Mammalian Cell Culture Optimization

Biotherapeutic proteins manufactured in cell culture systems have transformed modern medicine. Selling many tens of billions per year, new biotherapeutics such as monoclonal antibodies have delivered dramatic clinical results, while posing significant manufacturing problems.: During the cell culture manufacturing process, toxic bioproducts such as lactate and ammonia have posed considerable challenges in bioprocessing, since they limit cell growth and impact critical quality attributes of recombinant protein production (e.g., therapeutic drugs, enzymes). That is because the lactate alters the regulation of biosynthetic enzymes, and can lead to changes in pH in the culture. To mitigate the negative effects of lactic acid accumulation and control the culture pH, chemical ‘base’ is added to the media during the course of a bioprocess. However, the base addition negatively impacts the bioprocess by inhibiting growth and shortening the length of time in which the cells can produce the recombinant protein. This leads to reduced yield, and increased cost-of-goods. Thus, it is of great interest to eliminate lactate production, and UC San Diego researchers have recently developed a new process for achieving this.

There is currently limited use for these waste streams. In some cases, pulps are dried, pelleted, and repurposed as an inexpensive livestock feed, however this application is barely profitable due to high production costs. There is a need for technologies that can cost-effectively transform pectin-rich waste streams into value-added products of commercial interest.   UC Berkeley researchers developed an efficient microbial strain technology and metabolic fermentation methods for the bioconversion of pectin-rich waste streams to useful bio-based commodity chemicals and biofuels. In addition to the beneficial environmental impact of utilizing a waste-stream, the fermentation technologies achieve three design goals set to optimize the productivity of bioconversions and economic viability. First, the technology allows for anaerobic fermentation, eliminating the need for culture oxygenation. This lowers operating costs by simplifying the metabolic requirements of high-density fermentation cultures. Second, co- utilization of the major component monosaccharides in the hydrolysate broth allows for productive conversion of the predominant, energy- rich biomass sugars. Third, fermentations can be conducted at low pH, discouraging contaminant growth and eliminating the need to buffer the hydrolysate mixture.

Salmonella-Based Gene Delivery Vectors and their Preparation

Nucleic acid-based gene interference technologies, including ribozymes and small interfering RNAs (siRNAs), represent promising gene-targeting strategies for specific inhibition of mRNA sequences of choice. A fundamental challenge to use nucleic acid-based gene interfering approaches for gene therapy is to deliver the gene interfering agents to appropriate cells in a way that is tissue/cell specific, efficient and safe. Many of the currently used vectors are based on attenuated or modified viruses, or synthetic vectors in which complexes of DNA, proteins, and/or lipids are formed in particles, and tissue-specific vectors have been only partially obtained by using carriers that specifically target certain cell types. As such, efficient and targeted delivery of M1GS sequences to specific cell types and tissues in vivo is central to developing this technology for gene targeting applications. Invasive bacteria, such as Salmonella, possess the ability to enter and transfer genetic material to human cells, leading to the efficient expression of transferred genes. Attenuated Salmonella strains have earlier been shown to function as a carrier system for delivery of nucleic acid-based vaccines and anti-tumor transgenes. Salmonella-based vectors are low cost and easy to prepare. Furthermore, they can be administrated orally in vivo, a non-invasive delivery route with significant advantage. Thus, Salmonella may represent a promising gene delivery agent for gene therapy. Scientists at UC Berkeley have developed a novel attenuated strain of Salmonella, SL101, which exhibited high gene transfer activity and low cytotoxicity/pathogenicity while efficiently delivering ribozymes, for expression in animals. Using MCMV infection of mice as the model, they demonstrated that oral inoculation of SL101 in animals efficiently delivered RNase P-based ribozyme sequence into specific organs, leading to substantial expression of ribozyme and effective inhibition of viral infection and pathogenesis. This strategy could easily be adopted deliver other gene targeting technologies.

Redirecting Cytosol Lipid Droplets for Enhanced Production

Background: Lipids (oils) produced by plants and photosynthetic microorganisms are used for general cooking, health food, cosmetics, pharmaceuticals and biodiesel. The current methods to produce oils with photosynthetic microorganisms are inefficient, since the cells must undergo extreme stress for lipid droplet (LD) accumulation and then be killed for extraction. Accumulation of LDs in the cytosol generates metabolic feedback inhibition. Some of these problems also apply to oil production with plants. A more efficient production practice is needed to meet high consumer and commercial demands.  Brief Description: UCR researchers have developed a method to optimize oil synthesis in microorganisms and plants by redirecting cytosolic LDs to the cell vacuoles. They successfully identified and modified a specific protein involved in directing lipids to various areas within the cell. Through restructuring and adding novel peptides, researchers were then able to re-route the fate of lipids into vacuoles (storage warehouses), thus eliminating metabolic feedback inhibition. Currently, they are also working towards achieving redirection of lipids to the cell exterior for excretion.

Fluorescent Biosensor for Methyltransferase Assay

Correct epigenetic regulation is essential to cellular development, and methyltransferases are enzymes important for epigenetic regulatory processes. They add methyl groups to their substrates, which can be DNA, proteins, or small-molecule secondary metabolites. Methyltransferases have been implicated in a number of diseases, including cancer, HIV infection, and diabetes, yet many remain uncharacterized.S-adenosyl methionine (SAM) is used as a methyl group donor by a majority of methyltransferases. Use of SAM by a methyltransferase results in the production of S-adenosyl homocysteine (SAH). SAM is found across all branches of life, and therefore represents a useful biological marker for methyltransferase activity. Researchers at UC Berkeley have developed a sensitive and selective means of assaying methyltransferase activity. This assay monitors the presence of SAH, and can be used for high-throughput screening.

Background: Biomolecular imaging is important in understanding characteristics of molecules and analyzing quantitative  data for research. Gold has been used for Surface Plasmon Resonance (SPR) which is utilized  for biomolecular imaging. Because of Gold’s high stability structurally and chemically, it is resourceful in this sort of technology.  Compared to Gold, Silver does not have as strong of a stability in non ideal chemical environments, but has high reactivity, supports strong surface plasmon polarization modes, and has higher storage of electrical energy than Gold.Description: UCR researchers have created Silver-Gold  alloy nanospheres through annealing techniques which may be used in SPR that creates optimal and effective results.  By annealing the Silver and Gold metal alloy, it has shown remarkable stability in harsh chemical environments, extremely narrow bandwidths, and shows large extinction pathways. These  specific characteristics enable many plasmonic applications with high performance and long lifetime, especially any involving corrosive species making the Silver-Gold alloy the most favorable choice for SPR.

Improvements to Producing Biofuel from Cyanobacteria

Generating fuel and chemicals from the photosynthesis of cyanobacteria has great potential – especially in comparison to other approaches to producing biofuels. However, improving the efficiency of the cyanobacteria photosynthetic process is necessary to lowering the production costs of the resulting biofuel – so that it is more cost-competitive with conventional fuels. To address this opportunity, researchers at the University of California, Berkeley have developed a novel approach to improving the photosynthetic efficiency of cyanobacteria. This Berkeley innovation is based on minimizing the phycobilisome light-harvesting antenna, and it has shown an increase in the saturation of photosynthesis by a factor of about two. This increase in efficiency in a population of cells would decrease the cost associated with producing isoprene, beta-phellandrene, and other chemicals from cyanobacteria photosynthesis.
