KLF4 Alleviates Hypertrophic Scar Fibrosis by Directly Activating BMP4 Transcription.

ABSTRACT: Background: Hypertrophic scars (HS) often occur after burns, surgery and extensive trauma. Krüppel-like factor 4 (KLF4) is a member of the Krüppel-like factor family, a group of conserved zinc finger transcription factors that regulate diverse cellular processes. KLF4 can participate in the regulation of fibrotic diseases in many organs, such as the lung, liver, and heart. However, the antifibrotic effect of KLF4 in skin HS remains elusive. Result: This study observed the inhibition of KLF4 on fibrosis in vivo and in vitro. Our results revealed that KLF4 expression was decreased in HS tissue and fibroblasts. The results of KLF4 transfection confirmed its ability to alleviate the transdifferentiation of fibroblasts into myofibroblasts both in vitro and
