One such target is EMMPRIN (Extracellular Matrix Metalloproteinase Inducer). It has been shown that EMMPRIN expression is linked to various cell signaling pathways that lead to an increase in tumor cell vascularization. Researchers are focusing efforts on elucidating the role of EMMPRIN in a number of disorders including cancer, arthritis, tissue repair and numerous inflammation-dependent diseases. DESCRIPTION/DETAILS Basigin is a member of the immunoglobulin superfamily thatis also known as EMMPRIN. Human basigin is expressed as two differentiallyspliced isoforms encoded by a single gene found on chromosome, renamedrespectively as basigin-1 and basigin-2. Attempts to demonstrate specifichemophilic on separate cells, or between soluble forms of recombinant basiginusing surface Plasmon resonance have not been successful, suggesting thatbasigin-2 cannot function as a receptor for itself. In order to identify possible receptors for soluble basiginligand, an affinity purification approach was employed. This approach resulted inthe labeling of several potential interacting proteins, and MALDI MS/MSsequencing of one of these proteins identified a novel isoform of human basigin(basigin-3). Immunoprecipitation studies using cell fractions revealed thatrBSG interacts with basigin-2 at the cell membrane, and subsequently interactswith the basigin-3 isoform within the cell. Small-interfering RNA (siRNA)knockdown of basigin-2 protein reduced, but did not eliminate, rBSG-mediatedERK activation in HESCs, suggesting that additional cell surface receptors forsoluble basigin may exist. Taken together, these results support the hypothesisthat basigin-2 can function as a receptor for soluble basigin and demonstratethat the hemophilic interactions between basigin proteins are not dependentupon glycosylation of the basigin ligand. It has also been shown that soluble EMMPRIN binds tomembrane-bound EMMPRIN and the bound complex is internalized presenting apotential means to deliver therapeutic compounds to the cell in a highlytargeted manner. A therapeutic scheme isproposed that aims to design EMMPRIN-conjugates designed to deliver cancertherapeutics in a targeted fashion. Applications Conjugation oftherapeutics to EMMPRIN increases specificity and targets cancers cells cancer (skin, bladder,breast); other inflammatory diseases (arthritis, endometriosis); Upregulationof inflammatory response. Benefits It is possible to design therapeutic agents directed toward human basigin. Possible therapeutic scheme to block tumor progressionor inflammation.

Geometric cues facilitate the reprogramming of somatic cells by providing curvature and pinch points that guide proliferation, chromatin architecture, and mesenchymal-to-epithelial transition (MET), which are major indicators of active reprogramming. The technology comprises a kit for somatic cell reprogramming that includes a micropatterned object and immobilized cell adhesion agent. Benefits: A non-genetic method for cellular reprogramming Method saves time and enhances efficiency of reprogramming

Read More Dr. van der Donk from the University of Illinois has characterized expression vectors and a family of proteases that are useful in removing affinity tags after protein expression. Affinity tag removal after protein expression is sometimes necessary for the protein of interest to be functional and active. However during this tag removal, some amino acids not native to the protein of interest can be left behind. Dr. van der Donk's invention eliminates the possibility of extraneous amino acids being left on the final protein product, which is an improvement over existing enzymatic tag removal techniques. This invention has identified a class of lanthipeptides, class II LanPs that show substrate specificity and can serve as efficient sequence-specific traceless proteases, expanding and advancing the current toolbox of proteases. The general goal of Dr. van der Donk's research is to understand enzymatic transformations that are of environmental or pharmaceutical importance. The van der Donk lab utilizes both synthetic organic chemistry and molecular biology to reach this goal. Specifically, the lab uses genome mining strategies to discover new natural products, use microbiology and genomic tools to determine their mode of action, use chemical biology techniques to study their biosynthesis, and use synthetic chemistry to improve their activities and therapeutic properties.

The apparatus includes one or two ultrasound emitting devices (transducers) that first apply an acoustic radiation force to vibrationally displace a sphere embedded in the medium. Alternatively, a biopsy needle may be inserted into the medium and vibrated along its axis to generate shear waves. During and after vibration, ultrasound is again applied to image shear waves in the medium that propogate from the vibrating sphere or needle. By measuring the local wavelength of the shear waves, the shear modulus and viscous coefficient of the medium surrounding the vibrating element are estimated.

Embodiments of the system and method may use a generalized linear-class large tip angle approximation to design RF pulses for multi-channel and parallel transmission. Further, some of these approximations allow for the design of arbitrarily large flip angles, irregularly-shaped flip angle profiles, or arbitrary initial magnetization values. Embodiments of the system and method may also provide for the design of k-space trajectories which aid in maintaining assumptions of the various linear class approximations.
