Targeting TEAD would be a potential strategy for scarless wound repair: A preliminary study.

Despite of decades of efforts, novel approaches are still limited to attenuate or prevent skin scarring. A previous report published in Science demonstrated that inhibition of YAP promotes scarless wound repair by regeneration. Due to the difficult drugability of targeting YAP, we speculated that inhibition of TEAD, a partner molecule of YAP, might exist similar therapeutic potential.

Protopanaxadiol synergizes with glucocorticoids to enhance the therapeutic effect in adriamycin-induced nephrotic syndrome.
