Genome‐Wide Association Analyses Reveal the Genetic Basis of EMS Mutagenesis Efficiency in Rice

open access: yesAdvanced Science, EarlyView.
Based on large‐scale screening of 420 rice accessions, GWAS identified the Rc locus as a key regulator of EMS mutagenesis efficiency. Functional Rc alleles enhance both seed survival and genome‐wide mutation frequency by boosting antioxidant enzyme activities (CAT, SOD, POD) and reducing oxidative damage.

Centromere deletion in Cryptococcus deuterogattii leads to neocentromere formation and chromosome fusions

open access: yeseLife, 2020
The human fungal pathogen Cryptococcus deuterogattii is RNAi-deficient and lacks active transposons in its genome. C. deuterogattii has regional centromeres that contain only transposon relics.

Disrupting Lipid Raft Microdomains to Block Polyploid Giant Cancer Cell Budding and Enhance Radiotherapy Response

open access: yesAdvanced Science, EarlyView.
Radiation induces polyploid giant cancer cells (PGCCs) that regenerate tumors through virus‐like budding. This process depends on a SNCG–FLOT2–CHMP4B signaling axis functioning in lipid raft microdomains. Disrupting these domains using statins or anti‐PCSK9 antibodies blocks PGCC budding, suppresses tumor repopulation, and enhances radiotherapy ...

A time out for CENP-A

open access: yesMolecular & Cellular Oncology, 2017
Proper chromosome segregation relies on a functional centromere–kinetochore interface. We showed that chromatin containing CENtromere Protein A (CENP-A) is essential for centromere assembly, but dispensable for chromosome segregation in the presence of ...

CENP-A Ubiquitylation Is Inherited through Dimerization between Cell Divisions

open access: yesCell Reports, 2016
The presence of chromatin containing the histone H3 variant CENP-A dictates the location of the centromere in a DNA sequence-independent manner. But the mechanism by which centromere inheritance occurs is largely unknown. We previously reported that CENP-

Mepylome: A Point‐of‐Care Tumor Diagnostic Toolkit for Tumor DNA Methylation and Copy Number Analysis

open access: yesAdvanced Intelligent Systems, EarlyView.
DNA methylation and chromosomal copy number profiling have recently become essential for tumor diagnostics. The open‐source tool Mepylome enables this task in clinical routine. It combines several machine learning strategies and allows users to interactively examine respective data through an intuitive graphical interface. Running up to 65 times faster

The budding yeast Centromere DNA Element II wraps a stable Cse4 hemisome in either orientation in vivo

open access: yeseLife, 2014
In budding yeast, a single cenH3 (Cse4) nucleosome occupies the ∼120-bp functional centromere, however conflicting structural models for the particle have been proposed. To resolve this controversy, we have applied H4S47C-anchored cleavage mapping, which

Autoantibody Response Toward Chromatin in Patients With Juvenile Idiopathic Arthritis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Patients with juvenile idiopathic arthritis (JIA) frequently exhibit antinuclear antibodies (ANAs), but the specific antigen target recognized by them and the presence of additional autoantibody specificities in patients with JIA remains elusive.

A Randomized, Placebo‐Controlled Trial of Hydroxychloroquine in Incomplete Lupus

open access: yesArthritis &Rheumatology, EarlyView.
Objective Patients with features of systemic lupus erythematosus (SLE) who do not fulfill classification criteria can be designated as incomplete lupus erythematosus (ILE). This condition includes individuals with a high risk of progression to SLE. Treatment of ILE may reduce symptoms, severity, and incidence of SLE.

Distinct effects of complement C4A and C4B copy number in Systemic Sclerosis serological and clinical subtypes

open access: yesArthritis &Rheumatology, Accepted Article.
Objective Complement component 4 (C4), encoded by C4A and C4B within the major histocompatibility complex (MHC) on chromosome 6, regulates the immune response and clears immune complexes. Variable copy number (CN) of C4 genes and retroviral HERV‐K element influence its function.
