BACKGROUND The degradation of DNA represents one of the main issues in the genetic analysis of archeological specimens. In the recent years, a particular kind of post-mortem DNA modification giving rise to nucleotide misincorporation ("miscoding lesions") has been the object of extensive investigations. METHODOLOGY/PRINCIPAL FINDINGS To improve our knowledge regarding the nature and incidence...

Food deprivation can affect performance on difficult cognitive task, such as the delayed nonmatch-to-place T-maze task (DNMT). The importance of food deprivation on maintaining high motivation for DNMT task has been emphasized, but not many studies have investigated the optimal conditions for depriving rodents to maximize performance. Establishing appropriate conditions for food deprivation is ...

We have been studying the evolution and function of DNA methylation in vertebrate animals using three related approaches. The first is to further characterise proteins that bind to methylated DNA. Such proteins can be viewed as 'receptors' of the methyl-CpG 'ligand' that mediate downstream consequences of DNA modification. The second approach involves CpG islands. These patches of non-methylate...
