Kinetochore dynein is sufficient to biorient chromosomes and remodel the outer kinetochore
Multiple microtubule-directed activities concentrate on mitotic chromosomes to ensure their faithful segregation. These include couplers and dynamics regulators localized at the kinetochore, the microtubule interface built on centromeric chromatin, as ...

CENP-meta, an essential kinetochore kinesin required for the maintenance of metaphase chromosome alignment in Drosophila. [PDF]
CENP-meta has been identified as an essential, kinesin-like motor protein in Drosophila. The 257-kD CENP-meta protein is most similar to the vertebrate kinetochore-associated kinesin-like protein CENP-E, and like CENP-E, is shown to be a component of ...

Chromosome segregation in plant meiosis [PDF]
Faithful chromosome segregation in meiosis is essential for ploidy stability over sexual life cycles. In plants, defective chromosome segregation caused by gene mutations or other factors leads to the formation of unbalanced or unreduced gametes creating

ABSTRACT Chromosomal aberrations, particularly copy‐number variations (CNVs), are prevalent in neurodevelopmental disorders (NDD) and significantly contribute to their pathogenesis. Copy‐number gains (CN gains) in 15q11‐q13, primarily consisting of a pseudo (iso‐)dicentric chromosome 15 [(i)dic(15)] or an interstitial duplication, are among the most ...

ABSTRACT Turner Syndrome (TS) is a sex chromosomal disorder associated with karyotype heterogeneity. Although TS can be associated with severe prenatal findings, most often linked to the 45, X karyotype, the majority of TS fetuses have no overt phenotype, resulting in delayed diagnosis and management.

Directional instability of microtubule transport in the presence of kinesin and dynein, two opposite polarity motor proteins. [PDF]
Kinesin and dynein are motor proteins that move in opposite directions along microtubules. In this study, we examine the consequences of having kinesin and dynein (ciliary outer arm or cytoplasmic) bound to glass surfaces interacting with the same ...

The aim of this study was to improve the long‐term LL‐37 mouse model and compare the disease manifestations and pathophysiology of short‐term and long‐term LL‐37‐induced rosacea‐like models. The results show that the long‐term LL‐37 induced mouse model provides a practical animal model for further study of the pathological mechanism of severe rosacea ...

Objective Raynaud phenomenon (RP) is often the initial clinical manifestation of systemic sclerosis (SSc), but some patients develop other manifestations first. To help elucidate the diversity of SSc presentation in its early stages, we describe the initial clinical manifestations and antinuclear antibody (ANA) profiles of patients in two early SSc ...

Loss of APC induces polyploidy as a result of a combination of defects in mitosis and apoptosis [PDF]
Mutations in the adenomatous polyposis coli (APC) tumor suppressor gene initiate a majority of colorectal cancers. Acquisition of chromosomal instability is an early event in these tumors.

Autoantibody response towards chromatin in patients with juvenile idiopathic arthritis
Objective Juvenile idiopathic arthritis (JIA) patients frequently exhibit antinuclear antibodies (ANAs), but the specific antigen target recognized by them and the presence of additional autoantibody specificities in JIA patients remains elusive. Methods Plasma samples from 110 untreated patients with active JIA, as well as from 14 children with ...
