A broad survey of the molecular and cellular factors that contribute to an understanding of selected human diseases. B M B 001 Understanding the Bases of Human Disease (3) (GN)(BA) This course meets the Bachelor of Arts degree requirements. B M B 001, Understanding the Bases of Human Disease, is a survey of the most common diseases of humans. In addition to discussing various diseases, symptoms, outcomes, prevention and treatment options, we also study disease processes by describing events at the cellular or DNA level. We will come to appreciate that various cellular, metabolic or genetic problems can give rise to disorders that carry a common name -anemia, for example. One form, Sickle Cell anemia, also provides a good example of another theme of the course: how a small genetically-based problem in one function of one cell type can lead to a cascade of malfunctions with ramifications system wide. How medicines work and how they are metabolized by the body will be discussed. Treatment of the growing problem of drug/drug, drug/food, and drug/"supplement' interactions will also be included.Any study of infectious disease must be prefaced by a discussion of the proper functioning of the immune system and how its various components work together to fight an infection. The proper function or malfunction of the immune system is also studied for relationships to noninfectious diseases such as cancer and certain genetic disorders. As with any system of the body, the immune system also has its own unique set of disorders: allergy, hypersensitivity, autoimmunity and immune deficiency - congenital and acquired.In our exploration of infectious diseases, we will look at various mechanisms of infection used by different types of organisms and at strategies the offending organisms might have to fool the immune system, hide from the immune system, or fight against it. A prime example is the ability of HIV to hide from the immune system. Knowing disease mechanisms and the life cycle of the infectious agent can suggest strategies for treatment of the disease. Another focus of this unit will include discussion of emerging and re-emerging diseases.Human genetic traits and susceptibilities are discussed throughout the course, but we will also address the major genetic disorders, patterns of inheritance, chromosomal disorders and new treatments available for a growing number of such disorders. Included under this topic is the problem of cancer in all of its various forms today. The course addresses issues of normal cell/cancer cell characteristics and the concept of cancer as a "genetic disease". Using the information gleaned from units on cell function, genetics and the immune system, we will explore new treatment options evolving today.No course on treatment of disease is complete without the study of the two major "lifestyle" diseases: coronary vascular disease and diabetes. We will explore the environmental factors as well as the genetic and infection- related factors often associated with these diseases.The course is independent of all other B M B courses and does not serve as a prerequisite for any other course.

Principles of the structure and function of biological molecules, including carbohydrates, lipids, membranes, proteins, and enzymes. BMB 401 is the first course of the general biochemistry series, a sequence designed to prepare students for careers and graduate study in the life sciences. Overall, biochemistry describes, in chemical and molecular terms, the structures, mechanisms, and chemical processes at work in all living things, and abstracts organizing principles that underlie life in all its diverse forms. Building upon concepts introduced in molecular and cellular biology and in organic chemistry, students in BMB 401 synthesize and apply this knowledge toward understanding the structure and function of the major classes of cellular constituents: water, and the various macromolecules -- amino acids and proteins, sugars, and polysaccharides, nucleotides and nucleic acids, fatty acids and lipids, and membranes and various membrane proteins. These molecules interact to comprise the next level of multi-and mixed molecular structures and organelles that enable a cell to carry out its many metabolic functions. Students also learn about the technologies used to study cellular components and processes, and current advances in biotechnology that have accelerated the pace of discovery in the field. Having gained familiarity with the molecules found in a cell, students are well-equipped to take on more advanced topics in the exciting, rapidly-evolving fields of the life sciences. An overriding theme in biochemistry is that polymers of living systems, though structurally large and functionally complex, are highly ordered chemical entities, with specific sequences of monomeric subunits giving rise to discrete structures and functions. The course includes all of the following topics: 1) an introduction to protein structure function relationships, covering the structural basis of protein functions; 2) enzyme kinetics and mechanisms; 