在世界范围内,胃癌是最致命的癌症之一。胃癌的表观遗传学改变在抑癌基因沉默中起重要作用。我们以前发现CXXC指蛋白4(CXXC 4)是一种新的胃癌抑癌基因。在这份报告中,我们证明了CXXC 4作为促凋亡因子抑制胃癌细胞的生长。这种抑制作用可以被称为Z-VAD-FMK的泛半胱天冬酶抑制剂逆转。然而,在其DNA结合结构域突变的CXXC 4不能诱导细胞凋亡。生长分化因子15(GDF 15)被认为是CXXC 4诱导细胞凋亡的潜在靶点之一。CXXC 4通过增强转录因子Sp1与GDF 15启动子的相互作用而激活GDF 15的转录。总之,核蛋白CXXC 4通过上调其新的潜在下游靶点GDF 15激活胃癌细胞凋亡。GDF 15可能成为临床治疗CXXC 4缺陷型胃癌的一个有前景的靶点。
Worldwide, gastric cancer is one of the most fatal cancers. Epigenetic alterations in gastric cancer play important roles in silencing of tumor suppressor genes. We previously found that CXXC finger protein 4 (CXXC4) was a novel tumor suppressor in gastric cancer. In this report, we demonstrated that CXXC4 inhibited growth of gastric cancer cells as a pro-apoptotic factor. This inhibition could be reversed by the pan-caspase inhibitor called Z-VAD-FMK. However, CXXC4 with mutations in its DNA binding domain failed to induce apoptosis. Growth differentiation factor 15 (GDF15) was identified as one of potential targets responsible for CXXC4-induced apoptosis. CXXC4 activated GDF15 transcription through enhancing the interaction of transcription factor Sp1 with GDF15 promoter. In summary, the nuclear protein CXXC4 activated apoptosis in gastric cancer through up-regulating its novel potential downstream target GDF15. GDF15 might be a promising target for clinical treatment of gastric cancer with CXXC4 deficiency.
