Microfluidic Nano‐Assembly of Red‐Blood‐Cell (RBC) Lipids and Components for Engineering Extracellular Vesicles

Advanced Healthcare Materials, EarlyView.
Engineered red blood cell‐derived extracellular vesicles (eRBCEVs) are synthesized via controlled microfluidic assembly from native RBC lipids, enabling tunable encapsulation of proteins, nucleic acids, nanoparticles, and viral vectors. The platform demonstrates reproducible nanoscale architecture, preserved membrane composition, and functional cargo ...

Patient‐Derived 3D Heart‐On‐a‐Chip Model of Dilated Cardiomyopathy With Embedded Bead‐Based Mapping of Tissue Contractility

Advanced Healthcare Materials, EarlyView.
A heart‐on‐a‐chip model of dilated cardiomyopathy is developed from patient‐derived induced pluripotent stem cells. The model recapitulates key disease phenotypes and enables functional assessment through integrated bead‐based tracking and pillar deflection measurements.

DNA Damage Response in Nucleoli

Molecular Biology, 2021
Nucleoli, the largest subnuclear compartments, are formed around arrays of ribosomal gene repeats transcribed by RNA polymerase I. The primary function of nucleoli is ribosome biogenesis. Specific DNA damage response mechanisms exist to maintain the genomic stability of ribosomal repeats.

DNA damage response and transcription

DNA Repair, 2011
A network of DNA damage surveillance systems is triggered by sensing of DNA lesions and the initiation of a signal transduction cascade that activates genome-protection pathways including nucleotide excision repair (NER). NER operates through coordinated assembly of repair factors into pre- and post-incision complexes.

The cellular responses to DNA damage

Trends in Cell Biology, 1995
The ability to survive spontaneous and induced DNA damage, and to minimize the number of heritable mutations that this causes, is essential to the maintenance of genome integrity for all organisms. Early studies on model eukaryotes focused on genes acting in defined DNA repair pathways. More recent work with the budding and fission yeasts and mammalian

Cellular Response to DNA Damage

Annals of the New York Academy of Sciences, 2006
Abstract: Eukaryotic cells, from yeast to man, possess evolutionarily conserved mechanisms to accurately and efficiently repair the overwhelming majority of DNA damage, thereby ensuring genomic integrity. Important repair pathways include base excision repair, nucleotide excision repair, mismatch repair, non‐homologous end‐joining, and homologous ...

DNA damage response and neuroprotection

Frontiers in Bioscience, 2008
The protection of genomic integrity is a major challenge for living cells that are continuously exposed to endogenous and environmental DNA-damaging insults. To cope with the consequences of DNA lesions which interfere with essential DNA-dependent processes including transcription and replication, cells are equipped with an efficient defense mechanism ...

Regulators in the DNA damage response

Archives of Biochemistry and Biophysics, 2016
Maintenance of genome integrity is essential for the proper function of all cells and organisms. In response to both endogenous and exogenous DNA damaging agents, mammalian cells have evolved a delicate system to sense DNA damage, stop cell cycle progression, modulate cell metabolism, repair damaged DNA, and induce programmed cell death if the damage ...

Chromatin and the DNA damage response

DNA Repair, 2005
The impact of chromatin structure upon the DNA damage response is becoming increasingly apparent. We can reasonably expect many more papers showing how chromatin and chromatin modifications impact upon aspects of the DNA damage response. Here, we present our perspective on some recent developments in this exciting area of cell biology. We aim that this

The p53 response to DNA damage

DNA Repair, 2004
The p53 tumour suppressor protein is a highly potent transcription factor which, under normal circumstances, is maintained at low levels through the action of MDM2, an E3 ubiquitin ligase which directs p53 ubiquitylation and degradation. Expression of the mdm2 gene is stimulated by p53 and this reciprocal relationship forms the basis of a negative ...
