Statistical analysis showed no differences in the expression of the genes between the individuals with lung cancer at three time points and the control group (TIMP1 (before surgery p = 0.1083; 100 days after surgery p = 0.8224; one year after surgery p = 0.8457), MMP2 (before surgery p = 0.938; 100 days after surgery p = 0.4236; one year after surgery p = 0.0527) and MMP9 (before surgery p = 0.217; 100 days after surgery p = 0.5146; one year after surgery p = 0.278)). The gene discussed is TIMP1; the disease is lung carcinoma.