3) simple and complex carbohydrates and topics in glycobiology that include energy storage, framework skeleton, and specific molecular recognition; 4) various classes of lipids, including phospholipids, complex lipids, membrane biology and transport systems, and 5) an analysis of the biochemical basis of signal transduction describing how specific signals regulate biomolecular activity both within a cell and between cells to keep an organism in homeostasis. Lastly, as a transition to intermediary metabolism in BMB 402, an introduction to bioenergetic principles is included to provide a framework for understanding pathways of carbon and nitrogen metabolism, using glycolytic reactions as an example. Students may not receive credit for both BMB 401 and CHEM 476 or BMB 401 and BMB 221

Next, students explore simple and complex carbohydrates and topics in glycobiology that include energy storage, framework skeleton, and specific molecular recognition. Various classes of lipids, including phospholipids, complex lipids, membrane biology and transport systems, are covered next. Following is an analysis of the biochemical basis of signal transduction describing how specific signals regulate biomolecular activity-within a cell, and between cells-to keep an organism in homeostasis. Lastly, as a transition to intermediary metabolism in BMB 402H, an introduction to bioenergetic principles is included to provide a framework for understanding pathways of carbon and nitrogen metabolism, using glycolytic reactions as an example. Students may not receive credit for both CHEM 476 and BMB 401H.
BMB 402 General Biochemistry (3) is a comprehensive survey of the pathways and regulation of intermediary metabolism. Most, if not all, of the students taking BMB 402 intend to pursue a Ph.D., M.D. or M.D./Ph.D. degree after graduation. Since biochemistry is an important discipline for advanced studies in life and medical sciences, a major goal of BMB 402 is to prepare students well for their future challenges in graduate or medical school. The major topics covered include glycolysis, TCA cycle, metabolism of fatty acids, lipids (phospholipids, cholesterol and sphingolipids), amino acids and nucleotides, signal transduction, and human genetic diseases. Since biochemistry is a very rapidly progressing discipline, any new developments not covered by the textbook are introduced in the lectures or via discussion of current scientific papers at an appropriate level. In addition, students must be able to integrate information learned from different but related material.

Laboratory in enzyme purifications and assay techniques; nucleic acid isolation and characterization, including plasmid preparation. BMB 442 / MICRB 442 Laboratory in Proteins, Nucleic Acids, and Molecular Cloning (3)The DNA portion of B M B/MICRB 442 serves as an introduction to fundamental techniques of recombinant DNA technology and as a reinforcement of principles of Molecular Genetics from lecture courses. The central experiment entails all basic procedures necessary to clone a gene, i.e. to make a recombinant molecule comprised of DNA from two sources. Students use restriction enzymes to cut two distinct DNA molecules into smaller fragments. The fragments are mixed and treated with the enzyme Ligase, which randomly combines small fragments into large recombinant DNA molecules in new combinations different in composition from either original molecule. The recombinant molecules, which include genes that confer drug resistance, are transformed intoE. coli cells that initially have no drug resistance. Cells that acquire recombinant DNA molecules are identified by selective plating on growth media containing drugs. From the transformed cells, recombinant DNA is isolated and analyzed by agarose gel electrophoresis, completing the array of basic gene cloning techniques. In addition to this central, multi-session experiment, students also do PCR and an investigation of the lac operon, a classic molecular genetic model system. The proteins portion of BMB 442 / MICRB 442 is designed to introduce students to protein biochemistry topics and laboratory techniques typically encountered in academic and commercial settings. Students will learn about buffers, spectroscopy, enzyme purification and characterization methods. Specifically, the experiments include preparation of buffers and performing kinetic studies to determine Km and Vmax values. Separation of a mixture of phycobiliproteins using ion-exchange column chromatography is a major experiment that the students will perform to learn protein purification methods. In this experiment they will learn how to pour a column, apply sample, elute it with salt gradient and collect fractions using automated fraction collector. Ammonium sulfate precipitation and dialysis will be part of protein purification procedures. Characterization of the separated proteins will be performed by determining the absorption spectra with spectrophotometer and by determining the molecular weights of the subunits of the phycobiliproteins by SDS-polyacrylamide gel electrophoresis.

