TP53 R249S mutation in hepatic organoids captures the predisposing cancer risk

open access: yesHepatology, EarlyView., 2022
The systematic approach in elucidating the gain‐of‐function (GOF) roles of TP53 mutations in early liver carcinogenesis. Unique downstream targets of TP53 L3 mutations were identified from chormatin immunoprecipitation sequencing in HCC cell lines, followed by a series of validation assays to substantiate the exclusive transcriptional regulations ...

Analysis of the SOS response of Vibrio and other bacteria with multiple chromosomes

open access: yesBMC Genomics, 2012
Background The SOS response is a well-known regulatory network present in most bacteria and aimed at addressing DNA damage. It has also been linked extensively to stress-induced mutagenesis, virulence and the emergence and dissemination of antibiotic ...

Non‐Respiratory Extracellular Electron Transfer Competes with Nitrogenase for Electrons in Rhodopseudomonas Palustris

open access: yesAdvanced Science, EarlyView.
This study develops a photosynthetic bioelectrochemical nitrogen fixation system for simultaneous nitrogen fixation and current generation using Rhodopseudomonas palustris. Notably, extracellular electron transfer (EET) serves as a redox balancing strategy, suppressing nitrogen fixation by competing with nitrogenase for electrons.

Fast pH‐Driven Solubilization Method of Realgar (As4S4) to Reduce the Toxicity of Arsenic [As(III)] for Medicinal Purposes

open access: yesAdvanced Science, EarlyView.
Arsenic trioxide transformed acute promyelocytic leukemia therapy and shows promise against HIV. A new method to solubilize the mineral realgar produces different arsenic species depleting the main arsenic target, nuclear PML protein, and retaining effects on leukemic and HIV reservoir cells, while minimizing off‐target damage.

Self‐Propelled In Situ Polymerized Nanoparticles Activating the STING Pathway for Enhanced Bladder Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
A self‐propelled nanomedicine delivery system forms DMCU nanoparticles in the bladder via in situ polymerization of dopamine hydrochloride, Mn2+, cGAMP, and urease. The urease‐driven propulsion enhances retention and drug delivery. These nanoparticles activate the STING pathway, stimulating dendritic cells and T cells to boost anti‐bladder cancer ...

Targeted Intervention Strategies for Maternal–Offspring Transmission of Christensenellaceae in Pigs via a Deep Learning Model

open access: yesAdvanced Science, EarlyView.
This study deciphers maternal‐driven microbial transmission in pigs using a deep learning model (maternal–offspring microbial transmission model), identifying Christensenellaceae R‐7 group as a key transmitted taxon. Filtered galacto‐oligosaccharides‐targeted Christensenellaceae R‐7 group alters offspring microbial functions via maternal ...

Genetic and cytological analyses reveal the recombination landscape of a partially differentiated plant sex chromosome in kiwifruit

open access: yesBMC Plant Biology, 2019
Background Angiosperm sex chromosomes, where present, are generally recently evolved. The key step in initiating the development of sex chromosomes from autosomes is the establishment of a sex-determining locus within a region of non-recombination.

Neuronal FGF13 Inhibits Mitochondria‐Derived Damage Signals to Prevent Neuroinflammation and Neurodegeneration in a Mouse Model of Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
This study elucidates a novel role of FGF13 in manipulating neuronal fate via mitochondrial transfer. FGF13 is identified as a mitochondria‐stabilizing protein by interacting with mitochondrial proteins. Under stress, the decrease of neuronal FGF13 fails to retain mitochondria within the cytoplasm, leading to the release of damaged mitochondria to ...
