Abstract
Background: Head and neck squamous cell carcinomas (HNSCs) are a diverse collection of tumors that originate in the oral cavity, pharynx, and larynx and pose a severe threat to human health, contributing to a fast-rising burden of cancer morbidity and mortality. The search for prognostic biomarkers of HNSC has been a hot topic. Spindle and kinetochore-associated (SKA) complex, including three members SKA1/2/3, which stabilize the spindle microtubules at the kinetosite during mitosis metaphase, has been demonstrated to be associated with poor prognosis of different cancers. The function of SKA1/2/3 in HNSC remains to be investigated. We used a vast variety of public datasets and web-based technologies to investigate SKA complex expression and its link to patient prognosis, and discovered multiple pathways by which the SKA complex is regulated in HNSC.
Methods: The Cancer Genome Atlas (TCGA) database was used to determine SKA1/2/3 expression level in HNSC. SKA1/2/3-related proteins level and immune cells infiltration level were identified. Metascape was used for Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis. GSE31056 from Gene Expression Omnibus (GEO) database was used as an external dataset for data validation. A nomogram containing SKA1/2/3 for the prognosis of HNSC patients was established.
Results: SKA1/2/3 were highly expressed in HNSC. High expression of SKA2 was significantly related to the poor overall survival (OS) and poor disease-free survival (DFS) of HNSC patients. SKA1/2/3 and the related proteins were enriched in cell division, chromosome segregation, and mitotic cell cycle. SKA1/2/3 expression was obviously positively correlated to several immune cells' infiltration. The expression values of SKA1/2/3 were higher in tumors than in healthy tissues in GSE31056.
Conclusions: SKA1/2/3 were shown to be related to the prognosis and immune cell infiltration of HNSC, which could be used as biological markers and therapeutic targets for HNSC.
期刊介绍：
Translational Cancer Research (Transl Cancer Res TCR; Print ISSN: 2218-676X; Online ISSN 2219-6803; http://tcr.amegroups.com/) is an Open Access, peer-reviewed journal, indexed in Science Citation Index Expanded (SCIE). TCR publishes laboratory studies of novel therapeutic interventions as well as clinical trials which evaluate new treatment paradigms for cancer; results of novel research investigations which bridge the laboratory and clinical settings including risk assessment, cellular and molecular characterization, prevention, detection, diagnosis and treatment of human cancers with the overall goal of improving the clinical care of cancer patients. The focus of TCR is original, peer-reviewed, science-based research that successfully advances clinical medicine toward the goal of improving patients'' quality of life. The editors and an international advisory group of scientists and clinician-scientists as well as other experts will hold TCR articles to the high-quality standards. We accept Original Articles as well as Review Articles, Editorials and Brief Articles.
