Interestingly, high expression of YY1 was also associated with a longer DFS in prostate cancer (Seligson et al. 2005) and a better outcome in pancreatic cancer (Zhang et al. 2014), colon cancer (Chinnappan et al. 2009) and follicular lymphoma (Naidoo et al. 2011). This evidence concerns the gene YY1 and follicular lymphoma.
