3D-Bioprinted All-Inclusive Bioanalytical Platforms for Cell Studies

Common drug screen models, such as animals and 2D cell cultures, do not properly recapitulate human organ structure and environment. Using 3D bioprinting technology, researchers at UCI have developed all-inclusive customized organ-on-a-chip-like platforms. These platforms produce cell models that properly mimic the microenvironment of cells for drug screening and cell-therapeutic response studies.

Viral infection is a multistep process involving complex interplay between viral life cycle and host immunity. One defense mechanism that hosts use to protect cells against the virus are nucleic-acid-mediated surveillance systems, such as RNA interference-driven gene silencing and CRISPR-Cas mediated gene editing. Another important stage for host cells to combat virus replication is translational regulation, which is particular important for the life cycle of RNA viruses, such as Hepatitis C virus and Coronavirus.  While efforts to characterize structural features of viral RNA have led to a better understanding of translational regulation, no systematical approaches to identify important host genes for controlling viral translation have been developed and little is known about how to regulate host-virus translational interaction to prevent and treat infections caused by RNA viruses.   UC Berkeley researchers have developed a high-throughput platform using CRISPR-based target interrogation to identify new therapeutics targets or repurposed drug targets for blocking viral RNA translation.  The new kits can also be used to identify important domains within target proteins that are required for regulating (viral RNA translation) and can inform drug design and development for treating RNA viruses.

Microfluidic Dispenser for Automated, High-Precision, Liquids Handling

Development of Methods and Assay for Measurement of Total Oxidized Phospholipid (OxPL)

Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in the United States. It can be broadly sub-classified into nonalcoholic fatty liver (NAFL), which is thought to have minimal risk of progression to cirrhosis, and nonalcoholic steatohepatitis (NASH), which is thought to have an increased risk of progression to cirrhosis. The current diagnostic gold standard for differentiating whether a patient with NAFLD has NAFL versus NASH is liver biopsy. However, liver biopsy is an invasive procedure, which is limited by sampling variability, cost, and may be complicated by morbidity and even death, although rare. Accurate, non-invasive, biomarkers for the detection of liver disease and liver disease progression e.g., progression to NASH, are currently also not available.

Blood Flow Velocimetry via Data Assimilation of Medical Imaging

Cardiovascular disease (CVD) is a tremendous burden on the population in terms of morbidity and mortality, as well as on the healthcare system in terms of cost. Various forms of CVD including atherosclerosis, valve and ventricular dysfunction, aneurysms, and thrombogenesis can be identified by measuring localized abnormalities in blood flow. Accordingly, the ability to noninvasively interrogate physiological flows enables identification and diagnosis of disease, monitoring of the effects of therapy, and research on the hemodynamic nature of CVD and its associated interventions. In the clinic, blood flow measurements are primarily made using phase contrast magnetic resonance imaging (PC-MRI) and ultrasonic color Doppler imaging. Certain limitations of these techniques for patients who have contraindications or suffer from arrhythmias, as well as the desire for volumetric flow information necessitate the development of a new modality for blood flow velocimetry.

IgEvolution: A Novel Tool for Clonal Analysis of Antibody Repertoires

Constructing antibody repertoires is an important error-correcting step in analyzing immunosequencing datasets that is important for reconstructing evolutionary (clonal) development of antibodies. However, the state-of-the-art repertoire construction tools typically miss low-abundance antibodies that often represent internal nodes in clonal trees and are crucially important for clonal tree reconstruction. Thus, although repertoire construction is a prerequisite for follow up clonal tree reconstruction, the existing repertoire reconstruction algorithms are not well suited for this task because they typically miss low-abundance antibodies that often represent internal nodes in clonal trees and are crucially important for clonal tree reconstruction.

Breast Milk Biomarkers for Child Chronic Health Disorders

Autism Spectrum Disorder (ASD) is a developmental disorder associated with difficulties in social interaction and communication as well as repetitive behavior. ASD is thought to be the result of genetic and environmental factors that affect approximately 1 in 59 children in the US, and 25 million people worldwide. The current method of diagnosis for ASD involves evaluations and tests performed by a team of specialists.  The latest forms of diagnosis can detect ASD as early as 18 months. However, more standard methods take until 4 years of age before the diagnosis of ASD is confirmed. There remains an unmet need to develop a reliable and accurate diagnostic methods for early detection for a child at risk with chronic and/or developmental disorders, such as ASD, so that an early intervention measures will be applied before the first symptoms appear.

Potent and Selective Peptide Inhibitors for MMP-2

Prof. Min Xue and his colleague at the University of California, Riverside have developed peptide-based selective MMP-2 inhibitors with nanomolar activities. Unlike known MMP inhibitors, n-TIMP-2 and GM6001 that inhibit a broad spectrum of the MMP family, these peptide inhibitors do not exhibit off-target effects with other MMP family members such as MMP-9.  Fig. 1 shows how a proMMP2 inhibitor (orange) interferes with the protein-protein interaction (PPI) between proMMP2 and TIMP2 (tissue inhibitor of metalloproteinases 2). This PPI inhibition blocks the TIMP2-assisted proMMP2 activation process and thereby results in lower levels of active MMP2. Fig. 2 shows the novel UCR MMP-2 peptide binds to proMMP2 with an Kd of 2.3 nM and inhibits MMP2 activation with an IC50 of 20 nM.

TRM: Islet-mER-Cre-mER Mice

Insulin gene enhancer protein ISL-1 or ISL1 transcription factor, LIM/homeodomain is a highly conserved gene (UniProtKB-P61371). It binds to insulin gene enhancer sequences and is necessary for heart development. In addition, it plays an essential role in the gene regulatory network crucial for retinal ganglion cell (RGC) differentiation.

TRM: Wnt-11 Knock-Out Mice

The Wnt gene family is composed of a large number of secreted glycoproteins involved in a wide variety of cell interactions ranging from early to adult stage that play a role in morphogenesis, paterning and development. In contrast to the Wnt/β-catenin signaling pathway which most Wnt proteins signal through, Wnt-11 signals via the Wnt/JNK pathway. A recent study demonstrates that the expression of secreted factor Wnt-ll is elevated in several types of cancer, including colorectal cancer (2019 R. M. Kypta et al.)

Manumeter for Monitoring and Assessing Upper Extremity Rehabilitation

After an injury or neurological event, a patient’s rehabilitation requires long-term assessment and monitoring, especially in the upper extremities that are important for everyday tasks.UCI researchers have developed the Manumeter to quantitatively assess and log a patient’s hand movements without external therapist intervention.

A Microplatform For Performing High Throughput, Multiplexed Assays On Adherent Cells

Systems and methods are providing for performing high-throughput, programmable, multiplexed assays of biological, chemical or biochemical systems. Preferably, a micro-pallet includes a small flat surface designed for single adherent cells to plate, a cell plating region designed to protect the cells, and shaping designed to enable or improve flow-through operation. The micro-pallet is preferably patterned in a readily identifiable manner and sized to accommodate a single cell to which it is comparable in size. Each cell thus has its own mobile surface. The cell can be transported from place to place and be directed into a system similar to a flow cytometer. Since, since the surface itself may be tagged (e.g., a bar code), multiple cells of different origin and history may be placed into the same experiment allowing multiplexed experiments to be performed.