Mechanisms and regulation of protein trafficking, organelle biosynthesis, cell development, signaling and cell cycle control. Emphasizes experimental design and analysis. BMB 460 / MICRB 460 Cell Growth and Differentiation (3) is a unique course that uses the primary literature to teach significant content in advanced cell biology while simultaneously exposing students to the scientific craft of experimental design and analysis. In addition to exploring historical and current cell biology research articles, students will develop two vital scientific skills; critical thinking as applied to experimental data and creative thinking about solving unresolved questions in cell biology. In this course students will read from journals to explore questions about cell biology and how cell biologists decipher cell functions. Instead of a general survey of cell biology, we delve into specific issues, often looking at "classic" papers describing how a specific phenomenon was first investigated to place current questions in context before progressing to the latest publications exploring how innovative techniques have been applied to deciphering cell function. The course is divided into units, each of which emphasizes content in a different area. Actual content may vary from year to year as the course is updated to reflect progress in a field of research. We have previously explored the general areas of cell membrane dynamics, intracellular protein trafficking, cell cycle regulation, cell signaling pathways and cancer cell biology. Finally, the course ends with a unit on stem cells and therapeutic cloning technology. A portion of the final unit is also devoted to discussing the ethical implications of stem cell research with an emphasis on how to make personal decisions about how our society should approach these issues. Reading guides are provided for each assignment to help students find and understand important points in reading assignments. Class periods are devoted to explanations and instructor-led discussions about the readings with an emphasis on understanding the questions, the methods used to approach the questions, the experimental results and the interpretations of the results. Furthermore, periodic class periods are dedicated to experimental approach exercises where students work in groups to practice posing new questions as suggested by our readings and proposing experiments to answer these questions. These skills are vital part of what cell biologists do daily, and these exercises provide practice in thinking like a scientist. Students have previously reported that by taking this course they acquired the ability to read and understand the primary literature and have gained an in-depth understanding about how to use various experimental techniques.

The second unit includes the theory and practice of biological spectroscopy with emphasis on visible, infrared, circular dichroism, optical rotary dispersion, Raman, resonance Raman, nuclear magnetic resonance, electron paramagnetic resonance, Mossbauer, surface plasmon resonance, electron-nuclear double resonance, and electron spin echo spectroscopy of macromolecules. The lectures are designed to introduce a particular topic, to derive relevant equations, to supplement reading material with practical examples, and to clarify points in assigned problem sets. Two guest lectures by experts in the field will provide up-to-date information on mass spectroscopy and Mossbauer spectroscopy, and two site-visits, one to the mass spectrometry core facility and the other to the magnetic resonance core facility, will provide hands-on experience. Problem sets are not collected or graded; rather, answers are handed out in the following class period. This method provides the ability to collaborate with others on solving problems and to self-check work.
