(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 •...
function. Also troponin is a protein that is important to create muscle contraction. This affects the function of muscle contraction because it gives it the tension that makes it shorten. The structure of a protein affects cell signaling because a receptor signals cells are located in the plas...
in which suppression of contractile markers, enhanced proliferation, and migration lead to the progression of aberrant vascular remodeling. Since many types of guidance molecules are expressed in vascular smooth muscle and pericytes, these may contribute to blood vessel formation and aberrant remodeling du...
cells release neurotransmitters or biochemicals, leading to contraction or relaxation of muscle cells, cytoskeletal formation, or remodeling. Cell death is the final event of the cell life cycle, which can occur in a local and a certain number of groups in order to maintain the overall benefit....
In response to cellular injury, endothelial cells produce growth factors that induce smooth muscle cells to proliferate. The “response-to-injury hypothesis,” initially proposed by Ross and Glomset in the 1970s 29, 30, 31, 32, suggests that atherosclerosis results from some form of injury to ...
Gap junctions unite muscle cells in the heart to help coordinate their contraction. Model of a gap junction. The lipid bilayers are penetrated by protein assemblies called connexons. Two connexons join across the intercellular space to form a continuous aqueous channel that links the two cells....
PI3-kinase is indeed involved in the myosin-induced “purse-string-like” contraction of pseudopods that closes phagosomes (Swanson et al, 1999). The exact role of the FcγRIII receptor, anchored via a C-terminus-linked GPI moiety in the neutrophil membrane, is not yet clear. It has ...
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...
Muscle Fiber: Structures, Contraction & Relaxation from Chapter 13 / Lesson 3 8.8K In this lesson, we will explore how muscle contraction and relaxation takes place, address the role & importance of calcium in this process, and will be able to summarize The Slid...
