“Objective: To evaluate the interaction of articular cartilage (AC) and subchondral bone (SB) through analysis of osteoarthritis (OA)-related genes of site-matched tissue.

Design: We developed a novel method for isolating

site-matched overlying AC and underlying SB from three and four regions of interest respectively from the human knee tibial plateau (n = 50). For each site, the severity of cartilage changes of OA were assessed histologically, and the severity of bone abnormalities were assessed by microcomputed tomography. An RNA isolation procedure was optimized that yielded high quality RNA from site-matched AC and SB tibial regions. Quantitative polymerase chain reaction selleck chemicals (Q-PCR) analysis was performed to evaluate gene expression of 61 OA-associated genes for correlation with cartilage integrity and bone structure parameters.

Results: A total of 27 (44%) genes were coordinately up- or down-regulated in both tissues. The expression levels of 19 genes were statistically significantly

correlated with the BEZ235 severity of AC degeneration and changes of SB structure: these included: ADAMTS1, ASPN, BMP6, BMPER, CCL2, CCL8, COL5A1, COL6A3, COL7A1, COL16A1, FRZB, GDF10, IVIMP3, OGN, OMD, POSTN, PTGES, TNFSF11 and WNT1.

Conclusions: These results provide a strategy for identifying targets whose modification may have the potential to ameliorate

pathological alterations and progression of disease in both AC and SB simultaneously. In addition, this is the first study, to our knowledge, to overcome the major difficulties related to isolation of high quality RNA from site-matched joint tissues. We expect this method to facilitate advances in our understanding of the coordinated molecular responses of the whole joint organ.

“BACKGROUND: Fructosyltransferase synthesizes fructo-oligosaccharides from sucrose. Data used in this work were obtained by an enzyme produced by Rhodotorula sp., a microorganism isolated from fruit samples from the Brazilian Atlantic Forest, which was immobilized in an inorganic support, consisting of a niobium and graphite alloy.

RESULT: All essays were conducted using enzymes at two purification grades, highly and partially purified enzymes, as comparison. The results were not significantly different between the two enzyme grades, mainly concerning the final fructo-oligossacharides yield, which were around 46%. Concerning the kinetics, the enzyme follows the Michaelis-Menten equation with inhibition by sucrose (above 60%). Also, a competitive inhibition by glucose was observed on sucrose, kestose and nystose uptakes.
