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.

Mesoscale phase separation of chromatin in the nucleus [PDF]

, 2020
Intact-organism imaging of Drosophila larvae reveals and quantifies chromatin-aqueous phase separation. The chromatin can be organized near the lamina layer of the nuclear envelope, conventionally fill the nucleus, be organized centrally, or as a wetting droplet.

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

Targeted Therapies in Myelofibrosis: Present Landscape, Ongoing Studies, and Future Perspectives

American Journal of Hematology, EarlyView.
ABSTRACT Myelofibrosis (MF) is a myeloproliferative neoplasm that is accompanied by driver JAK2, CALR, or MPL mutations in more than 90% of cases, leading to constitutive activation of the JAK–STAT pathway. MF is a multifaceted disease characterized by trilineage myeloid proliferation with prominent megakaryocyte atypia and bone marrow fibrosis, as ...

Aging differentially alters the transcriptome and landscape of chromatin accessibility in the male and female mouse hippocampus

Frontiers in Molecular Neuroscience
Aging-related memory impairment and pathological memory disorders such as Alzheimer’s disease differ between males and females, and yet little is known about how aging-related changes in the transcriptome and chromatin environment differ between sexes in

How short-ranged electrostatics controls the chromatin structure on much larger scales [PDF]

, 2001
We propose that the degree of sweeling of the 30nm chromatin fiber (a "measure" of its transcriptional activity) is mainly determined by the short-ranged electrostatical interaction between different sections of the "folded" DNA chain. These sections constitute only a small fraction of the chain and they are located close to the entry-exit points of ...

Clonal Hematopoiesis and Thrombosis

American Journal of Hematology, EarlyView.
ABSTRACT Clonal hematopoiesis (CH) has been the focus of many research efforts in the last years and has emerged as a risk modifier for cardiovascular disease morbidity and mortality. While substantial evidence has accumulated regarding its impact on arterial system diseases, the connection with venous thrombosis has only recently been explored.

The cardiac wound healing response to myocardial infarction

WIREs Mechanisms of Disease, Volume 15, Issue 1, January/February 2023., 2023
Cardiac wound healing after myocardial infarction is a balance between the breakdown of existing and the construction of new extracellular matrix, with inflammation feeding into both sides. Abstract Myocardial infarction (MI) is defined as evidence of myocardial necrosis consistent with prolonged ischemia.

Dynamic regulation of the transcriptome and proteome of the equine embryo during maternal recognition of pregnancy

FASEB BioAdvances, Volume 4, Issue 12, Page 775-797, December 2022., 2022
Abstract During initial maternal recognition of pregnancy (MRP), the equine embryo displays a series of unique events characterized by rapid blastocyst expansion, secretion of a diverse array of molecules, and transuterine migration to interact with the uterine surface.

Gut Microbiome Pilot Study of Patients With CHARGE Syndrome and Sibling Controls

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Difficulties with feeding and digestion are common in individuals with CHARGE syndrome. Animal models with CHD7 gene variants demonstrate abnormal gut innovation and dysmotility. Our pilot study evaluated whether individuals with CHARGE syndrome have differences in their gut microbiome compared to unaffected siblings.
