GALNS and neoplasm: These six genes include ROCK1, which is known to be associated with EGFR regulation, as well as CKAP2L, TPR, ALDH4A1, CLCA2, and GALNS. We have found that the six log2-fold changes of the microarray expression levels and those of the qPCR expression levels are highly correlated with a Pearson correlation coefficient of 0.99 (p-value = 0.00002), suggesting that the set of 1140 genes might contain some further putative target genes of EGFR isoforms II-IV in tumor cells.
