A closer alliance between computational and experimental researchers is needed to make progress towards one of biology's most challenging goals, understanding how epigenetic marks contribute to regulation of gene expression. This emerged from a recent workshop organised by the European Science Foundation (ESF), "Computational Approaches to the Role of Epigenetic ...

Researchers at Boston College have developed the first laboratory mouse model that mimics cancer's spread through the human body. Using their novel cell line, the team discovered one of the body's primary defensive cells plays a role in cancer's attack.The development of a new animal model - a line of ...

Although the pharmaceutical industry has dedicated enormous research efforts over the last 50 years to identify new targets and develop new active ingredients, these efforts have met with limited success. One of the main reasons for the failure of many molecules is because the studies have focused, almost exclusively, ...
