UBTD1 is a Potential Prognostic Biomarker in Colorectal Cancer

Abstract Colorectal cancer (CRC) is a complex malignancy with poorly understood molecular mechanisms, necessitating the identification of genetic markers. Although Ubiquitin domain-containing protein 1 (UBTD1) has received significant attention in the study of human cancers, its specific role in CRC is yet to be fully clarified. This study sought to examine how UBTD1 expression was associated with various clinical and pathological characteristics of CRC, and to determine its prognostic significance and biological function, utilizing data from clinical samples and large-scale databases. Notably, UBTD1 expression was found to be upregulated in CRC, resulting in decreased survival rates and unfavorable clinical characteristics such as advanced T, N, and pathological stages. The findings of the multivariate Cox regression analysis illustrated that UBTD1 expression upregulation is a significant independent marker of unfavorable outcomes in CRC patients. An examination of the functional enrichment of UBTD1 and the genes it co-expresses indicated that it could serve as an oncogene by modulating the expression of genes implicated in crucial tumorigenesis pathways and functions. Additionally, immune cell infiltration analysis suggested a link between UBTD1 levels and various immune cells, particularly macrophages. In conclusion, the use of UBTD1 as a biomarker for both the prognosis and diagnosis of CRC has promising prospects for further investigation and therapeutic approaches.
