Attachment and tension in the spindle assembly checkpoint [PDF]

Journal of Cell Science, 2002
Faithful transmission of chromosomes during mitosis is ensured by the spindle assembly checkpoint. This molecular safeguard examines whether prerequisites for chromosome segregation have been satisfied and thereby determines whether to execute or to delay chromosome segregation.

Nanomedicine Meets Immunotherapy: Advancing Adoptive Cell Therapy with Nanoparticles in the Treatment of Cancer with Sustainability Perspectives

Advanced Science, EarlyView.
This review surveys nanoparticle‐based strategies to enhance adoptive cell therapy, particularly CAR‐T cell approaches, in solid tumor treatment. It describes how nanoparticles can improve tumor immunogenicity and T‐cell infiltration while reducing toxicity, and how they enable in vivo CAR‐T cell generation.

Xenopus oocyte meiosis lacks spindle assembly checkpoint control [PDF]

Journal of Cell Biology, 2013
The spindle assembly checkpoint (SAC) functions as a surveillance mechanism to detect chromosome misalignment and to delay anaphase until the errors are corrected. The SAC is thought to control mitosis and meiosis, including meiosis in mammalian eggs.

Silencing the spindle assembly checkpoint: Let’s play Polo! [PDF]

Journal of Cell Biology, 2020
Silencing of the spindle assembly checkpoint involves two protein phosphatases, PP1 and PP2A-B56, that are thought to extinguish checkpoint signaling through dephosphorylation of a checkpoint scaffold at kinetochores. In this issue, Cordeiro et al. (2020. J.

Cell Cycle‐Specific Regulation of Centrosome Clustering Dynamics in Cancer Cells by the Multifunctional Kinesin HSET

Advanced Science, EarlyView.
CDK5RAP2 associates with the kinesin HSET and forms co‐condensates. HSET motors drive the directional transport of CDK5RAP2 condensates toward microtubule minus ends. During mitosis, HSET self‐assembly further stabilizes clustered centrosomes, thereby enabling pseudo‐bipolar spindle formation in cancer cells with supernumerary centrosomes. Upon mitotic

Engineering Tertiary Lymphoid Structures: Nanomedicine, Bioengineering, and Biomaterials for Precision Immunotherapy

Advanced NanoBiomed Research, EarlyView.
This review explains how biomaterials and nanoparticles can be used to induce or modulate tertiary lymphoid structures (TLSs), which are ectopic immune hubs that form in nonlymphoid tissues during chronic disease and cancer. By comparing different methods, the article highlights design principles for modeling TLSs or recapitulating specific TLS ...

Bub1 positions Mad1 close to KNL1 MELT repeats to promote checkpoint signalling

Nature Communications, 2017
The spindle assembly checkpoint ensures correct chromosome segregation and relies on kinetochore localization of the Bub1 and Mad1/Mad2 checkpoint proteins.

Making Two out of One: Kinesin Motors Driving Plant Cell Division

Cytoskeleton, EarlyView.
ABSTRACT The Kinesin superfamily of microtubule dependent motors is present in all eukaryotes. Not all of the subfamilies are represented in all kingdoms, and the ones that are do not always show conserved functions. Tight control of the cytoskeleton is essential for proper progression and completion of mitosis and cytokinesis, and key functions are ...

bir1 deletion causes malfunction of the spindle assembly checkpoint and apoptosis in yeast

Frontiers in Oncology, 2012
Cell division in yeast is a highly regulated and well studied event. Various checkpoints are placed throughout the cell cycle to ensure faithful segregation of sister chromatids.

Tracing the Pathway of Spindle Assembly Checkpoint Signaling [PDF]

Developmental Cell, 2001
Most current models of spindle assembly checkpoint signaling involve inhibition of the Cdc20-APC by Mad2 protein. Interestingly, a paper from Hongtao Yu and colleagues in this issue of Developmental Cell suggests that the Cdc20/APC can also be inhibited in a Mad2-independent manner by a complex of proteins that includes BubR1.
