Transcription‐Replication Conflicts: Unlocking New Frontiers in Cancer
BioEssays, EarlyView.Transcription‐replication conflicts (TRCs) constitute a major source of genome instability. Such conflicts are regulated by chromatin, its dysfunction causing replication stress, DNA breaks, and mutations frequently found in cancer. We review the molecular basis of TRCs and chromatin regulation and discuss the clinical potential of targeting TRCs as ...

Genetics and Molecular Biology, 2007 Chromosome analyses were performed in two grasshopper species of the genus Schistocerca, S. pallens and S. flavofasciata. Both species shared the same diploid number (2n = 23, X in males; 2n = 24, XX in females);and a conserved karyotype composed ...

Therapeutic targeting of chromatin alterations in leukemia and solid tumors
International Journal of Cancer, EarlyView.Abstract Alterations in chromatin conformation and post‐translational modification of histones have become increasingly recognized as critical drivers of cancer development, progression, and therapy resistance. Recent advances in drug development have led to the establishment of several highly selective small molecule inhibitors, several of which are ...

Identification of methotrexate as a heterochromatin-promoting drug. [PDF]
, 2019 Heterochromatin is a tightly packed form of DNA involved in gene silencing, chromosome segregation, and protection of genome stability. Heterochromatin is becoming more recognized in tumor suppression and may thus serve as a potential target for cancer ...

Local enrichment of HP1alpha at telomeres alters their structure and regulation of telomere protection. [PDF]
, 2018 Enhanced telomere maintenance is evident in malignant cancers. While telomeres are thought to be inherently heterochromatic, detailed mechanisms of how epigenetic modifications impact telomere protection and structures are largely unknown in human ...

The Antiviral Activity of Polyphenols
Molecular Nutrition &Food Research, EarlyView.Polyphenols demonstrate remarkable antiviral properties by effectively disrupting multiple biochemical processes essential for viral replication. ABSTRACT Polyphenols are secondary metabolites produced by a large variety of plants. These compounds that comprise the class of phenolic acids, stilbenes, lignans, coumarins, flavonoids, and tannins have a ...

Positional changes of pericentromeric heterochromatin and nucleoli in postmitotic Purkinje cells during murine cerebellum development [PDF]
, 2004 Previous studies revealed changes of pericentromeric heterochromatin arrangements in postmitotic Purkinje cells (PCs) during postnatal development in the mouse cerebellum (Manuelidis, 1985; Martou and De Boni, 2000). Here, we performed vibratome sections

Key Regulators of Parasite Biology Viewed Through a Post‐Translational Modification Repertoire
PROTEOMICS, EarlyView.ABSTRACT Parasites are the leading causes of morbidity and mortality in both humans and animals, imposing substantial socioeconomic burdens worldwide. Controlling parasitic diseases has become one of the key issues in achieving “One Health”. Most parasites have sophisticated life cycles exhibiting progressive developmental stages, morphologies, and ...
