MetabolomicsThe Poly (ADP-Ribose) Polymerase inhibitor Veliparib and Radiation Cause Significant Cell Line Dependent Metabolic Changes in Breast Cancer Cells
Breast tumors are characterized into different subtypes based on their surface marker expression, which affects their prognosis and treatment. For example, triple negative breast cancer cells (ER-/PR-/Her2-) show reduced susceptibility towards radiotherapy and chemotherapeutic agents. Poly (ADP-ribo...

MetabolomicsMetabolic responses induced by DNA damage and poly (ADP-ribose) polymerase (PARP) inhibition in MCF-7 cells
Genomic instability is one of the hallmarks of cancer. Several chemotherapeutic drugs and radiotherapy induce DNA damage to prevent cancer cell replication. Cells in turn activate different DNA damage response (DDR) pathways to either repair the damage or induce cell death. These DDR pathways also e...

TranscriptomicsTime course transcriptome of Lactobacillus oligofermentans LMG 22743 during the growth on glucose, ribose and xylose
L. oligofermentans was grown microaerobically on modified (without malic acid, cellulose and bromocresol green) MLD medium (Cavin JF et al., Appl Environ Microbiol 1989), containing either glucose, ribose or xylose as a sole carbon source (50mM) in three replicates. Samples were taken at three time ...

TranscriptomicsRibose utilization by the human commensal Bifidobacterium breve UCC2003
Growth of B. breve UCC2003 on ribose leads to the transcriptional induction of the rbsACBDK gene cluster. Generation and phenotypic analysis of an rbsA insertion mutant established that the rbs gene cluster is essential for ribose utilization, and that its transcription is likely regulated by a LacI...

TranscriptomicsRiboMeth-seq: High-throughput mapping of ribose methylations in RNA at single-nucleotide resolution
The major information-carrying macromolecules in the cell, DNA, RNA, and protein, carry an additional layer of information on top of their sequence in the form of modifications of residues. The modifications provide additional functional groups and impact the structure and function of the molecules....

ProteomicsCellular ADP-ribosylome characterization with HCD and EThcD
Protein ADP-ribosylation is a post-translational modification involved in important physiological and pathological processes. Here, we present an optimized method using the Orbitrap Fusion Tribrid mass spectrometer, which drastically improves the overall ADP-ribosylation site localization score and ...

TranscriptomicsTranscription profiling by array of Lactobacillus sakei strains grown on ribose or glucose to study ribose catabolism
We used a whole-genome microarray based on the sequenced strain Lactobacillus sakei 23K to study ribose catabolism in three Lactobacillus sakei strains by screening for differentially expressed genes when grown on ribose compared to glucose

ProteomicsAn azidoribose probe to track ketoamine adducts in histone ribose glycation (293T nuclei - LFQ)
Reactive cellular metabolites can modify macromolecules and form adducts known as non-enzymatic covalent modifications (NECMs). Dissecting the mechanisms, regulation and consequences of NECMs, such as glycation, has been challenging due to the complex and often ambiguous nature of the adducts formed...

MetabolomicsStable isotope resolved analysis of HUVEC Cells under normaxia and hypoxia
In order to analyze HUVECs under normoxia and hypoxia, cells were initially deprived of excess nutrients and hormones by maintaining them overnight in a restricted medium with only 2% fetal bovine serum, and incubated for 40 hours in the presence of the tracer [1,2-13C2]-glucose until sample collect...

TranscriptomicsRNAi of human MCF7 cells knocked down for PARP-1 or PARGs
Poly(ADP-ribose) polymerase-1 (PARP-1) and poly(ADP-ribose) glycohydrolase (PARG) are enzymes that modify target proteins in the nucleus by the addition and removal, respectively, of ADP-ribose polymers. Although a role for PARP-1 in gene regulation has been well established, the role of PARG is le...
