New Bright Green Fluorescent Proteins

Fluorescent proteins (FP) have been widely used as research tools in both academia and pharma for many years.  Naturally occurring FP have been mutated to either be brighter, be monomers, and/or for easier folding and expression in cells.  The most common FP to date has been the green fluorescent protein (GFP) of the jelly fish Aequorea victoria which can be expressed in cells and fused with proteins of interest, and has proven to be an excellent tool to study protein localization, expression, signaling, etc. in real time via microscopy and other techniques. 

Antibody and Vaccine Therapy for C. diff. Infection

Clostridium difficile (C. diff.) infection is estimated to cause nearly 0.5 million illnesses in the US. C. diff. can cause severe gastrointestinal effects, including life-threatening inflammation, is contagious, and is an urgent antibiotic-resistant threat, according to the Centers for Disease Control and Prevention. UCI researchers have determined the crystal structure for the virulent C. diff. toxin, TcdB, and characterized sites to target for neutralization along with immunogens that can be used in vaccine strategies to prevent and treat C. diff. infection.

Simultaneous Detection Of Protein Isoforms And Nucleic Acids From Low Starting Cell Numbers

Embryo-specific nucleic acid modifications, including retrotransposon activity-derived genomic modifications and alternative splicing of mRNA, is crucial for the development of mammalian embryos. However, determining if all genomic modifications and mRNA isoforms translate to protein variations remain intriguing questions due to difficulty in measuring protein isoforms and nucleic acids from small starting cell numbers.    UC Researchers have developed a system for performing dual nucleic acid and protein isoform measurements on low starting cell numbers equivalent to the number of blastomeres composing early embryonic development stages (morula and blastocysts).  The system integrates fractionation polyacrylamide gel electrophoresis (fPAGE) with off-chip analysis of nucleic acids in the nuclei. An additional method can be used to remove nuclei for off-chip analysis. The system can measure expression of protein isoforms from the cytoplasmic fraction of 1-100 cells while achieving analysis of either DNA or mRNA retained in the nuclei. The researchers have demonstrated signal from immunoprobed protein correlates strongly with protein expression prior to lysis in TurboGFP-expressing cells and that mRNA levels correlate with protein abundance in TurboGFP-expressing cells.

Synthetic Algal Promoters as a Tool for Increasing Nuclear Gene Expression in Green Algae

Algae have enormous potential as bio-factories for the efficient production of a wide array of high-value products, and eventually as a source of renewable biofuels. However, tools for engineering the nuclear genomes of algae remain scarce and limited in functionality, in part due to lack of strong promoters.

DNA Amplification by Electric Field Cycling (efc-PCR)

Polymerase Chain Reaction (PCR) is a popular technique for amplifying and quantifying minute quantities of DNA. Technologies based on PCR are used for a wide range of applications, including forensics, disease detection, and laboratory tools. Researchers at UCI have developed a device that can implement a novel method for PCR based on voltage cycling as opposed to temperature cycling (the current method for PCR). This allows the device to be much more portable and compact than those currently available.

Novel Cyanobacteriochromes Responsive to Light in the Far-Red to Near-Infrared Region

Fluorescent Biosensor for Cyclic GMP-AMP (cGAMP)

The cGAS-cGAMP-STING pathway is an important immune surveillance pathway which gets activated in presence of cytoplasmic DNA either due to a microbial infection or a patho-physiological condition, including cancer and autoimmune disorders. Sensing 2’3’ cGAMP level is important in diagnostics perspective as well as in basic understanding of their regulation.  Small molecule activators of this pathway have also been shown to activate an anti-cancer immune response and thus an important use for pharmaceutical applications. However, a high throughput method to screen for such potential drugs is still not available. UC Berkeley researchers have designed a RNA-based fluorescent biosensor for directly detecting 2’3’ cGAMP. The biosensor was able to detect 2’3’ cGAMP and assay cGAS activity in vitro and thus would be useful for high throughput screening of small molecule modulators of cGAS activity.  The biosensor was sensitive enough to quantify 2’3’ cGAMP in dsDNA- stimulated mammalian cell extracts. 

Transposon Vector for Vertebrate & Invertebrate Genetic Manipulation

Background: Therapeutic delivery of genes is a rapidly evolving technique used to treat or prevent a disease at the root of the problem. The global transgenic market is currently $24B, growing at an annual projected rate of 10%. Currently, a variation of this technique is widely used on animals and crops for production of desirable proteins, but this is a heavily infiltrated market. Thus, entering the gene therapy segment is more promising and would enhance the growth of this industry.  Brief Description: UCR Researchers have identified a novel transposon from Aedes aegypti mosquitoes. This mobile DNA sequence can insert itself into various functional genes to either cause or reverse mutations. They have successfully developed a transposon vector system that can be used in both unicellular & multicellular organisms, which can offer notable insight to improve current transgenic technologies as well as methods of gene therapy.
