microfilament

 [mi″kro-fil´ah-ment]
any of the submicroscopic filaments, composed chiefly of actin, found in the cytoplasmic matrix of almost all cells, often in close association with the microtubules.

mi·cro·fil·a·ment

(mī'krō-fil'ă-ment),
The finest filamentous element of the cytoskeleton, having a diameter of about 5 nm and consisting primarily of actin.
See also: actin filament.

microfilament

(mī′krō-fĭl′ə-mənt)
n.
Any of the actin-containing filaments that are found in the cytoplasm of eukaryotic cells and are involved in generating cell movement, providing structural support, and organizing internal cell components. Microfilaments, along with intermediate filaments and microtubules, make up a cell's cytoskeleton.

mi′cro·fil′a·men′tous (-mĕn′təs) adj.

microfilament

Any of a group of elongated, 5–7 nm in diameter, cytoplasmic fibres composed predominantly of actin, which form a cytoskeletal latticework.

mi·cro·fil·a·ment

(mī'krō-fil'ă-mĕnt)
The finest filamentous element of the cytoskeleton, having a diameter of about 5 nm and consisting primarily of actin.

microfilament

a fine, subcellular structure about 5–8 nm in diameter, composed of ACTIN or a similar protein and found in the cytoplasm of EUKARYOTE cells. Microfilaments are able to contract and are also involved in CYTOPLASMIC STREAMING and PHAGOCYTOSIS.

We document the significant alterations in microtubule and microfilament networks in MDA-treated cells, which is consistent with its suppression of cortical cytoplasm motility, the loss of cellular contacts, and increased permeability to macromolecules.
In May, Freudenberg Performance Materials unveiled Evolon 3D, a variation of its Evolon microfilament fabric.
Because mRNA expression for Apc, Espn, Cdh2, and Vim was unchanged at E21.5 after DBP exposure (Figure 4), we presume that the DBP-induced microfilament changes resulted from protein redistribution, although DBP-induced protein degradation and/or translational regulation cannot be excluded.
Figure 2a and c displays the transverse cross-sectional areas of the oriented nanocomposites, i.e., also the cross-section of the original microfilaments. The nanomodifiers are primarily normal to the viewed plane, which shows a preferred orientation in the direction of flow (also normal to the viewing plane).
Ultrastructural changes occurred prior to massive proteinuria, including diffuse podocyte foot process effacement, swelling of the mitochondria, and disarrangement of microfilaments. YQQRG attenuated these pathological changes, exhibiting a protective effect on GFB structure, an effect equivalent to that of fosinopril.
Inorganic Se was more effective in reducing cell growth and mechanism of action involving proteins, nuclear, microfilaments, and microtubule damage than those provoked by SeMet, even when SeMet is more bioavailable than SSe.

P-cells usually have two nuclei with a mass of short, delicate microfilaments scattered randomly in the cytoplasm; they contain short sarcomeres and myofibrillar insertion plaque.
