Unphosphorylated STAT3 in heterochromatin formation and tumor suppression in lung cancer

open access: yesBMC Cancer, 2020
Background Aberrant JAK/STAT activation has been detected in many types of human cancers. The role of JAK/STAT activation in cancer has been mostly attributed to direct transcriptional regulation of target genes by phosphorylated STAT (pSTAT), while the ...

Controlling Topology of a Telomeric G‐quadruplex DNA With a Chemical Cross‐link

open access: yesChemistry – A European Journal, EarlyView.
Thermodynamically stable G‐quadruplex (G4) DNA: Chemical cross‐linking between distant nucleotides led to formation of G4‐DNA that is stable in the presence of complementary DNA. This methodology can be used to reliably form G4s within DNA fibers for subsequent structural studies of G4‐protein interactions.

Nuclear tau and its potential role in Alzheimer’s disease [PDF]

open access: yes, 2016
Tau protein, found in both neuronal and non-neuronal cells, forms aggregates in neurons that constitutes one of the hallmarks of Alzheimer’s disease (AD).

H3K9me3-binding proteins are dispensable for SETDB1/H3K9me3-dependent retroviral silencing

open access: yesEpigenetics & Chromatin, 2011
Background Endogenous retroviruses (ERVs) are parasitic sequences whose derepression is associated with cancer and genomic instability. Many ERV families are silenced in mouse embryonic stem cells (mESCs) via SETDB1-deposited trimethylated lysine 9 of ...

Dynamic expression of lamin B1 during adult neurogenesis in the vertebrate brain

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background In mammals, specific brain regions such as the dentate gyrus (DG) of the hippocampus and the subventricular zone (SVZ) of the lateral ventricles harbor adult neural stem/progenitor cells (ANSPCs) that give rise to new neurons and contribute to structural and functional brain plasticity.

Biphasic euchromatin-to-heterochromatin transition on the KSHV genome following de novo infection. [PDF]

open access: yes, 2013
The establishment of latency is an essential step for the life-long persistent infection and pathogenesis of Kaposi's sarcoma-associated herpesvirus (KSHV).

Epigenotoxicity: Decoding the epigenetic imprints of genotoxic agents and their implications for regulatory genetic toxicology

open access: yesEnvironmental and Molecular Mutagenesis, EarlyView.
Abstract Regulatory genetic toxicology focuses on DNA damage and subsequent gene mutations. However, genotoxic agents can also affect epigenetic marks, and incorporation of epigenetic data into the regulatory framework may thus enhance the accuracy of risk assessment.

Research progress on the role of inflammatory mediators in the pathogenesis of epilepsy

open access: yesIbrain, Volume 11, Issue 1, Page 44-58, Spring 2025.
In the central nervous system, activated immune cells lead to the overproduction of inflammatory mediators through the corresponding signal pathway. Under the stimulation of inflammatory factors, neuroinflammation ultimately occurs. Overexpression of inflammatory mediators and activated immunocytes plays an important role in the emergence and ...

Epigenetic Chromatin Silencing: Bistability and Front Propagation

open access: yes, 2007
The role of post-translational modification of histones in eukaryotic gene regulation is well recognized. Epigenetic silencing of genes via heritable chromatin modifications plays a major role in cell fate specification in higher organisms.

Maintenance of Nucleolar Homeostasis by CBX4 Alleviates Senescence and Osteoarthritis

open access: yesCell Reports, 2019
Summary: CBX4, a component of polycomb repressive complex 1 (PRC1), plays important roles in the maintenance of cell identity and organ development through gene silencing. However, whether CBX4 regulates human stem cell homeostasis remains unclear. Here,
