Abstract
AbstractBackgroundPreviously, it was reported that the coiled‐coil domain containing 25 (CCDC25) plays a role in the formation of neutrophil extracellular traps (NETs). This study systematically analyzed the expression profiles of CCDC25 in 30 different types of cancer and one type of blood cancer, acute myeloid leukemia.MethodsThe GTEx and CCLE databases were used to evaluate the distribution of CCDC25 expression in both normal tissue and cancer cell lines. A comparison was performed between normal tissue and tumor tissue to analyze the differential expression of CCDC25. We assessed the impact of CCDC25 on the clinical outlook in the TCGA pan‐cancer data set by analyzing the Kaplan–Meier survival plot and conducting COX regression analysis. Moreover, the association between the expression levels of CCDC25 and the tumor microenvironment in multiple cancers was conducted. Additionally, the investigation also examined the link between CCDC25 and immune neoantigen, tumor mutational burden, microsatellite instability, mismatch repair genes (MMRs), HLA‐related genes, and DNA methyltransferase (DNMT).ResultsCCDC25 was expressed in nearly all of the 31 normal tissues while exhibiting a moderate to low level of expression in cancer cell lines. While abnormal expression was detected in the majority of malignancies, there was no link found between elevated CCDC25 levels and overall survival, disease‐free survival, recurrence‐free survival, and disease‐free interval in the TCGA comprehensive cancer data set. Nevertheless, the expression of CCDC25 exhibited a notable link with the infiltration levels of activated CD4 memory T cells, quiescent mast cells, dendritic cells in an activated state, T cells that assist in follicle development, M2 macrophages, and neutrophils in various tumors.ConclusionsIn most cancers, the results indicate that there is no link between CCDC25 and prognosis. However, CCDC25 can be targeted for therapeutic purposes concerning metastasis and immune infiltration.
