Abstract

Un método para evaluar el cáncer de pulmón, cáncer de colon, cáncer de mama o cáncer de ovario in vitro, que comprende medir en una muestra la concentración de: (a) proteína ARMET (rica en arginina, mutada en tumores en fase tempranas) y/o fragmentos de la misma. (b) opcionalmente uno o más marcadores adicionales de cáncer, y (c) usar el resultado de la medición de la fase (a) y opcionalmente de la fase (b) en la evaluación del cáncer, donde dicha muestra es suero o plasma, y donde un incremento de la concentración de una proteína ARMET y/o fragmentos de la misma es indicativo de cáncer de pulmón, cáncer de colon, cáncer de mama o cáncer de ovario

Análisis por LC-ESI-MSMS:
La digestión tríptica (100 µl) se separa mediante una HPLC bidimensional (MudPIT) en un sistema Nano-LC (Ultimate, Famos, Switchos; LC Packings, Idstein, Alemania). La separación se realiza con columnas bidimensionales 5 auto-empaquetadas (Sílice fundida: PicoFrit 75 µm, New Objective; RP: ProntoSil 120-5-C18 AQ+, Bischoff; SCX: Partisil 10, Whatman). Se generan 11 fracciones SCX mediante la elución en fases con cantidades crecientes sucesivamente de NH4Ac (de 0 a 1.500 mM). Estas se separan posteriormente en la parte RP de la columna y se analizan en línea usando escaneos dependientes de datos con una trampa de iones ESI-MS (LCQ deca XP; Thermo Electron, Massachusetts, E.E.U.U.; véanse los parámetros en la tabla X). Para cada muestra se realizan tres series.
10 Los datos brutos se procesan con un sistema no comercial de manejo de datos propio de Roche que usa Sequest como algoritmo de base (véase los parámetros en la Tab. X). Se combinaron las listas resultantes de péptidos identificados y proteínas de las series de réplicas.
La proteína ARMET se identifica con ayuda de las secuencias identificadas y que se dan en la Tab. 2. 15 Detección de ARMET como un marcador potencial de cáncer de pulmón:
Para cada paciente, se comparan las proteínas identificadas y el número de péptidos correspondientes de la muestra del tumor con los resultados que corresponden del tejido adyacente normal. De esta manera, se descubre que la 20 proteína ARMET está presente específicamente o es muy abundante en tejido tumoral y no es detectable o es difícilmente detectable en el tejido sano control.

25 La proteína ARMET está fuertemente sobre-representada en tejido tumoral de pacientes que padecen cáncer de pulmón. Las siguientes secuencias peptídicas de la proteína ARMET se identifican mediante la búsqueda en el formulario de la base de datos “LCQ-MS2-data” en tejido tumoral:
Usando el método descrito anteriormente se han identificado las siguientes secuencias derivadas de ARMET. 30 Tabla 2: Secuencias identificadas por ESI-MSMS
