Investigating transcription factor dynamics in health and disease using FRAP

FEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Studies toward in vitro reconstitution of plant chromatin [PDF]

, 2009
To study the relation between chromatin structure and DNA function in detail it is necessary to have an in vitro procedure for assembling nucleosomes on a naked DNA template with properties similar to native chromatin.

Nuclear factor I genomic binding associates with chromatin boundaries [PDF]

, 2013
BACKGROUND: The Nuclear Factor I (NFI) family of DNA binding proteins (also called CCAAT box transcription factors or CTF) is involved in both DNA replication and gene expression regulation.

Structural basis of cyclobutane pyrimidine dimer recognition by UV-DDB in the nucleosome

Nature Communications
In mammalian global genomic nucleotide excision repair, UV-DDB plays a central role in recognizing DNA lesions, such as 6-4 photoproducts and cyclobutane pyrimidine dimers, within chromatin.

Tumorigenic Cell Reprogramming and Cancer Plasticity: Interplay between Signaling, Microenvironment, and Epigenetics

Stem Cells International, 2018
Accumulating evidences indicate that many tumors rely on subpopulations of cancer stem cells (CSCs) with the ability to propagate malignant clones indefinitely and to produce an overt cancer.

Modulation of the functional interfaces between retroviral intasomes and the human nucleosome

mBio, 2023
Infection by retroviruses as HIV-1 requires the stable integration of their genome into the host cells. This process needs the formation of integrase (IN)-viral DNA complexes, called intasomes, and their interaction with the target DNA wrapped around ...

The Texture of Chromatin [PDF]

Cell, 2019
DNA-replication machinery introduces intertwining and supercoiling of DNA strands as it traverses the double helix, which could impede replication and compromise genome stability. A new study in Cell shows that the intrinsic physical properties of chromatin fibers dictate how torsional stress is partitioned to minimize these risks and facilitate DNA ...

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Chromatin state analysis of the barley epigenome reveals a higher-order structure defined by H3K27me1 and H3K27me3 abundance [PDF]

, 2015
This work was supported by grant BBSRC BB/I1022899/1 ‘The diversity and evolution of the gene component of the barley pericentromeric heterochromatin’.Combinations of histones carrying different covalent modifications are a major component of epigenetic ...

DDK/Hsk1 phosphorylates and targets fission yeast histone deacetylase Hst4 for degradation to stabilize stalled DNA replication forks

eLife, 2021
In eukaryotes, paused replication forks are prone to collapse, which leads to genomic instability, a hallmark of cancer. Dbf4-dependent kinase (DDK)/Hsk1Cdc7 is a conserved replication initiator kinase with conflicting roles in replication stress ...
