1 · What the graph read from it

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.

2 · The registry

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 hypothesis that aberrant expression of homeobox (HOX) transcription factors contributes to oral cancer progression is gaining prominence. However, the mechanism of regulation involved in the clustered dysregulation of HOX clusters is not clearly known.

resultsOur findings revealed that HOXA and HOXB clusters showed significant locus-specific CpG methylation changes compared with the HOXC and HOXD clusters. The constitutively unmethylated regions identified in the HOXA1, HOXA11, HOXB5, HOXB6, HOXB9, HOXC5, HOXC10 and HOXC11 genes may be associated with open chromatin-mediated gene regulation. The methylation of CpG loci within the intron of HOXB9 may serve as a potential marker for distinguishing patients with premalignant and advanced oral tumors. HOXA5 and HOXC9 showed higher transcription factor-mediated interactions with neighboring HOX genes within and across the clusters. Additionally, HOXB9 and HOXC10 were predicted to directly regulate the G2-M checkpoint and hypoxia pathways. HOXA genes can be post-transcriptionally regulated through an antisense-mediated mechanism involving embedded HOX long noncoding RNAs (lncRNAs). Posterior HOX genes were more highly expressed than anterior HOX genes. The HOXC and HOXD cluster gene expression patterns were similar to those of the embedded lncRNAs. HOXA1, HOXC13 and HOXD10 were significantly correlated with the cancer hallmarks driving oral carcinogenesis.

conclusionThe functional consequence of HOX genes dysregulation was driven by diverse DNA and RNA epigenetic mechanisms affecting the transcriptional and post-transcriptional regulation contributing to the oral cancer progression.
