Silk Fibroin Nanoparticles for Enhanced Cuproptosis and Immunotherapy in Pancreatic Cancer Treatment

open access: yesAdvanced Science, EarlyView.
Cuproptosis can be triggered via intracellular copper overload mediated by elesclomol (ES).Enhancing ES‐Cu's tumor targeting and circulation stability can efficiently induce tumor cuproptosis. TSF@ES‐Cu protect ES‐Cu, target tumors via natural RGD sequences, and release through multi‐responsiveness.

Human kinetochores are swivel joints that mediate microtubule attachments

open access: yeseLife, 2016
Chromosome segregation is a mechanical process that requires assembly of the mitotic spindle – a dynamic microtubule-based force-generating machine.

Hydrodynamic mechanism for stable spindle positioning in meiosis II oocytes [PDF]

open access: yesPRX Life 2, 043003 (2024)
Cytoplasmic streaming, the persistent flow of fluid inside a cell, induces intracellular transport, which plays a key role in fundamental biological processes. In meiosis II mouse oocytes (developing egg cells) awaiting fertilisation, the spindle, which is the protein structure responsible for dividing genetic material in a cell, must maintain its ...

Stabilization of turning processes using spindle feedback with state-dependent delay [PDF]

open access: yes, 2017
We develop a stabilization strategy of turning processes by means of delayed spindle control. We show that turning processes which contain intrinsic state-dependent delays can be stabilized by a spindle control with state-dependent delay, and develop analytical description of the stability region in the parameter space.

PABPN1 Couples the Polyadenylation and Translation of Maternal Transcripts to Mouse Oocyte Meiotic Maturation

open access: yesAdvanced Science, EarlyView.
This study reveals that cytoplasmic PABPN1 is essential for mouse oocyte meiotic maturation by coordinating polyadenylation, translation, and degradation of maternal mRNAs. Pabpn1 knockout disrupts CDK1 activation, spindle formation, and chromosome alignment by impairing maturation‐promoting factor (MPF) regulation and BTG4‐mediated deadenylation ...

The Spindle Assembly Checkpoint Is Required for Hematopoietic Progenitor Cell Engraftment

open access: yesStem Cell Reports, 2017
Summary: The spindle assembly checkpoint plays a pivotal role in preventing aneuploidy and transformation. Many studies demonstrate impairment of this checkpoint in cancer cells.

Unveiling the complexity of cellular senescence in cancers: From mechanism to therapeutic opportunities

open access: yesBMEMat, EarlyView.
This review highlights the complex roles of cellular senescence in cancer progression and suppression, discusses the mechanisms and regulatory pathways involved, and evaluates the efficacy of the “One‐Two punch” sequential treatment approach while addressing emerging challenges in this novel therapeutic strategy.

Improving Performance of Iterative Methods by Lossy Checkponting [PDF]

open access: yes, 2018
Iterative methods are commonly used approaches to solve large, sparse linear systems, which are fundamental operations for many modern scientific simulations. When the large-scale iterative methods are running with a large number of ranks in parallel, they have to checkpoint the dynamic variables periodically in case of unavoidable fail-stop errors ...

HN1 expression contributes to mitotic fidelity through Aurora A‐PLK1‐Eg5 axis

open access: yesCytoskeleton, EarlyView.
Abstract Hematological and neurological expressed 1 (HN1) is homolog of Jupiter protein from Drosophila melanogaster where it functions as a microtubule‐associated protein. However, in mammalian cells, HN1 is associated partially with y‐tubulin in centrosomes, Stathmin for stabilizing microtubules, and Cdh1 for regulating Cyclin B1 for cell cycle ...

Phosphorylation at the Helm: Kinase‐Mediated Regulation of Primary Cilia Assembly and Disassembly

open access: yesCytoskeleton, EarlyView.
ABSTRACT The primary cilium serves as an antenna of most vertebrate cells and is important for conveying cues from several signaling pathways into appropriate cellular responses during development and homeostasis. Cilia assembly and disassembly processes are thought to be strictly controlled; however, the precise nature of molecular events underlying ...
