Project description:The purpose of this study is to investigate whether LED light at different wavelength can improve wound healing in both diabetic fibroblast. In this study, both diabetic and normal fibroblast cell lines were cultured and created some artificial wounds with pipette tips. After LED irradiation and microarray analysis, we found that GPCR Class A, a rhodopsin-like-structure gene, was significantly up regulated in all treated groups. Besides, for normal cell treated groups, the expression of other genes relevant to defense response to virus became strongly higher. However, in diabetic cells, genes relating to acute inflammatory response and mitotic cell cycle were highly expressed. Researchers also found that diabetic cells significantly respond to wound healing better than normal cells because inflammatory response, cell migration, cell proliferation, cell adhesion, and regulation of mitosis pathways can be instantly activated by red and green LED light according to gene expression profiles. Diabetic fibroblast cells were irradiated with different wavelength (red/green/blue) LED color and compare their gene expression with the control groups.

Abstract:
In this paper, a novel mathematical model of wound healing in both normal and
diabetic cases is presented, focusing upon the effects of adding two currently
available commercial engineered skin substitute therapies to the wound
(Apligraf) and Dermagraft). Our work extends a previously developed model, which
considers inflammatory and repair macrophage dynamics in normal and diabetic
wound healing. Here, we extend the model to include equations for
platelet-derived growth factor concentration, fibroblast density, collagen
density, and hyaluronan concentration. This enables us to examine the variation
of these components in both normal and diabetic wound healing cases, and to
model the treatment protocols of these therapies. Within the context of our
model, we find that the key component to successful healing in diabetic wounds
is hyaluronan and that the therapies work by increasing the amount of hyaluronan
available in the wound environment. The time-to-healing results correlate with
those observed in clinical trials and the model goes some way to establishing an
understanding of why diabetic wounds do not heal, and how these treatments
affect the diabetic wound environment to promote wound closure.

Project description:MicroRNAs are powerful gene expression regulators, but their corneal repertoire and potential changes in corneal diseases remain unknown. Our purpose was to identify miRNAs altered in the human diabetic cornea by microarray analysis, and to examine their effects on wound healing in cultured telomerase-immortalized human corneal epithelial cells (HCEC) in vitro. Using microarrays, 29 miRNAs were identified as differentially expressed in diabetic samples. Two miRNA candidates showing the highest fold increased in expression in the diabetic cornea were confirmed by Q-PCR and further characterized. HCEC transfection with h-miR-146a or h-miR-424 significantly retarded wound closure, but their respective antagomirs significantly enhanced wound healing vs. controls. Cells treated with h-miR-146a or h-miR-424 had decreased p-p38 and p-EGFR staining, but these increased over control levels close to the wound edge upon antagomir treatment. In conclusion, several miRNAs with increased expression in human diabetic central corneas were found. Two such miRNAs inhibited cultured corneal epithelial cell wound healing. Dysregulation of miRNA expression in human diabetic cornea may be an important mediator of abnormal wound healing. Total RNA was extracted from age-matched human autopsy normal (n=6) and diabetic (n=6) central corneas, Flash Tag end-labeled, and hybridized to Affymetrix® GeneChip® miRNA Arrays. Select miRNAs associated with diabetic cornea were validated by quantitative RT-PCR (Q-PCR) and by in situ hybridization (ISH) in independent samples.

Project description:Wound healing is a multi-step process to rapidly restore barrier function. This process is often impaired in diabetic patients resulting in chronic wounds and amputation. We previously found that paradoxical activation of the mitogen-activated protein kinase (MAPK) pathway via topical administration of the BRAF inhibitor vemurafenib accelerates wound healing by activating keratinocyte proliferation and reepithelialization pathways in healthy mice. Herein, we investigated whether this wound healing acceleration also occurs in impaired diabetic wounds and found that topical vemurafenib not only improves wound healing in a murine diabetic wound model, but unexpectedly promotes hair follicle regeneration. Neogenic hair follicles expressing Sox-9, CD34 and K15 were found in wounds of diabetic and non-diabetic mice, and their formation can be prevented by blocking downstream MEK signaling. Thus, topically applied BRAF inhibitors may accelerate wound healing, and promote the restoration of improved skin architecture in both normal and impaired wounds.

Project description:Chronic and non-healing skin wound is one of grievous complications of diabetes. In this study, we demonstrated a gas (carbon monoxide)-releasing hyaluronic acid hydrogel (i.e. COHAG) in promoting diabetic wound healing. Our results show that the COHAG significantly accelerated the healing process in diabtic rat full-thickness skin defect model, as compared with hydrogel without gas-releasing molecule and untreated group. Single-cell analysis of regenerating skin samples revealed that Cxcl14-overexpressing (Cxcl14+) fibroblast with progenitor properties are abundantly accumulated at the wound site after COHAG therapy.
