Wound healing

A large number of studies have demonstrated the wound-healing effects of LLLT in vitro, in animal models, and in clinical practice. However, there are also differences in the study results, which are dose and wavelength dependent of LLLT. Evaluation of the wound healing process in experimental animals treated with low- level laser therapy in clinical and histopathology.

Abstract: Shrimp chitin and chitosan with improved characteristics were isolated from black tiger shrimp waste pretreated with 0.04 M Salicylic acid for ten hours. The pretreated shrimp shells could be efficiently demineralized and deproteinized at ambient temperature using 0.680 M HCl and 0.620 M NaOH, respectively. The duration of the treatments was 8 hours, the ash and protein residues in the final chitosan were about 0.48% and 0.51% respectively; the viscosity was 4800 cps; the solubility was up to 98%.

HR12 is anovel farnesyltransferase inhibitor (FTI).Wehave shown previously that HR12 induces phenotypic reversion of H-ras V12 -transformed Rat1 (Rat1/ras) fibroblasts. This reversion was characterized by formation of cell–cell con-tacts, focal adhesions and stress fibers. Here we show that HR12 inhibits anchorage independent and dependent growth of Rat1/ras cells. HR12 also suppresses motility and proliferation of Rat1/ras cells, in a wound healing assay. Rat1 fibroblasts transformed with myristoylated H-ras V12 (Rat1/myr-ras) were resistant to HR12....

The urokinase-type plasminogen activator (uPA) receptor (uPAR) has been implicated in signal transduction and biological processes including cancer metastasis, angiogenesis, cell migration, and wound healing. It is a specific cell surface receptor for its ligand uPA, which catalyzes the formation of plasmin from plasminogen, thereby activating the proteolytic cascade that contributes to the breakdown of extracellular matrix, a key step in cancer metastasis.

Fibroblasts play a critical role in chronic inflammation and wound healing. In this study, a fibroblast growth-stimulating factor was purified from the exudate of car-rageenan-induced inflammation in rats. The purified protein was a disulfide-linked homodimer. Amino acid sequence analysis of the peptides generated by cleavage with cyanogen bromide and proteinase V8 resulted in identification of the protein as S100A9. Recombinant S100A9 as well as its disulfide-linked homodimer stimu-lated the proliferation of fibroblasts at a similar con-centration of the purified protein. ...

Phenoloxidases occur in almost all organisms, being essentially involved in various processes such as the immune response, wound healing, pigmenta-tion and sclerotization in arthropods. Many hemocyanins are also capable of phenoloxidase activity after activation.

Vascular endothelial growth factor (VEGF) family members play impor-tant roles in embryonic development and angiogenesis during wound healing and in pathological conditions such as tumor formation. Parapox-viruses express a new member of the VEGF family which is a functional mitogen that specifically activates VEGF receptor (VEGFR)-2 but not VEGFR-1.

Integrin-mediated activation of Cdc42 is essential for cell polarization, whereas the integrin adaptor protein Cas is required for cell migration dur-ing wound healing. After phosphorylation on tyrosine residues, Cas recruits the adaptor proteins Crk and Nck to execute integrin-mediated signals.

Hepatocyte growth factor activator (HGFA) is a serine protease initially identified as a potent activator of hepatocyte growth factor⁄scatter factor. Hepatocyte growth factor⁄scatter factor is known to be critically involved in tissue morphogenesis, regeneration, and tumor progression, via its recep-tor, MET. In vivo, HGFA also activates macrophage-stimulating protein, which has roles in macrophage recruitment and inflammatory processes, cellular survival and wound healing through its receptor, RON....

Recent microarray studies comparing wounds and tumors have identified characteristic similarities in gene expression that may prove to be useful for assessing cancer prognosis and for choosing subsequent treatment.
