Week 1 - Introduction to Epigenetic Control

An introduction to and definition of epigenetic control of gene expression, and its importance in normal development. We will learn what chromatin is, and how its composition and packaging can alter gene expression. We’ll also discuss the best-characterised epigenetic modification, DNA methylation, and how it is not only implicated in regulating gene expression, but also in maintaining genome stability. ...

Week 2 - Epigenetic Modifications and Organisation of the Nucleus

We’ll discuss the molecular mechanisms for regulating gene expression in some detail, from how the DNA is packaged at a local level, right up to how the chromatin is positioned within the nucleus. We’ll learn about the chromatin modifications implicated in gene silencing and activation, the role of non-coding RNA, and higher order chromatin structures. This week will provide you with a good understanding of the basic mechanisms that will help you understand the processes we discuss throughout the rest of the course. ...

Week 3 - Dosage Compensation

X chromosome inactivation is a really well-characterised epigenetic process that is now used as a model system to study epigenetic processes that are relevant more broadly. This is because it uses many epigenetic mechanisms, at many levels, to achieve really stable silencing of a whole chromosome. We’ll learn about this process and how it occurs in a mouse in great detail, which will greatly add to the mechanistic understanding gained in week two. We will then briefly discuss alternate mechanisms for dosage compensation that occur in other organisms. ...

Week 4 - Genomic Imprinting and Epigenetic Reprogramming

We’ll learn about the two important periods during development for the erasure and resetting of the epigenome. There are two well-characterised features that are treated differently during epigenetic reprogramming; imprinted genes and repeats. We’ll learn about mechanisms for genomic imprinting, and study three examples in more depth....

This was an excellent course. All the material was well presented and the explanation of the sometimes complex subject matter was clear and understandable. Thank you for an great learning experience.

创建者 DSAug 25th 2018

This is an excellent course that introduces you to fundamental knowledge of several hot topics in the field of epigenetics. Dr. Blewitt herself studies X inactivation, and I learned so much!
