Abstract
Un método para determinar una respuesta de un sujeto que padece sepsis o shock séptico al tratamiento con un inhibidor de la farnesil transferasa, que comprende las etapas: (i) medir un nivel de al menos un marcador seleccionado entre el grupo que consiste en proteínas identificadas en la Tabla 4 y en los transcriptos de los genes identificados en las Tablas 2 y 3 en una muestra de sangre sin tratar obtenida del sujeto antes del tratamiento con el inhibidor de la farnesil transferasa, y (ii) medir un nivel del marcador en una muestra de sangre tratada obtenida del sujeto al menos una vez después del comienzo del tratamiento con el inhibidor de la farnesil transferasa, y (iii) comparar dichos nivel del marcador, donde una disminución del nivel del marcador medido en la muestra de sangre sin tratar con el nivel del marcador medido en la muestra de sangre tratada indica una respuesta al tratamiento.

inhibición de farnesil) después del que LPS (o el vehículo sólo sin tratamiento) se añadió a una concentración final de 10 ng/ml. Se recogieron los sobrenadantes a las 16 horas, 24 horas y 40 horas de tratamiento con LPS, y la secreción de IL-6 se cuantificó por ELISA. La importancia estadística para las diferencias en la producción de IL-6 en tipifarnib-versus PBMC tratado con vehículo se evaluó mediante la prueba t de Student. Las diferencias
5 estadísticamente significativas se indican con asteriscos ** significa valor medio de P inferior a 0,01. Cuanto menor sea el valor de P, más significativa es la diferencia.
La Figura 7a – 7b muestra el efecto de tipifarnib en LPS, TNF – α, y la señalización inducida por IL – 1. Las células THP – 1 se cultivaron en ausencia o presencia de 2 µM de tipifarnib durante 18 horas, a continuación se incubaron con LPS y TNF – α (Figura 7.a), o LPS, TNF – α eIL -1α (Figura 7.b) durante 30 minutos. Los lisados celulares se analizaron por inmunoelectrotransferencia, utilizando anticuerpos contra p38, p38 fosforilado, fosfo – ERK 1 / 2, IκB, y H – Ras.
La Figura 8 muestra que tipifarnib no inhibe la expresión del gen reportero dependiente de NF – κB inducida por
15 TNF – α. Las células HEK293 transfectadas en κB – LH se incubaron en ausencia o presencia de 2 y 5 µM de tipifarnib durante 18 horas, a continuación se estimularon con TNF – α durante 4 horas. La actividad de la luciferasa se midió y se expresó como un cambio múltiplo en presencia de TNF – α contra ningún TNF – α, o TNF – α / tipifarnib contra tipifarnib. Los valores se presentan como un factor de aumento ± D. E.
DESCRIPCIÓN DETALLADA DE LA INVENCIÓN Y REALIZACIONES PREFERIDAS
[0030] Los términos "que comprende", "que incluye" y "que contiene" se utiliza aquí en su sentido amplio, no limitado.
25 [0031] Los efectos biológicos de los FTI ahora se han elucidado aún más, como se discute en la sección Experimentos a continuación. La inhibición de la farnesil transferasa (FPTasa) se ha descubierto para regular a la baja los genes y proteínas identificadas en las Tablas 2, 3 y 4. Así, los niveles de dichos genes y proteínas pueden ser monitoreadas como marcadores biológicos para determinar la respuesta de un paciente al tratamiento con un FTI. Por ejemplo, diversos subconjuntos de genes y/o proteínas inducidos por LPS que se muestran en las tablas siguientes pueden ser regulados a la baja por la administración de un inhibidor de farnesiltransferasa y por lo tanto utilizarse como marcadores en los estudios clínicos.

farnesiltransferasa, según lo medido por el análisis de microarrays de ADNc

[0109] Las Tablas 1a, 1b, 1c y 1d muestran los genes inducida por LPS que fueron inhibidos por la simvastatina o tipifarnib. Los genes fueron seleccionados (véase Tabla 1A para la descripción de genes) como LPS inducido si la relación entre LPS tratados y no tratados con muestras fue mayor que 1,5-veces en más de dos puntos de tiempo. 5 Estos se muestran como números en negrita cursiva en el "factor de cambio (LPS versus control)" de la columna (Tabla 1.b). La expresión génica durante el tratamiento con LPS y la estatina (simvastatina / LPS) (Tabla 1.c), o LPS y la IVR (tipifarnib / LPS) (Tabla 1.d), se comparó con el LPS solo en puntos de tiempo correspondientes. Genes que mostraron al menos 1,5 veces la disminución en la inducción por uno o ambos fármacos, en uno o más puntos de tiempo fueron seleccionados para su inclusión en la tabla. Los genes para el que se inhibe la inducción LPS de
10 acuerdo con estos criterios se muestran como números negativos, negrita y cursiva.
[0110] Los resultados del análisis de microarrays se confirmó por los genes seleccionados por análisis en tiempo real PCR (Figura 2). La transcripción de IL-1 p fue inducida por LPS tan pronto como 3 horas, y la inducción no se vio afectada por la simvastatina o tipifarnib hasta este punto de tiempo. Sin embargo, después de 6 horas, y en 15 mayor medida, después de 12 horas de la inducción inducida por LPS significativamente downregulated de simvastatina y tipifarnib (Figura 2.a). MCP-1 fue inducida por LPS a partir de 6 horas, y esta inducción fue inhibida significativamente por la simvastatina y tipifarnib (Figura 2.b). MMP-9 inducción por LPS aumentó hasta 12 horas, en cuyo tiempo del punto de una disminución del 50% en la inducción se observó para la simvastatina y la no inducción en presencia de tipifarnib (figura 2.c). La inducción de IL-8 por LPS fue evidente tan pronto como 3 horas y no fue 20 afectada por los fármacos en este punto de tiempo. A las 6 y 12 horas, la inducción de IL-8 fue inhibida por la simvastatina, mientras que la FTI no mostró ningún efecto significativo (figura 2.d). STAT1 inducción fue inhibida por tipifarnib a las 6 y 12 horas, mientras que la inhibición por la estatina sólo se observó a las 12 horas (figura 2.e). Factor de diferenciación mieloide, MyD88, el adaptador de tipo Toll respuestas mediadas por el receptor, se upregulated significativamente por LPS a 6 y 12 horas, y esto fue ligeramente inhibida por la simvastatina en 1225 horas (Figura 2.f). En contraste, tipifarnib mostraron una inhibición casi completa de MyD88 inducción, a niveles
