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...

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.

METHODS AND FIN...

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...

MetabolomicsMechanisms of poly(butylene adipate-co-terephthalate) microplastic degradation in agricultural soil: Insights from the soybean rhizosphere

The increasing application of biodegradable mulch films in agriculture has raised concerns regarding the potential persistence of biodegradable microplastics (BMPs) in soil and their subsequent ecological impacts. Although these materials are designed to mineralize, their actual rates of breakdow...

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 ...

TranscriptomicsSaccharomyces cerevisiae 3' poly(A) site mapping
The use of alternative polyadenylation sites is common and affects the post-transcriptional fate of mRNA, including its stability, localization, and translation. Here we present a method for genome-wide and strand-specific mapping of poly(A) sites and quantification of RNA levels at unprecedented ef...

TranscriptomicsPoly(A) tail length profiling of mRNAs from fission yeast
To obtain global data on polyadenylation of mRNAs, we fractionated the mRNAs according to their poly(A) tail length using a poly-U sepharose column followed by differential elution at five temperatures. Five mRNA fractions with distinct ranges of poly(A) tail length were then hybridized to microarr...
