Iron homeostasis disruption and lipid peroxidation in skeletal muscle during short‐term immobilization

open access: yesFEBS Open Bio, EarlyView.
14‐day casting‐induced immobilization reduced gastrocnemius muscle mass and increased non‐heme iron and ferritin heavy chain levels. Despite iron accumulation, transferrin receptor 1 and iron regulatory protein 2 were paradoxically upregulated. Lipid peroxidation was elevated without compensatory antioxidant responses.

Loss of CTLH component MAEA impairs DNA repair and replication and leads to developmental delay

open access: yesEMBO Molecular Medicine
Ubiquitin E3 ligases play crucial roles in the DNA damage response (DDR) by modulating the turnover, localization, activation, and interactions of DDR and DNA replication proteins.

New Aspects of HECT-E3 Ligases in Cell Senescence and Cell Death of Plants

open access: yesPlants, 2019
Plant cells undergo massive orderly changes in structure, biochemistry, and gene expression during cell senescence. These changes cannot be distinguished from the hydrolysis/degradation function controlled by the ubiquitination pathway, autophagy, and ...

siRNA Delivery via Cross‐Linked Gelatin Microparticles Enables Targeted Modulation of Osteogenic‐Vascular Cross‐Talk: An Advanced Human 3D in Vitro Test System for Therapeutic siRNA

open access: yesAdvanced Healthcare Materials, EarlyView.
Osteogenic‐angiogenic cross‐talk is a vital prerequisite for vascularized bone regeneration. In this study, we investigated the effects of siRNA‐mediated silencing of two inhibitory proteins, Chordin and WWP‐1, via CaP‐NP‐loaded gelatin microparticles in osteogenically differentiated microtissues.

MDC1 mediates Pellino recruitment to sites of DNA double-strand breaks

open access: yesLife Science Alliance
RING E3 ubiquitin ligases Pellino 1 and 2 are recruited to sites of DNA damage via their non-canonical FHA domains that recognise conserved phosphorylated sequence motifs in the DNA damage adaptor protein MDC1.

Tankyrases Promote Homologous Recombination and Check Point Activation in Response to DSBs.

open access: yesPLoS Genetics, 2016
DNA lesions are sensed by a network of proteins that trigger the DNA damage response (DDR), a signaling cascade that acts to delay cell cycle progression and initiate DNA repair.

Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction

open access: yesAdvanced Healthcare Materials, EarlyView.
Atherosclerosis management is hindered by poor drug targeting and plaque heterogeneity. Nanotechnology overcomes these barriers via three core strategies: (1) target‐engineered nanocarriers that achieve lesion‐specific precision via ligand modification, biomimetic camouflage, stimuli‐responsive release, and self‐propelling nanomotors; (2) catalytic ...

The STUbL RNF4 regulates protein group SUMOylation by targeting the SUMO conjugation machinery

open access: yesNature Communications, 2017
SUMO and ubiquitin are key signal transducers in several cellular processes including the DNA-damage response. Here the authors describe a method for selective enrichment of ubiquitin substrates for E3 ligases from complex cellular proteomes and identify

Decoupling Dynamics and Crosslink Stability in Supramolecular Hydrogels Using Associative Exchange

open access: yesAdvanced Materials, EarlyView.
How does reorganization impact the stability of supramolecular hydrogels? In contrast to dissociative crosslink exchange, implementing associative exchange in macroscale DNA hydrogels enables decoupling of reorganization dynamics from thermal and mechanical stability.

Comparative analysis of T4 DNA ligases and DNA polymerases used in chromosome conformation capture assays

open access: yesBioTechniques, 2015
Three-dimensional (3-D) genome organization in the nuclear space affects various genomic functions. Circular chromosome conformation capture (4C-seq) is a powerful technique that allows researchers to measure long-range chromosomal interactions with a ...
