Abstract
Depending on extent and depth, burn injuries and resulting scars may be challenging and expensive to treat and above all heavily impact the patients' lives. This systematic review represents the current state of knowledge on molecular pathways activated during burn wound healing. All currently known molecular information about gene expression and molecular interactions in mammals has been summarized. An ample interaction of regenerative cytokines, growth factors, ECM-regenerative molecules and proinflammatory immune response became apparent. We identified three molecules to be most often involved in the pathways: TGFB1, ACTA1 and COL1A1. Yet, other factors including FLII, AKT1 and miR-145 were shown to play pivotal roles in burn wound healing as well. This systematic review helps to explain the fundamental molecular proceedings participating in burn wound healing. A number of new molecular interactions and functional connections were identified yielding intriguing new research targets. An interactive version of the first network about molecular pathways and interactions during burn wound healing is provided in the online edition and on WikiPathways.

J Surg Res 2020; 260:155-162. [PMID: 33340869 DOI: 10.1016/j.jss.2020.11.068] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2020] [Revised: 10/02/2020] [Accepted: 11/15/2020] [Indexed: 01/19/2023]
Abstract
BACKGROUND Burn progression is a phenomenon that remains poorly characterized. The mechanisms of burn conversion are not completely understood, and consequently, both predictive diagnostic tools and interventions are limited. The rat comb burn model is a commonly used approach to study horizontal burn conversion. However, there is significant variability in how the model is performed. Skin contact duration, comb device heating method, comb heating duration, amount of pressure applied, the weight of the comb, and associated depth of burn are all variables that are heterogeneous in studies utilizing the model. MATERIALS AND METHODS Here, contact duration was examined to determine the impact the duration of burn delivery has on the conversion of interspaces in this model. Data from multiple experiments consisting of 10, 15, 20, 30, 40, and 45 s comb burns were compiled and assessed. Burns were made using combs heated in a 100°C dry bath and then monitored for 2 d. Interspace viability was assessed by digital and laser doppler imaging and biopsy procurement. RESULTS Laser Doppler Imaging and viable interspace measurements showed that as burn duration increased, the percentage of the viable interspace and interspace perfusion decreased. Additionally, a contact time of 30 s or greater was required to result in 100% interspace conversion. CONCLUSIONS These results demonstrate a need to better characterize and potentially standardize the rat comb burn model to reduce variation and maintain it as a valuable tool for controlled studies of the pathophysiology of burn wound progression.

Abstract
Bearing in mind the doctrine of tumor angiogenesis hypothesized by Folkman
several decades ago, the fundamental strategy for alleviating numerous cancer
indications may be the strengthening application of notable antiangiogenic
therapies to inhibit metastasis-related tumor growth. Under physiological
conditions, vascular sprouting is a relatively infrequent event unless when
specifically stimulated by pathogenic factors that contribute to the
accumulation of angiogenic activators such as the vascular endothelial growth
factor (VEGF) family and basic fibroblast growth factor (bFGF). Since VEGFs have
been identified as the principal cytokine to initiate angiogenesis in tumor
growth, synthetic VEGF-targeting medicines containing bevacizumab and sorafenib
have been extensively used, but prominent side effects have concomitantly
emerged. Traditional Chinese medicines (TCM)–derived agents with distinctive
safety profiles have shown their multitarget curative potential by impairing
angiogenic stimulatory signaling pathways directly or eliciting synergistically
therapeutic effects with anti-angiogenic drugs mainly targeting VEGF-dependent
pathways. This review aims to summarize (a) the up-to-date
understanding of the role of VEGF/VEGFR in correlation with proangiogenic
mechanisms in various tissues and cells; (b) the elaboration of
antitumor angiogenesis mechanisms of 4 representative TCMs, including
Salvia miltiorrhiza, Curcuma longa, ginsenosides, and
Scutellaria baicalensis; and (c)
circumstantial clarification of TCM-driven therapeutic actions of suppressing
tumor angiogenesis by targeting VEGF/VEGFRs pathway in recent years, based on
network pharmacology.

Notch Regulates Macrophage-Mediated Inflammation in Diabetic Wound Healing. Front Immunol 2017; 8:635. [PMID: 28620387 PMCID: PMC5451506 DOI: 10.3389/fimmu.2017.00635] [Citation(s) in RCA: 60] [Impact Index Per Article: 8.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2017] [Accepted: 05/12/2017] [Indexed: 12/22/2022] Open
Abstract
Macrophages are essential immune cells necessary for regulated inflammation during wound healing. Recent studies have identified that Notch plays a role in macrophage-mediated inflammation. Thus, we investigated the role of Notch signaling on wound macrophage phenotype and function during normal and diabetic wound healing. We found that Notch receptor and ligand expression are dynamic in wound macrophages during normal healing. Mice with a myeloid-specific Notch signaling defect (DNMAMLfloxedLyz2Cre+) demonstrated delayed early healing (days 1–3) and wound macrophages had decreased inflammatory gene expression. In our physiologic murine model of type 2 diabetes (T2D), Notch receptor expression was significantly increased in wound macrophages on day 6, following the initial inflammatory phase of wound healing, corresponding to increased inflammatory cytokine expression. This increase in Notch1 and Notch2 was also observed in human monocytes from patients with T2D. Further, in prediabetic mice with a genetic Notch signaling defect (DNMAMLfloxedLyz2Cre+ on a high-fat diet), improved wound healing was seen at late time points (days 6–7). These findings suggest that Notch is critical for the early inflammatory phase of wound healing and directs production of macrophage-dependent inflammatory mediators. These results identify that canonical Notch signaling is important in directing macrophage function in wound repair and define a translational target for the treatment of non-healing diabetic wounds.
