Reliable and robust control of nucleus centering is contingent on nonequilibrium force patterns

iScience, 2023
Summary: Cell centers their division apparatus to ensure symmetric cell division, a challenging task when the governing dynamics is stochastic. Using fission yeast, we show that the patterning of nonequilibrium polymerization forces of microtubule (MT ...

CD168 Identifies Proliferating Pancreatic Islet Cells in Murine and Human

Advanced Science, EarlyView.
This study identifies CD168 as a conserved surface marker for proliferating β‐cells in mouse, human islets, and pancreatic islet tumors. CD168⁺ cells show high proliferation and low insulin expression. CD168+ cells form mostly uni‐β lineage clones, and some of the clones are multi‐lineage.

An Extended, Boolean Model of the Septation Initiation Network in S.Pombe Provides Insights into Its Regulation. [PDF]

PLoS ONE, 2015
Cytokinesis in fission yeast is controlled by the Septation Initiation Network (SIN), a protein kinase signaling network using the spindle pole body as scaffold.

Computational identification of transcription factor binding sites by functional analysis of sets of genes sharing overrepresented upstream motifs [PDF]

, 2004
BACKGROUND: Transcriptional regulation is a key mechanism in the functioning of the cell, and is mostly effected through transcription factors binding to specific recognition motifs located upstream of the coding region of the regulated gene.

PFOS Disrupts Oocyte Maturation and Early Embryonic Development via Ovarian FOXK1 O‐GlcNAcylation in Mice

Advanced Science, EarlyView.
Perfluorooctane sulfonate (PFOS) exposure disrupts oocyte maturation and early embryonic development. This study elucidates the mechanism by which enhanced O‐GlcNAcylation of FOXK1 underlies the PFOS‐induced reduction of progesterone levels in granulosa cells and the disturbance of follicular microenvironment.

Mitotic-Spindle Organizing Protein MztA Mediates Septation Signaling by Suppressing the Regulatory Subunit of Protein Phosphatase 2A-ParA in Aspergillus nidulans

Frontiers in Microbiology, 2018
The proper timing and positioning of cytokinesis/septation is crucial for hyphal growth and conidiation in Aspergillus nidulans. The septation initiation network (SIN) components are a conserved spindle pole body (SPB) localized signaling cascade and the
