Figure 1: Upregulation of Lcn2 in SM-injured patients. Gene expressions (a) were measured by semiquantitative RT-PCR. Lcn2 was upregulated in SM-injured patients (Lanes 3–12). Only 10 samples have been shown, compared to two normal samples (Lanes 1 and 2). M: 100-bp marker. (b) Ratio of NGAL/beta-actin has also been shown by a histogram.
