Biotech Blog: USDA Should Establish a Science-Based Regulatory System to Address Genetically Engineered and Gene-Edited Crops

| May 15, 2017

The United States Department of Agriculture (USDA) has been regulating genetically engineered (GE) crops to ensure that they are not harmful to our agricultural system for over 20 years.  USDA regulates those crops based primarily on the technique used to introduce the new gene, and its oversight is not proportional to the potential risk of the introduced trait.  More recently, it has applied that same system to gene-edited crops.  Instead, USDA needs to establish a science-based regulatory system for both GE and gene-edited crops, in which the degree of oversight, if any, is determined by the potential risk of the engineered or edited crop’s new characteristic.

Defense biotech research looks to eliminate bacteria causing traveler’s diarrhea, reduce jet lag duration

Article | April 9, 2020

World traveler‘s will rejoice at the idea of a seemingly magical device that would guarantee they never suffer from the all-too-familiar stomach issues that come from traveling internationally while reducing jet lag at the same time. But it’s not just privileged globetrotters that would benefit from a device that eliminates the bacteria associated with the so-called Montezuma’s Revenge. In 2016, more than 230,000 children around the world died from some of the same types of bacteria as those that cause traveler’s diarrhea, and the bacteria mainly come from unsafe “drinking water, poor sanitation and malnutrition,” according to Oxford University’s Our World In Data portal. On Monday, DARPA announced it was researching an “implantable or ingestible bioelectronic carrier” that would eliminate the five major bacteria associated with traveler’s diarrhea.

Cell Out? Lysate-Based Expression an Option for Personalized Meds

Article | February 18, 2020

Cell-free expression (CFE) is the practice of making a protein without using a living cell. In contrast with cell line-based methods, production is achieved using a fluid containing biological components extracted from a cell, i.e., a lysate. CFE offers potential advantages for biopharma according to Philip Probert, PhD, a senior scientist at the Centre for Process Innovation in the U.K.

Learning How FoxA2 Helps Turn Stem Cells into Organs

Article | March 18, 2020

Scientists at the Perelman School of Medicine at the University of Pennsylvania discovered early on in each cell, FoxA2 simultaneously binds to both the chromosomal proteins and the DNA, opening the flood gates for gene activation. The discovery, “Gene network transitions in embryos depend upon interactions between a pioneer transcription factor and core histones,” published in Nature Genetics, helps untangle mysteries of how embryonic stem cells develop into organs, according to the researchers. “Gene network transitions in embryos and other fate-changing contexts involve combinations of transcription factors. A subset of fate-changing transcription factors act as pioneers; they scan and target nucleosomal DNA and initiate cooperative events that can open the local chromatin. However, a gap has remained in understanding how molecular interactions with the nucleosome contribute to the chromatin-opening phenomenon,” write the investigators.

Selexis Cell Line Development Strategies

Article | February 11, 2020

In today’s biotechnology landscape, to be competitive, meet regulations, and achieve market demands, “we must apply Bioprocessing 4.0,” said Igor Fisch, PhD, CEO, Selexis. In fact, in the last decade, “Selexis has evolved from cloning by limiting dilution to automated cell selection to nanofluidic chips and from monoclonality assessment by statistical calculation to proprietary bioinformatic analysis,” he added. Single-use processing systems are an expanding part of the biomanufacturing world; as such, they are a major component of Bioprocessing 4.0. “At Selexis, we use single use throughout our cell line development workflow. Currently, we have incorporated single-use automated bioprocessing systems such as ambr® and the Beacon® optofluidic platform for accelerated cell line development. By using these systems and optimizing our parameters, we were able to achieve high titers in shake flasks. Additionally, the Beacon systems integrate miniaturized cell culture with high-throughput liquid handling automation and cell imaging. This allows us to control, adjust, and monitor programs at the same time,” noted Fisch.
