Regulation of ROCK1 via Notch1 during breast cancer cell migration into dense matrices

BMC Cell Biology, 2012
Background The behaviour of tumour cells depends on factors such as genetics and the tumour microenvironment. The latter plays a crucial role in normal mammary gland development and also in breast cancer initiation and progression.

Anticipation of periodic events influences cell motility in amoeba proteus

Scientific Reports
All migrating cells (both single-cell organisms and as part of multicellular organisms) sense environmental conditions and respond to physical and molecular cues by changing the direction and speed of cellular movement.

Plant-specific tail-anchored coiled-coil protein MAG3 stabilizes Golgi-associated ERESs to facilitate protein exit from the ER

Communications Biology
Endoplasmic reticulum exit sites (ERESs) are ER subdomains where coat protein complex II carriers are assembled for ER-to-Golgi transport. We previously proposed a dynamic capture-and-release model of ERESs by Golgi stacks in plants.

Secretion and endocytosis in subapical cells support hyphal tip growth in the fungus Trichoderma reesei

Nature Communications
Filamentous fungi colonise substrates by invasive growth of multi-cellular hyphae. It is commonly accepted that hyphae expand by tip growth that is restricted to the first apical cell, where turgor pressure, exocytosis and endocytosis cooperate to expand

Insight into the Interactions Between GhXI-K and Rab GTPases in Cotton Fiber

Plants
Myosin XI-K plays an important role in cell expansion and polarized growth, acting as a motor protein that drives organelle trafficking and cytoplasmic streaming.

Principles of organelle positioning in motile and non-motile cells

EMBO Reports
Cells are equipped with asymmetrically localised and functionally specialised components, including cytoskeletal structures and organelles. Positioning these components to specific intracellular locations in an asymmetric manner is critical for their ...

Recovery of the cortical chloroplast layer in the green alga Chara after local irradiation

Frontiers in Plant Science
The cytoplasm of characean internodal cells is characterized by a stationary layer of cortical chloroplast files and a mobile endoplasm moving along subcortical actin bundles.
