persin - The purified persin was examined using kauto IR NMR and UV spectroscopy and mass spectrometry and identified as ZZ1acetyloxy2hydroxy1215heneicosadien4one Persin has previously been isolated from avocado leaves and shown to have antifungal properties and to be toxic to silkworms Persin has recently been discovered to kill breast cancer cells It has also been shown to enhance the effect of the breast cancer fighting drug Tamoxifen This could potentially reduce the necessary dosage of current cancer drugs Persin is however highly insoluble and more research will be needed to put it into a soluble tablet form The phytochemical and pharmacological profile of Persea May 2 2019 Avocado contains persin a substance that can cause vomiting diarrhea and serious symptoms in some animals Learn how to prevent and treat avocado poisoning in dogs birds horses ruminants and more 20 hours ago LAFAYETTE Ind Tippecanoe Circuit Judge Sean Persin heard from two courtappointed physicians who believed that the Purdue murder suspect Ji Jimmy Min Sha is incompetent to stand trial After briefly evaluating his behavior in the jail and reviewing his extensive medical and jail records Persin 15 2R12Z15Z2hydroxy4oxoheneicosa1215dienyl acetate a constituent of avocado leaves is regarded as a toxin for lactating livestock In addition persin has been found to reduce the larval growth of the beet armyworm Spodoptera exigua and is a known antifungal agent against Colletotrichum gloeosporioides The toxic principle identified in avocado is persin When isolated from leaves this compound caused mastitis in lactating mice at 60 mgkg and myocardial necrosis at 100 mgkg Sheep fed 25 gkg body weight for 32 days developed cardiac insufficiency Guatemalan varieties are more commonly associated with symptoms and are thought to be more toxic Why Is Persin Not Toxic To Humans Vet Explains Pets Persin ist ein Acetogenin ein Toxin aus der Gruppe der Polyketide ein Fettsäurederivat welches beispielsweise in den Blättern der Avocado Persea americana enthalten ist 3 Der Trivialname leitet sich auch vom Gattungsnamen Persea der Avocado ab CD1 female and male mice will be used in a complete randomized design and orally dosed with either vehicle tocopherol stripped corn oil 0 persin avocado oil or labeledpersin at 10 low or 100 high mg of persinkgday for a total of either 10 days or 30 days to reflect acute vs chronic exposure to this toxin Natural antifungal in avocados believed to cause sudden death 19 hours ago Persin said he will set a hearing on Shas criminal case at the request of either Shas attorneys or prosecutors For now his murder case is stayed Reach Ron Wilkins at rwilkinsjconlinecom The Odyssey of Bioactive Compounds in Avocado Persea Jun 25 2007 Persin is a compound found in the leaves and fruit of the avocado tree that can selectively kill breast cancer cells by raising their levels of a killer protein Researchers at Garvan Institute of Medical Research are studying its potential as a new therapeutic agent for breast cancer Persin Wikipedia Persin is a fungicidal toxin present in the avocado 1 Persin is an oilsoluble compound structurally similar to a fatty acid a colourless oil and it leaches into the body of the fruit from the seeds The relatively low concentrations of persin in the ripe pulp of the avocado fruit is generally considered harmless to humans Ingestion of persin isolated from avocado leaves has caused lesions similar to those reported in cases of avocado ingestion Clinical Findings of Avocado Persea spp Toxicosis in Animals In lactating animals sterile mastitis accompanied by a 75 decrease in milk production occurs within 24 hours after avocado ingestion Here we describe the characterization of a novel plant toxin persin with in vivo activity in the mammary gland and a p53 estrogen receptor and Bcl2independent togel binatang pemalu mode of action Persin was previously identified from avocado leaves as the toxic principle responsible for mammary glandspecific necrosis and apoptosis in lactating livestock Dec 10 2013 Persininduced apoptosis is associated with an increase in markers of ERS To further explore the mechanistic basis of persininduced cytotoxicity we examined components of ERS signalling pathways in two persinsensitive human breast cancer cell lines MCF7 and T47D using the known ERS inducer tunicamycin as a positive control Role of endoplasmic reticulum stress induction by the plant Avocado Poisoning in Dogs Symptoms Causes Diagnosis Yes persin can be harmful to certain animals such as birds and horses It is important to keep avocados away from pets that are sensitive to persin to prevent any potential health problems 9 Can persin cause skin irritation While persin is a fungicidal toxin it is unlikely to cause skin irritation in humans Avocado Is Toxic To Dogs Pet Poison Helpline Guide to Poisonous Plants Colorado State University Jan 4 2017 Persin is known to attack the mitochondria structures inside a cell that generate energy According to Duke veterinary pathologist Jeffrey Everitt who examined tissue samples under a microscope While dogs and cats are rarely affected by persin avocado poisoning can be deadly to birds and large animals such as cows goats sheep The bigger risk to dogs and cats is a foreign body obstruction in the esophagus stomach or intestinal tract if part or all of a large avocado seed is swallowed Persin C23H40O4 CID 6443027 structure chemical names physical and chemical properties classification patents literature biological activities safety Jun 23 2019 Persin is an oilsoluble compound found in the leaves and bark of the avocado plant as well as the pits It acts as a natural fungicide While the amount of persin in an avocado pit isnt enough to harm a human avocado plants and pits can harm pets and livestock Cats and dogs may become slightly ill from eating avocado flesh or seeds The Scoop on Avocado and Your Pets ASPCA Avocado Persea spp Toxicosis in Animals Toxicology Understanding Toxins in Avocado Seeds ThoughtCo Persin is a fungicidal toxin found in both the fruit and leaves of the avocado tree Persea americana It has been isolated only recently and discovered to kill breast cancer cells It has also been shown to enhance the effect of the breast cancer fighting drug Tamoxifen This could potentially reduce the necessary dosage of current cancer drugs Persin In vitro MDAMB231 MCF7 and T47D breast cancer cells In vivo Quackenbush lactating mice In vitro Persin selectively arrested cells at the G 2 M phase and induced caspasedependent apoptosis Apoptosis was dependent on the expression of Bim protein which also indicated the microtubulestabilizing properties of persin Jun 16 2016 Avocado poisoning in dogs occurs when dogs ingest the pit of an avocado The avocado pit contains a poisonous substance called persin and when ingested can cause dogs to become ill The avocado is potentially toxic with the leaf being of most danger Can Dogs Eat Avocado American Kennel Club Isolation and identification of a compound from avocado Persin wikidoc Purdue murder suspects mental health history
