Peptide‐Induced Ferroelectricity in Charge‐Transfer Supramolecular Materials

Advanced Materials, EarlyView.
Bio‐inspired supramolecular charge‐transfer amphiphiles self‐assemble into nanoribbons in water, where peptide chirality‐induced symmetry breaking generates robust ferroelectricity across multiple systems. These water‐processable organic ferroelectrics also enhance neuronal outgrowth and electrophysiological maturity, offering a versatile strategy for ...

Self-organized dynamics and the transition to turbulence of confined active nematics

, 2019
We study how confinement transforms the chaotic dynamics of bulk microtubule-based active nematics into regular spatiotemporal patterns. For weak confinements, multiple continuously nucleating and annihilating topological defects self-organize into ...

Altered chemomechanical coupling causes impaired motility of the kinesin-4 motors KIF27 and KIF7. [PDF]

, 2018
Kinesin-4 motors play important roles in cell division, microtubule organization, and signaling. Understanding how motors perform their functions requires an understanding of their mechanochemical and motility properties.

Association of p60c-src with endosomal membranes in mammalian fibroblasts. [PDF]

, 1992
We have examined the subcellular localization of p60c-src in mammalian fibroblasts. Analysis of indirect immunofluorescence by three-dimensional optical sectioning microscopy revealed a granular cytoplasmic staining that co-localized with the microtubule

Evolution of microtubule organizing centers across the tree of eukaryotes [PDF]

The Plant Journal, 2013
SummaryThe architecture of eukaryotic cells is underpinned by complex arrrays of microtubules that stem from an organizing center, referred to as the MTOC. With few exceptions, MTOCs consist of two basal bodies that anchor flagellar axonemes and different configurations of microtubular roots.

Phase‐Separation of YAP Mediates AJUBA Super Enhancer Activation to Promote Aberrant Mitosis in Breast Cancer

Advanced Science, EarlyView.
YAP undergoes phase separation to activate the AJUBA super‐enhancer, driving aberrant mitosis through spindle checkpoint dysregulation in breast cancer. This study uncovers a mechanistic link between YAP condensates, super‐enhancer activation, and aneuploidy formation.

Parafibromin governs cell polarity and centrosome assembly in Drosophila neural stem cells.

PLoS Biology, 2022
Neural stem cells (NSCs) divide asymmetrically to balance their self-renewal and differentiation, an imbalance in which can lead to NSC overgrowth and tumor formation. The functions of Parafibromin, a conserved tumor suppressor, in the nervous system are

CCDC41 Drives Oocyte Meiotic Progression by Promoting Rab11a/Rab7‐Positive Vesicle Fusion with Target Membranes

Advanced Science, EarlyView.
CCDC41 is essential for meiotic maturation in mouse oocytes through regulating Rab7‐positive endosomes fusion with lysosomes and Rab11a‐positive vesicle fusion with the plasma membrane. Abstract Coiled‐coil domain‐containing protein 41 (CCDC41), a core component of centriolar distal appendages involved in centriole assembly and ciliary vesicle docking,

The microtubule cross-linker Feo controls the midzone stability, motor composition, and elongation of the anaphase B spindle in Drosophila embryos. [PDF]

, 2015
Chromosome segregation during anaphase depends on chromosome-to-pole motility and pole-to-pole separation. We propose that in Drosophila embryos, the latter process (anaphase B) depends on a persistent kinesin-5-generated interpolar (ip) microtubule (MT)
