The present study examined the correlation between TRIM69 expression and colon adenocarcinoma (COAD) .  \nMethods mRNA sequencing data for COAD patients was extracted from The Cancer Genome Atlas to analyze correlations between TRIM69 expression and patients’ clinical features as well as survival. Potential associations with immune cells and chemosensitivity also were predicted using various algorithms in the TIMER, Limma, clusterProfiler, GeneMANIA, and Gene Set Cancer Analysis platforms. Subsequently, polymerase chain reaction analysis and immunohistochemical staining were used to detect TRIM69 expression in COAD tissue samples from real-world patients.  \nResults TRIM69 expression was lower in COAD tissues than in normal tissues and correlated with the pathologic stage and metastasis (M category) . Additionally, TRIM69 was found to be involved in several immune-related pathways, notably the NOD-like signaling pathway. These results suggest that high TRIM69 expression has the potential to enhance tumor sensitivity to 5-fluorouracil and programmed cell death protein 1 (PD-1) blockers. Conclusions From our findings that TRIM69 expression was significantly reduced in COAD compared with noncancer tissues and associated with pathologic stage and metastasis, we conclude that increasing TRIM69 expression and/or activity may help to improve therapeutic outcomes. Accordingly, TRIM69 represents a potentially valuable marker of metastasis and target for adjuvant therapy in COAD.  \nKeywords TRIM69, NOD-like signaling pathway, 5-Fluorouracil, PD-1 blockers, COAD  \n†Xiao-Jv Chi, Yi-Bei Song contributed equally to this work.  \n*Correspondence:  \nDong Lan [landong@stu.gxmu.edu.cn](landong@stu.gxmu.edu.cn)[ ](landong@stu.gxmu.edu.cn)Hui-Min He[hehuimin@sr.gxmu.edu.cn](hehuimin@sr.gxmu.edu.cn)  \n1Department of Clinical Laboratory, the First Affiliated Hospital of Guangxi Medical University, Key Laboratory of Clinical Laboratory Medicine of  \nGuangxi Department of Education, Guangxi Zhuang Autonomous Region, 6 Shuangyong Road, Nanning 530021, China  \n2Guangxi Medical University, Guangxi Zhuang Autonomous Region, 22 Shuangyong Road, Nanning 530021, China  \n3Department of Medical Oncology, the First Affiliated Hospital of Guangxi Medical University, Guangxi Zhuang Autonomous Region, 6 Shuangyong Road, Nanning 530021, China  \n© The Author(s) 2023.
