Perlecan is a critical proteoglycan found in the extracellular matrix (ECM) of cartilage. In healthy cartilage, perlecan regulates cartilage biomechanics and we previously demonstrated perlecan deficiency leads to reduced cellular and ECM stiffness in vivo. This change in mechanics may lead to the early onset osteoarthritis seen in disorders resulting from perlecan knockdown such as Schwartz-Jampel syndrome (SJS). To identify how perlecan knockdown affects the material properties of developing cartilage, we used imaging and liquid chromatography–tandem mass spectrometry (LC-MS/MS) to study the ECM in a murine model of SJS, Hspg2C1532Y-Neo. Perlecan knockdown led to defective pericellular matrix formation, whereas the abundance of bulk ECM proteins, including many collagens, increased. Post-translational modifications and ultrastructure of collagens were not significantly different; however, LC-MS/MS analysis showed more protein was secreted by Hspg2C1532Y-Neo cartilage in vitro, suggesting that the incorporation of newly synthesized ECM was impaired. In addition, glycosaminoglycan deposition was atypical, which may explain the previously observed decrease in mechanics. Overall, these findings provide insight into the influence of perlecan on functional cartilage assembly and the progression of osteoarthritis in SJS.

John Solomon has worked overtime and then some to rip Adam Schiff’s mask off. So have Catherine Herridge, Sara Carter, Lee Smith, Gregg Jarrett, Kim Strassel, Mollie Hemmingway and Byron York. Solomon’s article highlights how utterly dishonest Adam Schiff is. Ditto with the upper echelon of the FBI. Strap yourself in. This isn’t a short ride. The pursuit of the truth ended Thursday when the Justice Department formally asked a court to vacate Flynn’s conviction and end the criminal case, acknowledging the former general had indeed been cleared by FBI agents and that the bureau did not have a lawful purpose when it interviewed him in January 2017. Attorney General William Barr put it more bluntly in an interview Thursday : “They kept it open for the express purpose of trying to catch, to lay a perjury trap for General Flynn.” According to Solomon’s reporting, the FBI didn’t have a reason to investigate Gen. Flynn: 3. Case closed memo. FBI agents wrote a memo to close the investigation of Flynn on Jan. 4, 2017, writing they found “no derogatory” evidence that Flynn committed a crime or posed a national security threat. FBI management then ordered the closure to be rescinded and pivoted toward trying lure Flynn into an interview. https://justthenews.com/accountability/russia-and-ukraine-scandals/fbi-found-no-derogatory-russia-evidence-flynn-planned Corrupt FBI agent Peter Strzok allegedly ordered Crossfire Razor, the codename for th
