How we use gene expression to understand disease
This issue of our Science Untangled will focus on how we can use molecular biology to understand more about disease. In iPLACENTA we are interested in the causes of pregnancy pathologies; the juice of the matter is really to understand what's different between a healthy placenta and an unhealthy placenta that will cause the mother to develop a disease, putting both mother and baby in danger.
In this blog we will go through what systems biology means and how we use it in research. Starting with the definition of the terms system, model, followed by an example of network analysis as a systems biology method and the nuanced difference between complex vs complicated. Please ask questions in the comments section if there is anything that you would like explained in more depth!
Systems can be considered on different levels. From organ networks to molecular networks, the individual, or even social networks. The image above was adapted from lectures provided by the Systems Biology and Bioinformatics Department Rostock, Germany and a graph from the Institute of Systems Biology Seattle, USA.
About the blog
Being a PhD student in a European training network is a life-changing adventure. Moving to a new country, carrying out a research project, facing scientific (and cultural) challenges, travelling around Europe and beyond… Those 3 years certainly do bring their part of new - sometimes frightening - but always enriching experiences.
