El objetivo de la terapia génica para el tratamiento del cáncer es eliminar las células tumorales preservando el tejido normal. Diversas estrategias para llevar acabo este objetivo han demostrado resultados promisorios en el laboratorio, incluyendo moléculas que pueden tener blancos específicamente predeterminados en secuencias en el ADN y el ARNm; estas secuencias proporcionan un medio para modular la función de genes endógenos. Diferentes tipos de moléculas: inductores de hélices triples, oligodeoxinucleótidos antisentido, ribozimas, ARN de interferencia, aptámeros y señuelos son revisados en este documento.
The objective of gene therapy for the treatment of cancer is to kill tumor cells but preserve normal tissue. A variety of strategies to achieve these aims have demonstrated promising results in the laboratory, including molecules that can specifically target pre-determined sequences in the DNA or RNAm; that sequences provide a means to modulate endogenous gene function. The different types of molecules: triplex forming molecules, antisense oligodeoxynucleotides, ribozymes, RNA interference, aptamers and decoys, are reviewed in this paper.
