CC BY-NC-SA
Rating
0.0 stars

The goal of this course is to teach both the fundamentals of nuclear cell biology as well as the methodological and experimental approaches upon which they are based. Lectures and class discussions will cover the background and fundamental findings in a particular area of nuclear cell biology. The assigned readings will provide concrete examples of the experimental approaches and logic used to establish these findings. Some examples of topics include genome and systems biology, transcription, and gene expression.

0.0 stars

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:

"Apoptosis, a form of programmed cell death, plays critical roles in animal development and in repair of DNA damage. Since DNA damage is a major factor in cancer development, identifying the regulators of damage-induced apoptosis could help researchers develop treatments. A recent study investigated whether NHR-14, an important developmental protein in the model organism C. elegans, also contributes to damage-induced apoptosis . using mutant C. elegans that are especially susceptible to radiation-induced DNA damage. Deletion of the gene encoding NHR-14, which corresponds to HNF4 in humans, decreased radiation-induced apoptosis of sex cells without affecting the levels of normal (non-damage-induced) apoptosis, indicating a specific role in the damage-induced death pathway. Further exploration revealed that the NHR-14 gene acts “downstream” of the DNA damage checkpoint pathway and regulates the transcription of the genes egl-1 and ced-13 after DNA is damaged..."

Experimental Molecular Biology: Biotechnology II
Conditional Remix & Share Permitted

Rating
0.0 stars

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.

Rating
0.0 stars

This project-based laboratory course provides students with in-depth experience in experimental molecular genetics, using modern methods of molecular biology and genetics to conduct original research. The course is geared towards students (including sophomores) who have a strong interest in a future career in biomedical research. This semester will focus on chemical genetics using Caenorhabditis elegans as a model system. Students will gain experience in research rationale and methods, as well as training in the planning, execution, and communication of experimental biology.

Molecular Biology and Genetics in Modern Medicine

Rating
0.0 stars

This course provides a foundation for understanding the relationship between molecular biology, developmental biology, genetics, genomics, bioinformatics, and medicine. It develops explicit connections between basic research, medical understanding, and the perspective of patients. Principles of human genetics are reviewed. We translate clinical understanding into analysis at the level of the gene, chromosome and molecule; we cover the concepts and techniques of molecular biology and genomics, and the strategies and methods of genetic analysis, including an introduction to bioinformatics. Material in the course extends beyond basic principles to current research activity in human genetics.

The Online Macromolecular Museum
Rating
0.0 stars

The Online Macromolecular Museum (OMM) is a site for the display and study of macromolecules. Macromolecular structures, as discovered by crystallographic or NMR methods, are scientific objects in much the same sense as fossil bones or dried specimens: they can be archived, studied, and displayed in aesthetically pleasing, educational exhibits. Hence, a museum seems an appropriate designation for the collection of displays that we are assembling. The OMM's exhibits are interactive tutorials on individual molecules in which hypertextual explanations of important biochemical features are linked to illustrative renderings of the molecule at hand.

Why devote a site to detailed visualizations of different macromolecules? In learning about the intricacies of life processes at the molecular level, it is important to understand how natural selection has fashioned the structure and chemistry of macromolecular machines to suit them for particular functions. This understanding is greatly facilitated by the visualization of 3-dimensional structure, when known. So, if static views of molecules (even in stereo) are worth a thousand words, then interactive animations of molecules should be worth much more. Indeed, we have found the types of displays represented here invaluable in gaining an appreciation for the details of key biochemical processes.

As Carl Brandon and John Tooze stated in their classic text, Introduction to Protein Structure:
"Molecular biology began some 40 years ago with the realization that structure was crucial for a proper understanding of function. Paradoxically, the dazzling achievements of molecular genetics and biochemistry led to the eclipse of structural studies. We believe the wheel has now come full circle, and those very achievements have increased the need for structural analysis at the same time that they have provided the means for it."

It is our opinion that structural analysis should extend into the classroom: as students learn about cellular mechanisms it is important that they study the chemistry of the molecular machines involved. These considerations have motivated the construction of the OMM.

The OMM is part of a collaborative effort by faculty and students interested in macromolecular structure-function relationships. The primary authors of some tutorials are students of David Marcey and he serves as author, co-author and site editor, and assumes all responsibility for content. Any criticisms, suggestions, comments, or questions should be sent to him at: marcey@callutheran.edu. All tutorials are copyrighted.

The OMM was started in 1996 for a Molecular Biology class at Kenyon College, where DM was a professor in the Biology Department (1990-1999). The OMM is now developed and housed at California Lutheran University, where DM has been a professor since 1999.

"RNA interference (RNAi), a popular technique for gene silencing using double-stranded RNAs (dsRNAs), can be used to manage insect pests. Once eaten by insects, the dsRNAs target specific genes to reduce growth or cause death. Multiple factors affect RNAi efficiency, but it’s unknown if the gut microbiota, which encounters the ingested dsRNAs in the gastrointestinal tract, is a factor. A recent study investigated the effects of RNAi on a major tree pest, the willow leaf beetle, and explored the influence of the microbiome with molecular biology techniques. The ingested targeted dsRNAs were highly lethal to non-axenic beetles (with gut microbes) but were less lethal to axenic (microbe-free) beetles despite equivalent gene-silencing effects. All dsRNAs altered the microbiota composition and induced overgrowth of gut bacteria, especially Enterobacter and Pseudomonas, perhaps in part because their degradation provided food for the bacteria..."

"Type 2 diabetes mellitus often leads to muscle atrophy driven by diminished differentiation capacity in myoblasts. Myogenesis is complex, and while many involved pathways have been described, there may still be yet undiscovered therapeutic targets. With this goal in mind, a recent study combined experiments in diabetic mice and cultured myoblasts to identify key proteins in diabetes-induced atrophy. The gene for the relatively undescribed solute carrier Slc2a6, also known as glut6, was up-regulated during myogenic differentiation and down-regulated during diabetes-induced myopathy. Silencing Slc2a6 with RNAi in cell culture impaired differentiation and myotube formation. Transcriptomics and metabolomics revealed that Slc2a6 silencing disproportionally impacted the glycolysis pathway . Further experiments and analysis determined that Slc2a6 regulates myogenic differentiation in cultured myoblasts and that this regulation was partly through the glycolysis pathway..."
