| dc.description.abstract | Diferentes medicamentos que inducen la apoptosis de las células cancerosas a menudo no son selectivos y también afectan a las células normales. La inducción de apoptosis de un tipo celular específico en un organismo depende principalmente del reconocimiento de moléculas de superficie expresadas casi exclusivamente en este tipo de célula. Los receptores de células cancerosas porque están ausentes o son poco expresadas en células normales pero muy expresadas en algunos carcinomas, leucemias y linfomas. Se diseñó y sintetizó, 15 péptidos covalentemente al péptido del dominio de unión NEMO o al péptido mimético BCL-3 que inhibe la actividad de NF--FN1, AM1 y FN2-MP9-significativamente la viabilidad de las líneas celulares Hela y MCF7 pero no las células COS-7 y el péptido FN2 solo de la línea celular MCF7 como se determinó con ensayos de MTT y rojo neutro. La IC50 de AM2-MCF7. Los péptidos quiméricos, AM2-FN1 y FN2-MP9-Gp3, redujeron la viabilidad celular probablemente porque los péptidos NBD y BCL-3 impidieron la activación de la vía NF-desde el interior de la célula, considerando que los péptidos nativos no tenían este efecto. Los péptidos quiméricos, AM2-FN1 y FN2-MP9-Gp3 tienen potencial para ser utilizados como una alternativa quimiopreventiva y quimioterapéutica contra estos tipos de células tumorales. | |
| dc.description.abstractenglish | Many drugs that induces apoptosis of cancer cell often are not selective and also affect normal cells. The induction of apoptosis of a specific cell type in an organism mostly depends on the recognition of surface molecules almost exclusively expressed in this cell type. The integrin v6 and CD21 cell receptors could be used to establish a specific communication with cancer cells because they are absent or low expressed in normal cells but highly expressed in some carcinomas, leukemias and lymphomas. We designed and synthesized 15 chimeric peptides for targeting tumor cells expressing CD21 and the integrin v6, using the CD21 - or integrin v6 - binding peptides or two antimicrobial peptides covalently linked to either the NEMO binding domain peptide or the BCL-3 mimetic peptide that inhibits the NF-B activity. Peptides AM2-FN1, AM1 and FN2-MP9-Gp3, at 50 M significantly diminished the viability of Hela and MCF7 cell lines but not COS-7 cells and peptide FN2 only of MCF7 cell line as determined with neutral red and MTT assays. The IC50 of AM2-FN1 and AM1 was 16.82 and 27.17 M for the HeLa and 23.16 and 17.46 M for MCF7. Chimeric peptides, AM2-FN1 and FN2-MP9-Gp3, reduced the cell viability probably because the NBD and BCL-3 peptides prevented the NF-B pathway activation from inside the cell considering that native peptides did not have this effect. Chimeric peptides, AM2-FN1 and FN2-MP9-Gp3 have potential to be used as a chemopreventive and chemotherapeutic alternative against these types of tumor cells. | |
