Cellular DNA Ligase I Is Recruited to Cytoplasmic Vaccinia Virus Factories and Masks the Role of the Vaccinia Ligase in Viral DNA Replication

open access: yes, 2009
SummaryVaccinia virus (VACV) encodes DNA polymerase and additional proteins that enable cytoplasmic replication. We confirmed the ability of VACV DNA ligase mutants to replicate and tested the hypothesis that cellular ligases compensate for loss of viral

Ecological Adaptation Mechanisms Underlying Successful Plant Reproduction

open access: yesAdvanced Science, EarlyView.
During floral induction, various environmental and endogenous signals converge to regulate the florigen protein, which is transported from leaves to the SAM to initiate flowering. Within the SAM, a complex network of receptor kinases and small peptides orchestrates floral development with high spatiotemporal precision.

Cis‐ and Trans‐Regulatory Factors Independently Shape Phenotypic Heterogeneity of Retinitis Pigmentosa

open access: yesAdvanced Science, EarlyView.
A zebrafish model carrying an identical human RHO S334X allele reveals two independent genetic layers shaping retinitis pigmentosa (RP) severity: a protective 3‐bp cis‐regulatory insertion that attenuates transgene expression, and a dominant trans‐acting modifier that restores a severe phenotype.

Liquid Metal Nanotransformers for Drug‐Resistant Pan‐Cancer Therapy in Patient‐Derived Organoids

open access: yesAdvanced Science, EarlyView.
Pan‐cancer therapies are severely limited in drug‐resistance patients due to genetic mutations and other factors, resulting in poor therapeutic outcomes and constrained clinical benefit. Liquid metal nanotransformers, a new class of shape‐transformable nanomaterials capable of dramatic morphological changes, offer a promising physical strategy to ...

: influence of ancestral DNA ligase on cofactor utilization

open access: yes, 2008
DNA ligases are divided into two groups according to their cofactor requirement to form ligase-adenylate, ATP-dependent DNA ligases and NAD(+)-dependent DNA ligases.

Cuproptosis and Mitophagy Mediated by the THUMPD1/IGF2R‐Dependent Suppression of AKT and Activation of AMPK Signaling Suppress Lung Adenocarcinoma Progression

open access: yesAdvanced Science, EarlyView.
THUMPD1 drives a tumor‐suppressive signaling cascade in lung adenocarcinoma by promoting IGF2R expression. IGF2R associates with PPP2R1A to suppress AKT and activate AMPK, leading to SLC31A1 upregulation and copper accumulation. Elevated copper disrupts mitochondrial metabolism and induces excessive mitophagy, thereby restraining tumor growth and ...

Ku Recruits the XRCC4-Ligase IV Complex to DNA Ends

open access: yes, 2000
Genetic experiments have determined that Ku, XRCC4, and ligase IV are required for repair of double-strand breaks by the end-joining pathway. The last two factors form a tight complex in cells.

UCHL3 Regulates Subgenomic Flaviviral RNA Condensates to Promote Virus Propagation

open access: yesAdvanced Science, EarlyView.
ABSTRACT Flavivirus subgenomic RNAs (sfRNAs) antagonise antiviral defences, yet how sfRNAs are organized and maintained in cells remains poorly understood. Here we identify ubiquitin C‐terminal hydrolase L3 (UCHL3) as a post‐translational regulator of flavivirus sfRNA stability and function.

Epithelial TRIM27 Inhibits Intestinal Inflammation in Ulcerative Colitis by the USP7/TRIM27‐IKK Double Negative‐Feedback

open access: yesAdvanced Science, EarlyView.
ABSTRACT The E3 ubiquitin ligase tripartite motif 27 (TRIM27) is a negative regulator of NF‐κB activation and the innate immune response, and TRIM27 deficiency significantly impairs dextran sulfate sodium (DSS)‐induced colitis. The function of TRIM27 in intestinal epithelial cells (IECs), the mechanism by which TRIM27 inhibits the NF‐κB pathway and its
