Determination Of Methylation And Mirna-7 Levels For Predicting The Response To A Platinum-Based Antitumor Compound

Abstract

[ES] Determinación de la metilación y niveles de un miARN en respuesta a un compuesto antitumoral basado en platino. La presente invención se relaciona con un método para determinar la respuesta a un compuesto antitumoral basado en platino en una paciente de cáncer de ovario que comprende (i) determinar el nivel de metilación en la isla CpG de secuencia SEQ ID NO:1 y (ii) comparar el nivel de metilación en dicha isla CpG en el gen que codifica miR-7 o el nivel de expresión de miR-7 con un valor de referencia correspondiente, en donde un incremento en el nivel de metilación obtenido en (i) o una disminución en el nivel de expresión obtenido en (i) con respecto al valor de referencia correspondiente, es indicativo de que el cáncer de ovario de dicha paciente es resistente a dicho compuesto de platino. La invención también se relaciona con el uso de miR-7 o un precursor del mismo para la fabricación de un medicamento para el tratamiento de un sujeto que padece un cáncer resistente a un compuesto antitumoral basado en platino.

[EN] The invention relates to a method for determining the response to an antitumour compound comprising platinum in a patient with ovarian cancer, said method comprising (i) determining the level of methylation in the CpG island of sequence SEQ ID NO:1, and (ii) comparing the level of methylation in said CpG island in the gene encoding miR-7 or the expression level of miR-7 with a corresponding reference value, in which an increase in the methylation level obtained in (i) or a decrease in the expression level obtained in (i) with respect to the corresponding reference value indicates that the patient's ovarian cancer is resistant to said platinum compound. The invention also relates to the use of miR-7 or a precursor thereof for the production of a drug for the treatment of a patient with a cancer that is resistant to a platinum-based antitumour compound.
