Antiperiostin/POSTN Antibody Picoband® fluoro550 Vervoeging

POSTN (Periostin), also known as PN or OSF2, is a protein that in humans is encoded by the POSTN gene. The International Radiation Hybrid Mapping Consortium mapped the POSTN gene to chromosome 13. Gillan et al. (2002) found that purified recombinant PN supported adhesion of ovarian epithelial cells. Shao et al. (2004) found that periostin was overexpressed by the majority of human primary breast cancers examined. Transfected tumor cell lines overexpressing periostin showed accelerated growth and angiogenesis as xenografts in immunocompromised animals. Kuhn et al. (2007) showed that extracellular periostin induced reentry of differentiated mammalian cardiomyocytes into the cell cycle.
