ITLN1 and cancer: After analyzing RNA-sequencing data generated from normal mesothelial cells isolated from the omental adipose tissue of healthy women, and from ascites-derived mesothelial cells isolated from HGSC patients8, we found that ITLN1 is the most downregulated gene in cancer-associated mesothelial cells compared with normal mesothelial cells (Fig. 1b, Supplementary Table 1).
