Correlated expression profile of extracellular matrix-related molecules during the inflammatory response of the teleost fish gilthead seabream

Abstract:

Extracellular matrix (ECM) components, in addition to their structural functions, interact with cell surface receptors and intracellular components to modulate the transduction of signals for cell growth, differentiation, migration, proliferation, polarization, apoptosis and inflammation. Our previous findings in the gilthead seabream (Sparus aurata L.), a marine seasonal hermaphrodite teleost fish, have shown that both endocrine and immune stimuli modulate the expression of matrix metalloproteases (MMPs) and tissue inhibitors of MMP (TIMPs). In addition, collagen type I (COL1) induces the expression of some pro-inflammatory cytokines and MMPs in professional phagocytes. Consequently, in this study we use real-time RT-PCR to analyze the gene expression profile of several ECM-related molecules (MMP-2, -9 and -13, TIMP-2a, and -2b, COL1A1, and integrin β1a) in different organs of adult specimens as well as in …
