GenomicsWhole-genome nucleosome mapping in meiotic diploid S. cerevisiae
We determined nucleosome positions throughout the genome in diploid S. cerevisiae undergoing early stages of synchronous meiosis. This study sought to assess if systematic reorganization of nucleosomes occurs during meiotic prophase at or near sites of DNA double strand break formation. Six samples ...

GenomicsGenome-wide mapping of meiotic double-strand breaks by sequencing Spo11 oligos.
The nonrandom distribution of meiotic recombination shapes patterns of inheritance and genome evolution, but chromosomal features governing this distribution are poorly understood. Formation of the DNA double-strand breaks (DSBs) that initiate recombination results in accumulation of Spo11 protei...

TranscriptomicsBRCT phosphoprotein recognition, but not E3 ligase activity, is essential for BRCA1 tumor suppression
It has been recognized that BRCA1, in the form of the BRCA1/BARD1 heterodimer, acting as an ubiquitin E3 ligase offered a possible mechanism to explain its pleiotrophic nature of BRCA1 activity. Our observation that mice lacking BRCA1 enzymatic activity are viable apart from male sterility was unex...
