The experiments on mice had been authorized by the ethics committee at Nanfang hospital.Correlation of CTSL Expression with Overall SurvivalThe median follow-up time for general survival was 78 months for all sufferers. The 2-year and 5-year general prices for all individuals have been 65.6 and 33.six , respectively. Among these sufferers, the general survival of your individuals with low CTSL expression (5-year all round price, 41.four ) was significantly greater than the higher CTSL expression group (5-year all round price, 22.7 ) (P = 0.032, Figure 3).
