histolysis

{{Short description|The breakdown of tissues}}

Histolysis is the decay and dissolution of organic tissues or of blood. It is sometimes referred to as histodialysis.[http://www.yourdictionary.com/histolysis histolysis] at YourDictionary.com. Accessed on 2011-07-09. In cells, histolysis may be caused by uracil-DNA degradation.{{cite book|title=Progress in Nucleic Acid Research and Molecular Biology, Volume 48|publisher=Academic Press|date=29 September 1994|url=https://books.google.com/books?id=kMOY8qD8wd0C|page=332|isbn=9780080863368}}

Origin: New Latin, from Greek {{lang|grc|‘ιστος}} (histos) tissue + {{lang|grc|λυσις}} (lusis) dissolution from {{lang|grc|λυειν}} to loosen, dissolve.

Histolysis is associated with metamorphosis as well as other morphological changes. The loss of organs or blood begins with cell death, which can be caused by a number of factors. In frogs, the histolysis of the tail associated with metamorphosis is also associated with a lowering of the pH of the blood.{{cite journal |last1=Dunihue |first1=F W |title=Histolysis and Regeneration of Anuran Tail Skin |journal=Biological Bulletin |date=1934 |volume=67 |issue=3 |doi=10.2307/1537520 |url=https://www.jstor.org/stable/1537520 |access-date=6 June 2021}}

Increases in histolysis has been found to correspond with the pupal phase of insect metamorphosis, wherein larval organs break down before the histogenesis of the adult tissues occur. The histolysis is associated with an increase in the production of ATP and a decrease in metabolism. {{cite journal |last1=Agrell |first1=Ivar |title=Histolysis, Histogenesis, and Differentiation during Insect Metamorphosis in Relation to Metabolic Changes |journal=Journal of Embryology and Experimental Morphology |date=September 1953 |volume=1 |issue=3 |pages=279–82 |url=http://dev.biologists.org/content/1/3/279 |accessdate=6 December 2018}}
