The protein tyrosine kinase zeta-chain associated protein kinase (ZAP70), normally expressed in T cells and a subset of B cells, is solely expressed in poor prognosis chronic lymphocytic leukaemia and implicated in enhanced B cell receptor signalling. As a result, the expression of this protein provides an ideal prognostic marker for the disease. A previous study has shown differential CpG methylation of a 5' region of ZAP70 in leukaemic lymphoid cells, although no further epigenetic studies have been reported. Further investigation into the expression of ZAP70 may therefore provide targets for therapies.
蛋白酪氨酸激酶ζ链相关蛋白激酶(ZAP70)通常在T细胞和一部分B细胞中表达,而仅在预后不良的慢性淋巴细胞白血病中表达,并与增强的B细胞受体信号传导有关。因此,这种蛋白质的表达为该疾病提供了理想的预后标志物。先前的一项研究表明,白血病淋巴样细胞中ZAP70 5'区域存在差异CpG甲基化,尽管尚未有进一步的表观遗传学研究报道。因此,对ZAP70表达的进一步研究可能会为治疗提供靶点。
