Atomic mutagenesis of stop codon nucleotides reveals the chemical prerequisites for release factor-mediated peptide release. [PDF]

open access: yes, 2018
Termination of protein synthesis is triggered by the recognition of a stop codon at the ribosomal A site and is mediated by class I release factors (RFs).

Microtubule-directed transport of purine metabolons drives their cytosolic transit to mitochondria

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2018
Significance This study draws on the power of superresolution microscopy to investigate how metabolons behave near different subcellular components. We revealed an interdependent relationship among purinosomes, mitochondria, and microtubules.

CDH1 Orchestrates Anabolic Events to Promote Cell Cycle Initiation

open access: yesAdvanced Science, EarlyView.
Cell proliferation requires the integration of cell cycle and anabolic signals. G1‐phase regulator CDH1 coordinates anabolism through the CDH1‐VHL‐AARS2/HIF1α axis, while CDH1‐accumulated R5P is sensed by TKTL1 to facilitate CDH1 degradation and cell cycle initiation, constituting a CDH1‐centered regulatory circuit.

Emerging Role of Purine Metabolizing Enzymes in Brain Function and Tumors

open access: yesInternational Journal of Molecular Sciences, 2018
The growing evidence of the involvement of purine compounds in signaling, of nucleotide imbalance in tumorigenesis, the discovery of purinosome and its regulation, cast new light on purine metabolism, indicating that well known biochemical pathways may ...

Uric Acid Functions as an Endogenous Modulator of Microglial Function and Amyloid Clearance in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
Higher serum UA levels are associated with reduced AD risk in epidemiological studies. UA enhances microglial phagocytic capacity primarily by restoring CD36 and TREM2 receptor recycling that is impaired by Aβ exposure. Therapeutically, UA supplementation improves cognitive function and reduces neuropathology in AD mouse model by enhancing microglial ...

Metabolomic profiling of macrophages determines the discrete metabolomic signature and metabolomic interactome triggered by polarising immune stimuli [PDF]

open access: yes, 2018
Priming and activating immune stimuli have profound effects on macrophages, however, studies generally evaluate stimuli in isolation rather than in combination.

Hypoxia modulates the purine salvage pathway and decreases red blood cell and supernatant levels of hypoxanthine during refrigerated storage

open access: yesHaematologica, 2017
Hypoxanthine catabolism in vivo is potentially dangerous as it fuels production of urate and, most importantly, hydrogen peroxide. However, it is unclear whether accumulation of intracellular and supernatant hypoxanthine in stored red blood cell units is

Predicting MammaPrint Recurrence Risk from Breast Cancer Pathological Images Using a Weakly Supervised Transformer

open access: yesAdvanced Science, EarlyView.
This study presents CPMP, a weakly supervised transformer model that predicts MammaPrint recurrence risk directly from routine histopathological images of early‐stage HR+/HER2− breast cancer patients. CPMP enables spatial heatmap visualization, analysis of cellular‐level interaction patterns, and an in‐depth characterization of morphological phenotypes
