Development of Highly Sensitive Excitation Ratiometric Indicators of Cellular Phosphorylation

Protein phosphorylation is one of the most common forms of post-translational modification and is involved in the regulation of key signaling pathways in the cell. Dysfunctional phosphorylation plays a key role in various diseases, especially cancer and neurodegenerative disorders. Protein kinases have been the focus of intense recent interest by the pharmaceutical industry. Indeed, most new cancer drugs approved by the FDA in the last several years target kinases, and there are hundreds of new kinase inhibitors under development.  To this end, it is very important to have quantitative methods for measuring changes in kinase activities.  In vitro kinase activity assays take the target molecules out of cellular contexts. Fluorescent protein-based kinase biosensors have enabled the real-time monitoring of kinase activities within the native context of living cells, yet most commonly used biosensors exhibit poor sensitivity (e.g., dynamic range) for imaging physiological signaling activities in situ.

Nano Biosensing System

Metabolites can provide real-time information about the state of a person’s health. Devices that can detect metabolites are commercially available, but are unable to detect very low concentrations of metabolites. Researchers at UCI have developed surfaces that use nanosensors to detect much lower concentrations of such metabolites.

Method for Assessing Risk of Genetic Defects in Children by Identifying De Novo Mutations in Male Sperm

In general, the risk of having a child with autism spectrum disorder (ASD) is about 1 in 68, or 1.5%. But the risk goes up for families who already have a child with ASD. If a family has one child with ASD, the chance of the next child having ASD is about 20%. If the next child is a boy, the risk is 26%, whereas if it’s a girl the risk is 10%. About 47% of families had more than one child with autism. Currently if a child has a birth defect or autism, the emerging trend is to perform whole exome sequencing to identify genetic mutations. These mutations overwhelmingly come from the father, because sperm cells but not egg cells continue to divide through the life of adults. Once the mutation is identified, the diagnosis can be made in the child, but the parents are left wondering if this genetic event could recur in future children. Currently there is no genetic assessment of sperm available commercially, and no publications on the application of using sperm as a way to assess risk of childhood disease, nor is there a risk assessment available for couples that have had a child with a genetic disease due to de novo genetic mutation.

DNA Nanotechnology for Quick and Sensitive Detection of Nucleic Acids in Point-of-Care (POC) Diagnosis Applications

Researchers led by Dino Di Carlo from the Department of Bioengineering at UCLA have developed a quick, cheap, and accurate method to diagnose viral or bacterial infections.

Multi Layered Microfluidic Devices For In Vitro Large Scale Perfused Capillary Networks

"Organ-on-a-chip” technologies allow recapitulation of organ systems in vitro and can be utilized for drug response and toxicity studies, which are required in preclinical studies. However, current recapitulations via “organ-on-a-chip” technologies are limited because the designs do not fully reflect physiological complexity. To address this, UC Irvine inventors have developed a device to better mimic the vascular network of the circulatory system.

Antibody Selection to Prevent or Treat Alzheimer’s Disease

Therapeutic antibodies have been developed to prevent or slow the cognitive decline in Alzheimer’s disease (AD) but with limited clinical success to date. These treatment failures suggest that antibodies vary in their therapeutic efficacy and that more effective antibodies or combinations of antibodies need to be identified. To address this issue, researchers at UCI have developed a novel screening platform that can identify antibodies that may prevent or treat AD or other neurodegenerative disorders with high efficacy from human blood.

In vivo optical biopsy applicator of the vaginal wall for treatment planning, monitoring, and imaging guided therapy

Pelvic floor disorders (PFDs) afflict nearly 25% of all women and carry a host of symptoms that can drastically reduce quality of life. Despite their prevalence, the complex and varied nature of such PFDs make them difficult to diagnose and treat. Researchers at UCI have developed an entirely integrated system that, for the first time, provides real-time monitoring of the vaginal wall tissue during diagnosis and treatment, allowing for more thorough diagnoses and more effective treatment methods.

Endoscopic Optical Coherence Tomography As A Minimally Invasive Lung Cancer Screening Tool To Guide Diagnosis And Therapy
