Abstract

Colorectal cancer is one of the most common cancers worldwide with a high incidence rate. Therefore, the molecular basis of colorectal tumorigenesis and evolution must be clarified. Structure-specific recognition protein 1 (SSRP1) is involved in transcriptional regulation, DNA damage repair, and cell cycle regulation and has been confirmed to be highly expressed in various tumor tissues, including colorectal cancer. However, the role of SSRP1 in the development of colorectal cancer remains unclear. Therefore, this study explored the role of SSRP1 in the occurrence and development of colorectal cancer. Using bioinformatics databases, including samples from the Cancer Genome Atlas (TCGA), we confirmed high expression in human colorectal adenocarcinoma tissues. We demonstrated that knockdown via small interfering RNA significantly inhibited the proliferation of colorectal cancer cells and promoted apoptosis through the AKT signaling pathway, suppressing the invasion and migration of colorectal cancer cells and . In conclusion, this study demonstrated that silencing influenced the proliferation and apoptosis of colorectal cancer cells via the AKT signaling pathway.

摘要

结直肠癌是全球最常见的癌症之一,发病率较高。因此,必须阐明结直肠肿瘤发生和演进的分子基础。结构特异性识别蛋白 1(SSRP1)参与转录调控、DNA 损伤修复和细胞周期调控,已被证实在包括结直肠癌在内的各种肿瘤组织中高表达。然而,SSRP1 在结直肠癌发展中的作用尚不清楚。因此,本研究探讨了 SSRP1 在结直肠癌发生发展中的作用。我们使用包括癌症基因组图谱(TCGA)在内的生物信息学数据库,证实了人结直肠腺癌组织中 SSRP1 的高表达。我们通过小干扰 RNA 敲低实验证实,SSRP1 沉默通过 AKT 信号通路显著抑制结直肠癌细胞的增殖,促进细胞凋亡,抑制结直肠癌细胞的侵袭和迁移。综上所述,本研究表明,SSRP1 沉默通过 AKT 信号通路影响结直肠癌细胞的增殖和凋亡。
