HDAC6 and diffuse large B-cell lymphoma: Other works have shown that HDAC6 inhibition can inhibit MET/PI3K/AKT signaling by up-regulating micro(mi)RNA-27b (Liu et al., 2018) or down-regulating HR23B (Liu et al., 2018), thereby inhibiting the viability and proliferation of DLBCL cells and promoting apoptosis (Figure 1E).
