The goal of the Genetic Origins Program is to allow students to use their own DNA variations (polymorphisms) as a means to explore our shared genetic heritage and its implications for human health and society. Genetic Origins focuses on two types of DNA variations: an Alu insertion polymorphism on chromosome 16 (PV92) and single nucleotide polymorphisms (SNPs) in the control region of the mitochondrial (mt) chromosome. With two alleles and three genotypes, PV92 is a simple genetic system that illustrates Mendelian inheritance on a molecular level. PV92 data is readily analyzed using population statistics. The mt control region is one of the simplest regions of human DNA to sequence. With a high mutation rate, the mt control region is the "classical" system for studying human and primate evolution. The Genetic Origins site and linked Bioservers site have all the information needed for students to perform the Alu and mt DNA experiments and analyze the results - including online protocols, reagents, animations and videos explaining key concepts, and database tools.

This course discusses the principles of genetics with application to the study of biological function at the level of molecules, cells, and multicellular organisms, including humans. The topics include: structure and function of genes, chromosomes and genomes, biological variation resulting from recombination, mutation, and selection, population genetics, use of genetic methods to analyze protein function, gene regulation and inherited disease.

Students conduct their own research to discover and understand the methods designed by engineers and used by scientists to analyze or validate the molecular structure of DNA, proteins and enzymes, as well as basic information about gel electrophoresis and DNA identification. In this computer-based activity, students investigate particular molecular imaging technologies, such as x-ray, atomic force microscopy, transmission electron microscopy, and create short PowerPoint presentations that address key points. The presentations include their own explanations of the difference between molecular imaging and gel electrophoresis.

This lesson uses the fundamentals of protein synthesis as a context for investigating the closest living relative to Tyrannosaurus rex and evaluating whether or not paleontologist and dinosaur expert, Jack Horner, will be able to "create" live dinosaurs in the lab. The first objective is for students to be able to access and properly utilize the NIH's protein sequence database to perform a BLAST, using biochemical evidence to determine T rex's closest living relative. The second objective is for students to be able to explain and evaluate Jack Horner's plans for creating live dinosaurs in the lab. The main prerequisite for the lesson is a basic understanding of protein synthesis, or the flow of information in the cell from DNA to RNA during transcription and then from RNA to protein during translation

This course introduces experimental biochemical and molecular techniques from a quantitative engineering perspective. Experimental design, rigorous data analysis, and scientific communication form the underpinnings of this subject.

"Lung cancer is the leading cause of cancer-related deaths globally. Tyrosine Kinase Inhibitors (TKIs) are a common treatment for lung cancer, but TKI resistance is widespread. TKI treatment also has serious side effects like hair loss, anemia, and hypothyroidism, meaning it is important to identify which patients will benefit from the treatment. MicroRNAs may be a way to do that. MicroRNAs regulate gene expression by blocking transcription or promoting the breakdown of messenger RNA, and because microRNAs are stable in body fluids, they can be particularly useful as diagnostic or prognostic indicators in many applications. In the context of anti-cancer drugs, microRNAs are frequently directly involved in the cellular response. Profiling their expression could be used to predict the response to anti-cancer drugs like TKIs. The research to date has described numerous microRNAs and their roles in TKI response by lung cancer cells. However, most previous research did not measure microRNAs in serum samples..."

"Wastewater treatment plants are a critical piece of infrastructure that depend on microbes, both resident and incoming. Incoming microbes can be beneficial but may include parasites that need to be removed. Resident microbes, meanwhile, help break down organic waste. While much is known about bacteria in wastewater treatment plants, eukaryotes are frequently overlooked. Recently, researchers examined the whole microbiome of 10 wastewater treatment plants in Switzerland. They utilized metagenomics to measure which microbes were present and metatranscriptomics to analyze their activity. Bacteria were the most numerous— but eukaryotes, particularly protists, showed the most activity, and there was a surprising number and range of active parasites, which were particularly prevalent in the inflow. Network analysis suggested predation by resident microbes likely helped remove parasites..."

"Cold shock domain containing E1, or CSDE1, is emerging as a powerful protein in the cell. Growing evidence suggests that CSDE1 reprograms how RNA codes are ultimately translated into proteins, which means CSDE1 could be pivotal in how cells respond to internal and external changes like those brought on by disease. In a new review, researchers outline a model that could explain CSDE1’s reprogramming ability. According to the model, CSDE1 acts as a connector between RNAs and the specific proteins capable of regulating or altering those RNAs. For regulating proteins that can’t normally bind to RNAs, CSDE1 provides a bridge between the two. For proteins that do bind to RNAs, CSDE1 enhances that connection, and for proteins that can but don’t typically bind to certain RNAs, CSDE1 reshapes those RNAs to make binding possible. How CSDE1 connects proteins to RNAs in response to stress isn’t yet clear, but equipped with this new model, researchers could begin to understand CSDE1’s role in human disease..."

"Cancer is a devastating disease that progresses when cells divide uncontrollably and spread to other parts of the body, but scientists have found that neighboring noncancerous cells are often able to inhibit the growth of tumor cells in a process known as contact normalization. Tumor cells must somehow overcome this inhibition to become malignant, but exactly how they do this has not yet been resolved. To fill this gap, researchers recently used microscopy, CRISPR, and RNA sequencing techniques to uncover how noncancerous cells influence adjacent cancerous cells. They found that contact normalization takes place when noncancerous cells use the protein N-cadhedrin to adhere to neighboring tumor cells. This results in a decrease in the expression of the protein podoplanin and the inhibition of tumor cell proliferation. The team also concluded that the presence of podoplanin enables cancerous cells to override contact normalization under continued N-cadherin expression..."
