text: Proper control of division orientation and symmetry, largely determined by
spindle positioning, is essential to development and homeostasis. Spindle positioning
has been extensively studied in cells dividing in two-dimensional (2D) environments
and in epithelial tissues, where proteins such as NuMA (also known as NUMA1) orient
division along the interphase long axis of the cell. However, little is known
about how cells control spindle positioning in three-dimensional (3D) environments,
such as early mammalian embryos and a variety of adult tissues. Here, we use mouse
embryonic stem cells (ESCs), which grow in 3D colonies, as a model to investigate
division in 3D. We observe that, at the periphery of 3D colonies, ESCs display
high spindle mobility and divide asymmetrically. Our data suggest that enhanced
spindle movements are due to unequal distribution of the cell–cell junction protein
E-cadherin between future daughter cells. Interestingly, when cells progress towards
differentiation, division becomes more symmetric, with more elongated shapes in
metaphase and enhanced cortical NuMA recruitment in anaphase. Altogether, this
study suggests that in 3D contexts, the geometry of the cell and its contacts
with neighbors control division orientation and symmetry.

text: Coordinated cell polarization in developing tissues is a recurrent theme in
multicellular organisms. In plants, a directional distribution of the plant hormone
auxin is at the core of many developmental programs. A feedback regulation of
auxin on the polarized localization of PIN auxin transporters in individual cells
has been proposed as a self-organizing mechanism for coordinated tissue polarization,
but the molecular mechanisms linking auxin signalling to PIN-dependent auxin transport
remain unknown. We performed a microarray-based approach to find regulators of
the auxin-induced PIN relocation in the Arabidopsis thaliana root. We identified
a subset of a family of phosphatidylinositol transfer proteins (PITP), the PATELLINs
(PATL). Here, we show that PATLs are expressed in partially overlapping cells
types in different tissues going through mitosis or initiating differentiation
programs. PATLs are plasma membrane-associated proteins accumulated in Arabidopsis
embryos, primary roots, lateral root primordia, and developing stomata. Higher
order patl mutants display reduced PIN1 repolarization in response to auxin, shorter
root apical meristem, and drastic defects in embryo and seedling development.
This suggests PATLs redundantly play a crucial role in polarity and patterning
in Arabidopsis.

text: A change regarding the extent of adhesion - hereafter referred to as adhesion
plasticity - between adhesive and less-adhesive states of mammalian cells is important
for their behavior. To investigate adhesion plasticity, we have selected a stable
isogenic subpopulation of human MDA-MB-468 breast carcinoma cells growing in suspension.
These suspension cells are unable to re-adhere to various matrices or to contract
three-dimensional collagen lattices. By using transcriptome analysis, we identified
the focal adhesion protein tensin3 (Tns3) as a determinant of adhesion plasticity.
Tns3 is strongly reduced at mRNA and protein levels in suspension cells. Furthermore,
by transiently challenging breast cancer cells to grow under non-adherent conditions
markedly reduces Tns3 protein expression, which is regained upon re-adhesion.
Stable knockdown of Tns3 in parental MDA-MB-468 cells results in defective adhesion,
spreading and migration. Tns3-knockdown cells display impaired structure and dynamics
of focal adhesion complexes as determined by immunostaining. Restoration of Tns3
protein expression in suspension cells partially rescues adhesion and focal contact
composition. Our work identifies Tns3 as a crucial focal adhesion component regulated
by, and functionally contributing to, the switch between adhesive and non-adhesive
states in MDA-MB-468 cancer cells.
