The tumour suppressor role of BCL2L11 is also supported by its deletion in 40% of mantle cell lymphomas (Tagawa et al., 2005), silencing through CpG promoter methylation in natural killer cell lymphomas (Küçük et al., 2015) and its targeting by the oncogenic miR-32 and miR17-92 microRNAs (Ventura et al., 2008; Koralov et al., 2008; Ambs et al., 2008). The gene discussed is BCL2L11; the disease is neoplasm.
