Osteoarthritis is a whole-joint disease characterized by the progressive destruction of articular cartilage involving abnormal communication between subchondral bone and cartilage. Our team previously identified 14-3-3ε protein as a subchondral bone soluble mediator altering cartilage homeostasis. The aim of this

Human pancreas, kidney, and liver alanine aminopeptidases have similar if not identical antigenic determinants even though these three isoenzymes have distinctly different electrophoretic mobilities. Single precipitin lines without spur formation were obtained for all three enzymes with antisera obtained from

A 50.4-fold purification of aminopeptidase is achieved by alcohol precipitation, DEAE-cellulose, CM-cellulose and finally Sephadex G-200 chromatography. On polyacrylamide gel electrophoresis of the purified enzyme after molecular sieving on Sephadex G-200, only one band was obtained, suggesting that the enzyme
