Fibronectin is an adhesive glycoprotein found on cell surfaces, in the intracellular and extracellular matrix and in biological fluids. It was shown that fibronectin increases level of IGFBP5 in muscles In vitro. What is more, fibronectin plays a crucial role in muscle oxygenation during exercise.The aim of the study was to compare the expression of the fibronectin (FN1) gene in longissimus dorsi and semimembranosus muscles of pigs and then to determine the relationship between the level of the expression and the age of animals. Compared was also the level of FN1 expression in muscles among different pig breeds in order to establish if there are differences between commercial and primitive lines. The results did not show a clear expression pattern of FN1 during pig development. Higher expression of FN1 in semimembranosus than in longissimus dorsi was found in all breeds at almost all developmental stages.

Fibronektyna jest adhezyjną glikoproteiną obecną na powierzchni komórek, a także w macierzy wewnątrz- i zewnątrzkomórkowej oraz w płynach ustrojowych. Niezwykle ważną jej cechą jest udział w dotlenieniu mięśni podczas wysiłku. W badaniach in vitro wykazano, że zwiększa ona poziom IGFBP5.Celem pracy było oznaczenie ekspresji genu fibronektyny w mięśniach najdłuższym grzbietu i półbłoniastym szynki, a następnie określenie zależności między jej poziomem, a wiekiem i rasą świń. Stwierdzono wyższą ekspresję w mięśniu półbłoniastym niż najdłuższym grzbietu we wszystkich badanych rasach, jednak nie można na tej podstawie jednoznacznie określić profilu ekspresji w trakcie rozwoju.
