Bladder cancer(BC) is one of the most prevalent cancers in the urinary tract, with high recurrence and fatality rates. Research indicates that go-ichi-ni-san complex subunit 1 (GINS1) crucially influences cancer progression by regulating DNA replication through cell cycle modulation. Thus, suppressing the active proliferation of cells in tumor tissues may require silencing GINS1. However, the consequences of GINS1 in bladder cancer aren't to be determined. In this paper, we examine the role and mechanism of GINS1 in the development of bladder cancer. GINS1 expression levels and prognostic relevance in bladder cancer were validated using Western blotting, immunohistochemistry, and Kaplan-Meier survival analysis. The influence of GINS1 on bladder cancer was investigated using a variety of approaches, including cell transfection, cell counts, transwell migrations, colony formation, and flow cytometry. Immunohistochemistry studies demonstrate that GINS1 expression is increased in bladder cancer tissues. GINS1 silencing resulted in an arrest of the cell cycle at the phase of G0/G1, which inhibited BC cell growth both in vitro and in vivo. GINS1 knockdown also hindered the AKT/mTOR pathway. Furthermore, increased GINS1 expression affects the cell cycle and stimulates the AKT/mTOR pathway, allowing BC to develop more quickly. Consequently, GINS1 occurs as a latent therapeutic target, particularly for individuals with BC.
膀胱癌(BC)是最常见的尿路肿瘤之一,具有高复发率和死亡率。研究表明,GINS1 通过调节细胞周期来调控 DNA 复制,对癌症的进展起着至关重要的作用。因此,抑制肿瘤组织中细胞的活跃增殖可能需要沉默 GINS1。然而,GINS1 在膀胱癌中的作用尚未确定。在本文中,我们研究了 GINS1 在膀胱癌发展中的作用和机制。通过 Western blot、免疫组化和 Kaplan-Meier 生存分析验证了 GINS1 在膀胱癌中的表达水平和预后相关性。通过细胞转染、细胞计数、transwell 迁移、集落形成和流式细胞术等多种方法研究了 GINS1 对膀胱癌的影响。免疫组化研究表明,GINS1 在膀胱癌组织中表达增加。GINS1 沉默导致细胞周期在 G0/G1 期停滞,从而抑制了 BC 细胞的体外和体内生长。GINS1 敲低也抑制了 AKT/mTOR 通路。此外,增加的 GINS1 表达会影响细胞周期并刺激 AKT/mTOR 通路,从而使 BC 更快地发展。因此,GINS1 是一个潜在的治疗靶点,特别是对于膀胱癌患者。
