  1. MMP matrix metalloproteinases, NS not significant
  2. Activity levels have been measured by an image analysis program (IMAGEQUANT TL; Amersham Bioscience, Piscataway, NJ). An arbitrary unit (au) scale was used. They have been analyzed by a stastical software(PRISM 6 ver. 6.01, GraphPad Software). Data were expressed as average ± standard deviation (SD)
