Co-expressed genes are often expected to be functionally related and many bioinformatics approaches based on co-expression have been developed to infer their biological role. However, such annotations may be unreliable, whereas the evolutionary conservation of gene co-expression among species may...
Sphingolipids are key components of eukaryotic plasma membranes that are involved in many functions, including the formation signal transduction complexes. In addition, these lipid species and their catabolites function as secondary signalling molecules in, amongst other processes, apoptosis. The...
