Guest guest Posted September 25, 2006 Report Posted September 25, 2006 (remember Trichathecene mycotoxin exposure effects are compared to radiation exposure.) (ROS) REATIVE OXYGEN SPECIES MEDIATES CELLULAR DAMAGE, EFFECTS OF (GSH) HEPATOCELLULAR GLUTATHIONE,SURVIVAL AND INTEGRITY OF NUCLEAR MITOCHONDRIAL DNA(mtDNA) IN HUMAN HEPATOBLASTOMA CELLS FROM RADIATION EXPOSUREradiation resulted in a dose-dependent generation of (ROS),accompanied by a decrease of (GSH). depletion of (GSH) prior to radiation increased (ROS). depletion of (GSH) bt radiation was apparent in different subcellular sites, particularly significant in mitochondria. depleted (GSH) resulted in DNA fragmentation and apoptosis. (GSH) cells were also reduced. cellular (GSH) is a factor in deturmining intrinsic sensativity.mtDNA displayed an increased loss of integrity and was potentiated by (GSH) depletion in mitochandria. CONCLUSION-GSH PLAYS A CRITIAL PROTECTIVE ROLE IN MAINTAINING NUCLEAR AND mtDNA FUNCTIONAL INTEGRITY AND INTRINSIC SENSATIVITY. GSH ay not be involved in DNA damage repairing but may relate to modification of DNA damage dependent signaling. ..http://www.osti.gov/energycitations/product.biblio.jsp? osti_id=20429033 OXIDATIVE STRESS, MITOCHANDRAIL DNA MUTATION,MITOCHONDRAIL RESPIRATORY SYSTEM,BRAIN AND MATABOLISM,ENERGY AFFECTS,PREMATURE AGING AND DEATH. oxidative stress,mitochondrial DNA utation and impairent of antioxidant enzymes in aging <http://www.sciencedirect.com/science?_ob=ArticleURL & _udi=B6WX0- 45BBXH5-5 & _user=10 & _handle=V-WA-A-W-AC-MsSAYWA-UUA-U-AAZACUBCDW- AACEUYVBDW-AVCEAVCED-AC-U & _fmt=summary & _coverDate=12%2F31% 2F2001 & _rdoc=5 & _orig=browse & _srch=%23toc%237144%232001%23999879993% 23289330! & _cdi=7144 & view=f & _acct=C000050221 & _version=1 & _urlVersion=0 & _userid=10 & md5=102474fef4f25226a4a58e6bb824d1d5> reactive oxygen species and mitochondrial diseases <http://www.medscape.com/medline/abstract/11735379> MYCOTOXINS (I highly recomend reading this, goes into mycotoxins in detail) good coverage on T-mycotoxins <http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=164220> mycotoxins can be classified as hepatotoxins,nephrotoxins,neurotoxins, immunotoxins and so forth. cell biologests put them into generic groups such as tetatogens,mutagens,carcinogens and allergens. MYCOTOXICOSIS-can be acute or chronic. acute toxicity has rapid onst and obivous responce, while chronic toxicity is characterized by low- dose long term exposure resulting in cancers and other generally irreversible effects. <http://www.chronicfatiguesupport.com/library/showarticle.cfm/id/6679> brain and heart heart muscles have the greatest mitochondrial content of any tissue in the body. neurons have far less mitochondria and run out long before the heart. mitochandrail diseases <http://www.umdf.org/mito_info/genetics.aspx> inherited mitochondrial disorders usually result in severe disease with infantile onset. sporadic cases- not all mitochandrail diseases are inherited mitchondrail diseases <http://www.tsbvi.edu/Outreach/seehear/spring02/mitochondrial.htm> mitochandrail disorders <http://www.neuro.wustl.edu/neuromuscular/mitosyn.html> COX deiiciency-it is possible may be do to abnormal changes( mutation) of mitochoundria(mtDNA) <http://www.webmd.com/hw/raising_a_family/nord1088.asp> .. carnitine deficiency <http://www.emedicine.com/ped/byname/carnitine-deficiency.htm> <http://www.moderntherapy.com/micronutrients.html> <http://www.baylor.edu/biomedical_studies/index.php?id=18701> <http://www.baylorhealth.edu/imd/support.htm> matabolic disease disorders,tests <http://www.baylorhealth.edu/imd/researchtests.htm> <http://www.baylorhealth.edu/imd/researchtests/glutathione.htm> (GSH) <http://www.baylorhealth.edu/imd/clinicaltests/homocysteine.htm> <http://www.baylorhealth.edu/imd/researchtests/monoamine.htm> neurotransmitters <http://www.baylorhealth.edu/imd/researchtests/hcmgene.htm> (PCR) gene mutation Quote
