MicroRNA in keloid pathogenesis

Hajime Shimizu, Ramin Ghazizadeh, Mohammad Ghazizadeh

Abstract


Keloid is a fibro-proliferative lesion that develops as a result of abnormal wound healing in susceptible individuals. Many factors such as skin tension, wound infection, racial difference and genetic predisposition have been implicated in the etiology of keloid. MicroRNAs are highly conserved noncoding small RNA sequences and are key posttranscriptional gene regulators that contribute to the maintenance of differentiated cell phenotype. In this review, we outline the results of the studies on the expression of various miroRNAs in keloid as well as their role in pathogenesis of this lesion.


Keywords
