This Week in PLOS

In PLOS Genetics, Washington State University researchers report on a role for nucleosome structure in ultraviolet light-induced mutational signatures in melanoma. Using a combination of sequencing approaches, the team profiled UV-induced cyclobutane pyrimidine dimer (CPD) mutation patterns and tracked nucleosome positions in almost 200 cutaneous melanoma cases, uncovering mutation density oscillations that appeared to coincide with nucleosome placement.
