and moderately differentiated lung cancer patients (106.24±14.92 pg/mL), as compared with well differentiated lung cancer patients (96.28±16.27 pg/mL) (p=0.029). The gene discussed is BSG; the disease is lung carcinoma.