BMB 480 / MICRB 480 Cancer Development and Progression (3) explores how cancer initiates and progresses with a focus on the interactions between tumor cells and normal tissues in the body. The goal of the course is to build fundamental knowledge of the mechanisms that drive cancer, and the current advances and challenges in cancer treatment. Genetic, biochemical, mechanical, and metabolic aspects of cancer will all be discussed along with relevant experimental techniques. RNA and DNA viruses that cause cancer will be highlighted as agents leading to the discovery of oncogene and tumor suppressor signaling pathways, and as ongoing contributors to cancer-related death. Significant attention will be given to the role of the immune system in cancer development, prevention, and treatment. By understanding mechanisms leading to the disruption of signaling pathways in cancer, students will develop a framework of how hallmark features of cancer arise and what corresponding therapeutic strategies have been developed to target them. Students are expected to participate in lectures and take part in discussion and analysis of scientific literature. This course applies core concepts from genetics, biochemistry, and cell biology to the study of cancer and provides a useful foundation for students interested in pursuing related graduate research or medical studie

Modern DNA sequencing technologies have transformed molecular biology into a data science. Sequencing machines can now read hundreds of millions of DNA sequence fragments in a few hours and at low cost. These technologies not only enable affordable sequencing of individual genomes (human or any other species); they also allow us to investigate numerous ways in which the genome performs its biological functions in different cell types and how mutations in genomes give rise to various phenotypes. However, given the volume of data and the noisy nature of biological measurements and signals, we require intelligent and efficient computational algorithms to make sense of genomic datasets. The discipline of bioinformatics and computational biology aims to meet this need. This course focuses on understanding and applying the computational methods and algorithms that are used to analyze genomic data, in particular the large datasets arising from high-throughput DNA sequencing technologies. During the course, we will focus on several application areas in genomics that require computational analyses. These topics will be organized around three main themes: - Genomes: comparing DNA and protein sequences; locating sequences on the genome; assembling genomes. - Evolution: reconstructing evolutionary relationships; personal genomics; detecting disease-associated genome variations. - Function: understanding biochemical activities using functional genomics; discovering functional elements in genome sequences; characterizing regulatory relationships between genes. For each of the genomics topics listed above, we will focus on understanding the computational algorithms that are used to analyze data. Such algorithms may include dynamic programming (sequence alignment), graph algorithms (assembly), clustering methods (phylogenetics & metagenomics), and machine-learning approaches such as Expectation Maximization, Gibbs sampling, and Hidden Markov Models (various applications in discovering functional genomic elements). Students will also develop practical bioinformatics analysis skills throughout the course. Each bioinformatics topic will be accompanied by practical exercises. Students will also work in teams to research and develop a project that applies computational methods to a genomics-related problem.
Biochemical, genetic and evolutionary approaches to comprehensive discovery of functional DNA segments in genomes, including genes and regulatory sequences. BMB 484 Functional Genomics (3) What in your genomic DNA makes you different from chimpanzees, mice or flies? What sequences in your DNA make it more or less likely that you will develop diabetes or cancer? These are questions of widespread interest, answers to which could play major roles in personalized medicine and in understanding our place in the biosphere. Modern genomic analysis uses powerful technologies and generates massive amounts of data, which are yielding exciting insights into answering these questions. One hallmark of genomic research is that data are released rapidly along with tools for browsing and analyzing it. Thus not only can you learn the major results by reading papers, but you can examine the underlying data and do your own analyses. Discovery is no longer the exclusive domain of the data producers - you can join in!This course will introduce students to ongoing research aimed at identifying functional regions in genomes and encourage them to use web-based bioinformatics tools for exploring the genomic and epigenetic data. Students will develop creative projects that address issues in functional genomics of high interest to them.The course has two phases, the first on the basics of genomics (sequencing, alignment, assembly, resources), and the second on the search for functional elements in genomes. The course will explore ways to find:- Protein-coding genes within genomes- Transcribed regions: How much of the genome is transcribed? Which transcribed regions do not code for proteins? What roles do they play in the cell (regulatory and enzymatic)?- Evolutionary signatures of function: How can you use genome comparisons between species to estimate the amount of functional sequence - and to identify it?- Non-genic functional sequences: How do you map epigenetic features associated with gene regulation, such as histone modifications, DNase hypersensitive sites, and transcription factor occupancy?- Function by phenotype: Given the ability of genetic association to find loci that contribute to complex traits, such as disease susceptibility, how does functional genomics aid in finding basis of these traits?
The purpose of this course is to introduce students to the field of Human Genomics and Biomedical Informatics, in particular in the context of genetic architecture of complex human diseases and traits. The field of Human Genomics has experienced a massive explosion in data generation technologies, new discoveries, and increasing popularity in many scientific fields. This course will cover the molecular, statistical, population, and analytical aspects of modern human genomics and translational aspects of this field in biomedical informatics. Current methods to uncover the complex underpinnings of disease including methods to explore gene-gene and gene-environment interactions and data integration will also be covered.
