Organelle Localization‐Induced Bio‐Orthogonal Polymerization (OLIBOP) for Photostable Super‐Resolution Live‐Cell Imaging

Advanced Healthcare Materials, EarlyView.
Organelle localization‐induced biorthogonal polymerization enables direct synthesis of photostable poly‐AIEgens within targeted organelles for super‐resolution live‐cell imaging. ABSTRACT Real‐time monitoring of dynamic biological processes demands fluorescent probes that can withstand prolonged light exposure without photobleaching—a critical ...

Acetylation, Deacetylation and Acyltransfer [PDF]

Environmental Health Perspectives, 1983
N-Substituted aromatic compounds can be metabolized in most species to N-acetylated derivatives that are themselves subject to further enzymatic transformations, including hydrolysis and N,O-acyltransfer. These proceses can either potentiate or ameliorate the biological responses to these N-substituted derivatives. Decreasing the levels of metabolites,

HDAC-mediated control of ERK- and PI3K-dependent TGF-β-induced extracellular matrix-regulating genes [PDF]

, 2010
Histone deacetylases (HDACs) regulate the acetylation of histones in the control of gene expression. Many non-histone proteins are also targeted for acetylation, including TGF-ß signalling pathway components such as Smad2, Smad3 and Smad7. Our studies in

Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction

Advanced 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 ...

Acetylation of histones and non-histone proteins is not a mere consequence of ongoing transcription

Nature Communications
In all eukaryotes, acetylation of histone lysine residues correlates with transcription activation. Whether histone acetylation is a cause or consequence of transcription is debated.

Microtubule acetylation is not required for HIV-1 infection or TRIM69-mediated restriction of HIV-1 infection

Journal of Virology
Microtubule acetylation, a post-translational modification catalyzing the addition of acetyl groups to lysine residues on alpha tubulin, confers mechanical resilience to microtubules and influences intracellular cargo transport.

Epigenetic Regulation of Matrix Metalloproteinase-1 and -3 Expression in Mycobacterium tuberculosis Infection. [PDF]

, 2017
In pulmonary tuberculosis (TB), the inflammatory immune response against Mycobacterium tuberculosis (Mtb) is associated with tissue destruction and cavitation, which drives disease transmission, chronic lung disease, and mortality.

The Epigenetic Landscape of Pancreatic Cancer Stem Cells

Epigenomes, 2018
Data now indicates that in addition to genetic alterations/mutations, human cancer cells exhibit important changes in their epigenome. In the context of this review, we define the epigenome as the chemical compounds and/or proteins that can interact with
