Interestingly, we found that human HDAC1, but not human HDAC2, mRNA expression is increased in some Burkitt’s lymphoma (BL) and diffuse large B cell lymphoma (DLBCL) cancer cell lines and human lymphoma samples, when compared to other cancer cell lines or other human cancer samples, respectively (Supplementary Figure 3). The gene discussed is HDAC1; the disease is cancer.
