Course code :


Course name :

Epigenetics : from biological phenomena to molecular mechanisms

Coordinators :

Vincent Colot and Barbara Despres



Keywords :

gene, genome, mendelian and non-mendelian inheritance, DNA and histones modifications, heterochromatin, euchromatin, transposons, RNA interference, epimutations. Techniques : ChIP-seq, DNA bisulfite treatment and sequencing, sRNA-profiling, Chromosome conformation capture.

Prerequisites for the course :

Genetics/epigenetics course and molecular biology.

Course objectives and description :

The objective of this course is to discover the paradigms of epigenetics : from the epigenetic phenomenons to the molecular mechanisms. Topics include maintenance of chromatin states, role of small RNAs and long non-coding RNAs in epigenetic regulation and inheritance, parental imprinting, X-inactivation in mammals, paramutation, transgenerational epigenetic inheritance in plants and prions as epigenetic phenomenon. This course is organized through seminars and analysis of articles.

Assessment / evaluation :

Written exam and oral presentation of articles.

Course material (hand-outs, online presentation available, …) :

Research papers provided as pdf assignments for oral presentation ; pdf presentations of talks available online.
