Dynamics of the Mammalian Placental Metabolome in Placentogenesis and Embryonic Development

Advanced Science, EarlyView.
This study identifies three metabolic stages (E8.5, E9.5–10.5, E11.5–14.5) and two transition periods (E8.5–9.5, E10.5–11.5) in mouse placental development. NAD(H) emerges as a key dynamic metabolite that enhances embryonic growth through accelerated segmentation and increased proliferation of mouse embryonic stem cell (mESC)‐induced presomitic ...

Precocious centriole disengagement and centrosome fragmentation induced by mitotic delay

Nature Communications, 2017
The spindle assembly checkpoint delays mitotic progression until sister chromatids are bi-oriented. Here the authors show that moderate delays in mitotic progression induce centrosome fragmentation and centriole disengagement and that spindle bipolarity ...

Decoding Human Placental Cellular and Molecular Responses to Obesity and Fetal Growth

Advanced Science, EarlyView.
Women with obesity often deliver large‐for‐gestational‐age (LGA) infants. Single‐nucleus RNA sequencing of term placenta reveals that hypoxia and TNF‐α signaling in syncytiotrophoblasts are featured in maternal obesity, but inflammatory signatures in Hofbauer cells and response to lipid or carbohydrate metabolism in fibroblasts are specific to LGA.

Complex Commingling: Nucleoporins and the Spindle Assembly Checkpoint

Cells, 2015
The segregation of the chromosomes during mitosis is an important process, in which the replicated DNA content is properly allocated into two daughter cells.

Overcoming inhibition in the spindle checkpoint. [PDF]

Genes & development, 2009
Spindle checkpoint silencing is a critical step during mitosis that initiates chromosome segregation, yet surprisingly little is known about its mechanism. Protein phosphatase I (PP1) was shown recently to be a key player in this process, and in this issue of Genes & Deverlopment, Akiyoshi and colleagues (pp.

Parabiosis, Assembloids, Organoids (PAO)

Advanced Science, EarlyView.
This review evaluates parabiosis, organoids, and assembloids as complementary disease models spanning systemic, organ, and multi‐organ levels. It highlights their construction strategies, applications, and current limitations, while emphasizing their integration with frontier technologies such as artificial intelligence, organ‐on‐a‐chip, CRISPR, and ...

Human kinetochores are swivel joints that mediate microtubule attachments

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

Mad1 kinetochore recruitment by Mps1-mediated phosphorylation of Bub1 signals the spindle checkpoint

Genes & Development, 2014
The mitotic spindle checkpoint ensures accurate chromosome segregation and genomic integrity. Understanding the regulation of checkpoint protein Mad1 recruitment to the kinetochore has been an outstanding question in the field.

HIDF: Integrating Tree‐Structured scRNA‐seq Heterogeneity for Hierarchical Deconvolution of Spatial Transcriptomics

Advanced Science, EarlyView.
The prevailing neglect of cellular hierarchies in current spatial transcriptomics deconvolution often obscures cellular heterogeneity and impedes the identification of fine‐grained subtypes. To address this issue, HIDF employs a cluster‐tree and dual regularization to systematically model cellular hierarchical structures.

CDK5RAP2 is required for spindle checkpoint function [PDF]

Cell Cycle, 2009
The combination of paclitaxel and doxorubicin is among the most successful chemotherapy regimens in cancer treatment. CDK5RAP2, when mutated, causes primary microcephaly. We show here that inhibition of CDK5RAP2 expression causes chromosome mis-segregation, fails to maintain the spindle checkpoint, and is associated with reduced expression of the ...
