Chemoenzymatic Synthesis Of Acyl Coenzyme-A Molecules

Acyl-CoAs is involved in both primary and secondary metabolism; it is an important intermediate molecule for in vitro enzymatic assays in research. Current chemical methods to generate acyl-CoAs rely on chemical ligation of carboxylic acids to commercially available coenzyme A molecule by the use of peptide coupling reagents. These couplings are inefficient and the final product is hard to purify. This process of acyl-CoA synthesis is therefore expensive.

A High-Throughput Screen For Drug And Disease Investigations In A Simple Neuronal Culture

Drug discovery and development consists of an arduous testing process, and cell-based screening methods represent a crucial source of information in the decision making process to evaluate mode of action, efficacy and toxicity for new therapeutics in early phases if preclinical drug development. Despite advances in cell-based screening assays, a need remains for newer and better assays to identify and validate drug s for treatment and/or prevention of neuronal diseases. Such newer assays should have a higher speed, lower cost, high sensitivity and high signal to noise ratio. Further, there needs to be improved methods for assessing toxicity of drug candidates.

Mechanism of Non-communicable Diseases and Methods for Assessing the Biological Effects of the Environment on an Organism

Of the 56 million global deaths in 2012, 68% were due to non-communicable diseases (NCDs) such as cardiovascular diseases, cancer, and respiratory diseases. Even in developing countries NCDs are rising rapidly and are projected to exceed infectious, maternal, perinatal, and nutritional diseases as the most common causes of death by 2030.While urbanization is associated with a rise in NCD, the biological consequence of persons transitioning from a rural to urban environment remain poorly understood.

Method For Fabricating Two-Dimensional Protein Crystals

2D crystalline materials possess high surface area-to-volume ratios, light and can be very porous. These properties have rendered synthetic 2D materials immensely attractive in applications including electronics, sensing, coating, filtration and catalysis. The rational design of self-assembling 2D crystals remains a considerable challenge and a very active area of development. The existing methods for the bottom-up fabrication of biological or non-biological 2-D crystalline materials are not generalizable and scalable. 2D protein design strategies, in particular, require extensive computational work and costly protein engineering. In addition, these strategies have low success rates, the resulting materials contain large defects, and are multi-layered and therefore not appropriate for scaling or materials-applications. Moreover, these strategies often require the presence of lipids for supported assembly.

Isolation Of A Gene That Regulates The Strength Of Abscisic Acid Signal Transduction

As climate change has an increasingly greater impact on the environment, some regions are likely to get wetter while other regions are going to get drier. Therefore there is need to identify new ways to render agricultural plants more drought tolerant and effective in limiting transpirational water loss. The plant hormone abscisic acid (ABA) regulates a plant’s many important responses to stress. In seeds, ABA is responsible for the accumulation of nutritive reserves, tolerance for desiccation, maturation and dormancy.During vegetative growth, ABA is central in triggering plant responses to drought, salt stress and cold.A rapid response to drought that is mediated by ABA is stomatal closure.Stomata on the leaf surface are formed by pairs of guard cells whose turgor regulates stomatal pore apertures. ABA induces stomatal closure by triggering cytosolic calcium increases, which regulate ion channels in guard cells. Therefore modulating ABA activity in plants can be used to confer drought tolerance on plants.

The high-density imaging arrays overcome drawbacks associated with existing high density arrays fabricated on a single surface and the more recent 3D droplet emulsion arrays.

Superresolution Microscopy And Ultrahigh-Throughput Spectroscopy

Current super-resolution microscopy (SRM) methods have excellent spatial resolution, but no spectral information. Issues such as heavy color crosstalk, compromised image quality, and difficulties in aligning 3D coordinates of different color channels mean that high-quality multicolor 3D SRM remains a challenge. Another current imaging technique, single-molecule spectroscopy, is also limited in use because current methods are low throughput, have low spatial resolution, and cannot be used effectively for densely labeled biological samples.   UC Berkeley researchers have developed a 3-D super-resolution microscopy and single molecule spectroscopy system that addresses the issues inherent to both of these imaging techniques. By synchronously measuring the fluorescence spectra and positions of millions of single molecules within minutes, both spectrally resolved SRM and ultrahigh-throughput single-molecule spectroscopy are made possible.

A Method For Predicting Glycosylation On Secreted Proteins

Glycosylation is a key post-translational modification that can affect critical properties of proteins produced in biopharmaceutical manufacturing, such as stability, therapeutic efficacy, or immunogenicity. However, unlike a protein's amino acid sequence, glycosylation is hard to engineer since it does not follow any direct equivalent of a genetic code. Despite various attempts to computationally model the process of glycosylation, industrial glycoengineering is still largely carried out using costly and time-consuming trial-and-error strategies and could greatly benefit from computational models that would better meet the requirements for industrial utilization.

Fast Micro- or Nano-scale Resolution Printing Methods and Apparatus

Fast, affordable three-dimensional printing or 3D manufacturing at micron or nano-scale is a holy grail for many high-tech industries. Current state of the art has generally been limited to smallest feature sizes in the 5-10 micron range, with metal-based 3D printer systems held at 100 microns. Another problem is 3D printers are limited to polymer media or require large laser sources. To address these issues, researchers at the University of California, Berkeley, have developed methods and devices to efficiently deposit desirable constituent materials (e.g. metallic, semiconducting, insulating, etc.) with precise micron and nano-scale resolution and without expensive laser requirements. These methods show promise in terms of fast sub-5 micron print speeds, material versatility, and structure sophistication. This is an entirely new fabrication tool, which is unencumbered by the limitations of existing 3D print-like functions, paving the way to arbitrary 2D and 3D nanoscale structures and devices that cannot be fabricated in any other way.

Mouse Cell Lines Mutant For Patched 1 And Patched 2

In mammals, the Hedgehog (Hh) family of proteins is essential for normal embryonic development and crucial for the homeostasis of adult tissues. Aberrant Hh signaling has been implicated in a number of cancers, including ovarian cancer. Sonic Hedgehog (Shh) is the best studied of the Hh proteins, with a well-characterized signaling pathway that involves binding to the receptors Patched 1 and Patched 2. This signaling pathway is activated in basal cell carcinomas and other tumor types.   UC Berkeley researchers have made a cell line mutant for all alleles of Patched 1 and Patched 2. This cell line provides a means to identify agents targeting the Hh pathway, as well as a means to test therapeutics. 

Novel Multivalent Bioassay Reagents

The guiding principle for the creation of biomolecular recognition agents has been that affinity is essential for both strength and specificity.  Monoclonal antibodies, the dominant workhorse of affinity reagents, have mono-valent affinities in the uM-nM range with apparent affinities that can be sub nM with the bi-valency intrinsic in intact immunoglobulin structure.  The avidin-biotin interaction used ubiquitously for biomolecular assembly is femto-molar and both highly specific and essentially irreversible.  High affinity has been proclaimed the essential goal for the selection of useful specific aptamers, though there has been disagreement about a tight coupling of affinity and specificity.
