Using Metabolic Engineering to Connect Molecular Biology Techniques to Societal Challenges

Genetically modified organisms (GMOs) are a subject of broad curiosity and are mentioned in courses starting from introductory biology to bioethics to extra superior methods-focused molecular biology programs. Most often, GMOs are mentioned within the context of introducing a single protein-coding gene to supply a single desired trait in a crop. For instance, a commercially accessible package permits college students to check whether or not meals merchandise comprise GMOs by detecting the Bacillus thuringiensis delta-endotoxin gene, which confers resistance to European corn borers. We’ve got developed an 8-week laboratory module for upper-division undergraduates and graduate college students that builds upon college students’ primary understanding of GMOs to introduce them to the strategies used to sustainably produce commercially helpful merchandise in yeast via metabolic engineering.

On this course, college students use recombination-based strategies to assemble genes encoding complete metabolic pathways in Saccharomyces cerevisiae, carry out genetic screens to determine yeast genes that affect metabolite yield, and use error-prone PCR to optimize metabolic pathway perform. In parallel to those laboratory-based actions, college students interact with the societal affect of those approaches via case research of merchandise made by way of yeast metabolic engineering, similar to opioids, omega-Three fatty acids, and the Unimaginable Burger. On this report, we concentrate on these case research in addition to a person sustainability venture task created for this course.

This task, which spans the 8-week module, asks college students to search out examples of yeast metabolic engineering that could possibly be used to deal with present sustainability challenges of their communities. By the top of the course, college students synthesize this data to create a case research that could possibly be used to show ideas associated to metabolic engineering and sustainability to their friends. Pupil approaches to this venture have different from literature critiques, to information searches, to instantly contacting and interviewing researchers utilizing novel metabolic engineering approaches. These student-produced initiatives are used as case research in future semesters, amplifying pupil voices and contributing to pupil possession. Whereas developed within the context of this course, the sustainability venture and case research are broadly relevant and could possibly be tailored to be used in biology or bioethics programs on the undergraduate or graduate degree. By this report, we hope to realize collaborators eager about implementing a model of the course at their establishments, permitting for sturdy evaluation of the affect of the course on a bigger group of scholars.

One-carbon epigenetics and redox biology of neurodegeneration

One-carbon metabolism gives the methyl teams for each DNA and histone tail methylation reactions, two of the primary epigenetic processes that tightly regulate the chromatin construction and gene expression ranges. A number of enzymes concerned in one-carbon metabolism, in addition to a number of epigenetic enzymes, are regulated by intracellular metabolites and redox cofactors, however their expression ranges are in flip regulated by epigenetic modifications, in such a manner that metabolism and gene expression reciprocally regulate one another to keep up homeostasis and regulate cell progress, survival, differentiation and response to environmental stimuli. Rising proof highlights the contribution of impaired one-carbon metabolism and epigenetic modifications in neurodegeneration.
This text gives an outline of DNA and histone tail methylation adjustments in main neurodegenerative problems, particularly Alzheimer’s illness, Parkinson’s illness and amyotrophic lateral sclerosis, discussing the contribution of oxidative stress and impaired one-carbon and redox metabolism to their onset and development. On-line schooling has grown quickly in recent times with many universities now providing absolutely on-line diploma applications even in STEM disciplines. These applications have the potential to broaden entry to STEM levels for folks with social identities at the moment underrepresented in STEM. Right here, we ask to what extent is that potential realized by way of pupil enrollment and grades for a completely on-line diploma program. Our evaluation of information from greater than 10,000 course-enrollments compares pupil demographics and course grades in a completely on-line biology diploma program to demographics and grades in an equal in-person biology diploma program on the identical college.
We discover that ladies, first-generation to school college students and college students eligible for federal Pell grants represent a bigger proportion of scholars within the on-line program in comparison with the in-person mode. Nevertheless, the net mode of instruction is related to decrease course grades relative to the in-person mode. Furthermore, African American/Black, Hispanic/Latinx, Native American, and Pacific Islander college students in addition to federal Pell grant eligible college students earned decrease grades than white college students and non-Pell grant eligible college students, respectively, however the grade disparities had been related amongst each in-person and on-line pupil teams.

A systems-biology view of viruses explains why they don’t seem to be alive

Whether or not or not viruses are alive stays unsettled. Discoveries of big viruses with translational genes and enormous genomes have saved the controversy energetic. Right here, a contemporary method is launched, primarily based on the organisational definition of life from inside methods biology. It views dwelling as a round means of self-organisation and self-construction which is ‘closed to environment friendly causation’. How data combines with pressure to manufacture and organise environmentally obtained supplies, given an vitality supply, is right here defined as a bodily embodiment of informational constraint. Evaluating a normal virus replication cycle with Rosen’s (M,R)-system exhibits it to be linear, slightly than closed.
Some viruses contribute appreciable organisational data, however up to now none is thought to provide all required, nor the fabric nor vitality needed to finish their replication cycle. Because of this, no recognized virus replication cycle is closed to environment friendly causation: in contrast to mobile obligate parasites, viruses don’t match the causal construction of an (M,R)-system. Evaluation primarily based in figuring out a Markov blanket in causal construction proved inconclusive, however utilizing Built-in Data Principle on a Boolean illustration, it was potential to point out that the causal construction of a virocell shouldn’t be totally different from that of the host cell.
