Relative Density Values of Bands; Tumor Compared to Mucosa

	Case 1	Case 2	Case 3
LAMP-1	1.41	1.27	1.17
18S rRNA	1.03	1.02	1.18
LAMP-2A	1.68	1.33	1.20
LAMP-2B	1.97	2.20	1.73
18S rRNA	1.43	1.26	1.22

All the values are relative and stand for the density of bands derived from tumor compared to mucosa samples. In each case and category, the density of normal samples was set at 1.00. Thus, the relative density value equals the density ratio (T/N). For instance, in case 1, although 18S rRNA from tumor showed 3% increase in density compared with its normal counterpart, LAMP-1 mRNA from tumor showed 41% increase in density compared with mRNA from normal. All the data are based on the results in Figure 2 ▶ .
