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...

Blockage of MyD88 in cardiomyocytes alleviates cardiac inflammation and cardiomyopathy in experimental diabetic mice
In this study, we first found that MyD88 expression was increased in cardiomyocytes of diabetic mouse hearts. In cultured cardiomyocytes, MyD88 inhibition either by siRNA or by small-molecular inhibitor LM8 markedly blocked TLR4-MyD88 complex formation, reduced pro-inflammatory mitogen-activated protein kinases/nuclear factor-κB (MAPKs/NF-κB) cascade activation and decreased pro-inflammatory cytokine expression under high glucose condition. Moreover, pharmacologic inhibition of MyD88 by LM8 showed significantly anti-inflammatory, anti-hypertrophic and anti-fibrotic effects in the hearts of both type 1 and type 2 diabetic...

Transforming growth factor- β1/Thrombospondin-1/CD47 axis mediates dysfunction in CD34 < sup > + < /sup > cells derived from diabetic older adults
This study tested the hypothesis that transforming growth factor- β1 (TGF-β1) is upregulated in diabetic CD34+ cells and impairs NO generation via thrombospondin-1 (TSP-1)/CD47/NO pathway. CD34+ cells from nondiabetic (ND) (n=58) or diabetic older adults (DB) (both type 1 and type 2) (n=62) were isolated from peripheral blood. TGF-β1 was silenced by using an antisense delivered as phosphorodiamidate morpholino oligomer (PMO-TGF-β1). Migration and proliferation in response to stromal-derived factor-1α (SDF-1α) were evaluated. NO generation and eNOS phosphorylation were determined by flow cytometry. CD34+ cells from ol...

Pharmacological inhibition of MyD88 suppresses inflammation in tubular epithelial cells and prevents diabetic nephropathy in experimental mice
Acta Pharmacol Sin. 2021 Sep 22. doi: 10.1038/s41401-021-00766-6. Online ahead of print.ABSTRACTEmerging evidence shows that chronic inflammation mediated by toll-like receptors (TLRs) contributes to diabetic nephropathy. Myeloid differentiation primary-response protein-88 (MyD88) is an essential adapter protein of all TLRs except TLR3 in innate immunity. It is unclear whether MyD88 could be a therapeutic target for diabetic nephropathy. Here, we used a new small-molecule MyD88 inhibitor, LM8, to examine the pharmacological inhibition of MyD88 in protecting kidneys from inflammatory injury in diabetes. We showed that MyD88...

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...

Glycyrrhizic acid increases glucagon like peptide-1 secretion via TGR5 activation in type 1-like diabetic rats.
Abstract Glycyrrhizic acid (GA) is belonged to triterpenoid saponin that is contained in the root of licorice and is known to affect metabolic regulation. Recently, glucagon like peptide-1 (GLP-1) has widely been applied in diabetes therapeutics. However, the role of GLP-1 in GA-induced anti-diabetic effects is still unknown. Therefore, we are interested in understanding the association of GLP-1 with GA-induced effects. In type 1-like diabetic rats induced by streptozotocin (STZ-treated rats), GA increased the level of plasma GLP-1, which was blocked by triamterene at a dose sufficient to inhibit Takeda G-protein-...

Upregulated serum sclerostin level in the T2DM patients with femur fracture inhibits the expression of bone formation/remodeling-associated biomarkers via antagonizing Wnt signaling.
CONCLUSIONS: Our study demonstrated that the upregulated serum sclerostin level in the T2DM patients with fracture inhibited the expression of the bone formation/remodeling-associated biomarkers via antagonizing Wnt signaling. It suggests that sclerostin might be an effective target for T2DM-associated bone fracture and delayed fracture healing. PMID: 28239825 [PubMed - in process]
