Central role for the XRCC1 BRCT I domain in mammalian DNA single-strand break repair [PDF]

open access: yes, 2002
The DNA single-strand break repair (SSBR) protein XRCC1 is required for genetic stability and for embryonic viability. XRCC1 possesses two BRCA1 carboxyl-terminal (BRCT) protein interaction domains, denoted BRCT I and II.

Quantitative Profiling of Nanoscopic Protein Aggregates Reveals Specific Fingerprint of TDP‐43‐Positive Assemblies in Motor Neuron Disease

open access: yesAdvanced Science, EarlyView.
Single‐molecule fluorescence microscopy is combined with proteomic profiling to fingerprint the morphology and composition of TDP‐43 protein aggregates found in post‐mortem motor neuron disease brain tissues. Aggregate fingerprints can distinguish disease from control donors and detect unexpected TDP‐43 pathology in SOD1‐MND.

An improved synthesis of adefovir and related analogues

open access: yesBeilstein Journal of Organic Chemistry, 2019
An improved synthesis of the antiviral drug adefovir is presented. Problems associated with current routes to adefovir include capricious yields and a reliance on problematic reagents and solvents, such as magnesium tert-butoxide and DMF, to achieve high

Gene Editing of a Susceptibility LncRNA Enhances Broad‐Spectrum Disease Resistance in Rice without Developmental Trade‐Offs

open access: yesAdvanced Science, EarlyView.
Editing susceptibility lncRNAs offers a strategy to enhance disease resistance without yield loss. RESIS, a domestication‐acquired, pathogen‐induced lncRNA, promotes protein N‐terminal acetylation through its interaction with NatA complex. Knockout of RESIS increases translation and confers broad‐spectrum resistance to both fungal and bacterial ...

MicroRNA‐Enriched Plant‐Derived Exosomes Alleviate Colitis by Modulating Systemic Immunity, Metabolic Homeostasis, and Gut Microbiota

open access: yesAdvanced Science, EarlyView.
Herbal medicine, with its multicomponent and multitarget potential, is often studied primarily for traditional forms, especially phytochemicals. Currently, ulcerative colitis lacks natural, low‐toxicity therapies, yet emerging research highlights plant‐derived exosomes as a promising option.

Tailoring Vascular‐Immune Homeostasis via Manganese‐DNA Complex‐Armed Immunogenic Extracellular Vesicles for Pancreatic Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
This study demonstrates that Mn2⁺–tumor DNA complexes encapsulated in dendritic cell (DC)– derived immunogenic extracellular vesicles (EVDC@Mn‐DNA) act as a DC‐specific cGAS– STING activator. EVDC@Mn‐DNA treatment enhances intratumoral DC activation, improves tumor vascular function, promotes CD8⁺ T cell activity, and suppresses pancreatic tumor growth,
