Two near‐complete assemblies reveal R‐subgenome structural and centromeric divergence associated with reproductive isolation in hexaploid triticale

open access: yesiMeta, EarlyView.
We present two near‐complete triticale genome assemblies and perform pan‐centromere analyses across >200 haplotypes from parental species, synthetic allopolyploids, cultivars, and 337 resequenced accessions, revealing a shared chromatin framework underlying functional centromeres in all three subgenomes, where wheat‐ and rye‐derived CENH3 co‐occupy ...

Anaphase Chromosomes in Crane-Fly Spermatocytes Treated With Taxol (Paclitaxel) Accelerate When Their Kinetochore Microtubules Are Cut: Evidence for Spindle Matrix Involvement With Spindle Forces

open access: yesFrontiers in Cell and Developmental Biology, 2018
Various experiments have indicated that anaphase chromosomes continue to move after their kinetochore microtubules are severed. The chromosomes move poleward at an accelerated rate after the microtubules are cut but they slow down 1–3 min later and move ...

Characterization of Pulmonary Functional Abnormalities in Systemic Sclerosis Using Xenon MRI

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Xenon MRI is increasingly used to evaluate patients with interstitial lung disease (ILD) and pulmonary hypertension (PH), both of which are common manifestations of systemic sclerosis (SSc). As such, Xe‐MRI may be suited to interrogate lung function impairment in SSc.

The Ndc80 complex bridges two Dam1 complex rings

open access: yeseLife, 2017
Strong kinetochore-microtubule attachments are essential for faithful segregation of sister chromatids during mitosis. The Dam1 and Ndc80 complexes are the main microtubule binding components of the Saccharomyces cerevisiae kinetochore.

Routine MDM2 FISH Testing and Preoperative Biopsy Reduces Recurrence Rate of Atypical Lipomatous Tumours

open access: yesJournal of Surgical Oncology, EarlyView.
ABSTRACT Background Although MDM2 FISH test has been increasingly used to differentiate ALT and benign lipomatous tumours, its impact on clinical outcome remains underexplored. This study investigated whether routine MDM2 FISH testing on preoperative biopsy is associated with a reduction in the recurrence risk of ALT.

Polar Ejection Forces Promote the Conversion from Lateral to End-on Kinetochore-Microtubule Attachments on Mono-oriented Chromosomes

open access: yesCell Reports, 2015
Chromosome bi-orientation occurs after conversion of initial lateral attachments between kinetochores and spindle microtubules into stable end-on attachments near the cell equator. After bi-orientation, chromosomes experience tension from spindle forces,

A Refractory Leg Skin Ulcer Associated With Multiple Myeloma Successfully Treated With Plasma Exchange, Lenalidomide, and Dexamethasone

open access: yesJEADV Clinical Practice, EarlyView.
ABSTRACT Multiple myeloma (MM) is a malignant plasma cell disorder that primarily presents with CRAB symptoms (calcium elevation, renal failure, anemia, and bone abnormalities). In rare cases, MM manifests with systemic complications like skin ulcers, which present management challenges. Here, we report a 78‐year‐old Japanese man with MM and refractory

Nephrogenic Systemic Fibrosis: A Rare Contemporary Case After a Decade of Declining Incidence

open access: yesJEADV Clinical Practice, EarlyView.
ABSTRACT Nephrogenic systemic fibrosis (NSF) is a rare fibrosing disorder associated with exposure to gadolinium‐based contrast agents in patients with renal impairment. Although its incidence has markedly declined since the restriction of high‐risk linear gadolinium agents, sporadic cases may still occur.

Fin1-PP1 Helps Clear Spindle Assembly Checkpoint Protein Bub1 from Kinetochores in Anaphase

open access: yesCell Reports, 2016
Summary: The spindle assembly checkpoint (SAC) monitors chromosome attachment defects, and the assembly of SAC proteins at kinetochores is essential for its activation, but the SAC disassembly process remains unknown.

The Saccharomyces cerevisiae kinetochore

open access: yesFEBS Letters, 1996
Accurate chromosome segregation is DApenDAnt on a specialized chromosomal structure, the kinetochore/centromere. The only essential constituent of the S. cerevisiae kinetochore established today is CBF3, a multisubunit complex that binds to S. cerevisiae centromere DNA.
