DNMT3A and cancer: In contrast, the transcriptomes of Dnmt3a-cKO tumors were substantially more heterogeneous, suggesting that the loss of Dnmt3a could result in the deregulation of numerous different pathways in cancer cells, or that in the context of Dnmt3a loss, different cell of origins (i.e. basal IFE cells, hair follicle stem cells, or Lrig+ stem cells) might be more prone to generate more transcriptionally divergent tumors.
