Effect of somatostatin on MMP-9 expression.

Abstract

<p>(A) Zymographyc analysis of cell culture supernatants harvested after 24 hrs of incubation indicate that somatostain administration does not modulate gelatinolytic activity of MMP-9 in each of the experimental conditions. (B) In Western blotting analysis of cell lysates a polyclonal anti-MMP-9 antibody recognizes a single band corresponding to the pro-MMP-9 (92 kDa) which is not modulated over each experimental condition. Analysis of β-tubulin represents the internal control. The results presented are the means ± ES of three indipendent experiments in triplicate, n = 9.</p
