PRC2.1 Coordinates Peri‐Nucleolar H3K27me3‐Enriched Heterochromatin Organization and NPM1 Pentamerization to Maintain Nucleolar Integrity

open access: yesAdvanced Science, EarlyView.
PRC2.1(PCL2)‐coordinated H3K27me3‐enriched PNH establishes a spatial scaffold crucial for nucleolar integrity. As a crucial coordinator, PCL2 links PRC2.1 to chromatin organization and NPM1 assembly. This network‐based model reveals how chromatin modifications and nucleolar components cooperatively maintain nucleolar architecture, revealing novel ...

Study of mitotic index in Nayband bay coral reefs [PDF]

open access: yes, 2013
Coral reefs which are one of the most significant marine ecosystems have symbiosis with zooxanthella for their growth and survival. Today zooxanthella and coral symbiosis is in the danger of anthropogenic and global climate changes.

Comparative Oligo‐FISH Mapping Illuminates Chromosomal Evolution Among Rutaceae Species Diverged Over 50 Million Years

open access: yesAdvanced Science, EarlyView.
Oligonucleotide‐based fluorescence in situ hybridization probes were developed in the model citrus species Citrus maxima. These probes were applied to comparative karyotyping across 14 species in the Rutaceae family. This analysis revealed chromosomal evolution in lineages that diverged from Citrus nearly 52 million years ago.

Gamma Ray Reduces Mitotic Index in Embryonic Roots of Hordeum vulgare L.

open access: yes, 2007
: In the present research, the effects of gamma radiation on mitotic index have been investigated. Seedsof Hordeum vulgare L. were treated with different doses of gamma ray (50, 100, 150, 200, 250, 300 Gy).

Mitotic Index of Psoriatic Lesions Treated with Anthralin, Glucocorticosteriod and Occlusion Only

open access: yes, 1970
Nine patients with psoriasis were studied with regard to the effect of local medication on the mitotic index. Cordran® tape, anthralin and Blenderm® tape were compared with an untreated control. Applications were made 23 of 24 hours for 4 days before the

Combining Fret and Super‐Resolution Microscopy Reveals Kinase Activation and Mitochondrial Activity at the Nanoscale

open access: yesAdvanced Science, EarlyView.
BioSenSRRF is an open‐source workflow that combines conventional FRET biosensors with SRRF reconstruction to generate sub‐diffraction FRET index maps on standard microscopes. The pipeline integrates automated image registration, SRRF reconstruction, quantitative FRET index calculation, and random line‐based hotspot analysis to uncover AURKA‐dependent ...

Mitotic index in Down syndrome - Is it an indicator of immunological status

open access: yes, 2004
Down syndrome (DS) is a condition in which the genes on chromosome 21 occur in three copies. This is supposed to influence the growth in the tissues of the body and this could lead to a decreased mitotic index.
