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.

Stimuli Responsive Immunostimulants

An immune response typically occurs during inflammation, auto-immune diseases, or cancers. In such cases, chemical triggers, or immunostimulants, recognized by receptor proteins at cell membranes activate the immune cells. Researchers can use these immunostimulants to test how different cell subsets contribute to immune response mechanisms. This invention describes a novel type of immunostimulant that can be toggled on and off, both inside the body and in vitro.

The field of the invention generally relates to methods and devices used in diffuse optical spectroscopy. More specifically, the field of the invention generally relates to broadband diffuse optical spectroscopy methods and devices which are able to dynamically monitor multiple in vivo tissue chromophores.

microfluidic device for preparation of monodisperse microcapsules and microvesicles

Many applications, ranging from in vivo cell culture growth to drug delivery, rely on microcapsules to encapsulate and protect cells or molecules until their desired release. These microcapsules are typically generated in immiscible fluid, which must be depleted before they can be effectively used. Researchers at UCI have recently developed a paper-based microcapsule extraction technique that is quicker, cheaper, and less damaging than conventional methods.

Compositions and Methods using RNA Splicing Modulation to Selectively Impair Leukemic Cancer Stem Cells

The advancing age of the US population and increasing exposure to chemotherapy (for other malignancies) has resulted in increased rates of myelodysplastic syndrome (MDS). Following on the heels of MDS is progression to therapy-resistant acute myeloid leukemia (AML), which is predicted to rise significantly over the next few decades.  The heterogeneity of molecular abnormalities in therapy-resistant secondary acute myeloid leukemia (sAML) combined with a paucity of effective treatment options has resulted in high relapse-related mortality rates. In addition to approved therapies, many experimental agents also target epigenetic regulators of gene expression in clinical trials for sAML. However, most of these agents fail to improve patient survival, suggesting that epigenetic modifier therapies may reduce leukemic burden but may not effectively target a subpopulation of therapy-resistant leukemia stem cells that drive relapse. Hence, there is a critical need for developing clinical candidates with different modes of action. Recent studies implicate the spliceosome as a therapeutic vulnerability in solid tumors.

This invention describes novel fusion proteins that protect ubiquitylated forms of the target proteins from degradation.

Disposable Mouse Urine Collection Device

The ability to collect clean mouse urine in sufficient quantities for metabolic studies has been difficult to achieve due to the small volumes collected and the resulting contamination with feces with urine, especially when it is necessary to collect samples over of period of 24 hours. The cages currently available for this purpose are cumbersome, expensive, and complex and they often do not provide clean collections and the mouse urine is subject to evaporation within 24 hours, thus leaving a very small volume and inaccurate total volumes. Another potential issue with the current collection cages is their stability, especially during movement from one mouse room to another or from one vivarium to another. Also, the cages do not hold up to repeated washings, which can lead to potential contamination. Alternatively, simple procedures to collect mouse urine by placing mice on a plastic wrap are often not consistent and dependent on the lab handler.

Diseases characterized by copper hyper accumulation are currently challenging to identify due to costly diagnostic tools that involve extensive technical workup.   To solve these problems, UC Berkeley researches developed a simple yet highly selective and sensitive diagnostic tool along with new materials that can enable monitoring of copper levels in biological fluid samples without complex and expensive instrumentation.  The diagnostic tool includes a robust three-dimensional porous aromatic framework (PAF) densely functionalized with thioether groups for selective capture and concentration of copper from biofluids as well as aqueous samples.  The PAF exhibits high selectivity for copper over other biologically relevant metals, with a saturation capacity reaching over 600 mg/g.  The researchers were able to use the diagnostic tool, which included a colorimetric indicator, to identify aberrant elevations of copper in urine samples from mice with Wilson’s disease and also traced exogenously added copper in serum. 

Optical Phase Retrieval Systems Using Color-Multiplexed Illumination

Light is a wave, having both an amplitude and phase. Our eyes and cameras, however, only see real values (i.e. intensity), so cannot measure phase directly. Phase is important, especially in biological imaging, where cells are typically transparent (i.e. invisible) but yet impose phase delays. When we can measure the phase delays, we get back important shape and density maps.   Researchers at the University of California, Berkeley have developed a new method for recovering both phase and amplitude of an arbitrary sample in an optical microscope from a single image, using patterned partially coherent illumination. The hardware requirements are compatible with most modern microscopes via a simple condenser insert, or by replacing the entire illumination pathway with a programmable LED array, providing flexibility, portability, and affordability, while eliminating many of the trade-offs required by other methods. This enables quantitative imaging of phase from a single image, using partially coherent illumination, and in a way that is flexible and amenable to a variety of existing microscopy systems. 

System and Methods to Track Single Molecules

Tracking single molecules inside cells reveals the dynamics of biological processes, including receptor trafficking, signaling and cargo transport. However, individual molecules often cannot be resolved inside cells due to their high density in the cellular environment, plus it is difficult to see spatial and temporal features, such as signal transduction events at the cell surface or on intracellular compartments, with single molecule resolution. To address these problems, researchers at the University of California, Berkeley, have developed the PhotoGate device and methods in order to control the number of fluorescent particles in a region of interest. By deploying PhotoGate and applying patterned photobleaching, they have demonstrated the tracking of single particles at surface densities two orders of magnitude higher than the single-molecule detection limit. Additional experimentation enabled the observation of ligand-induced dimerization of epidermal growth factor receptors on a live cell membrane, and also measurements of the binding and the dissociation rate of single adaptor protein from early endosomes in the crowded environment of the cytoplasm. The innovative approach enables tracking of single particles at high spatial and temporal resolution, and for mapping of molecular trajectories, as well as determining complex stoichiometry and dynamics, and drives the art towards video-rate imaging of live cells with molecular (1–5 nm) resolution.
