Figure 1. Expression of rpL3 and CBS in the lung tumor tissues.

(A) Representative western blotting of CBS and rpL3 protein expression in human lung cancer specimens paired with the corresponding normal tissues. N:non-tumor tissue. T:primary tumor tissue. Each number corresponds to a case number. β-actin was used as loading control. Quantification of signals is shown. **P < 0.01, *P < 0.05 vs. normal tissues set at 1. (B) qRT-PCR data showing the expression of CBS and rpL3 mRNAs in tumor tissues. **P < 0.01, *P < 0.05 vs. normal tissues set at 1. Results illustrated in Figs 1–7 are representative of three independently performed experiments; error bars represent the standard deviation.
