Colorectal cancer (CRC) is a malignant tumor with a high incidence and mortality worldwide. Currently, the underlying molecular mechanisms of CRC are still unclear. Zinc finger protein 3 (ZNF3) is a zinc-finger transcription factor that has been reported as a candidate for breast cancer prognosis, suggesting its involvement in the regulation of tumorigenesis. However, the association between ZNF3 and CRC remains unknown. To investigate the role of ZNF3 in CRC, we first analyze the correlation between ZNF3 expression and CRC, and the results demonstrate that ZNF3 is highly expressed in CRC tissue and cells, which is associated with the age of CRC patients. studies show that ZNF3 overexpression promotes CRC cell migration. Compared to control cells, knockdown of markedly suppresses CRC cell proliferation, migration and invasion and promotes G0/G1 phase cell cycle arrest. The expressions of the EMT-related markers TWIST and MMP1 are significantly decreased when is silenced. Additionally, overexpression of MMP1 and TWIST exacerbates CRC cell proliferation, accelerates the S phase cell cycle in -knockdown SW480 cells, and increases cell migration and invasion through Transwell chambers. These data suggest that ZNF3 is involved in cellular proliferation, migration and invasion by regulating MMP1 and TWIST in CRC cells.
结直肠癌(CRC)是一种在全球范围内发病率和死亡率都很高的恶性肿瘤。目前,CRC 的潜在分子机制仍不清楚。锌指蛋白 3(ZNF3)是一种锌指转录因子,已被报道为乳腺癌预后的候选物,提示其参与肿瘤发生的调节。然而,ZNF3 与 CRC 之间的关联尚不清楚。为了研究 ZNF3 在 CRC 中的作用,我们首先分析了 ZNF3 表达与 CRC 之间的相关性,结果表明 ZNF3 在 CRC 组织和细胞中高度表达,与 CRC 患者的年龄有关。研究表明,ZNF3 过表达促进 CRC 细胞迁移。与对照细胞相比,沉默 显著抑制 CRC 细胞的增殖、迁移和侵袭,并促进 G0/G1 期细胞周期停滞。当沉默 时,EMT 相关标志物 TWIST 和 MMP1 的表达显著降低。此外,过表达 MMP1 和 TWIST 通过 Transwell 室增加 CRC 细胞的增殖、加速 -knockdown SW480 细胞的 S 期细胞周期,并增加细胞迁移和侵袭。这些数据表明,ZNF3 通过调节 CRC 细胞中的 MMP1 和 TWIST 参与细胞增殖、迁移和侵袭。
