Regulatory Action of Nerve Growth of Shark
Scientifics have confirmed antiangiogenic activity of cartilage extracts of bovine scapula by biological assays in vitro and in vivo. The AA of CT has been investigated in an in vitro model of labeled thymidine incorporation into human endothelial cells with addiction or not necrosis factor alpha tumoral. This study demonstrated that CT AA was in a fraction PM, and lower than 10 kda was also observed that thermos table. A CT extract is newly obtained was designated conventional designation its AA was shown in the model of the chorioallantoic membrane of chicken embryos, as well as inhibition of collagenase in vitro experiments. Canadian researchers have applied this work use in the therapy of psoriasis, which is an example of inflammatory an4qwd immune disease associated with vascular changes.
A potent inhibitor of angiogenesis has been purified blue shark cartilage and has been called U- 995.26 It consists of 2 single peptide with a molecular mass of 10 kDa and 14 respectively mind. In mice it was found that suppressing the growth of sarcoma -180 cells and metastasis of melanoma B16- F10 mouse in vivo. J. Lpez3 Menendez noted that the first Cuban clinical trial with the use of CT was observed in histological studies of biopsies and autopsies of patients included in the sample, a special type of tissue response attributed to CT, which consisted of a fibrotic tissue growth, which looked clear choke and islands of tumor cells. A modulation of this healing occupied by solid tumors and their metastases proposed to call it "cancer healing€ zone.
Finding angioinhibidores powerful agents that can be used in cancer therapy has continued with many other products. They are particularly prominent angiostatin, discovered in the urine of mice inoculated with cancerous tumors and endostatin purified from a line of tumor endothelial cells. Both products have been discovered and studied by the working group headed by J. Folk man, 29 and especially the latter, shown in bioassays in vitro and in vivo AA high. A disadvantage of some angioinhibidores emerged in the last 5 years is on its toxicity (thalidomide, tumor necrosis factor, Marimastat.
In the developing nervous system molecules of the extracellular matrix (MME) play an important regulatory role in processes such as cell migration, cell differentiation, neuritis outgrowth and establishment of synaptic connections? Receptors have been described for cell surface interactions with the MME: integrands, heterodinmicas transmembrane proteins and some proteoglycans. However, as asserted A.M. Clemens et al, 28 is more than the known structure and functions of the well-characterized glycoprotein lamina, fibronectin, and tenascin- C, which functions during development proteoglycans and neural regeneration. F. Lafont and others published a study of the effect of proteoglycans and glycosaminoglycans in the growth and morphology of neurons in tissue culture, to which proteoglycans glial cells or tumor cells from Engelbreth -Holm - Swarn is adicionaban, heparan sulfate kidney bovine, and chondroitin sulfate or dermatan sulfate CT bovine mucosa. Dermatan sulfate observed that selectively increased growth of dendrites, whereas others induce the appearance of a majority of cells with a long axon.
