    Abstract Semimembranosus tendon avulsion fractures are an uncommon occurrence and are often associated with anterior cruciate ligament (ACL) and medial meniscus tears. We present the imaging features of an unusual case of semimembranosus avulsion fracture of the posteromedial tibial plateau associated with posterior cruciate ligament (PCL) tear, medial meniscus tear, and capsular rupture in a 26-year-old man with a football injury.

    Abstract Four decades have passed since the first discovery of collagen IV by Kefalides in 1966. Since then collagen IV has been investigated extensively by a large number of research laboratories around the world. Advances in molecular genetics have resulted in identification of six evolutionary related mammalian genes encoding six different polypeptide chains of collagen IV. The genes are differentially expressed during the embryonic development, providing different tissues with specific collagen IV networks each having unique biochemical properties. Newly translated alpha-chains interact and assemble in the endoplasmic reticulum in a chain-specific fashion and form unique heterotrimers. Unlike most collagens, type IV collagen is an exclusive member of the basement membranes and through a complex inter- and intramolecular interactions form supramolecular networks that influence cell adhesion, migration, and differentiation. Collagen IV is directly involved in a number of genetic and acquired disease such as Alport's and Goodpasture's syndromes. Recent discoveries have also highlighted a new and direct role for collagen IV in the development of rare genetic diseases such as cerebral hemorrhage and porencephaly in infants and hemorrhagic stroke in adults. Years of intensive investigations have resulted in a vast body of information about the structure, function, and biology of collagen IV. In this review article, we will summarize essential findings on the structural and functional relationships of different collagen IV chains and their roles in health and disease.

    Abstract The expression pattern, subcellular localization, and the role of glycosylation of the human nephrin was examined in transfected cells. Stable cell lines, constitutively expressing a full-length human nephrin cDNA construct, were generated from transfected immortalized mouse podocytes (IMP) and a human embryonic kidney cell line (HEK-293). Immunofluorescence confocal microscopy of transfected cells showed plasma membrane localization of the recombinant nephrin. Immunoblotting showed that the recombinant nephrin expressed in transfected cell lines migrated as a double band with a molecular weight of 185 kD. When cells were treated with the N-glycosylation inhibitor, tunicamycin, the molecular weight of nephrin was decreased to a single immunoband of 150 kD, indicating that the shift in the electrophoretic migration of nephrin is due to N-linked carbohydrate moieties. It was further shown that this glycosylation process is highly sensitive to inhibition by tunicamycin, which is a naturally occurring antibiotic, leading to retention of nonglycosylated nephrin molecules in the endoplasmic reticulum. It was concluded that N-glycosylation of nephrin is crucial for its proper folding and thereby plasma membrane localization; therefore, inhibition of this process might be an important factor in the onset of pathogenesis of some acquired glomerular diseases.

    Abstract The α-chains of the collagen superfamily are encoded with information that specifies self-assembly into fibrils, microfibrils, and networks that have diverse functions in the extracellular matrix. A key self-organizing step, common to all collagen types, is trimerization that selects, binds, and registers cognate α-chains for assembly of triple helical protomers that subsequently oligomerize into specific suprastructures. In this article, we review recent findings on the mechanism of chain selection and infer that terminal noncollagenous domains function as recognition modules in trimerization and are therefore key determinants of specificity in the assembly of suprastructures. This mechanism is also illustrated with computer-generated animations.

    Abstract Nephrin is a 180-200-kDa transmembrane protein of the immunoglobulin superfamily. In the kidney, nephrin localizes to the slit diaphragm (SD) between interdigitating podocyte foot processes and mutations in the nephrin gene cause congenital nephrotic syndrome. In addition to this rare genetic disorder, recent reports indicate that nephrin is more generally involved in the pathogenesis of glomerular disease. In this report, we describe production and characterization of mouse monoclonal antibodies to human nephrin, and discuss their applications. Recombinant human nephrin variants were produced in both prokaryotic and eukaryotic expression systems and purified proteins were used in an immunization protocol. A total of 16 antibodies were characterized for their reactivity with the nephrin by using ELISA, Western blots, immunoprecipitation and immunostaining of frozen and formaldehyde-fixed paraffin embedded tissue sections. The antibody epitopes were mapped using a variety of recombinant human nephrin variants. The detailed screening and characterization proved to be essential in order to find the most suitable antibody for each application. These antibodies will find wide use in studies of human nephrin and its involvement in kidney disease.

    Abstract Recent discoveries in podocyte proteins involved in the renal filtration barrier have shed new light on the ultrastructure of the kidney filter and pathogenesis of proteinuria. The identification of nephrin, a component of the slit diaphragm, and the intracellular slit diaphragm associated proteins CD2AP and podocin has demonstrated the existence of proteins that directly contribute to a functional kidney filter. Mutations in the genes for these three proteins result in proteinuria and nephrotic syndrome, and these proteins are also likely to be involved more generally in the pathomechanisms of proteinuria. This new knowledge has been promoted particularly through the powerful methods of molecular genetics and molecular biology. In this minireview, we present the recent progress in research of the podocyte slit diaphragm.

  9. Article: Identification of N-linked glycosylation sites in human nephrin using mass spectrometry.

    Abstract Nephrin is a type-1 transmembrane glycoprotein and the first identified principal component of the glomerular filtration barrier. Ten potential asparagine (N)-linked glycosylation sites have been predicted within the ectodomain of nephrin. However, it is not known which of these potential sites are indeed glycosylated and what type of glycans are involved. In this work, we have identified the terminal sugar residues on the ectodomain of human nephrin and utilized a straightforward and reliable mass spectrometry-based approach to selectively identify which of the ten predicted sites are glycosylated. Purified recombinant nephrin was subjected to peptide-N-glycosidase F (PNGase F) to enzymatically remove all the N-linked glycans. Since PNGase F is an amidase, the asparagine residues from which the glycans have been removed are deaminated to aspartic acid residues, resulting in an increase in the peptide mass with 1 mass unit. Following trypsin digestion, deglycosylated tryptic peptides were selectively identified by MALDI-TOF MS and their sequence was confirmed by tandem TOF/TOF. The 1 Da increase in peptide mass for each asparagine-to-aspartic acid conversion, along with preferential cleavage of the amide bond carboxyl-terminal to aspartic acid residues in peptides where the charge is immobilized by an arginine residue, was used as a diagnostic signature to identify the glycosylated peptides. Thus, nine of ten potential glycosylation sites in nephrin were experimentally proven to be modified by N-linked glycosylation.
