Course Description

This Molecular Cell Biology course provides a comprehensive overview of the techniques, experimental design, and interpretation of results performed by scientists past and present, showing how important discoveries from diverse disciplines led to our present understanding of the cell biology that forms the basis of modern nutritional sciences. The course starts with basic information from chemistry, biochemistry, and biology, and demonstrates how this information was integrated into the foundations of our understanding of basic biological process and genetic mechanisms of cell and molecular biology. This leads into a discussion of cell organization, biochemistry, and intermediary metabolism, and how these cellular processes are integrated into the systems essential for life, such as transport of ions and small molecules across cell membranes. Molecular genetic techniques and emerging technology in genomics and proteomics is discussed in the context of their application in studying the details of transcriptional and post-transcriptional control of gene expression as well as nuclear transport.

The course emphasizes interactions and processes at the cell surface through examples from the emerging field of cell signaling: How signals are received at the cell surface, amplification by signal transduction pathways leading to alteration in gene activity, and the integration of multiple signals and external stimuli to control specific genes that underlie cellular homeostasis, adaptation to environmental change, and pathogenesis. These phenomena are then discussed in the context of basic mechanisms of cell cycle and cell-growth control, including lineage specification in early development and cell-type specification in yeast. Finally, tissue-specific development and its control in higher eukaryotes is discussed in the context of cancer, infection, and aging. Every participant in the course leads at least one session, and each session is attended by at least three preceptors. Extensive discussion is encouraged among all participants, with preceptors and participants providing outside information and perspectives.

Strong emphasis is placed on various aspects of cell biology relate to:
i) Digestive and absorptive function of the intestine,
ii) Regulation of gene expression by nutrient
iii) Micro-nutrient in transcriptional and posttranscriptional control
iv) Mechanism macro-nutrient and micro-nutrient malabsorption and human pathology
v) Cell biology of the mucosal immunology of the digestive tract
vi) The development of mucosal immunology in pathogen induced damage and infection
vii) Cell secretion during diarrhea
viii) Strategies employed by enteric pathogen invasion of intestine
ix) Mechanism of nutrient absorption in the development of obesity and diabetes
x) Cell-cell and paracrine communication of the intestine during infection, and inflammatory response
xi) Nutrition in cancer
