Two studies from the labs of Steven McCarroll and Monica Colaiacovo provide new insights into how meiotic crossover formation is regulated to avoid aneuploidies, a cause for infertility, miscarriages and conditions such as Down syndrome.

Link to Harvard Medical NewsOur new study in bioRχiv about FANC pathway in DNA repair and histone modification.
The histone demethylase LSD1 was originally discovered as removing methyl groups from di- and monomethylated histone H3 lysine 4 (H3K4me2/1), and several studies suggest it plays roles in meiosis as well as epigenetic sterility given that in its absence there is evidence of a progressive accumulation of H3K4me2 through generations. In addition to transgenerational sterility, growing evidence for the importance of histone methylation in the regulation of DNA damage repair has attracted more attention to the field in recent years. However, we are still far from understanding the mechanisms by which histone methylation is involved in DNA damage repair and only a few studies have been focused on the roles of histone demethylases in germline maintenance. Here, we show that the histone demethylase LSD1/CeSPR-5 is interacting with the Fanconi Anemia (FA) protein FANCM/CeFNCM-1 based on biochemical, cytological and genetic analyses. LSD1/CeSPR-5 is required for replication stress-induced S-phase checkpoint activation and its absence suppresses the embryonic lethality and larval arrest observed in fncm-1 mutants. FANCM/CeFNCM-1 re-localizes upon hydroxyurea exposure and co-localizes with FANCD2/CeFCD-2 and LSD1/CeSPR-5 suggesting coordination between this histone demethylase and FA components to resolve replication stress. Surprisingly, the FA pathway is required for H3K4me2 maintenance regardless of the presence of replication stress. Our study reveals a connection between Fanconi Anemia and epigenetic maintenance, therefore providing new mechanistic insight into the regulation of histone methylation in DNA repair.

PLOS Genetics publishes human studies, as well as research on model organisms—from mice and flies, to plants and bacteria. Their emphasis is on studies of broad interest that provide significant insight into a biological process or processes. Topics include (but are not limited to) gene discovery and function, population genetics, genome projects, comparative and functional genomics, medical genetics, disease biology, evolution, gene expression, complex traits, chromosome biology, and epigenetics.
