Abstract
Introduction

Matrix metalloproteinases (MMP) are a family of endopeptidases involved in extracellular matrix degradation and which could potentially explain specific histological changes in nasal polyposis. The aim of this study is to determine whether MMP-2 and 9 are involved in chronic rhinosinusitis with polyposis.

Material and method

Specimens were collected from 15 patients affected by nasal polyposis and 15 control patients (with turbinoplasty performed). Specimens were processed for determination of protein expression levels by Westernblot and for determination of their enzymatic activity by zymography for both MMPs.

Results

Results showed a higher expression and activity of MMP-9 but not of MMP-2 in specimens from patients with polyposis when compared with controls.

Conclusions

These results support the involvement of MMP-9 in the tissue remodelling characteristic of this disease.

Resumen
Introducción

Las metaloproteinasas de matriz (MMP) son un conjunto de endopeptidasas implicadas en la degradación de la matriz extracelular, que podrían explicar los cambios histológicos característicos de la poliposis nasal. El objetivo de este estudio consiste en determinar la implicación de MMP-2 y MMP-9 en la rinosinusitis crónica con poliposis nasal.

Material y método

Para ello, se tomaron muestras de 15 pacientes afectados de poliposis nasal y muestras de 15 controles intervenidos de turbinoplastia. Las muestras se procesaron para análisis de la expresión de ambas MMP mediante Western blot, y para determinación de su actividad enzimática mediante cimografía.

Resultados

Los resultados mostraron un incremento de la actividad y de la expresión de MMP-9, pero no de MMP-2, en las muestras procedentes de pacientes afectados de poliposis nasal en comparación con los controles.

Conclusiones

Estos resultados apoyarían la implicación de la MMP-9 en la remodelación tisular característica de esta enfermedad.
