Cellular genetic therapy.

Cellular genetic therapy is the ultimate frontier for those pathologies that are consequent to a specific nonfunctional cellular type. A viable cure for there kinds of diseases is the replacement of sick cells with healthy ones, which can be obtained from the same patient or a different donor. In fact, structures can be corrected and strengthened with the introduction of undifferentiated cells within specific target tissues, where they will specialize into the desired cellular types. Furthermore, consequent to the recent results obtained with the transdifferentiation experiments, a process that allows the in vitro differentiation of embryonic and adult stem cells, it has also became clear that many advantages may be obtained from the use of stem cells to produce drugs, vaccines, and therapeutic molecules. Since stem cells can sustain lineage potentials, the capacity for differentiation, and better tolerance for the introduction of exogenous genes, they are also considered as feasible therapeutic vehicles for gene therapy. In fact, it is strongly believed that the combination of cellular genetic and gene therapy approaches will definitely allow the development of new therapeutic strategies as well as the production of totipotent cell lines to be used as experimental models for the cure of genetic disorders.

Identification of three novel cystic fibrosis mutations in a sample of Italian cystic fibrosis patients.

An analysis of 274 non-delta F508 Italian cystic fibrosis chromosomes was carried out to determine their molecular defect. In a first step, the delta F508 and 59 other mutations were detected by polyacrylamide gel electrophoresis, restriction digestion, and the amplification refractory mutation system (ARMS) technique. The molecular defects of the other chromosomes were screened for by denaturing gradient gel electrophoresis analysis of exons 3, 4, 7, 11, 12, 13, 14a, 17b, 19 and 20. Direct sequencing was carried out if necessary. This approach allowed us to identify 3 novel mutations, namely M348K, D614G and F693L.

[The correlation between the genotype and the clinical expression of cystic fibrosis].

The authors report a phenotype-genotype correlation in a population of patients from center and south Italy affected by cystic fibrosis (CF). Thirteen (21%) of patients with pancreatic insufficiency (PI) were homozygous for delta F508, seventeen (27%) were delta F508 heterozygous with an associated unknown allele. Two other described mutations (N1303K, G542X) were also found in a heterozygote status and associated with a severe clinical expression of disease.
