A signature of correlated CDC20 and UBCH10 expression indicates poor prognosis in primary head and neck squamous cell carcinoma.
Article in BMC cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe orchestration of mitotic checkpoint execution depends on the enzymatic activity of the anaphase-promoting complex/cyclosome (APC/C), an E3 ubiquitin ligase. APC/C functions with the assistance of the adapter protein Cdc20 and the E2 ubiquitin-conjugating enzyme UbcH10 for orderly progression of mitosis. Reportedly, deregulated expression of either CDC20 or UBCH10 is associated with increased tumor aggressiveness in various human malignancies, including head and neck squamous cell carcinoma (HNSC). Previously, our laboratory reported that Cdc20 transcriptionally activates UBCH10 expression in cultured HNSC cells. This led us to investigate their correlated expression in primary HNSC malignancies in a prospective Eastern Indian study cohort and The Cancer Genome Atlas (TCGA) dataset.
methodsQuantitative PCR and immunohistochemistry analyses were performed to assess CDC20 and UBCH10 expression in primary HNSC patient samples of a prospective Eastern-Indian cohort. The RNA-sequencing data were retrieved from TCGA-head and neck squamous cell carcinoma (HNSC) cohort. Additionally, FISH assay was carried out to investigate cellular ploidy status in HNSC tumor and adjacent normal samples, as well as in cultured HNSC cells and validated in silico in TCGA cohorts. Assays to evaluate proliferation, migration and invasion of HNSC cells were conducted under the influence of correlated expression of CDC20 and UBCH10. Kaplan–Meier analyses was performed to determine the impact of survival outcome under the influence of correlated CDC20-UBCH10 expression.
resultsThe initial results revealed correlated overexpression of both genes in a significant number of primary HNSC samples from the prospective cohort. Concordantly, gene expression data from the TCGA-HNSC cohort revealed a similar correlation. In addition, HNSC-affected individuals with this correlated overexpression showed an increased level of cellular aneuploidy. More importantly, Kaplan‒Meier analyses revealed that patients harboring this correlated expression signature had the poorest survival outcome. Findings of exacerbation in proliferation, migration and invasion properties of cultured HNSC cells, under the influence of concerted overexpression of CDC20-UBCH10, further corroborated our findings. Further investigations revealed that this expression signature occurs in several other malignancies of solid tissues and negatively influences their survival outcomes.
conclusionsTogether, these findings delineate the correlation of CDC20-UBCH10 overexpression with survival outcomes in patients with primary HNSC and other solid tumors and suggest the potential of this expression signature for prognostication.
