Retinoic acid-enhanced invasion through reconstituted basement membrane by human SK-N-SH neuroblastoma cells involves membrane-associated tissue-type plasminogen activator.

Abstract excerpt

Al-trans retinoic acid (RA) enhanced human, S-type, SK-N-SH neuroblastoma cell invasion of reconstituted basement membrane in vitro but did not induce terminal differentiation of this cell line. In contrast to basal invasion, which was urokinase (uPA)- and plasmin-dependent, RA-enhanced invasion was dependent on tissue-type plasminogen activator (t-PA) and plasmin activity. Neither basal nor RA-enhanced invasion...
