H3 K36 Methylation Helps Determine the Timing of Cdc45 Association with Replication Origins

open access: yes, 2009
BackgroundReplication origins fire at different times during S-phase. Such timing is determined by the chromosomal context, which includes the activity of nearby genes, telomeric position effects and chromatin structure, such as the acetylation state of ...

Histone Chaperone Jun Dimerization Protein 2 (JDP2): Role in Cellular Senescence and Aging

open access: yesKaohsiung Journal of Medical Sciences, 2010
Transcription factor Jun dimerization protein 2 (JDP2) binds directly to histones and DNA, and inhibits p300-mediated acetylation of core histones and reconstituted nucleosomes that contain JDP2-recognition DNA sequences.

T‐Cell Exhaustion in the Tumor Microenvironment: Subcellular Dysfunction, Pan‐Cancer Characteristics, and Therapeutic Interventions

open access: yesAdvanced Science, Volume 13, Issue 33, 15 June 2026.
This study elucidates the mechanisms of subcellular multidimensional collapse in exhausted T cells. By specifically targeting the nucleus, mitochondria, and endoplasmic reticulum, strategic interventions can effectively remodel the compromised organelle network. This integrated approach drives comprehensive T cell resuscitation, ultimately establishing

Nuclear Entanglement: New Insights Into the Role of Cytoskeleton and Nucleoskeleton in Plant Nuclear Function

open access: yesCytoskeleton, Volume 83, Issue 6, Page 354-375, June 2026.
ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

In Vitro Live Cell Imaging Reveals Nuclear Dynamics and Role of the Cytoskeleton During Asymmetric Division of Pollen Mitosis I in Nicotiana Benthamiana

open access: yesCytoskeleton, Volume 83, Issue 6, Page 394-406, June 2026.
ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...

Sensing and Communicating β‐Cell Stress in the Context of T1D Etiology: New Opportunities for Therapeutic Impact

open access: yesComprehensive Physiology, Volume 16, Issue 3, June 2026.
Type 1 diabetes (T1D) results from the immune‐mediated destruction of insulin‐producing pancreatic β‐cells. Recent human studies show that early β‐cell stress maladaptations precede overt immune cell infiltration. DOC2B, a vesicle secretion regulatory protein that supports β‐cell functionality and resilience against stress, declines early in T1D ...

Transcriptomic analysis identifies B-lymphocyte kinase as a therapeutic target for desmoplastic small round cell tumor cancer stem cell-like cells

open access: yesOncogenesis
Desmoplastic small round cell tumor (DSRCT) is an aggressive pediatric cancer caused by the EWSR1-WT1 fusion oncoprotein. The tumor is refractory to treatment with a 5-year survival rate of only 15–25%, necessitating the development of novel therapeutics,

Lysine lactylation‐mediated post‐translational modification: Molecular mechanisms and therapeutic target exploration in tumour drug resistance

open access: yesClinical and Translational Medicine, Volume 16, Issue 6, June 2026.
Lysine lactylation (Kla) serves as a metabolic–epigenetic switch governed by writer–eraser–reader regulatory systems, directly connecting the Warburg effect to diverse forms of tumour drug resistance. Intratumoural lactylation critically contributes to treatment failure in chemotherapy, targeted therapy and immunotherapy.

Male meiotic spindle poles are stabilized by TACC3 and cKAP5/chTOG differently from female meiotic or somatic mitotic spindles in mice

open access: yesScientific Reports
Transforming acidic acid coiled-coil protein 3 (TACC3) and cytoskeleton associated protein 5 (cKAP5; or colonic hepatic tumor overexpressed gene, chTOG) are vital for spindle assembly and stabilization initiated through TACC3 Aurora-A kinase interaction.

Temporal dynamics of cytomegalovirus chromatin assembly in productively infected human cells

open access: yes, 2008
The genomes of herpesviruses, including human cytomegalovirus (CMV), are double-stranded DNA molecules maintained as episomes during infection. The viral DNA lacks histones when encapsidated in the virion.
