锌指血淋巴限制性转录因子Ikaros在一些人类白血病中发生突变。此外，伊卡洛斯DNA结合域的遗传缺失与小鼠侵袭性T淋巴细胞白血病有关。因此，Ikaros对生长调节基因的转录调控可能是某些白血病发生的重要潜在原因。最近，我们收集了新的数据表明，Ikaros转录调控VIP-PACAP受体1(VPAC-1)的表达，该受体已被证明传递抗增殖信号。因此，我们建议研究Ikaros对T淋巴细胞中VPAC-1的转录调控。

英文摘要

The zinc-finger hemolymphopoietic-restricted transcription factor, Ikaros, is mutated in some human leukemias. Moreover, genetic deletions of the Ikaros DNA-binding domain were associated with an aggressive T lymphocyte leukemia in mice. Thus, the transcriptional regulation of growth-modulating genes by Ikaros may be an important underlying cause for the development of certain leukemias. Recently, we have collected novel data suggesting that Ikaros transcriptionally regulates the expression of VIP-PACAP receptor 1 (VPAC-1), which has been demonstrated to transmit anti-proliferative signals. Therefore, we propose to investigate the transcriptional regulation of VPAC-1 by Ikaros in T lymphocytes.
