The association of LEF1 with ID1 expression in human ESCC specimen. a Representative images of LEF1 and ID1 staining by IHC in ESCC TMA sections of 31 patients (scale bar, 50 μm). The immunostaining levels of LEF1 and ID1 were also scored from 0 to 3. b Correlation of expression levels of LEF1 and ID1 is shown. c, d Western blotting analysis (c) and correlation analyses (d) of LEF1 expression with expression of ID1 in six freshly collected human ESCC samples
