DESCRIPTION<\/b><\/td>\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Hepatocarcinoma represents one of the principal causes of death through cancer worldwide, with an approximate figure of one million deaths per year and a 5 year survival rate of below 5%. The results of the various forms of tratements available are unsatisfactory on a long term period that\u2019s why a new therapeutic strategy is becoming necessary. The possibility of the treatment of this cancer, a disease defined by defective genes, through introduction of a gene which targets this modification, lead to an enormous interest for the gene therapy of the cancer. p53 is a tumor suppressive gene with an important role in the regulation of cell cycle and it is considered that loss of the function of \u201cwild type\u201d of p53 is a promoter of carcinogenesis. The in vitro and in vivo studies had demonstrated that reintroduction and expression of \u201cwild type\u201d p53 in the tumoral cells with mutation of p53 lead to decreased growth of the tumor and induction of apoptosis. One of the limitations of this gene therapy represents the finding of an adequate vector to introduce the \u201cwild type\u201d p53 in the tumoral cells. Restoring the normal activity of antioncogenic p53 causes tumor regression. The reactivation of p53 can lead to apoptosis or can cause reduction in the proliferation respectively senescence of the cell.
\nThe NANOGEN project proposes increased efficiency in the treatment of hepatocarcinoma with the help of gene therapy through internalization of p53 in the tumoral hepatic cells by using a nanoparticle vector with an increased affinity to these tumoral cells.<\/td>\n<\/tr>\n
