The present study explores the function of gene, a pivotal member of the Fanconi anaemia (FA) pathway crucial for preserving genomic stability and preventing cancer, particularly in the context of gastric cancer (GC). Using immunohistochemistry, quantitative real-time PCR, and western blot analysis, we evaluate FANCA mRNA and protein expressions in GC cell lines. The relationship between FANCA expression and clinicopathological characteristics is also explored. Various assays, including CCK8, colony formation, wound healing, and Transwell assays, are used to assess functional changes in cells associated with FANCA. Flow cytometry is utilized to evaluate alterations in the cell cycle resulted from knockdown and overexpression. Our findings show elevated FANCA expression in GC cell lines, with levels correlated with pathologic stage and lymphatic metastasis. knockdown impedes cell proliferation, migration, and invasion and induces G1/S phase cell cycle arrest. Conversely, overexpression stimulates cell proliferation, migration, and invasion. xenograft experiments confirm the promotional role of FANCA in GC tumor progression. Moreover, overexpression is associated with the activation of cell cycle. Collectively, our results suggest that FANCA drives malignant cell behaviors in GC through the cell cycle pathway, highlighting its potential as a therapeutic target for the treatment of GC.
本研究探讨了基因的功能,该基因是范可尼贫血(FA)途径的关键成员,对于维持基因组稳定性和预防癌症至关重要,特别是在胃癌(GC)中。我们使用免疫组织化学、定量实时 PCR 和 Western blot 分析评估了 GC 细胞系中 FANCA mRNA 和蛋白的表达。还探讨了 FANCA 表达与临床病理特征之间的关系。我们使用 CCK8、集落形成、划痕愈合和 Transwell 测定等各种测定来评估与 FANCA 相关的细胞功能变化。流式细胞术用于评估 敲低和过表达导致的细胞周期变化。我们的研究结果表明,GC 细胞系中 FANCA 的表达升高,其水平与病理分期和淋巴转移相关。 敲低抑制细胞增殖、迁移和侵袭,并诱导 G1/S 期细胞周期停滞。相反, 过表达刺激细胞增殖、迁移和侵袭。 异种移植实验证实了 FANCA 在 GC 肿瘤进展中的促进作用。此外, 过表达与细胞周期的激活有关。总之,我们的结果表明,FANCA 通过细胞周期途径驱动 GC 中的恶性细胞行为,提示其可能成为治疗 GC 的治疗靶点。
