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.

S3RL: Enhancing Spatial Single‐Cell Transcriptomics With Separable Representation Learning
Advanced Science, EarlyView.Separable Spatial Representation Learning (S3RL) is introduced to enhance the reconstruction of spatial transcriptomic landscapes by disentangling spatial structure and gene expression semantics. By integrating multimodal inputs with graph‐based representation learning and hyperspherical prototype modeling, S3RL enables high‐fidelity spatial domain ...

Animal cell cytokinesis: the role of dynamic changes in the plasma membrane proteome and lipidome [PDF]
, 2016 In animal cells, cytokinesis is characterised by the formation of the mitotic spindle that signals the assembly of an actomyosin ring between the spindle poles.

Advanced Science, EarlyView.A multifunctional mPDZM nanoplatform is developed in this study. mPDZM integrates chemotherapy‐induced senescence, selective senolysis, and STING‐mediated immune activation. mPDZM effectively clears senescent tumor cells, remodels the tumor immune microenvironment, and enhances antitumor T‐cell responses.

Silencing the spindle assembly checkpoint: Let's play Polo! [PDF]
J Cell Biol, 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.

No stretch for spindle assembly checkpoint [PDF]
The Journal of Cell Biology, 2008 ![][1] Kinetochores (red) attach to the spindle (green), whereas chromatin (blue) is largely excluded. Dividing cells aren't quite as obsessed with quality control as previously thought, according to results from [O'Connell and colleagues][2].

Axin-1 Regulates Meiotic Spindle Organization in Mouse Oocytes. [PDF]
PLoS ONE, 2016 Axin-1, a negative regulator of Wnt signaling, is a versatile scaffold protein involved in centrosome separation and spindle assembly in mitosis, but its function in mammalian oogenesis remains unknown.

Latrunculin A delays anaphase onset in fission yeast by disrupting an ase1-independent pathway controlling mitotic spindle stability [PDF]
, 2008 It has been proposed previously that latrunculin A, an inhibitor of actin polymerization, delays the onset of anaphase by causing spindle misorientation in fission yeast.

Mimicking Ndc80 phosphorylation triggers spindle assembly checkpoint signalling [PDF]
The EMBO Journal, 2009 The protein kinase Mps1 is, among others, essential for the spindle assembly checkpoint (SAC). We found that Saccharomyces cerevisiae Mps1 interacts physically with the N-terminal domain of Ndc80 (Ndc80(1-257)), a constituent of the Ndc80 kinetochore complex.

Advanced Science, EarlyView.This study develops an iridium‐based nanozyme (IIN@M) with superior enzyme‐like activity and photothermal performance. It disrupts intracellular redox balance by generating reactive oxygen species and depleting glutathione, which synergistically induces ferroptosis, pyroptosis, and immunogenic cell death.
