The Epigenetics of Human Sperm Cells (Sarah Kimmins)

In this episode of the Epigenetics Podcast, we caught up with Sarah Kimmins from Université de Montreal to talk about her work on the epigenetics of human sperm cells.

The focus of Sarah Kimmins and her lab is how sperm and offspring health is impacted by the father's environment. The core of this is the sperm epigenome, which has been implicated in complex diseases such as infertility, cancer, diabetes, schizophrenia and autism. The Kimmins lab is interested which players play a role in this and came across the Histone post-translational modification H3K4me3. In this interview we talk about how the father's life choices can impact offspring health, which can also be inherited transgenerationally and how this can be used to develop intervention strategies to improve child and adult health.
