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

The tumor microenvironment plays a pivotal role in cancer development. We recently reported that in oral squamous cell carcinoma (OSCC), adipocyte enhancer-binding protein 1 (AEBP1) is abundantly expressed in cancer-associated fibroblasts (CAFs), leading to CAF activation and inhibition of CD8 + T cell infiltration. In the present study, we investigated whether AEBP1 contributes to the destruction and atrophy of muscle tissues in OSCC. By analyzing human skeletal muscle myoblasts (HSMMs), we found that AEBP1 is downregulated during muscle cell differentiation. Transcriptome analysis revealed that AEBP1 knockdown significantly upregulates myogenesis-related genes in HSMMs, and qRT-PCR and western blot analyses confirmed the induction of muscle-related genes, including MYOG, in HSMMs after AEBP1 knockdown. Conversely, ectopic expression of AEBP1 strongly suppressed myogenesis-related genes in HSMMs. Notably, indirect co-culture of HSMMs with OSCC cells led to AEBP1 upregulation and robust suppression of muscle-related genes in HSMMs. Treatment with TGF-β1 also upregulated AEBP1 and suppressed expression of muscle-related genes in HSMMs. Our findings suggest that AEBP1 is a negative regulator of skeletal muscle cell differentiation and that OSCC cells inhibit muscle cell differentiation, at least in part, by inducing AEBP1.
