While the human genome sequence has transformed our understanding of human biology, it isn’t just the sequence of your DNA that matters, but also how you use it! How are some genes activated and others are silenced? How is this controlled? The answer is epigenetics.

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.

por MM1 de Out de 2018
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.
por GK19 de Mai de 2020
This course was new to me. All the concepts were explained in a very simplified manner. I am very happy to have done this course and find it a very interesting field to take upm in my future career.
por CY9 de Mai de 2020
Very clear explanation of the concepts and details. I would say it is a difficult course for students from engineering background, even having some bioinfomatics and oncology courses background
por DS24 de Ago de 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!
Perguntas Frequentes – FAQ
Quando terei acesso às palestras e às tarefas?
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
- The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
- The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
O que recebo ao adquirir o Certificado?
Quando você adquire o Certificado, ganha acesso a todo o material do curso, incluindo avaliações com nota atribuída. Após concluir o curso, seu Certificado eletrônico será adicionado à sua página de Participações e você poderá imprimi-lo ou adicioná-lo ao seu perfil no LinkedIn. Se quiser apenas ler e assistir o conteúdo do curso, você poderá frequentá-lo como ouvinte sem custo.
Qual é a política de reembolso?
Você poderá pedir reembolso total até duas semanas após a data do pagamento, ou (para cursos recém-iniciados) até duas semanas após o início da primeira sessão do curso, o que ocorrer por último. Você não poderá receber reembolso após obter o Certificado de Curso, mesmo que tenha completado o curso dentro do período de duas semanas. Veja nossa política para o reembolso total.
Existe algum auxílio financeiro disponível?
Sim, a Coursera oferece auxílio financeiro aos alunos que não podem pagar a taxa. Faça a solicitação clicando no link Auxílio financeiro, abaixo do botão "Inscreva-se" à esquerda. Você será solicitado a preencher um formulário e será notificado se for aprovado. Saiba mais.
Ganharei créditos universitários por concluir o curso?
Este curso não oferece créditos universitários, mas algumas universidades podem aceitar certificados de cursos que podem ser convertidos em créditos. Entre em contato com sua instituição para saber mais. Com os cursos on-line e os certificados Mastertrack™ do Coursera, é possível ganhar créditos universitários.
