cell migration

A study published in Nature reports that the structural state of the microtubule lattice regulates Rho GTPase signalling. The finding links the physical configuration of cellular microtubules to a key pathway controlling cell shape, adhesion and migration. It offers researchers a new angle on how the cytoskeleton communicates with signalling networks inside cells.

Researchers have described a newly identified population of extracellular vesicles, named motile vesicles (MoVes), which are associated with cancer cell migration. The finding suggests these vesicles may play a role in how cancer cells move and potentially spread, opening new avenues for research into metastasis and possible therapeutic targets.

Researchers report that migrating cancer cells release giant vesicles containing whole genomes, adding to what is known about how tumours shed genetic material as they move through the body. The finding could have implications for understanding cancer spread and for liquid biopsy approaches that detect tumour DNA in circulation.

Researchers report that calcium signals switch mitochondrial motors that power filopodia, the thin projections cells use to probe their environment, thereby driving cell migration. The finding links calcium signalling, mitochondrial positioning and cell movement in a single mechanism, and could inform studies of wound healing, immune response and cancer invasion, where migrating cells play a central role.

New research reports that tumor cells move more readily and escape when grown on disordered, irregular substrates rather than uniform surfaces, based on simplified laboratory models. The finding suggests tissue disorganization may play a role in cancer cell migration and invasion, offering a possible avenue for studying how tumors spread beyond their original site.
