Loss of Methylation Modification Marks the Presence of Psoriasis

Abstract

The reversibility of epigenetic alterations makes them the attractive targets for therapeutic discovery; however, their potential remains untapped owing to a lack of mechanistic understanding, particularly for inflammatory skin disorders. Here, Li and colleagues begin to fill these gaps by identifying the loss of the DNA hydroxymethylation mark 5-hmC in psoriasis and presenting compelling evidence for its potential contribution to disease manifestations.
