This study identified differential expression of Coiled-Coil Domain-Containing (CCDC) proteins in colorectal cancer (CRC) and their association with patient survival. High expression of CCDC154 was found to be associated with poor survival and correlated with low infiltration of CD8+ T cells and high infiltration of neutrophils, suggesting its role in promoting tumor growth and metastasis. CCDC154 was also found to interact with Minichromosome Maintenance Complex Component 2 (MCM2) protein and promote malignant phenotype via MCM2.
Coiled-Coil Domain-Containing (CCDC) is a large class of structural proteins containing left-handed supercoiled structure. The clinical value and the functional implication of CCDC in colorectal cancer (CRC) remain unknown. Based on the genetic, transcriptional, and clinical data from The Cancer Genome Atlas, five of thirty-six CCDC proteins were differentially expressed in the CRC and associated with the survival of patients with CRC. A CCDC-score model was established to evaluate the prognosis of patients. The potential function of Coiled-Coil Domain-Containing 154 (CCDC154) was investigated using bioinformatical methods, which unveiled that high expression of CCDC154 indicates poor survival for patients with CRC and correlates with low infiltration of CD8+ T cells and high infiltration of neutrophils, indicating that CCDC154 enhances tumor growth and metastasis. CCDC154 in-teracts with Minichromosome Maintenance Complex Component 2 (MCM2) protein and promotes malignant phenotype via MCM2. We validated the expression level and survival prediction value of CCDC154 in clinical samples, and analyzed its co-expression of MCM2, Ki-67 and p53. This work discloses the role of CCDC in clinical setting and CCDC154 functions in CRC.
