Heat shock proteins induced by the HSR can help prevent protein aggregation that is associated with common neurodegenerative diseases such as Alzheimer's, Huntington's, or Parkinson's disease. [8] The diagram depicts actions taken when a stress is introduced to the cell. Stress will induce HSF-1 and cause proteins to misfold.
Heat shock proteins (HSPs) are a family of proteins produced by cells in response to exposure to stressful conditions. They were first described in relation to heat shock, [1] but are now known to also be expressed during other stresses including exposure to cold, [2] UV light [3] and during wound healing or tissue remodeling.

This interaction sets off a chain of additional chemical reactions that form a blood clot. [8] Factor VIII participates in blood coagulation; it is a cofactor for factor IXa, which, in the presence of Ca 2+ and phospholipids, forms a complex that converts factor X to the activated form Xa. The factor VIII gene produces two alternatively spliced ...
In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiation, or heat.

ETP-based activated protein C resistance test (ETP-based APCR) Thrombodynamics test. Non-homogenous: realization of the three-dimensional model of the clot growth; Use of platelet free plasma; Record of information about the clot formation as a diagram, giving the possibility to calculate the key parameters of the blood coagulation system
Coagulation factor VII (EC 3.4.21.21, formerly known as proconvertin) is a protein involved in coagulation and, in humans, is encoded by gene F7. It is an enzyme of the serine protease class. Once bound to tissue factor released from damaged tissues, it is converted to factor VIIa (or blood-coagulation factor VIIa , activated blood coagulation ...
The words protein, polypeptide, and peptide are a little ambiguous and can overlap in meaning. Protein is generally used to refer to the complete biological molecule in a stable conformation, whereas peptide is generally reserved for a short amino acid oligomers often lacking a stable 3D structure. But the boundary between the two is not well ...
Coagulation factor V (Factor V), also less commonly known as proaccelerin or labile factor, is a protein involved in coagulation, encoded, in humans, by F5 gene. [5] In contrast to most other coagulation factors, it is not enzymatically active but functions as a cofactor . [ 5 ]
