PITX1 and neoplasm: Indeed, observing over half a million cells (520,847 cells, of these, were 279,410 in tumor regions and 241,437 in non-tumor regions), we found higher averaged telomere-staining intensity indicating longer telomeres in samples with high PITX1 expression compared to samples with PITX1 status negative (p-value < 0.001, Mann–Whitney U Test, Figure 2D).
