TNF and pancreatic neoplasm: Although the highest similarly was observed for A549 cell-based studies (positions 1 and 2), besides we identified similarities to the transcriptional profiles of (i) other human epithelial NSCLC cell lines, such as NCI-H358 and HCC827, upon treatment with TGFbeta (position 3 and 10, respectively); (ii) human pancreatic cancer cell line PANC-1 upon treatment with TGFbeta (position 7); and of (iii) human retinal pigment epithelial cell line ARPE-19 upon treatment with TNFalpha and TGFbeta2 (position 8, 9).
