SPROUTS_DB: An Implemented Database of Contaminants for Extracellular Vesicle Proteomics Studies

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Current proteomics techniques allow rapid identification and quantification of proteins within any given biological source. However, LC–MS/MS proteomics is vulnerable to laboratory and sample‐associated contaminants. Therefore, accurate identification and annotation of such contaminants is crucial for development of reliable databases ...

Differential expression of PHGDH in pancreatic cancer.

open access: yes, 2023
Cancer is a leading cause of death and pancreatic cancer is among the most lethal cancers (1, 2). We mined published microarray datasets (3, 4) to determine in an unbiased fashion and at the level of the transcriptome genes most differentially expressed in the primary tumors of patients with pancreatic cancer, pancreatic adenocarcinoma (PDAC).

Network rewiring is an important mechanism of gene essentiality change. [PDF]

open access: yes, 2012
Gene essentiality changes are crucial for organismal evolution. However, it is unclear how essentiality of orthologs varies across species. We investigated the underlying mechanism of gene essentiality changes between yeast and mouse based on the ...

Branched‐Chain Amino and Keto Acids Reduce Hepatocyte Lipid Droplet Size and Number via Distinct Proteomic Pathways

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Branched‐chain amino acids (BCAA) and their corresponding keto acids (BCKA) have been associated with changes in hepatic lipid metabolism and the resulting alterations in intracellular triglyceride concentrations. In this study, we utilized a previously established hepatocyte model to investigate the impact of BCAA and BCKA supplementation on ...

Serine synthesis through PHGDH coordinates nucleotide levels by maintaining central carbon metabolism [PDF]

open access: yesNature Communications, 2018
Abstract Phosphoglycerate dehydrogenase (PHGDH) catalyzes the committed step in de novo serine biosynthesis. Paradoxically, PHGDH and serine synthesis are required in the presence of abundant environmental serine even when serine uptake exceeds the requirements for nucleotide synthesis.

Cell autonomous regulation of herpes and influenza virus infection by the circadian clock. [PDF]

open access: yes, 2016
Viruses are intracellular pathogens that hijack host cell machinery and resources to replicate. Rather than being constant, host physiology is rhythmic, undergoing circadian (∼24 h) oscillations in many virus-relevant pathways, but whether daily rhythms ...

AKR1C3 Binds β‐Trcp to Promote the Degradation of TFRC to Protect Hepatocellular Carcinoma From Ferroptosis

open access: yesCancer Science, EarlyView.
In this study, we show that aldo‐keto reductase family 1 member C3 (AKR1C3), a protein highly expressed in ferroptosis resistant hepatocellular carcinoma cells, acts as an enzyme‐independent scaffold protein by promoting the nuclear export of β‐transducin repeat protein (β‐TrCP) and its binding to transferrin receptor (TFRC) in an enzyme‐independent ...

Serine one-carbon catabolism with formate overflow [PDF]

open access: yes, 2016
Serine catabolism to glycine and a one-carbon unit has been linked to the anabolic requirements of proliferating mammalian cells. However, genome-scale modeling predicts a catabolic role with one-carbon release as formate. We experimentally prove that in

Oxidative Stress and DNA Epigenetic Modifications in Cancer: Mechanisms and Targeted Therapeutics

open access: yesMedComm – Oncology, Volume 5, Issue 2, June 2026.
Reactive oxygen species (ROS) modulate DNA methyltransferases (DNMTs), ten‐eleven translocation family proteins (TETs) and their cofactors, reshaping 5‐methylcytosine (5mC)/5‐hydroxymethylcytosine (5hmC)/5‐formylcytosine (5fC) landscapes and gene expression in cancer cells. In turn, epigenetic control of antioxidant and metabolic pathways feeds back on

A Novel Multimodal LC–MS/MS Panel for the Comprehensive Diagnosis of Neurometabolic Disorders in CSF

open access: yesJournal of Inherited Metabolic Disease, Volume 49, Issue 3, May 2026.
ABSTRACT Metabolic testing of cerebrospinal fluid (CSF) is essential for early diagnosis of neurometabolic disorders. However, the large number of differential diagnoses, the phenotypic variance within a clinical picture, and the disease rarity complicate targeted metabolic diagnostics.
