Skin wound healing is one of the major prevalent medical problems in the worldwide. Wound healing involves multi-process synergy and re-epithelialization is an essential part of wound healing. Histone H3K36 tri-methylase Setd2 has been extensively studied in different biological processes and diseases. However, the function of Setd2 in the wound healing remains unclear. To elucidate the biological role of Setd2 in the skin wound healing, conditional gene targeting was employed to establish epidermis-specific Setd2-deficient mice. We found that Setd2 deficiency resulted in accelerated re-epithelialization during cutaneous wound healing by promoting keratinocytes proliferation and migration. Furthermore, we demonstrated that loss of Setd2 activated the AKT/mTOR pathway, and pharmacological inhibitions of AKT and mTOR with MK2206 and rapamycin delayed wound closure, respectively. In conclusion, our results reveal the essential role of Setd2 in skin wound healing that is Setd2 loss promotes cutaneous wound healing via activation of AKT/mTOR signaling.
