Novel Cell Penetrating Peptide for Drug Delivery
Professor Min Xue and his lab at the University of California, Riverside have developed a novel hydrophilic endocytosis-promoting peptide (EPP6) rich in hydroxyl groups with no positive charge that may be used for drug delivery purposes. This peptide is non-toxic and has been shown to transport a wide array of small-molecule cargos into a diverse panel of cells. It enables oral administration and absorption through the intestinal lining, and crosses the BBB in vivo. UCR EPP6 is advantageous over existing technologies since it is nontoxic, efficiently enables oral absorption and transport across the BBB. Fig 1: A) Structure of the UCR EPP. B) Confocal images showing that EPP6 was able to transport different cargo molecules into the cells. C) Orally administered EPP6 is absorbed by the intestines, entering the blood circulation and reaching the brain.
Novel EphA4 Agonists for the Treatment of ALS
Researchers at the University of California, Riverside (UCR) in collaboration Nationwide Children’s Hospital have developed and characterized small peptidomimetics that act as EphA4 agonists. Given ALS is a heterogeneous disease, astrocytes reprogrammed from the fibroblasts of patients with sporadic and SOD1-linked ALS (iAstrocytes) were cultured with MNs and the UCR/Nationwide EphA4 agonists. As seen in Fig. 1, these small agonistic peptidomimetics decrease MN death in iAstrocytes derived from sporadic ALS (sALS) cells.
Highly Selective MMP-12 Antibodies
Researchers from the University of California, Riverside have developed potent monoclonal antibody inhibitors with high MMP-12 selectivity. These antibodies have applications in pharmaceuticals and biomedical sciences. Specifically, these antibodies may be developed as therapies for inflammatory and neurological diseases.

New Device to Test for Pulmonary Function for 21st Century Care
Prof. Mona Eskandari, whose research is known for seminal strides in experimental characterization and computational modeling of lung structural mechanics using novel techniques developed in her lab, has discovered a new method for measuring pulmonary function. It works by analyzing the change in temporal pressure while a patient is holding their breath. The measurement device is simple, comfortable and error-free for the patient to self-administer. Algorithms are used to transform the detailed lung data collection into actionable metrics for early detection capabilities for medical intervention and prevention. The discovery could provide more accessible, detailed, timely, and actionable data on lung function compared to conventional and currently used methods.

Brief description not available
Anti-Influenza Small Molecule Therapy
Professor Jiayu Liao from the University of California, Riverside has identified small molecules that block the Influenza B virus (IBV) from replicating by inhibiting the SUMOylation pathway. This IBV virus replication inhibition works by using the novel SUMOylation inhibitor, STE025, to inhibit the SUMOylation of the IBV M1 protein. SUMOylation also has active roles in the pathogenesis of several diseases, such as tumorigenesis, neurodegenerative diseases and infections, and as such, this technology could potentially be applied to these types of diseases as well. Fig 1: Cell death induced by IBV infection can be rescued by the UCR SUMOylation-specific inhibitor, STE025 (blue) compared to cells not exposed to IBV (green), and cells exposed to IBV without the UCR inhibitor (purple and red).
Novel Genetic Switch for Inducing Gene Expression
Prof. Sean Cutler and colleagues at the University of California, Riverside have engineered a system and methods to induce gene expression in plants and organisms, including mammals, using the chemical compound mandipropamid. Using the PYR/PYL/HAB1 promoter system, the PYR1/HAB1 system is reprogrammed to be activiated with mandipropamid. When the PYR1/HAB1 system dimerizes through chemical induced dimerization (CID) with mandipropamid, the system functions as a control switch for gene expression. This technology has been demonstrated to advantageously accelerate citrus breeding. It may be applied to improve CAR T-cell therapy and agricultural crops. Fig 1: UCR’s PYR1/HAB1 system is programmed through chemical induced dimerization (CID) initiated by mandipropamid to function as a switch for agrochemical control of gene expression.

Methods to Prevent and Treat Diffuse Large and Other B Cell Lymphomas
Professor Ameae Walker from the University of California, Riverside, Professor Srividya Swaminathan from the City of Hope Beckman Research Institute and their colleagues have developed a method for the prevention and treatment of B cell lymphomas. This technology works by systemically inhibiting expression of one form of the set of cell surface molecules that allow cells to respond to prolactin. This highly specific technology suppresses the deleterious downstream effects of prolactin that promote and sustain abnormal B cells. This invention is advantageous compared to existing technologies: all measures in mouse models and analysis of human cells suggest it is nontoxic and therefore will have significantly fewer, if any, side effects. It may also be used together with anti-psychotics that elevate prolactin. Finally, the technology includes a method for screening populations susceptible to development of DLBCL and other B lymphomas for early signs of disease. Antimaia Acts at Three Stages of B Lymphoma Development: 1) Antimaia, a splice modulating oligonucleotide (SMO) that decreases expression of the long form of the prolactin receptor, reduces the number of premalignant cells and the formation of abnormal antibody-producing cells. This also improves the symptomatology of autoimmune disease. 2) Antimaia prevents the conversion of premalignant to overt malignant B cells. 3) Antimaia kills B lymphoma cells. Antimaia works by reducing the number of long and intermediate form prolactin receptors (LF/IF PRLR) without effect on short receptors (SFPRLR).
