What are the first steps in invadopodia assembly and disassembly?

What is the first step in invadopodia assembly? Initiation of invadopdia formation is highly complex, being influenced by various signalling cascades and phosphorylation events that occur following detection of a stimulant. For example, activation [...]

What are podosomes?

What are podosomes? Podosomes are actin-rich, adhesive structures that are present at the ventral surface of cells of the monocytic myeloid lineage, stimulated endothelial cells [1] and cultured Src-transformed cancer cells. These structures are [...]

What are the functions of podosomes?

What are the functions of podosomes? Both focal adhesions and podosomes are intimately involved in cell motility, with podosomes specifically implicated in cell invasion. Invasiveness is achieved through the secretion of matrix metalloproteinases (MMPs) [...]

What is the first step in podosome assembly?

What is the first step in podosome assembly? Podosome initiation and assembly is highly regulated, both spatially and temporally. Dendritic cells best exemplify the temporal regulation of podosome formation. Following activation by an antigen [...]

What is the function of stress fibers?

What is the function of stress fibers? Stress fibers are contractile in nature. By exerting and maintaining tension on the underlying substratum, they form a key element of the mechanotransduction apparatus that links the [...]

What mechanisms drive invadopodia extension?

What mechanisms drive invadopodia extension? Following initiation by an appropriate signal, the actin cytoskeleton is reorganized to facilitate invadopodia formation. Although several kinases and GTPases are known to influence the transduction of extracellular signaling [...]
