Chromosome study in Schistocerca (Orthoptera-Acrididae-Cyrtacanthacridinae): karyotypes and distribution patterns of constitutive heterochromatin and nucleolus organizer regions (NORs). [PDF]
, 2018 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 con- served karyotype composed ...

The Antiviral Activity of Polyphenols
Molecular Nutrition &Food Research, Volume 69, Issue 15, August 2025.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 ...

hTERT Increases TRF2 to Induce Telomere Compaction and Extend Cell Replicative Lifespan
Aging Cell, Volume 24, Issue 8, August 2025.In contrast to the dogma that a subset of short telomeres initiates senescence, hTERT variants unable to maintain telomere length block senescence by stabilizing TRF2 via inhibiting upstream E3 ubiquitin ligases. This noncanonical hTERT function also compacts telomeres and blocks senescence‐associated DNA damage signaling. Cancer cells expressing hTERT

Histone marks enable formation of immiscible phase-separated chromatin compartments
Cell ReportsSummary: Eukaryotic chromatin is organized into compartments for gene expression regulation, but the underlying mechanisms remain unclear. Here, we demonstrate that multivalent H3K27me3 and its reader, the CBX7-PRC1 complex, regulate facultative ...

Genetic Architecture of Immune Cell DNA Methylation in the Rhesus Macaque
Molecular Ecology, Volume 34, Issue 15, August 2025.ABSTRACT Genetic variation that impacts gene regulation, rather than protein function, can have strong effects on trait variation both within and between species. Epigenetic mechanisms, such as DNA methylation, are often an important intermediate link between genotype and phenotype, yet genetic effects on DNA methylation remain understudied in natural ...
