330029 VO Nutrition and Gene Regulation (2018W)

Objectives

The students will understand
- the basic principles of gene regulation in humans,
- the role of transcription factors , their activation and regulation,
- the methods of nutrigenomics,
- how specific nutrients affect gene regulation and signal transduction as well as
- the specific transcription factors involved in these processes,
- the potential impact of these events on health and disease

Contents

Principles of gene regulation:
- Transcriptional regulation
- Post-transcriptional regulation
- Modifications of chromatin structure
- DNA sequence elements with regulatory characteristics

Transcription factors:
- DNA-binding
