Homeobox A5 () has been identified as a tumor suppressor gene in breast cancers, but its role in oral squamous cell carcinoma (OSCC) has not been confirmed. The Illumina GoldenGate Assay for methylation identified that DNA methylation patterns differ between tumorous and normal tissues in the oral cavity and that is one of the genes that are hypermethylated in oral tumor tissues. The present study obtained more‑complete information on the methylation status of by using the Illumina Infinium MethylationEPIC BeadChip and bisulfite sequencing assays.

CD8 T cell spatial distribution in the context of tumor microenvironment (TME) dictates the immunophenotypes of tumors, comprised of immune-infiltrated, immune-excluded and immune-desert, discriminating "hot" from "cold" tumors. The infiltration of cytotoxic CD8 T cells is associated with favorable therapeutic response. Hitherto, the immunophenotypes of esophageal squamous cell carcinoma (ESCC) have not yet been comprehensively delineated.

Department of Laboratory Medicine, Shanghai Chest Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, People's Republic of China.

Metastasis is the leading cause of mortality from esophageal squamous cell carcinoma (ESCC). By the time of diagnosis, most ESCC tumors have already invaded the lymph nodes or distant organs; however, it has been challenging to identify and confirm genes with a crucial role in ESCC metastasis. The microfibrillar-associated protein 2 (MFAP2) is upregulated in human ESCC, and its expression level was positively associated with poor overall and disease-free survival.
