Temperature-Dependent Elasticity of Microtubules [PDF]

open access: yes, 2008
Central to the biological function of microtubules is their ability to modify their length which occurs by addition and removal of subunits at the ends of the polymer, both in vivo and in vitro. This dynamic behavior is strongly influenced by temperature.

Unbiased pattern analysis reveals highly diverse responses of cytoskeletal systems to cyclic straining.

open access: yesPLoS ONE, 2019
In mammalian cells, actin, microtubules, and various types of cytoplasmic intermediate filaments respond to external stretching. Here, we investigated the underlying processes in endothelial cells plated on soft substrates from silicone elastomer.

Dissecting the molecular mechanism underlying the intimate relationship between cellulose microfibrils and cortical microtubules

open access: yesFrontiers in Plant Science, 2014
A central question in plant cell development is how the cell wall determines directional cell expansion and therefore the final shape of the cell. As the major load-bearing component of the cell wall, cellulose microfibrils are laid down transversely to ...

Formins and microtubules

open access: yesBiochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2010
Formins have recently been recognized as prominent regulators of the microtubule (MT) cytoskeleton where they modulate the dynamics of selected MTs in interphase and mitosis. The association of formins with the MT cytoskeleton and their action on MT dynamics are relatively unexplored areas, yet growing evidence supports a direct role in their ...

The multifaceted roles of lysosomes in cancer

open access: yesMolecular Oncology, EarlyView.
Lysosomes support cancer cell adaptation by integrating macromolecule degradation and nutrient recycling with nutrient sensing, inter‐organelle communication and immune regulation. These interconnected functions can promote tumour growth, stress tolerance and therapy resistance, while also creating context‐dependent vulnerabilities that may be ...

MATCAP1 preferentially binds an expanded tubulin conformation to generate detyrosinated and ΔC2 α-tubulin

open access: yesThe EMBO Journal
Microtubules are cytoskeletal filaments with critical roles in cell division, cell motility, intracellular trafficking, and cilium function. In cells, subsets of microtubules are selectively marked by posttranslational modifications (PTMs) that control ...

Cytoplasmic Dynein Transports Axonal Microtubules in a Polarity-Sorting Manner

open access: yesCell Reports, 2017
Axonal microtubules are predominantly organized into a plus-end-out pattern. Here, we tested both experimentally and with computational modeling whether a motor-based polarity-sorting mechanism can explain this microtubule pattern.

Microtubules born on microtubules

open access: yesThe Journal of Cell Biology, 2005
![Graphic][1] A new MT is nucleated (white arrowhead) by a γ-TuC (green) that sits on an existing MT bundle.Microtubule (MT) arrays form, say Janson et al. ( [page 297][2]), when MT nucleators stick to existing MTs.

Small RNA pathways in mammalian oocytes

open access: yesFEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Interplay between kinesin-1 and cortical dynein during axonal outgrowth and microtubule organization in Drosophila neurons

open access: yeseLife, 2015
In this study, we investigated how microtubule motors organize microtubules in Drosophila neurons. We showed that, during the initial stages of axon outgrowth, microtubules display mixed polarity and minus-end-out microtubules push the tip of the axon ...
