EccDNA‐Driven VPS41 Amplification Alleviates Genotoxic Stress via Lysosomal KAI1 Degradation

Advanced Science, EarlyView.
Following ionizing radiation, eccDNA‐mediated VPS41 amplification slightly increases its expression but fails to prevent apoptosis. Introducing exogenous eccDNA or VPS41 enhances VPS41‐KAI1 interaction, promoting lysosomal degradation of KAI1. This process inhibits apoptotic signaling, enhancing cell survival and resistance to radiation‐induced damage.

Validation of cytogenetic risk groups according to International Prognostic Scoring Systems by peripheral blood CD34+FISH: results from a German diagnostic study in comparison with an international control group

Haematologica, 2015
International Prognostic Scoring Systems are used to determine the individual risk profile of myelodysplastic syndrome patients. For the assessment of International Prognostic Scoring Systems, an adequate chromosome banding analysis of the bone marrow is

A Novel OsMPK6‐OsMADS47‐PPKL1/3 Module Controls Grain Shape and Yield in Rice

Advanced Science, EarlyView.
OsMADS47 is identified as a key regulator governing rice grain morphology. Phosphorylation‐dependent regulation of its activity directs the development of slender versus round grains, modulating both yield and appearance. This mechanism bridges cellular signaling with transcriptional regulation, establishing a molecular framework for grain optimization.

Genetic Regulation of Alternative Polyadenylation Provides Novel Insights into Molecular Mechanisms Underlying Non‐small Cell Lung Cancer

Advanced Science, EarlyView.
Compared with the non‐risk G allele of rs9606, the risk T allele of rs9606 decreases the binding affinity of NUDT21 for LYRM4, triggering 3'UTR shortening that stabilizes LYRM4 mRNA and elevates its expression. Increased LYRM4 expression promoted malignant phenotypes of non‐small cell lung cancer (NSCLC) cells through modulating ferroptosis, supporting

A Geometric Approach For Fully Automatic Chromosome Segmentation [PDF]

arXiv, 2011
A fundamental task in human chromosome analysis is chromosome segmentation. Segmentation plays an important role in chromosome karyotyping. The first step in segmentation is to remove intrusive objects such as stain debris and other noises. The next step is detection of touching and overlapping chromosomes, and the final step is separation of such ...

Meiotic behavior of two polyploid species of genus Pleurodema (Anura: Leiuperidae) from central Argentina [PDF]

, 2014
Polyploidy is an important evolutionary force but rare in vertebrates. However, in anurans, the genus Pleurodema has polyploid species, two of them tetraploid and one octoploid.

Radiation Exposure Induced Blood–Brain Barrier Injury via Mitochondria‐Mediated Sterile Inflammation

Advanced Science, EarlyView.
This work describes a blood–brain barrier (BBB) microphysiological system (MPS) to explore the responses of BBB to radiation exposure. Following radiation exposure, obvious BBB comprise and brain endothelial injuries are detected. Mechanism study shows radiation induced significant sterile inflammation via mitochondrial dysfunction and cGAS‐STING ...

Natural selection on human Y chromosomes [PDF]

Journal of Genetics and Genomics,2014,41(2):47-52, 2013
The paternally inherited Y chromosome has been widely used in population genetic studies to understand relationships among human populations. Our interpretation of Y chromosomal evidence about population history and genetics has rested on the assumption that all the Y chromosomal markers in the male-specific region (MSY) are selectively neutral ...

Delineation of individual human chromosomes in metaphase and interphase cells by in situ suppression hybridization using recombinant DNA libraries [PDF]

, 1988
A method of in situ hybridization for visualizing individual human chromosomes from pter to qter, both in metaphase spreads and interphase nuclei, is reported.
