The present study investigated the immunohistochemical localization of heat shock protein 25 (HSP 25) of rat molar teeth during root formation. Most, probably all, cells of the epithelial rest of Malassez (ERM cells) had immunoreaction for laminin, a marker protein for basement membrane. During root formation, HSP 25 immunoreactivity was observed in(More)

A new inhibitor of DNA methyltransferase named DMI-1 has been discovered in the culture filtrate of Streptomyces sp. strain No. 560. DMI-1 was purified by extraction with ethyl acetate followed by Diaion HP-20SS and silica gel column chromatography. The structure of DMI-1 was determined to be 8-methylpentadecanoic acid (C16H32O2). DMI-1 is a novel inhibitor(More)
