Project description:Urinary bladder wound healing is today pooorly chracterized. MicroRNAs are small non-coding RNA molecules with regulatory functions. In this study we aimed at identifying microRNAs expressed during bladder wound healing. We performed Affymetrix microRNA profiling of the rodent urinary bladder during healing of a surgically created wound.

Project description:Impaired re-epithelialization is a hallmark of non-healing, chronic skin wounds. These represent major causes of patient morbidity, particularly amongst ever-increasing ageing and diabetic populations, posing significant challenges to healthcare providers worldwide. Despite many treatment options being available, these often offer limited benefits to healing outcomes. We address the need for more efficacious treatments through evaluation of novel epoxy-tigliane compounds as chronic wound pharmaceuticals, based on their effectiveness in promoting keratinocyte healing responses and re-epithelialization in vivo. Here, we identify that prototype epoxy-tigliane (EBC-46) and analogue (EBC-211), accelerate G1/S and S/G2 cell cycle transitions and proliferation in a normal human keratinocyte cell line of skin origin (HaCaTs). EBC-46 and EBC-211 further induce HaCaT migration/wound repopulation, even with mitomycin C treatment, suggesting epoxy-tiglianes can promote migration/repopulation independently of proliferation. Epoxy-tiglianes modulate keratin, DNA synthesis/replication, cell cycle/proliferation, motility/migration, differentiation, proteinase; and cytokine/chemokine gene expression, to facilitate enhanced responses. Although epoxy-tiglianes down-regulate cytokine/chemokine agonists of keratinocyte proliferation/migration, we demonstrate that enhanced HaCaT responses are mediated through protein kinase C (PKC) phosphorylation and abrogated by inhibition of PKC activation with bisindolylmaleimide-1 (BIM-1). By identifying how epoxy-tiglianes stimulate keratinocyte healing responses, we highlight their potential as novel therapeutics for impaired re-epithelialization associated with non-healing, chronic wounds.

Project description:Diabetic foot ulcers (DFU) are one of the major complications in type II diabetes patients and can result in amputation and morbidity. Although multiple approaches are used clinically to help wound closure, many patients still lack adequate treatment. Here we show that IL-20 subfamily cytokines are upregulated during normal wound healing. While there is a redundant role for each individual cytokine in this subfamily in wound healing, mice deficient in IL-22R, the common receptor chain for IL-20, IL-22, and IL-24, display a significant delay in wound healing. Furthermore, IL-20, IL-22 and IL-24 are all able to promote wound healing in type II diabetic db/db mice. When compared to other growth factors such as VEGF and PDGF that accelerate wound healing in this model, IL-22 uniquely induced genes involved in reepithelialization, tissue remodeling and innate host defense mechanisms from wounded skin. Interestingly, IL-22 treatment showed superior efficacy compared to PDGF or VEGF in an infectious diabetic wound model. Taken together, our data suggest that IL-20 subfamily cytokines, particularly IL-20, IL-22, and IL-24, might provide therapeutic benefit for patients with DFU.

Project description:The cornea, transparent and outermost structure of camera-type eyes, is prone to environmental challenges, but has remarkable wound healing capabilities which enables to preserve vision. The manner in which cell plasticity impacts wound healing remains to be determined. In this study, we report rapid wound closure after zebrafish corneal epithelium abrasion. Furthermore, by investigating the cellular and molecular events taking place during corneal epithelial closure, we show the induction of a bilateral response to a unilateral wound. Our transcriptomic results, together with our TGF-beta receptor inhibition experiments, demonstrate conclusively the crucial role of TGF-beta signaling in corneal wound healing. Finally, our results on Pax6 expression and bilateral wound healing, demonstrate the decisive impact of epithelial cell plasticity on the pace of healing. Altogether, our study describes terminally differentiated cell competencies in the healing of an injured cornea. These findings will enhance the translation of research on cell plasticity to organ regeneration.

Project description:Wound healing is essential to repair the skin after injury. In the epidermis, distinct stem cells (SCs) populations contribute to wound healing. However, how SCs balance proliferation, differentiation and migration to repair a wound remains poorly understood. Here we show the cellular and molecular mechanisms that regulate wound healing in mouse tail epidermis. Using a combination of proliferation kinetics experiments and molecular profiling, we identify the gene signatures associated with proliferation, differentiation and migration in different regions surrounding the wound. Functional experiments show that SC proliferation, migration and differentiation can be uncoupled during wound healing. Lineage tracing and quantitative clonal analysis reveal that, following wounding, progenitors divide more rapidly, but conserve their homeostatic mode of division, leading to their rapid depletion whereas SCs become active, giving rise to new progenitors that expand and repair the wound. These results have important implications for tissue regeneration, acute and chronic wound disorders.

Project description:Adalimumab, but neither etanercept nor certolizumab-pegol, has been reported to induce a wound healing profile in the circulation of patients with hidradenitis suppurativa (HS), a chronic inflammatory skin disease. However, the role of tumor necrosis factor alpha (TNF) inhibitors in cutaneous wound healing in vivo is still unclear. To examine and compare the efficacy of various TNF inhibitors in cutaneous wound healing in vivo, a human TNF knock-in Leprdb/db mouse model was established to model the impaired cutaneous wound healing as seen in HS. The vehicle group exhibited severe impairments in cutaneous wound healing. In contrast, adalimumab significantly accelerated healing, confirmed by both histologic assessment and a unique healing transcriptional profile. Moreover, adalimumab and infliximab showed similar levels of efficacy, but golimumab was less effective, along with etanercept and certolizumab-pegol. In line with histologic assessments, proteomics analyses from healing wounds exposed to various TNF inhibitors revealed distinct and differential wound healing signatures that may underlie the differential efficacy of these inhibitors in accelerating cutaneous wound healing. Taken together, these data revealed that TNF inhibitors exhibited differential levels of efficacy in accelerating cutaneous wound healing in the impaired wound healing model in vivo likely through distinct mechanisms of action related to the structure of the biologic or its ability to bind TNF.
