Single moleculesIn vitro motility assayMyosinActinMonte-Carlo simulationBridging the gaps between experimental systems on different hierarchical scales is needed to overcome remaining challenges in the understanding of muscle contraction. Here, a mathematical model with w...
How do cells use energy? Select all that apply a. active transport ATP b. hydrolysis c. biosynthesis of more complex molecules d. D1 muscle contraction Which of the following is a true statement about ATP? 1) ATP is produced when ADP releases energy. 2)...
(d) Any two from: • (walls of) veins more than one layer of cells and capillaries one layer/eq • (walls of) veins contain connective tissue/(smooth) muscle/collagen/elastic tissue, capillaries do not/eq • veins have valves in them and capillaries do not/eq • ...
b.Things dissolved in water (sugars like glucose, and energy molecules =ATP) c.Cytoskeleton: made up of long proteinfibers that extend throughout cytoplasm. Function of cytoskeleton: 1)Maintains cell shape 2)Movement (such as muscle cell contraction, organelles within the cell, or the cell it...
Abstract Plectin, as the cytolinker and scaffolding protein, are widely expressed and abundant in many tissues, and has involved in various cellular activities contributing to tumorigenesis, such as cell adhesion, migration, and signal transduction. Due to the specific expression and differential locali...
Explain the first of Koch's postulates that states "the pathogens thought to cause the disease must be present in every case in which the disease is found." Explain the principle of gaseous exchange in the lungs. Explain the sliding filament and ratchet mechanism in skeletal muscle contraction,...
Other important integrin–ligand associations in atherogenesis The vascular smooth muscle cell regulates the extracellular matrix through binding of collagen to β1 integrins on the smooth muscle cell. The integrins α1β1 and α2β1 both participate in adhesion to collagen and are synergistic in fun...
remodeling in CAFs, leading to increased fibrillar collagen deposition, and promoting their pro-malignant functions [108]. Interestingly, in 3D collagen, the same level of hypoxia (1% oxygen, 72-hr) inhibits PHD2, stabilizes HIF-1α, reduces the expressions of alpha‐smooth muscle actin (αSMA...
In multicellular organisms, cell-cell contacts within a tissue as well as contacts between cells and the extracellular matrix, which scaffolds the tissue, are indispensably required for the physiological function of the tissue and its development. These cell-cell and cell-matrix interactions are medi...
