To evaluate whether DLC-1 could be a therapeutic target for non-Hodgkin lymphoma (NHL), we examined the expressions of DLC-1 in Burkitt's lymphoma (BL) cell lines and tested the effects of DLC-1 on cellular growth and migration in BL cells.
Transcriptional silencing and methylation of DLC1 was detected in most Hodgkin (HL) and non-Hodgkin lymphoma (NHL) cell lines, including 4/6 Hodgkin, 4/4 nasal NK/T-cell, 6/6 Burkitt and 5/5 diffuse large B-cell lymphoma cell lines.
Although some genes such as DLC-1 and PCDHGB7 were methylated in the vast majority of NHLs, others were differentially methylated in specific subtypes.
