Antibiotics, Toxins, and Protein Engineering

The lethal poison Ricin (best known as a weapon of bioterrorism), Diphtheria toxin (the causative agent of a highly contagious bacterial disease), and the widely used antibiotic tetracycline have one thing in common: They specifically target the cell’s translational apparatus and disrupt protein synthesis.
In this course, we will explore the mechanisms of action of toxins and antibiotics, their roles in everyday medicine, and the emergence and spread of drug resistance. We will also discuss the identification of new drug targets and how we can manipulate the protein synthesis machinery to provide powerful tools for protein engineering and potential new treatments for patients with devastating diseases, such as cystic fibrosis and muscular dystrophy.
This course is one of many Advanced Undergraduate Seminars offered by the Biology Department at MIT. These seminars are tailored for students with an interest in using primary research literature to discuss and learn about current biological research in a highly interactive setting. Many instructors of the Advanced Undergraduate Seminars are postdoctoral scientists with a strong interest in teaching.

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

DNA: The Human Body Recipe

Educational Use
Rating
0.0 stars

As a class, students work through an example showing how DNA provides the "recipe" for making our body proteins. They see how the pattern of nucleotide bases (adenine, thymine, guanine, cytosine) forms the double helix ladder shape of DNA, and serves as the code for the steps required to make genes. They also learn some ways that engineers and scientists are applying their understanding of DNA in our world.

The course applies molecular biology and reverse genetics approaches to the study of apoptosis, or programmed cell death (PCD), in Drosophila cells. RNA interference (RNAi), or double stranded RNA-mediated gene silencing, will be used to inhibit expression of candidate apoptosis-related genes in cultured Drosophila cells. Teams of 2 or 3 students will design and carry out experiments to address questions about the genes involved in the regulation and execution of PCD in this system. Some projects involve the use of DNA damaging agents or other cytotoxic chemicals or drugs to help understand the pathways that control a cell’s decision to undergo apoptosis. Instruction and practice in written and oral communication are provided.

FBXL6-HSP90AA1-c-MYC axis facilitates hepatocellular carcinoma

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Hepatocellular carcinoma, or HCC, is the second deadliest form of cancer. One protein that helps HCC cells grow and proliferate is c-Myc. But exactly how has remained unclear. Now, researchers have identified a separate protein that, with c-Myc, forms a positive feedback loop to keep HCC cells thriving. The protein is called FBXL6 and was identified by transcriptome RNA sequencing. Experiments showed that FBXL6 was significantly increased in HCC compared with normal tissues and correlated positively with c-Myc expression. Further tests revealed that FBXL6 stabilizes the heat shock protein HSP90AA1, which activates c-Myc. In turn, c-Myc binds to the promoter region of FBXL6 and activates its expression. This newly discovered FBXL6-HSP90AA1-c-MYC axis could play a critical role in sustaining HCC. Drugs designed to suppress this feedforward loop could help patients living with hepatocellular carcinoma..."

Biological function at the molecular level is particularly emphasized and covers the structure and regulation of genes, as well as, the structure and synthesis of proteins, how these molecules are integrated into cells, and how these cells are integrated into multicellular systems and organisms. In addition, each version of the subject has its own distinctive material.
7.012 focuses on the exploration of current research in cell biology, immunology, neurobiology, genomics, and molecular medicine.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Microbiome research has consistently been placed in the spotlight over the past two decades, and has shown tremendous promise in the fields of medicine, environmental science, food production, and agriculture. Life on Earth does not exist without microbes, and we may benefit from learning more about them. Yet, there is no common understanding amongst researchers of what a 'microbiome’ actually is. Researchers are now proposing a common definition of ‘microbiome’ to ensure better, more robust research across different disciplines. The authors build on the historical definition offered by Whipps and colleagues in 1988 using new research insights. Additionally, they highlight the importance of microbiomes as drivers for the health of many eukaryotic hosts, including humans and plants. The proposed amendments to the definition specify the elements of microbiome composition and their interactions..."

The video's transcript is also provided in full, with a portion provided below for preview:

"Antibiotic-resistant bacteria like carbapenem-resistant Enterobacteriaceae (CRE) pose a serious threat to human health. Some resistant pathogens can exist alongside our commensal microbiota at undetectable levels. Antibiotic use can lead to outgrowth of these subclinically colonized bacteria. A recent study sought to better understand the interaction between the gut microbiota and CRE during subclinical colonization and outgrowth. First, researchers exposed wild-type mice to the CRE _K. pneumoniae_. While the levels of _K. pneumoniae_ were not detectable after exposure, the post-exposure microbiome was disrupted. Then, administration of an antibiotic cocktail, ampicillin, vancomycin, or azithromycin induced _K. pneumoniae_ outgrowth while reducing overall microbial diversity. Vancomycin only induced outgrowth in a subset of mice. The researchers found these outgrowth-susceptible mice had differences in mRNA stability pathways and xylose abundance..."
