GAPDH and lung adenocarcinoma: Figure S1B shows that overexpression of FLJ10540 was observable in our lung patient samples, with 15 out of 16 lung patient tumors (94%) showing a higher signal after normalization to GAPDH for equal template loading. The average expression level of FLJ10540 in lung adenocarcinomas was 8 fold higher than that in adjacent non-tumor lung tissue samples, as analyzed by boxplot (Figure 1A, right panel).
