Abstract

Introduccion del gen NeuroD1 humano en células epiteliales pancreáticas no endocrinas (NEPEC) para producir células productoras de insulina in vitro. Se transfectaron NEPEC positivas citoqueratina (CK19) con plásmidos que codifican al gen NeuroD1 humano bajo un promotor CK19 humano. La caracterizacion posterior a la induccion permitio determinar que las NEPEC transfectadas c/plásmidos con NeuroD1 y promotor CK19 tres veces por día denominadas NEPEC+ND expresaban fuertemente NeuroD1 y ARNm de insulina. La relacion de células positivas para NeuroD1 a insulina humana en NEPEC+ND era significativamente mayor que en las NEPEC. Lo niveles de insulina y péptido C humanos en medios de cultivo en NEPEC+ND eran significativamente mayor que en NEPEC. Los hallazgos demuestran que el NeuroD1 humano bajo el control del promotor CK19 induce la diferenciacion de células NEPEC positivas para CK19 en células productoras de insulina. Reivindicacion 1: Un método de tratamiento de diabetes en un mamífero que lo necesita, caracterizado porque comprende administrar una cantidad terapéuticamente eficaz de un ácido nucleico aislado que incluye una secuencia que codifica un gen NeuroD1 en una o más células epiteliales pancreáticas no endocrinas de dicho mamífero y expresar una proteína NeuroD1 en la célula, en donde dicha proteína NeuroD1 comprende la secuencia de aminoácidos indicada en las SEQ ID N°: 10 o 12, para tratar así la diabetes del mamífero.
