AEBP1 is a negative regulator of skeletal muscle cell differentiation in oral squamous cell carcinoma.

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 A
