GDF11 promotes wound healing in diabetic mice via stimulating HIF-1 ɑ-VEGF/SDF-1ɑ-mediated endothelial progenitor cell mobilization and neovascularization
Acta Pharmacol Sin. 2022 Nov 8. doi: 10.1038/s41401-022-01013-2. Online ahead of print.ABSTRACTNon-healing diabetic wounds (DW) are a serious clinical problem that remained poorly understood. We recently found that topical application of growth differentiation factor 11 (GDF11) accelerated skin wound healing in both Type 1 DM (T1DM) and genetically engineered Type 2 diabetic db/db (T2DM) mice. In the present study, we elucidated the cellular and molecular mechanisms underlying the action of GDF11 on healing of small skin wound. Single round-shape full-thickness wound of 5-mm diameter with muscle and bone exposed was made o...

Resveratrol Promotes Diabetic Wound Healing via SIRT1-FOXO1-c-Myc Signaling Pathway-Mediated Angiogenesis
Conclusion: Our findings indicate that the positive role of RES in diabetic wound healing via its SIRT1-dependent endothelial protection and pro-angiogenic effects involves the inhibition of FOXO1 and the de-repression of c-Myc expression. Introduction Diabetes mellitus is a metabolic disease with an increasing incidence worldwide (Zimmet et al., 2014). The disease often leads to the development of serious complications such as microangiopathy, mainly including retinopathy, nephropathy, neuropathy, and diabetic non-healing skin ulcers (Zheng et al., 2018). Diabetic non-healing skin ulcers such as foot ulcers are ca...

Systems Biology Approaches and Precision Oral Health: A Circadian Clock Perspective
Conclusion Most head and neck pathologies show a broad cellular heterogeneity making it difficult to achieve an accurate diagnosis and efficient treatment (Graf and Zavodszky, 2017; Lo Nigro et al., 2017). Single cell analysis of circadian omics (Lande-Diner et al., 2015; Abraham et al., 2018), may be a crucial tool needed in the future to fully understand the circadian control of head and neck diseases. It becomes more obvious that there is only a small genetic component but a largely unknown epigenetics and/or environmental component for most of the head and neck pathologies (Moosavi and Motevalizadeh Ardekani, 2016; He...
