MetabolomicsIdentification and validation of poly-metabolite scores for diets high in ultra-processed food: An observational study and post-hoc randomized controlled crossover-feeding trial.

BACKGOUND: Ultra-processed food (UPF) accounts for a majority of calories consumed in the United States, but the impact on human health remains unclear. We aimed to identify poly-metabolite scores in blood and urine that are predictive of UPF intake.

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...

TranscriptomicsPoly(A)-tail profiling reveals an embryonic switch in translational control
Poly(A) tails enhance the stability and translation of most eukaryotic messenger RNAs, but difficulties in globally measuring poly(A)-tail lengths have impeded greater understanding of poly(A)-tail function. Here we describe poly(A)-tail length profiling by sequencing (PAL-seq) and apply it to measu...

TranscriptomicsGenome-wide analysis of PAPS1-dependent polyadenylation identifies novel roles for functionally specialized poly(A) polymerases in Arabidopsis thaliana
The poly(A) tail at 3' ends of eukaryotic mRNAs promotes their nuclear export, stability and translational efficiency, and changes in its length can strongly impact gene expression. The Arabidopsis thaliana genome encodes three canonical nuclear poly(A) polymerases, PAPS1, PAPS2 and PAPS4. As shown ...

ProteomicsMass spectrometry approach to identify mitochondrial poly(A) RNA interacting proteins
To identify mitochondrial RNA-interacting proteins, we developed three related mass spectrometry based methods. In the first method, called mitochondrial crosslinking (MXL), mitochondria of 4-thiouridine labelled cells were isolated, exposed to UV-light and poly(A) RNA was isolated. In the second me...

MetabolomicsDiel metabolomics analysis of a hot spring chlorophototrophic microbial mat leads to new hypotheses of community member metabolisms
Dynamic environmental factors such as light, nutrients, salt, and temperature continuously affect chlorophototrophic microbial mats, requiring adaptive and acclimative responses to stabilize composition and function. Quantitative metabolomics analysis can provide insights into metabolite dynamics fo...

MetabolomicsImidazole ketone erastin induces ferroptosis and slows tumor growth in a mouse lymphoma model
Ferroptosis is a form of regulated cell death that can be induced by inhibition of the cystine-glutamate antiporter, system xc-. Among the existing system xc- inhibitors, imidazole ketone erastin (IKE) is a potent, metabolically stable inhibitor of system xc- and inducer of ferroptosis potentially s...
