Expression of genes that encode the annexin-1 and galectin-1 proteins in nasal polyposis and their modulation by glucocorticoid.

Unlabelled: Rhinosinusal polyps physiopathology is not fully understand, despite numerous hypotheses regarding its inflammatory process.

Aims: A prospective study regarding the gene expression of proteins: anexin-1 and galectin-1, which has an anti-inflammatory action and is modulated by steroids.

Materials And Methods: Eleven patients with rhinosinusal polyps suffered a biopsy of their polyps at two moments: in the absence of systemic steroids and during its use.
