MetabolomicsExcoriation Disorder Is Characterized by Systemic Glutamatergic Dysfunction

Excoriation disorder (ED), also known as neurotic excoriations, is a psychocutaneous disorder characterized by repetitive, compulsive picking of the skin leading to secondary tissue damage. ED carries an estimated prevalence of 1.4%, and is associated with significant social dysfunction, as patie...

TranscriptomicsJeB001: Elucidation of the distal convoluted tubule transcriptome identified new candidate players in magnesium balance
The distal convoluted tubule (DCT) plays a key role in the fine-tuning of renal Mg2+ reabsorption. In recent years, hereditary magnesium (Mg2+) transport disorders have helped to identify important players in DCT Mg2+ homeostasis. Here, we report the Mg2+-sensitive transcriptional expression of the ...

TranscriptomicsTranscription Dynamically Patterns the Meiotic Chromosome-Axis Interface [ChIP-chip]
Meiotic chromosomes are highly compacted yet remain transcriptionally active. To understand how chromosome folding accommodates transcription, we investigated the assembly of the axial element, the proteinaceous structure that compacts meiotic chromosomes and promotes recombination and fertility. We...

TranscriptomicsSeparation of DNA replication from the assembly of break-competent meiotic chromosomes
The meiotic cell division reduces the chromosome number from diploid to haploid to form gametes for sexual reproduction. Although much progress has been made in understanding meiotic recombination and the two meiotic divisions, the processes leading up to recombination, including the prolonged pre-m...

TranscriptomicsDSB formation in replication compromised cells
DSBs were mapped genome-wide by ssDNA enrichment in cdc6-mn replication comprimsied strains. We mapped DSB sites by detecting DSB-associated ssDNA enrichment on microarrays. To test the role of DNA replication in DSB formation, we mapped ssDNA in a cdc6-mn replication depleted strain. ssDNA was isol...

TranscriptomicsMapping of meiotic double-strand break (DSB) sites and DSB factor association near repetitive DNA elements in S. cerevisiae
DNA double strand breaks (DSBs) in repetitive sequences are a potent source of genomic instability, due to the possibility of non-allelic homologous recombination (NAHR). Repetitive sequences are especially at risk during meiosis, when numerous programmed DSBs are introduced into the genome to initi...

TranscriptomicsssDNA mapping in dmc1 strains
ssDNA enrichment was used to map and compare DSB hotspots in dmc1, pch2 dmc1, sir2 dmc1, orc1-161 dmc1, dmc1 rdnadelete and dmc1 chr2:12 translocation strains. 6 samples, 2 replicates each. Averaged data is available as a supplementary file on the Series record (below).

TranscriptomicsTranscription profiling of Lotus japonicus grown under different salt acclimation regimes
Model legume Lotus japonicus was subjected to non-lethal long-term salinity and profiled at the transcriptomic level. Three independent experiments were performed, testing two experimental designs: a traditional gradual acclimation following a step-wise increase of salt concentration and an initial ...
