The differential expression of long interspersed nuclear elements-1 as a marker for hypomethylation in Merkel cell carcinoma

Clin Exp Dermatol. 2022 Sep;47(9):1726-1728. doi: 10.1111/ced.15265. Epub 2022 Jul 12.

Abstract

The protein long interspersed nuclear elements-1 (LINE-1) serves as a useful surrogate marker of global methylation but little is known for Merkel cell carcinoma. LINE-1 expression was found only in Merkel cell polyomavirus (MCPyV)-positive Merkel cell carcinomas but not in MCPyV-negative Merkel cell carcinomas, suggesting that epigenetic dysregulation may be associated with MCPyV expression.
