ProteomicsImproved SILAC Method for Double Labeling of Bacterial Proteome
Stable isotope labeling with amino acids in cell culture (SILAC) is a robust proteomics method with the advantages of reproducibility and easy handling. This method is popular for the analysis of mammalian cells. However, amino acid conversion in bacteria decreases the labeling efficiency and quanti...

TranscriptomicsComparison of Labeling Methods for gene expression analysis on the NimbleGen platform
Comparison of ds-cDNA, Indirect and Direct Random Labeling Methods for gene expression analysis on the NimbleGen platform. Expression profiles from artemisinic acid-producing S. cerevisiae strain EPY330 and non-producing strain EPY338 are compared for each labeling method tested. The labeling metho...

GenomicsSelective chemical labeling reveals intragenic enrichment of 5-hydroxymethylcytosine in mouse cerebellum
5-Methylcytosine (5-mC) is an important DNA modification found in eukaryotes that impacts gene regulation and disease pathogenesis. Recently, 5-hydroxymethylcytosine (5-hmC), another form of DNA modification, has been identified in substantial amounts in certain mammalian cell types; however, its ro...

TranscriptomicsA Role for Small RNAs in DNA Double-Strand Break Repair
Here we identify a novel class of small RNAs that are ~21-nucleotide in length and are produced from the sequences in the vicinity of DNA double strand break (DSB) sites in Arabidopsis and humans. We named them diRNAs for DSB-induced small RNAs. In Arabidopsis, the biogenesis of diRNAs requires the ...

TranscriptomicsMonitoring Homology Search during DNA Double-Strand Break Repair in vivo
Homologous recombination (HR) is crucial for genetic exchange, accurate repair of DNA double-strand breaks and pivotal for genome integrity. HR uses homologous sequences for repair, but how homology search, the exploration of the genome for homologous DNA sequences, is conducted in the nucleus remai...

TranscriptomicsMeiotic DNA double strand breaks in the yeast Saccaromyces cerevisiae
DNA double-strand breaks (DSBs) initiate meiotic recombination. Past DSB-mapping studies have used rad50S or sae2? mutants, which are defective in break processing, to accumulate DSBs, and report large (= 50 kb) “DSB-hot” regions that are separated by “DSB-cold” domains of similar size. Substantial ...

ProteomicsQuantitative proteomic comparison between wild type Col and acinus-2 pinin-1 mutant using 15N metabolic labeling
ACINUS and PININ genes regulate transcription and alternative splicing (Bi et al., 2021) and we hypothesize that some proteins should have altered expression in the double mutant. Therefore, MS experiments were designed to identify these altered proteins on a global scale using 15N metabolic labeli...
