NKILA and non-Hodgkin lymphoma: Thirdly, to our knowledge, this is the first study that reported that promoter DNA methylation mediated the reversible silencing of NKILA in NHL, which is evidenced by an inverse correlation between the NKILA methylation and its expression in NHL cell lines, and the re-expression of NKILA upon demethylation treatment in cell lines with a complete methylation of NKILA.
