CRISPR-Cas systems consist of Cas proteins, which are involved in acquisition, targeting and cleavage of foreign DNA or RNA, and a CRISPR array, which includes direct repeats flanking short spacer sequences that guide Cas proteins to their targets. The programmable nature of these systems has facilitated their use as a versatile technology that is revolutionizing the field of genome manipulation. There is a need in the art for additional CRISPR-Cas systems with improved cleavage and manipulation under a variety of conditions and ones that are particularly thermostable under those conditions.     UC researchers discovered a new type of RNA-guided endonuclease (GeoCas9) and variants of GeoCas9.  GeoCas9 was found to be stable and enzymatically active in a temperature range of from 15°C to 75°C and has extended lifetime in human plasma.  With evidence that GeoCas9 maintains cleavage activity at mesophilic temperatures, the ability of GeoCas9 to edit mammalian genomes was then assessed.  The researchers found that when comparing the editing efficiency for both GeoCas9 and SpyCas9, similar editing efficiencies by both proteins were observed, demonstrating that GeoCas9 is an effective alternative to SpyCas9 for genome editing in mammalian cells.  Similar to CRISPR-Cas9, GeoCas9 enzymes are expected to have a wide variety of applications in genome editing and nucleic acid manipulation.

Methods for Global RNA-Chromatin Interactome Discovery

Recent decades of genomic research reveal that mammalian genomes are more prevalently transcribed than previously anticipated. It is now quite clear that mammalian genomes express not only protein-coding RNAs but also a large repertoire of non-coding RNAs that have regulatory functions in different layers of gene expression. Many of those regulatory RNAs appear to directly act on chromatin, as exemplified by various long noncoding RNAs (IncRNAs). Some of those regulatory RNAs mediate genomic interactions only in cis, while others, such MALAT1 and NEAT1, are capable of acting in trans. These findings suggest an emerging paradigm in regulated gene expression via specific RNA-chromatin interactions. Various techniques have been developed to localize specific RNAs on chromatin. These methods, such as chromatin Isolation by RNA purification or comprehensive identification of RNA binding proteins (ChIRP), capture hybridization analysis of RNA targets (CHART), and RNA affinity purification (RAP), all rely on using complementary sequences to capture a specific RNA followed by deep sequencing to identify targets on chromatin. Importantly, all of these methods only allow analysis of one known RNA at a time, and up to date, a global view is lacking on all RNA-chromatin interactions, which is critical to address a wide range of functional genomics questions.

Amplifying and Detecting Nucleic Acids Within Crude Samples

Diagnosing diseases or determining compound safety often relies on bioassays to detect foreign nucleic acids (biomarkers) in crude biological, environmental, or pharmaceutical samples involving sample preprocessing which can be insensitive, timely, and expensive.

Antisense Oligonucleotides and Drug Conjugates for Obesity and Diabetes Treatment

The obesity epidemic is an ongoing issue leading to significant economic and social burden, in part due to its role in the development of diabetes. Only three DFA-approved drugs for obesity treatment currently exist, none of which are without significant side effects and risks. Researchers at UCI have developed a DNA-based approach that activates metabolism, to target genes only in the fat and liver, causing increased energy expenditure and weight loss without affecting other organs. These present a viable approach to obesity treatment with minimal side effects in comparison to current drug treatments.

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.

Aptamers that promote neuronal growth by binding to and blocking the protein Nogo

Neuronal growth inhibiting protein (Nogo), blocks regrowth of damaged neuronal projections (axons) in neurodegenerative disorders. Currently, researchers are developing antibody proteins to inhibit Nogo and produce axon regrowth in a variety of disorders. However, such antibodies are unstable and costly to synthesize. At UCI, the synthesis of nucleic acid molecules called aptamers that selectively bind and block Nogo to promote axonal growth presents a promising alternative pharmaceutical target for treating a range of disorders including spinal cord injury, stroke, Amyotrophic Lateral Sclerosis (ALS), and Multiple Sclerosis (MS).
